OBJECTIVE: To study the efficacy of a simple protocol
of natural cycle in vitro fertilization. METHOD: A
retrospective study of 59 natural treatment cycles
in 37 infertile couples with previous unsuccessful
attempts of conventional in vitro fertilization. RESULTS:
In 24% of cycles, the aspiration was cancelled because
of inadequate visualization of follicles or because
of preterm ovulation. Aspiration was performed in
45 cycles with oocyte retrieval of 82% per aspiration.
Embryo transfer was performed in 30 cycles, pregnancy
rate per pick-up was 15%. CONCLUSION: In vitro fertilization
in a natural cycle is a simple, relatively cheap and
comfortable procedure with reasonable results and
can be offered to patients scheduled not only for
in vitro fertilization because of tubal factor but
also to patients with endometriosis or unexplained
infertility.

BACKGROUND: There is strong evidence that locally
secreted cytokines control the implantation process
and can cause implantation failure. Uterine flushing
fluids were analysed to determine their concentrations
of leukaemia inhibitory factor (LIF) and tumour necrosis
factor (TNF). METHODS AND RESULTS: We began by flushing
the uterine cavities of 33 infertile patients on day
26 of two consecutive cycles. The concentrations of
LIF (by enzyme-linked immunosorbent assay) and TNF
(by bioassay) were significantly correlated during
these cycles (r = 0.762, P = 0.0001 and r = 0.822,
P = 0.001 respectively) and hence reliable. Then,
after a reference flushing of 30 infertile patients,
we followed the outcome of their first consecutive
cycle of ovarian stimulation, which preceded either
IVF or intrauterine insemination. A total of 10 patients
became pregnant. The median concentration of LIF was
0 pg/ml (range: 0-177) and of TNF was 0 U/ml (range:
0-6.17) among those who became pregnant, and 203 pg/ml
(range: 0-1620) and 2.14 U/ml (range: 0-16) respectively
among those who did not. The LIF concentration was
significantly lower in the pregnant group (P = 0.0013).
CONCLUSION: A low concentration of LIF in the uterine
flushing fluid at day 26 was predictive of subsequent
implantation. Use of this procedure should increase
the number of IVF attempts yielding successful pregnancies
and also lead to corrective therapies.

Acute ureteral obstruction following transvaginal
oocyte retrieval for IVF. Miller PB, Price T, Nichols
JE Jr, Hill L
Center for Women's Medicine, Division of Reproductive
Endocrinology and Infertility, Greenville, South
Carolina, USA. pmiller@ghs.org
Transvaginal, ultrasound-guided oocyte retrieval has
become the gold standard for IVF therapy. Despite
a low reported complication rate, here a case is reported
of acute ureteral obstruction following seemingly
uncomplicated oocyte retrieval. Prompt diagnosis and
ureteral stenting led to rapid patient recovery with
no long-term urinary tract sequelae. Ureteral injury
needs to be included in the differential diagnosis
of a patient presenting with pelvic/abdominal pain
following oocyte retrieval.

Relationship between serum antisperm antibodies
and anticardiolipin antibodies and clinical pregnancy
outcome in an in vitro fertilization and embryo transfer
program. Tian X, Zhang L, Wu Y, Yang C, Liu P.
Department of Obstetrics and Gynecology, Third
Clinical Medical School, Beijing Medical University,
Beijing 100083, China.
OBJECTIVE: To study the influence of maternal immunological
factors on clinical pregnancy outcome in an in vitro
fertilization and embryo transfer (IVF-ET) program.
METHODS: One hundred and fifty IVF-ET treatment cycles
from November 1995 to November 1996 were studied.
The indication for IVF-ET treatment was bilateral
blocked tubes. Serum antisperm antibodies and anticardiolipin
antibodies were measured using enzyme-linked immunosorbent
assay (ELISA). Cleavage rate and successful pregnancy
rate in relation to antibody status of infertile women
after IVF-ET treatment were assessed. RESULTS: Lower
cleavage rate (64.2% +/- 32.1%) was found in 44 cycles
of antisperm antibody seropositive women, compared
with 84.8% +/- 18.7% in 106 cycles of seronegative
women (P < 0.05). The clinical pregnancy rate was
31.8% in antisperm antibody-positive cycles and 20.8%
in negative cycles (P > 0.05). The abortion rates
of the two groups were similar (P > 0.05). Lower pregnancy
rate (9.5%) was found in 21 cycles of serum anticardiolipin
antibody-positive group, compared with 26.3% in 129
cycles of seronegative women (P < 0.05). Of patients
with bio-chemical pregnancy and no pregnancy, 20.0%
and 16.2%, respectively, had seropositive anticardiolipin
antibody, compared with 5.6% of patients with clinical
pregnancy (P < 0.05). CONCLUSION: Serum immunological
factors may play a part in clinical pregnancy outcome
in IVF-ET.

Embryo transfer after autologous endometrial coculture
improves pregnancy rates. Seta M.
Since the first in-vitro fertilization (IVF) baby
born in 1978, the technique of in-vitro fertilization-embryo
transfer (IVF-ET) has been well established and widely
used by clinicians all over the world. However, the
success rate of IVF-ET still remains relatively low.
Sub-optimal embryo culture condition may consider
as a factor contribute to the poor success rate. Autologous
endometrial coculture is a newly developed technique
able to enhance development of fertilized eggs using
the patient's own endometrial cells. A clinical tryout
was conducted in our institute. Patients underwent
either classic IVF (n = 82) (i.e., control group)
or autologous endometrial coculture (n = 134) (i.e.,
coculture group). The clinical pregnancy rate (per
patient) was significantly higher in coculture group
(48.5%) than control group (24.3%). Patients were
further subgrouped according to their age. For each
subgroup, the clinical pregnancy rates were again
consistently higher and the miscarriage rates were
consistently lower in the coculture group than in
the control groups. Coculture also increased clinical
pregnancy rate of patients who failed IVF at least
twice from 0% to 26.6%. Our data confirmed that autologous
endometrial coculture is an effective method to improve
the success rate of IVF-ET. The evidence of improving
clinical pregnancy rates and reducing abortion rates
after coculture suggest that coculture indeed improved
success rates by improving embryo quality.

Cryopreservation of ovarian tissue: banking reproductive
potential for the future. Lee D, Ouhibi N, Battaglia

Cryopreservation of ovarian tissue is a technology
that holds promise for banking reproductive potential
for the future. It may be apropos for cancer survivors
who have undergone treatment with sterility-inducing
chemotherapy. Although there is some evidence suggesting
cellular and molecular injury with the freezing and
thawing process, there are examples in both animals
and humans that transplantation of cryopreserved ovarian
tissue can effectively bank reproductive potential
for the future. This technology may ultimately have
applications for in vitro fertilization, and preventing
natural or iatrogenic menopause.

Poor responders: does the protocol make a difference?
Mahutte NG, Arici A.
Department of Obstetrics and Gynecology, Yale
University, New Haven, Connecticut 06520-8063, USA.
An inadequate response to gonadotropins during in-vitro
fertilization treatment may result in cycle cancellation,
fewer embryos available for transfer and decreased
pregnancy rates. For these reasons, numerous strategies
to improve ovarian stimulation in poor responders
have been proposed. These include variations in the
type, dose and timing of gonadotropins, gonadotropin-releasing
hormone agonists and gonadotropin-releasing hormone
antagonists. Unfortunately, despite optimism generated
by studies using retrospective controls, epidemiologically
sound trials have been scarce. Indeed, of the three
prospective randomized trials performed in poor responders
to date no compelling advantage for one stimulation
protocol over another has been established. Although
this lack of improvement may reflect inadequate sample
sizes, an alternative explanation is simply that the
protocol, after a certain point, does not make a difference.
Aside from oocyte donation, greater hope for poor
responders may rest in aneuploidy screening, in-vitro
oocyte maturation and cytoplasm/nuclear transfer.

OBJECTIVES: To investigate the variation of endometrial
responsiveness between cycles within the same women
undergoing assisted reproduction. METHODS: The sonographic
endometrial thickness in ovarian stimulation cycles
was compared with that of subsequent natural cycles.
One hundred and thirty-six ovarian stimulation cycles
of in-vitro fertilization and embryo transfer were
evaluated. Women who did not conceive in in-vitro
fertilization cycles were subsequently seen in natural
cycles (n = 97) or the next in-vitro fertilization
cycle (n = 39). Based on a receiver-operating characteristics
(ROC) curve using endometrial thickness to predict
pregnancy, the first in-vitro fertilization cycles
were classified according to the endometrial thickness
as optimal (> 8 mm) in 98 cycles, or suboptimal (<
or = 8 mm) in 29 cycles. Similarly, spontaneous cycles
were classified as suboptimal (< or = 7 mm) in 28
cycles and optimal (> 7 mm) in 69 cycles. RESULTS:
The pregnancy rates were significantly lower (P <
0.05; Fisher's Exact test) in the suboptimal group
in both the in-vitro fertilization and frozen embryo
transfer cycles. There was a strong correlation (r2
= 0.745) and a significant difference (P < 0.001;
Wilcoxon signed rank sum test) between the endometrial
thickness of stimulation and natural cycles. CONCLUSION:
It is possible to predict the occurrence of optimal
or suboptimal endometrial response in natural cycles
of women, after evaluation in stimulated cycles, with
a high degree of reliability. Risk of implantation
failure can be identified before subsequent treatment
cycles and adjuvant therapeutic strategies may be
planned to improve the endometrial response before
embryo transfer.

Fluid accumulation within the uterine cavity reduces
pregnancy rates in women undergoing IVF. Chien LW,
Au HK, Xiao J, Tzeng CR.
Department of Obstetrics and Gynaecology, Taipei
Medical University Hospital, Taipei, Taiwan.
BACKGROUND: The occurrence of fluid accumulation within
the uterine cavity was examined in women undergoing
IVF to investigate its correlation with tubal disease
and impact on the pregnancy outcome. METHODS: A registry
of ultrasound procedures spanning 5 years was retrospectively
studied. RESULTS: Thirty five out of 746 (4.7%) IVF
cycles were identified as having uterine fluid accumulation,
and 15 (2.0%) persisted until the day of embryo transfer.
Two of the 20 cycles of women with transient fluid
accumulation were pregnant, and none of those with
fluid retention on the day of embryo transfer conceived.
The pregnancy rate was only 5.7% (2/35) in women with
uterine fluid accumulation detected during IVF cycles.
In contrast, the pregnancy rate was 27.1% (193/711)
among women in whose cycles no fluid accumulation
was detected (P = 0.0048). Uterine fluid accumulation
during IVF cycles was found in 8% (18/225) of women
documented with tubal factor compared with 3.3% (17/521)
with non-tubal factor (P = 0.005). CONCLUSIONS: Fluid
accumulation within the uterine cavity during the
IVF transfer treatment could be observed in patients
with both tubal and non-tubal factors; however, it
mainly occurred in women with tubal infertility. Although
it is not a common complication of IVF cycles, excessive
uterine fluid is detrimental to embryo implantation.

The development of an oocyte-containing follicle
during gonadotrophin-releasing hormone agonist administration.
Almagor M, Hovav Y.
IVF and Fertility Laboratory, Department of Obstetrics
and Gynecology, Bikur Cholim Hospital, 5 Strauss St.,
Jerusalem 91004, Israel. almagors@hotmail.com Administration
of gonadotrophin-releasing hormone (GnRH) agonist
in a 29 year old woman with infertility due to ovulatory
dysfunction resulted in the development of several
ovarian cysts. After human chorionic gonadotrophin
(HCG) was injected, the cysts were aspirated and one
mature oocyte was retrieved. Intracytoplasmic sperm
injection (ICSI) was performed and the resulting embryo
was transferred. A singleton pregnancy was obtained
and a healthy baby was born at 36 weeks of gestation.
Because GnRH agonist-derived cysts may contain oocytes,
we suggest that when the growth of cysts is accompanied
by high concentrations of oestradiol, the administration
of HCG may be useful to achieve oocyte maturation
and advance IVF treatment.

Laparoscopic Fertility-Promoting Procedures of
the fallopian tube and the uterus. Sammour A, Tulandi
T.
Department of Obstetrics and Gynecology, McGill
University, Montreal, Quebec, Canada. Assisted reproductive
technology and reproductive surgery can be complementary,
and the feasibility of laparoscopic suturing has facilitated
conducting reproductive surgery entirely by laparoscopy.
Young women with tubal disease can be offered surgery,
whereas older women, with their rapid decline in fertility,
are better treated with in vitro fertilization (IVF).
IVF should be the first line of treatment for women
with a severe degree of hydrosalpinx, or with extensive
and dense adhesions. However, the presence of hydrosalpinx
decreases IVF pregnancy rates. In those whose hydrosalpinx
is seen on ultrasound, especially after failed IVF
cycles, a laparoscopic salpingectomy can be done.
For tubal anastomosis, the superior results of this
procedure are well established. The association between
uterine myoma and infertility is unclear. However,
in those with a distorted uterine cavity, and no other
cause of infertility, myomectomy can be considered;
myomectomy can be done by laparoscopy. Because of
the risks of uterine rupture, proper closure of the
uterine incision is of utmost importance.

Ultrasound Unit, Department of Obstetrics and
Gynecology, Rabin Medical Center, Petah Tikva, Israel.
OBJECTIVE: To evaluate the use of transvaginal sonography
for the detection of pelvic adhesions by using clear
free fluid in the pouch of Douglas found after ovum
pickup. METHODS: A prospective clinical study was
performed in an infertility unit of an academic research
facility. Sonography was performed in 50 women with
infertility 3 days after ovum pickup, and the visceral
peritoneum of the uterus, the ovaries, and the fallopian
tubes was scanned for possible pelvic adhesions. RESULTS:
The serosal surfaces of the uterus, ovaries, and fallopian
tubes were successfully observed for the presence
of adhesions in 86%, 68%, and 20% of the patients,
respectively. Improved visualization was associated
with an increased amount of pelvic fluid for the uterus
(P = .01) but not for the ovaries and fallopian tubes.
The amount of fluid in the pelvis correlated with
an increased number of retrieved oocytes (P = .07)
and a decreased need for manual manipulation to achieve
proper imaging of the uterus (P = .001). CONCLUSION:
Transvaginal sonography performed in the presence
of fluid in the pelvis may show adhesions mainly attached
to the uterus and ovaries. Assessment of possible
mechanical factors is important in planning treatment
of patients with infertility.

Department of Obstetrics and Gynecology, Taipei
Medical University and Hospital, Taipei, Taiwan.
OBJECTIVE: To investigate the correlation of blood
flow detected by color Doppler sonography in the endometrial-subendometrial
unit with pregnancy outcome of IVF-ET treatments.
DESIGN: Prospective clinical study. SETTING: University
setting. PATIENT(S): Six hundred twenty-three patients
selected prospectively on the day of ET. INTERVENTION(S):
Transvaginal ultrasound examination was performed
before ET. MAIN OUTCOME MEASURE(S): Association between
pregnancy outcome and distribution of endometrial-subendometrial
blood flow (primary outcome measure) and between pregnancy
rate and endometrial measurements as well as uterine
arterial blood flow (secondary outcome measures).
RESULT(S): The overall pregnancy rate was 28.4% (177/623)
per ET. The pregnancy and implantation rates of patients
with the presence of both endometrial and subendometrial
flow were 47.8% (64/134) and 24.2% (94/388); for patients
with subendometrial flow only, 29.7% (102/343) and
15.8% (153/967); and for patients with no detectable
endometrial-subendometrial flow, 7.5% (11/146) and
3.5% (13/376), respectively. The presence of both
endometrial and subendometrial blood flow is indicative
of good endometrial receptivity, whereas the absence
of both represents a poor uterine environment. Nondetectable
endometrial-subendometrial flow was associated with
women who were older, had a thinner endometrium, and
had higher uterine arterial resistance compared with
those women who had detectable flow. CONCLUSION(S):
Endometrial-subendometrial blood flow distribution
pattern assessed by transvaginal color Doppler before
ET is correlated with the implantation and pregnancy
rate of IVF treatment.

Spain.
BACKGROUND: Recent randomized controlled trials have
shown that implantation and pregnancy rates were improved
with ultrasound-guided embryo transfer compared with
clinical touch in fresh IVF cycles associated with
supraphysiological ovarian steroid levels. However,
the usefulness of ultrasound guidance in frozen-thawed
embryo transfer where potential hormonal influences
are lacking has not been appropriately investigated.
METHODS: A total of 184 consecutive patients undergoing
thawed embryo transfer cycles with hormone replacement
under pituitary suppression were randomized by computer-generated
randomization table to two study groups: 93 had ultrasound-guided
(group 1) and 91 had clinical touch (group 2) embryo
transfer. RESULTS: There was equal distribution between
the two study groups with respect to the main demographic
and baseline characteristics of the patients as well
as the characteristics of both prior IVF cycles from
which embryos were generated and cryopreserved-thawed
embryo transfer cycles. However, both pregnancy and
implantation rates in group 1 (34.4 and 19.8% respectively)
were significantly higher than the corresponding values
(19.7 and 11.9%) in group 2. CONCLUSIONS: Ultrasound
guidance in frozen-thawed embryo transfer significantly
increases pregnancy and implantation rates.

OBJECTIVE: To explore the relevance of the embryo
morphology with the clinical result of intracytoplasmic

METHODS: A retrospective analysis was conducted of
291 ISCI and 352 in vitro fertility (IVF) cycles collected
during the period from January, 1999 to March, 2001.
RESULTS: Significant difference was not found in the
fertility rates between the 2 groups (75.7% vs 73.2%,
P=0.5738), nor in the oocyte lysis rates (10.6% vs
7.9%, P=0.238). The rates of the embryos with more
than 20% fragments were similar between the 2 groups
(41.2% vs 55.8%, P=0.137), but ICSI group had a significantly
lower rate of blastocyst formation (43.1% vs 55.8%,
P<0.001). The clinical pregnancy rates and miscarriage
rates did not vary significantly between the 2 groups
(34.7% vs 39.9%, P=0.189; 8.9% vs 13.4%, P=0.079).
CONCLUSIONS: ISCI is an effective treatment for male
infertility to achieve uneventful clinical pregnancy.

IVF.DESIGN: Retrospective, controlled study.SETTING:
University center.PATIENT(S): Fifty-five patients
undergoing IVF using a minimal-stimulation protocol
with or without adjuvant therapy with a GnRH antagonist.
A control group consisted of age- and diagnosis-matched
patients undergoing a standard long GnRH agonist (GnRH-a)-gonadotropin
stimulation during the same time period.INTERVENTION(S):
Clomiphene citrate and gonadotropins, with or without
the GnRH antagonist ganirelix.MAIN OUTCOME MEASURE(S):
Oocytes recovered and pregnancy rates.RESULT(S): The
number of oocytes retrieved was significantly lower
for the minimal-stimulation regimen compared with
the case of the long GnRH-a protocol (4.8 +/- 2.6
vs. 16.2 +/- 7.5, respectively). The clinical pregnancy
rate per transfer, however, was not significantly
different between the two regimens (37% vs. 41%, minimal
stimulation vs. long GnRH-a protocol, respectively).
The addition of ganirelix resulted in at least the
same pregnancy outcome as compared with the case of
cycles without the antagonis
CONCLUSION(S): Minimal stimulation using clomiphene
citrate followed by gonadotropin for IVF results in
pregnancy rates equal to the standard long GnRH-a-gonadotropin
protocol. The addition of ganirelix resulted in at
least similar results with the advantage of eliminating
the occurrence of a premature endogenous LH surge.

Interleukin-1beta expression on ovarian granulosa
cells and its clinical implication in women undergoing
in vitro fertilization. Wang XF, Xing FQ, Chen SL.
Department of Obstetrics and Gynecology, Nanfang
Hospital, First Military Medical University, Guangzhou
510515, China.
OBJECTIVE: To detect the expression of interleukin-1beta
(IL-1beta) on the surface of human luteinized granulosa
cells and to understand its relation to the hormones
in human follicular fluid and sera.
METHODS: Thirty-six women receiving in vitro fertilization-embryo
transfer (IVF-ET) were enrolled in this study. The
luteinizing granulosa cells were recovered from the
follicular fluid obtained during transvaginal ultrasound-guided
oocyte retrieval for IVF-ET. Flow cytometry was employed
to detect the expression of IL-1beta on human granulosa
cells, and the concentrations of IL-1beta and the
hormones in the follicular fluid were measured by
enzyme-linked immunosorbent assay. RESULTS: IL-1beta
was detected in the follicular fluid of women with
IVT-ET and in the luteinizing granulosa cells. A positive
correlation was observed between the sera concentrations
of IL-1beta and estradiol on the day when human chorionic
gonadotrophin (hCG) was injected (r=0.92, P<0.001),
while on the same day the concentration of IL-1beta
was shown to be inversely correlated with progesterone
levels (r=-0.34, P<0.05). CONCLUSION: IL-1beta in
the follicular fluid comes not only from plasma ultrafiltrate
but also from luteinizing granulosa cells. The inhibition
of progesterone production by luteal cells in the
presence of IL-1beta may be one of the factors resulting
in the failure of implantation.

no differences in all the parameters studied (E(2)
levels, number of follicles, oocytes retrieved, number
and quality of embryos transferred, and clinical pregnancy
rate) except for the number of gonadotropin ampoules
needed for ovarian hyperstimulation, which was significantly
higher in group A than in group B. CONCLUSION(S):
Our results indicate that laparoscopic cystectomy
for endometriomas is an appropriate treatment since
it did not negatively affect the ovarian response
for IVF-ET.

Increased pregnancy rates after ultralong postoperative
therapy with gonadotropin-releasing hormone analogs
in patients with endometriosis.
Rickes D, Nickel I, Kropf S, Kleinstein J.
Clinic for Reproductive Medicine and Gynecologic
Endocrinology, Faculty of Medicine, Otto-von-Guericke
University, Magdeburg, Germany OBJECTIVE: To examine
whether ultralong GnRH analog (GnRH-a) therapy after
surgical treatment of endometriosis and before ART
influences the pregnancy rate.DESIGN: Prospective,
randomized, controlled study.SETTING: University clinic
for reproductive medicine and gynecologic endocrinology.PATIENT(S):
One hundred ten patients with stage II to IV endometriosis
according to ASRM criteria.INTERVENTION(S): Fifty-five
patients received GnRH-a for 6 months after surgery
and subsequently underwent up to 3 cycles of ART,
and 55 patients received 3 cycles of ART alone immediately
after surgery.MAIN OUTCOME MEASURE(S): Clinical pregnancy
rates.RESULTS: The pregnancy rate per patient was
higher among patients who received follow-up treatment
with GnRH-a. The same results were found in patients
with stage III or IV endometriosis who were undergoing
IUI or IVF/ICSI.CONCLUSION(S): Ultralong GnRH-a therapy
increases the pregnancy rate of ART in patients with
severe endometriosis.

Predictive power of clomiphene citrate challenge
test for failure of in vitro fertilization treatment.
Csemiczky G, Harlin J, Fried G.
BACKGROUND: To evaluate the impact of ovarian
reserve on the outcome of in vitro fertilization (IVF)
treatment in 140 women, in a total of 279 treatment
cycles. METHODS: All women underwent a clomiphene
citrate (CC) challenge test to assess their ovarian
reserve before IVF treatment. One hundred and eighteen
women (84%) had normal basal follicle stimulating
hormone (FSH) levels (3.1-10.0 IU/l) and 22 women
(16%) had elevated FSH levels (> 10.0-24.0 IU/l).
The FSH levels measured on cycle day 10 showed that
106 (76%) of the women could be regarded as having
a normal ovarian reserve and 34 (24%) a diminished
ovarian reserve. CONCLUSIONS: We found that the CC
challenge test is a useful tool in assessing a woman's
ovarian capacity before infertility treatment. The
predictive value of the test for a negative outcome
of IVF treatment was strong. We recommend performing
the test before infertility treatment. This may prevent
unnecessary treatment trials and unrealistic expectations
from both patients and doctors.

Health, Centre for Clinical Decision Sciences, Erasmus
Medical Centre, Rotterdam, The Netherlands. BACKGROUND:
Extending the period of in-vitro culture to the blastocyst
stage may improve implantation rates in IVF treatment.
Recognition of the dynamic nature of early embryo
metabolism has led to the development of commercially
available sequential culture systems. However, their
improved efficacy over monoculture systems remains
to be demonstrated in prospective studies. METHODS:
Embryos obtained from 158 women undergoing IVF treatment
were randomized by sealed envelopes to culture in
one of three systems: (A) culture for 5 days in our
own monoculture medium (Rotterdam medium); (B) culture
for 3 days in Rotterdam medium followed by 2 days
in fresh Rotterdam medium; (C) culture for 5 days
using the commercially available G1/G2 sequential
culture system. RESULTS: There were no significant
differences in blastulation, implantation or pregnancy
rates between the three tested culture systems. CONCLUSION:
The employed monoculture system is as effective as
the G1/G2 sequential system for the culture of blastocysts
for IVF.

Continuation of GnRH agonist administration for
1 week, after hCG injection, prevents ovarian hyperstimulation
syndrome following elective cryopreservation of all
pronucleate embryos. Endo T, Honnma H, Hayashi T,

H, Kudo R.
Department of Obstetrics and Gynecology, Sapporo
Medical University School of Medicine, Department
of Obstetrics and Gynecology, Tonan Hospital and Kamiya
Lady's Clinic, Sapporo, Japan. BACKGROUND: An approach
consisting of elective cryopreservation of all embryos
has been proposed for patients at risk of ovarian
hyperstimulation syndrome (OHSS). Although elective
cryopreservation can prevent pregnancy-induced late
OHSS, it cannot prevent early OHSS. Early OHSS is
reported to have been complicated with thromboembolism.
The study was carried out to assess the efficacy with
which the continued administration of GnRH agonist
for 1 week after 5000 IU of hCG injection could prevent
early OHSS. METHODS: This study employed an open controlled
clinical trial at three centres for treatment of infertility
in Sapporo. A total of 138 patients at risk of OHSS
during IVF-embryo transfer from January 1, 1998 to
December 31, 1999, were assigned in turn either to
a group with elective cryopreservation of all pronucleate
embryos (n = 68) or to one with continuation of GnRH
agonist administration for 1 week after hCG injection
following elective cryopreservation (n = 70). Subsequently,
they were transferred in hormone replacement cycles.
The development of severe OHSS (ascites, haemoconcentration)
was compared between the two groups. RESULTS: A total
of 10% of patients developed severe OHSS necessitating
hospitalization because of a marked increase in ascites
in the upper abdomen and the haemoconcentration in
the elective cryopreservation alone group. On the
other hand, none developed severe OHSS in the GnRH
agonist continuation group. CONCLUSIONS: In our study,
continuation of GnRH agonist for 1 week after hCG
injection prevented severe early OHSS following elective
cryopreservation of all embryos. This treatment is
safe and cost-beneficial, and should be performed
promptly for patients at risk of OHSS.

IVF and tubal pathology--not all bad news.
Johnson NP, Sadler L, Merrilees M.
University Division of Obstetrics and Gynaecology,
National Women's Hospital, Auckland, New Zealand.
OBJECTIVES: In light of evidence that hydrosalpinges
compromise the chance of success of in vitro fertilisation
(IVF), the aim of this study was to analyse the results
of IVF treatment at our clinic in relation to the
cause for infertility and to make inferences concerning
the impact of mild tubal disease on IVF outcome. CONCLUSION:
The overall population of women with tubal disease
as the sole cause for infertility (including women
with hydrosalpinges and those with non-hydrosalpinx
tubal disease) does not have an overall reduced likelihood
of success at IVF. This suggests that non-hydrosalpinx
tubal disease does not compromise the chance of success
from IVF. Surgical treatment prior to IVF for the
milder forms of tubal disease is not warranted.

OBJECTIVE: To determine whether administration of
methylprednisolone to high-risk women undergoing IVF/ICSI
helps reduce the development of OHSS.DESIGN: Retrospective
clinical controlled study.SETTING: IVF unit.PATIENT(S):
One thousand ten women who underwent IVF/ICSI from
January 9, 1997, to December 31, 1999. Ninety-one
patients who were at high risk for OHSS were identified
by using standard criteria.INTERVENTION(S): Methylprednisolone,
16 mg/d starting on day 6 of the stimulation and tapered
after the first pregnancy test (day 13 after embryo
transfer).MAIN OUTCOME MEASURE(S): Occurrence of OHSS.RESULT(S):
A significantly lower proportion of methylprednisolone
recipients than untreated participants developed OHSS
(10.0% vs. 43.9%). Treatment recipients had more oocytes
retrieved and more embryos fertilized than did untreated
participants. Methylprednisolone treatment was equally
effective in preventing OHSS in all causes of infertility
and was effective independent of the number of IVF
trials and pregnancy rates.CONCLUSION(S): Treatment
with methylprednisolone appears to reduce the risk
for OHSS. This treatment thus helps to avoid hospitalization,

Efficacy and safety of highly purified menotropin
versus recombinant follicle-stimulating hormone in
in vitro fertilization/intracytoplasmic sperm injection
cycles: a randomized, comparative trial. The European
and Israeli Study Group on Highly Purified Menotropin
versus Recombinant Follicle-Stimulating Hormone.
Kiel, Augsburg, Germany.
OBJECTIVE: To demonstrate that highly purified human
menopausal gonadotropin (HP-hMG) is as efficient and
safe as recombinant FSH in females undergoing in vitro
fertilization/intracytoplasmic sperm injection (IVF/ICSI)
treatment cycles.DESIGN: Multinational, open label,
randomized, parallel group, comparative phase III
trial.SETTING: In 22 centers across six countries;
Belgium (1 center), Germany (6 centers), Israel (6
centers), The Netherlands (2 centers), Switzerland
(1 center) and the United Kingdom (6 centers).PATIENT(S):
A total of 781 women were enrolled between May 1999
and November 2000.INTERVENTION(S): In the all-patients-treated
population, 373 patients received HP-hMG and 354 received
recombinant FSH. A long protocol GnRH agonist regimen
was used.MAIN OUTCOME MEASURE(S): The primary end
point was ongoing pregnancy rate following one IVF/ICSI
treatment cycle. Safety was assessed as a secondary
end point.RESULT(S): Ongoing pregnancy rates 10 weeks
after ovum pickup in the per-protocol population were
25% (n = 85/344) in the HP-hMG group and 22% (n =
71/317) in the recombinant FSH group. The incidence
of ovarian hyperstimulation syndrome, miscarriage,
adverse events, and injection site reactions (tolerability)
were similar in both treatment groups.CONCLUSION(S):
We found HP-hMG to be as effective as recombinant
FSH in terms of ongoing clinical pregnancy. Both treatments
have a similar safety/tolerability profile.

of Melbourne, Australia. kuleshova@ivf.co.jp
OBJECTIVE: Cryopreservation of embryos and oocytes
has become an essential service for infertility treatment.
The clinical application of this technology should
ensure optimal survival of the embryos and oocytes
that are stored and subsequently thawed for transfer.
The aim of this review is to compare the widely employed
slow cooling procedures with vitrification to evaluate
and recommend the more effective and safer procedure.DESIGN:
The review is mainly based on a comparison of the
principles, procedures, and results reported in the
literature. A historical description of vitrification
and personal experiences with this technology are
also included. MAIN OUTCOME MEASURE(S): Reported number
of pregnancies established after transfer of embryos
that were cryopreserved by vitrification, or transfer
of embryos derived from vitrified oocytes.RESULT(S):
Both slow cooling and vitrification procedures have
resulted in the successful cryopreservation of human
embryos and oocytes. Both procedures have resulted
in healthy births, although the slow cooling of oocytes
gives very low success rates. Vitrification is a promising
novel technique in assisted reproductive technology,
but comparative success rates are yet to be established.CONCLUSION(S):
Vitrification is a simple procedure that requires
less time and is likely to become safer and more cost
effective than slow cooling.

Comparison between a single dose of goserelin (depot)
and multiple daily doses of leuprolide acetate for
pituitary suppression in IVF treatment: a clinical
endocrinological study of the ovarian response.
Geber S, Sales L, Sampaio MA.
ORIGEN, Centro de Medicina Reprodutiva, Belo Horizonte,
Minas Gerais, Brazil. sjgeber@bhnet.com.br PURPOSE:
Compare the efficacy and safety of two different GnRHa,
used for pituitary suppression in IVF cycles. METHODS:
A total of 292 patients using depot goserelin (Group
1) and 167 using daily leuprolide acetate (Group 2)
were compared. Days required to achieve pituitary
function suppression, duration of ovarian stimulation,
total dose of HMG, number of aspirated follicles,
number of oocytes retrieved, and presence of functional
ovarian cyst were analyzed. RESULTS: The time taken
to achieve downregulation was similar. The mean number
of ampoules used for superovulation was higher in
Group 1; however, this difference was observed only
for patients >40 years old that started GnRHa in the
follicular phase. There was no difference between
the two groups in the duration of superovulation,
in the number of follicles aspirated, and the number
of oocytes retrieved. In the group of patients with
>40 years the incidence of ovarian cysts was higher
in Group 2. CONCLUSIONS: Both routes of GnRHa have
similar effects for pituitary suppression and ovulation
induction in assisted reproductive technology. Therefore
the long-acting GnRHa is an excellent option, as only
a single subcutaneous dose is necessary, decreasing
the risk of the patient to forget its use and, most
important, it does not interfere in the patient's
quality of life.

PURPOSE: To evaluate the effect of autologous
endometrial coculture in patients (less than 36 years
old) with a history of a single IVF failed cycle associated
with poor quality embryos. METHODS: Design: Controlled
clinical study. Setting: University-based in vitro
fertilization center. Patients: Twenty-six patients
with a history of a single prior failed IVF-ET with
poor preembryo quality. Intervention(s): Autologous
endometrial coculture. Main outcome measures: Preembryo
blastomere numbers and cytoplasmic fragmentation rates
were compared between the treatment and previous cycle.
Clinical pregnancy rates were analyzed. RESULTS: Twenty-six
women with an average age of 32.8 +/- 2.9 years underwent
treatment. On Day 3 the overall mean number of blastomeres
per preembryo on coculture compared to conventional
medium in a previous cycle was 6.1 +/- 1.8 vs. 5.1
+/- 1.3 (P = 0.01; Wilcoxon test). The average percentage
of cytoplasmic fragments on coculture compared to
the conventional medium in a previous cycle was 14%
+/- 10 vs. 22% +/- 13 (P = 0.003; Wilcoxon test).
At transfer the mean number of blastomeres per preembryo
on coculture was 7.4 +/- 1.8 compared to 6.7 +/- 1.5
on conventional medium in a previous cycle (P = 0.02;
Wilcoxon test). The clinical pregnancy rate (positive
fetal cardiac activity) per patient was 88.5%. The
delivery rate was 73.1% (19/26). CONCLUSIONS: There
was an improvement in the preembryo quality for preembryos
on autologous endometrial coculture compared to noncocultured
preembryos from the same patient in a previous cycle.
An excellent delivery rate was subsequently found.

20, 5340 BH, Oss, The Netherlands. BACKGROUND: To
establish long-term safety, follow-up data on pregnancy,
birth and neonatal outcome were collected during clinical
development trials with ganirelix (Orgalutran) in
women undergoing controlled ovarian stimulation for
conventional IVF or ICSI. METHODS: Results of an analysis
of the pooled data of all follow-up data of the phase
2 and 3 programme for the development of ganirelix
are presented. Obstetrical data on 340 ongoing pregnancies
( vertical line16 gestational weeks) after ganirelix
treatment and 134 pregnancies after GnRH agonist treatment
in a long protocol are shown. Furthermore, the neonatal
outcome of 432 children [258 (75.9%) singletons, 72
(21.2%) twins and 10 (2.9%) triplets] born in the
ganirelix group is presented and compared with 184
children [91 (67.9%) singletons, 36 (26.9%) twins
and seven (5.2%) triplets] in the agonist group. CONCLUSIONS:
Reviewing the presented data and the literature on
obstetric and neonatal outcome after conventional
IVF or ICSI, we conclude that a controlled ovarian
stimulation protocol including the novel GnRH antagonist
ganirelix has been shown to be safe for pregnant women
and their newborn babies.

University Clinic, Ratzeburger Allee 160, 23538 Lubeck,
Germany.
BACKGROUND: With the recently introduced GnRH
antagonists, soft stimulation protocols on the basis
of clomiphene pretreatment should be possible as the
pituitary remains fully sensitive at the beginning
of the cycle. METHODS: A prospective trial was carried
out on 107 patients undergoing IVF treatment using
the multiple dose GnRH antagonist protocol (cetrorelix),
clomiphene citrate, and either HMG (n = 54) or recombinant
FSH (rFSH) (n = 53). Different stimulation protocols
were used to find the most appropriate one for clinical
application. RESULTS: Both treatment groups, HMG and
rFSH, yielded comparable results concerning gonadotrophin
dose, stimulation days and pregnancy rate. A mean
number of 6.34 +/- 4.4 metaphase II oocytes was retrieved
and a mean number of 2.45 +/- 0.65 embryos was transferred.
However, the overall rate of premature LH surges was
21.5% (defined as measurement of LH >10 IU/l and progesterone
>1 ng/ml) which is unacceptable for clinical practice.
CONCLUSIONS: Increasing the daily cetrorelix dose
from 0.25 to 0.5 mg might decrease the number of premature
LH surges. Soft stimulation protocols with clomiphene
should be used cautiously.

Department of Obstetrics and Gynecology, Taipei
Medical University and Hospital, Taipei, Taiwan. OBJECTIVE:
To investigate the correlation of blood flow detected
by color Doppler sonography in the endometrial-subendometrial
unit with pregnancy outcome of IVF-ET treatments.
DESIGN: Prospective clinical study. SETTING: University
setting. PATIENT(S): Six hundred twenty-three patients
selected prospectively on the day of ET. INTERVENTION(S):
Transvaginal ultrasound examination was performed
before ET. MAIN OUTCOME MEASURE(S): Association between
pregnancy outcome and distribution of endometrial-subendometrial
blood flow (primary outcome measure) and between pregnancy
rate and endometrial measurements as well as uterine
arterial blood flow (secondary outcome measures).
RESULT(S): The overall pregnancy rate was 28.4% (177/623)
per ET. The pregnancy and implantation rates of patients
with the presence of both endometrial and subendometrial
flow were 47.8% (64/134) and 24.2% (94/388); for patients
with subendometrial flow only, 29.7% (102/343) and
15.8% (153/967); and for patients with no detectable
endometrial-subendometrial flow, 7.5% (11/146) and
3.5% (13/376), respectively. The presence of both
endometrial and subendometrial blood flow is indicative
of good endometrial receptivity, whereas the absence
of both represents a poor uterine environment. Nondetectable
endometrial-subendometrial flow was associated with
women who were older, had a thinner endometrium, and
had higher uterine arterial resistance compared with
those women who had detectable flow. CONCLUSION(S):
Endometrial-subendometrial blood flow distribution
pattern assessed by transvaginal color Doppler before
ET is correlated with the implantation and pregnancy
rate of IVF treatment.

Endometrial aspiration biopsies: in stimulated cycles
on the day of oocyte retrieval within the ET cycle
(Day OPU) (n = 20) or 2 days later (Day OPU + 2) (n
= 7); in natural cycles on the natural day of ovulation
(Day NO) (n = 10) or on the day of ovulation + 2 (Day
NO + 2) (n = 10). MAIN OUTCOME MEASURE(S): Comparison
of endometrial maturation, estrogen (ER) and P receptor
(PR), and proliferation index by immunohistochemistry
in natural and stimulated cycles, correlation with
pregnancy outcome in stimulated cycles. RESULT(S):
Stimulated cycles Day OPU showed significantly advanced
endometrial maturation compared to natural cycles
Day NO; stromal ER and glandular and stromal PR staining
was lower in stimulated than in natural cycles, but
higher on Day OPU than on Day NO + 2; proliferation
index was lower in all stimulated cycles. Steroid
receptors and proliferation index in stimulated cycles
were unrelated to clinical pregnancy occurrence. CONCLUSION(S):
Compared to natural cycles, ovarian stimulation induced
an imbalance in endometrial ER and PR and led to a
profound antimitotic effect in the peri-ovulatory
phase. These parameters were, however, not predictive
of clinical pregnancy in cycles with ET.

University Central Hospital and Department of Obstetrics
and Gynaecology, South Karelia Central Hospital, Finland.
BACKGROUND: Assisted reproduction treatment (ART)
entails a risk of ectopic pregnancy and early pregnancy
loss. Serum HCG has been found to be predictive of
pregnancy outcome. Our aim was to assess the clinical
value of a single early HCG assay in ART pregnancies
taking into account the aetiology and treatment of
infertility. METHODS: During 1994-1999, we studied
774 embryo transfer cycles resulting in pregnancy
defined as a serum HCG concentration of vertical line5
IU/l on day 12 following embryo transfer. The treatment
included IVF in 518, ICSI in 119, and frozen embryo
transfer in 137 cycles. Serum HCG concentrations were
measured by fluoroimmunometric assay. Pregnancies
were classified as viable (live fetus at vertical
line22 weeks gestation) or non-viable (biochemical
pregnancy, miscarriage, ectopic pregnancy and molar
pregnancy). Data on the outcomes were retrospectively
retrieved from the records. CONCLUSIONS: A single
HCG reading on day 12 after embryo transfer helps
to plan the subsequent follow-up. Male factor infertility
and ICSI are associated with relatively low HCG values
in viable pregnancies.

BACKGROUND: Infertility itself and also assisted
reproductive treatment increase the incidence of some
obstetric complications. Women with unexplained infertility
are reported to be at an increased risk of intrauterine
growth restriction during pregnancy, but not for other
perinatal complications. METHODS: A matched case-control
study was performed on care during pregnancy and delivery,
obstetric complications and infant perinatal outcomes
of 107 women with unexplained infertility, with 118
clinical pregnancies after IVF or ICSI treatment.
These resulted in 90 deliveries; of these, 69 were
singleton, 20 twin and one triplet. Two control groups
were chosen from the Finnish Medical Birth Register,
one group for spontaneous pregnancies (including 445
women and 545 children), matched according to maternal
age, parity, year of birth, mother's residence and
number of children at birth, and the other group for
all pregnancies after IVF, ICSI or frozen embryo transfer
treatment (FET) during the study period (including
2377 women and 2853 children). CONCLUSIONS: The overall
obstetric outcome among couples with unexplained infertility
treated with IVF was good, with similar outcome compared
with spontaneous pregnancies and IVF pregnancies generally.

House, Guy's Hospital, St. Thomas' Street, SE1 9RT,.,
London, UK
OBJECTIVE: To evaluate the value of increasing
the gonadotrophin dose after 5 days of controlled
ovarian stimulation in IVF patients who show an initial
poor response to stimulation. SUBJECTS AND METHODS:
We identified all IVF cycles between January 1992
and March 1996 in which ovarian response after 5 days
of controlled ovarian hyperstimulation (COH) with
225-300IU per day of human menopausal gonadotrophins
(hMG; Metrodin or Pergonal) was monitored by measurement
of serum estradiol concentrations (n=596 patients).
According to estradiol concentration, the daily dose
of hMG was doubled or increased to 450IU in 193 patients
(group A) or maintained the same in 403 patients (group
B). Further cycle monitoring was achieved using serial
ultrasound and serum estradiol measurements. RESULTS:
The two groups were age-matched. Group A patients
experienced a higher cancellation rate despite having
a higher mean number of hMG ampoules (59.5 versus
36.2) and a longer duration of stimulation (12.2 versus
10.8 days). They achieved lower levels of serum estradiol
on days 9 and 10 of stimulation, produced a lower
mean number of oocytes per retrieval (5.8 versus 8.9)
and had a lower clinical pregnancy rate per cycle
(8.3 versus 23.4%) compared to group B. All differences
were statistically significant. CONCLUSION: The poor
outcome of cycles with initial low response to COH
appears not to be averted by doubling or increasing
the hMG dose after 5 days of stimulation.

The efficacy and safety of short acting buserelin
and nafarelin intranasal spray were compared to long
acting leuprorelin depot intramuscular or subcutaneous
injection in this prospective study of 157 women undergoing
controlled ovarian hyperstimulation (COH) for in-vitro

greater incidence of allergic nasal reactions in the
nafarelin group (P=0.001), all other side-effects
were not shown to be statistically significantly different
between the three groups. We conclude that a single
dose of leuprorelin depot can be considered to be
as an equally effective alternative to multiple doses
of buserelin or nafarelin for pituitary desensitisation
in women undergoing COH for IVF.

OBJECTIVE: To analyze the effectiveness of autologous
endometrial coculture by the cycle day of the endometrial
biopsy. DESIGN: Retrospective study. SETTING: University-based
IVF center. PATIENT(S): Two hundred eight patients
with multiple IVF failures. INTERVENTION(S): Embryos
were split and randomly allocated to growth on autologous
endometrial coculture or conventional media. MAIN
OUTCOME MEASURE(S): Embryo quality and pregnancy outcome.
RESULT(S): The overall clinical pregnancy rate was
41.8%. Embryos grown on autologous endometrial coculture
were of higher quality (more blastomeres and less
fragmentation) than embryos grown with conventional
media. Early luteal biopsies (<5 days after LH surge)
for autologous endometrial coculture did not demonstrate
an improvement in embryo quality as compared to the
significant improvement demonstrated with later luteal
endometrial biopsies (> or =5 days after LH surge).
The date of the biopsy was predictive of pregnancy
outcome when using autologous endometrial coculture
(44.7% [> or =5 days after LH surge] vs. 18.8% [<5
days after LH surge], P=.012). CONCLUSION(S): We have
demonstrated an improvement in embryo quality when
using autologous endometrial coculture. The improvement
in embryo quality and higher pregnancy rates were
limited to biopsies > or =5 days after the LH surge.
This suggests that mid/late luteal phase endometrium
contains factors that enhanced embryo growth and subsequent
implantation.

The Fertility Institute of New Orleans, New Orleans,
Louisiana, USA. OBJECTIVE: To compare the efficacy
and safety of Bravelle s.c., Bravelle i.m., and Follistim
s.c. in patients undergoing controlled ovarian hyperstimulation
for IVF-ET. DESIGN: Open-label, randomized, parallel
group, multicenter study. SETTING: Eleven academic
and private fertility clinics with experience in IVF-ET.
PATIENT(S): Infertile premenopausal women with regular
ovulatory menstrual cycles undergoing IVF-ET. INTERVENTION(S):
Down-regulation with leuprolide acetate followed by
up to 12 days of Bravelle s.c. (n = 60), Bravelle
i.m. (n = 59), or Follistim s.c. (n = 58); hCG administration,
oocyte retrieval, and ET. MAIN OUTCOME MEASURE(S):
Mean number of oocytes retrieved; patients with ET,
chemical, clinical and continuing pregnancies; mean
peak serum E2 levels; adverse events and injection
site pain scores. RESULT(S): There were no significant
differences among treatment groups in mean number
of oocytes retrieved, peak serum E2 levels, patients
with ET, continuing pregnancies, or live births. There
were no significant differences among the treatment
groups in the number, nature, or intensity of adverse
events. Patients treated with Bravelle s.c. or Bravelle
i.m. experienced significantly less injection site
pain than patients treated with Follistim s.c. CONCLUSION(S):
Bravelle s.c. and Bravelle i.m. are comparable in
efficacy and safety to Follistim s.c. in patients
undergoing controlled ovarian hyperstimulation for
IVF-ET.

BACKGROUND: Ovarian reserve significantly influences
IVF outcome. Low response to ovarian stimulation due
to reduction of ovarian reserve is occasionally encountered
in young women. The aim of this study was to evaluate
the outcome of IVF treatment in young patients with
reduced ovarian reserve. METHODS AND RESULTS: Between
January 1993-2001, 762 consecutive patients satisfied
the definition of reduced ovarian reserve (raised
early follicular phase FSH or gonadotrophin stimulation
cycles where three or fewer oocytes were retrieved
after routine FSH stimulation) and were included in
the study. They were classified into three age groups:
young (=30 years), intermediate (31-38 years) and
older (>38 years). The three age groups were similar
with respect to basal (day 3) serum FSH and estradiol
concentrations, cause of infertility and number of
previous treatment cycles. Implantation (13, 9.6 and
9.8%), clinical pregnancy (11.8, 10.2 and 10%) and
live birth (7.4, 7.3 and 6.8%) rates were not significantly
different in the three age groups respectively (P
> 0.05). CONCLUSION: This study shows that younger
patients with reduced ovarian reserve have a poor
outcome of IVF treatment similar to their older counterparts.
Such information may be helpful in counselling these
patients who otherwise might anticipate an outcome
related to their chronological age.

A prospective randomized study: day 2 versus day
5 embryo transfer. Van Der Auwera I, Debrock S, Spiessens

Hospital Gasthuisberg, Catholic University Leuven,

BACKGROUND: This randomized controlled study was performed
in an unselected IVF/ICSI population to test the hypothesis
that blastocyst transfers result in higher clinical
pregnancy rates (CPR) per oocyte retrieval when compared
with day 2 transfers. METHODS: Blind randomization
for transfer on day 2 (group 1) or day 5/6 (group
2) was performed before stimulation. Oocytes and embryos
were cultured in sequential media in 5.5% CO(2), 5%
O(2), 89.5% N(2) and 90% humidity. A maximum of two
embryos was transferred. RESULTS: The two groups were
similar for age, IVF indication, number of treatment
cycles, rate of ICSI/IVF, number of fertilized oocytes
and number of embryos transferred. The CPR/oocyte
retrieval was comparable in group 1 (32%) and in group
2 (44%), while the CPR/embryo transfer was significantly
higher (P < 0.01) in group 2 (60%) than in group 1
(35%). Similarly, the implantation rate per embryo
transferred was significantly higher (P < 0.03) in
group 2 (46%) than in group 1 (29%). The cryo-augmented
delivery rate/oocyte retrieval was comparable in group
2 (36.3%) and in group 1 (28.6%). CONCLUSION: This
randomized study in an unselected population showed
a significantly higher CPR/embryo transfer and a tendency
toward a higher CPR/oocyte retrieval in patients receiving
blastocysts when compared with day 2 transfers.

8% or Utrogest((R)): results of a prospective, randomized
study.

The Crinone((R)) 8% preparation makes it possible
to administer natural progesterone (90mg) vaginally
once daily for luteal phase support (LPS). Until now,
no prospective, randomized studies have directly compared
this new preparation with widely used Utrogest((R))
capsules, which were originally designed for oral
administration but are used routinely as a vaginal
preparation. A prospective, randomized study investigated
126 patients undergoing cycles of in vitro fertilization
(IVF) and IVF/intracytoplasmic sperm injection (ICSI).
Patients received either Crinone((R)) 8% (n=73) vaginally
once daily or two Utrogest((R)) capsules (n=53) vaginally
three times daily (600mg). Clinical pregnancy rates
were comparable (28.8 versus 18.9%), as were clinical
abortion rates until 12 weeks of gestation (14.3 versus
10.0%) and clinical ongoing pregnancy rates (24.7
versus 17.0%) in the Crinone((R)) 8% and Utrogest((R))
groups, respectively. Forty-seven non-pregnant patients
were randomly selected to answer questions regarding
comfort during LPS. Crinone((R)) 8% had a clear advantage
over Utrogest((R)) as it resulted in less vaginal
discharge (P<0.01) and fewer application difficulties
(P<0.05). Twenty patients familiar with the alternative
preparation from a previous cycle also noted that
Crinone((R)) 8% was easier to apply (P<0.01) and less
time consuming (P<0.05) to use than Utrogest((R)).

of Vienna, Waehringer Guertel, Austria.
PURPOSE: To evaluate the impact of ascorbic acid of
different doses as additional support during luteal
phase in infertility treatment by means of a prospective,
randomized, placebo-controlled, group comparative,
double-blind study. METHODS: Voluntary daily oral
intake of either ascorbic acid (1, 5, or 10 g/day)
or Placebo for 14 days after follicle aspiration for
IVF-ET procedure. Data was obtained on 620 cases of
women, age <40 years, undergoing first IVF-embryo
transfer cycles in two private outpatient infertility
clinics. All women were stimulated by the same protocol.
The mean age was 31.73 (+/- 4.4 SD) years. RESULTS:
No differences in clinical pregnancy rate and implantation
rate were noted in statistical logistic regression
analysis between the four intake groups. CONCLUSIONS:
There was no clinical evidence of any beneficial effect,
as defined by main outcome measures, of ascorbic acid
on IVF-ET. Our data suggest there is no obvious value
of high dosed intake of vitamin C during luteal phase
in infertility treatment.

Hospital/University Medical Center, Department of
Obstetrics and Gynecology, USA. PURPOSE: To determine
if younger women with increased day 2 or 3 serum follicle
stimulating hormone (FSH) levels have a better prognosis
than older women with similar FSH elevations. METHODS:
Retrospective comparison of in vitro fertilization
(IVF) outcome from cycles from 1/1/97 to 9/30/99 according
to serum FSH < or = 12 vs > 12 and age < or = 38 or
> 38. Only cycles where follicular phase leuprolide
acetate was used were included. RESULTS: Age group
< or = 38 - clinical pregnancy rate (PR)/transfer
was 32% with lower FSH vs 28.6% with higher FSH. The
respective PRs for the older group were 30.3% and
5.5%. CONCLUSIONS: Oocyte quality as evidenced by
PRs following IVF-ET seems to be better in younger
vs older patients despite increased basal serum FSH
levels.

GnRH antagonist in older IVF patients. Retrieval
rates and clinical outcome. Chang PL, Zeitoun KM,
Chan LK, Thornton MH 2nd, Sauer MV.
Division of Reproductive Endocrinology, Department
of Obstetrics and Gynecology, Columbia University
College of Physicians and Surgeons, New York, New
York, USA. pchang@chpnet.org OBJECTIVE: To determine
if the use of a midcycle GnRH antagonist provides
better clinical outcomes and lower cancellation rates
in in vitro fertilization (IVF). STUDY DESIGN: We
examined all patients older than 40 years undergoing
IVF-embryo transfer cycles between January 1999 and
December 2000. Prior to June 2000, controlled ovarian
stimulation in women > or = 40 years was performed
with follicle stimulating hormone (FSH)/human menopausal
gonadotropin (hMG) only and no GnRH agonist or antagonist
(group I). After June 2000, following the release
of Ganirelix in the U.S., all women > or = 40 years
were stimulated with FSH/hMG + Ganirelix (group II).
Outcomes of IVF cycles prior to Ganirelix were compared
to results after its introduction. RESULTS: Cancellation
rates were significantly lower in group II (16%) as
compared to group I (67%) (P < .05). In patients with
oocytes retrieved, group II had a significantly higher
number of recovered oocytes (7.7 +/- 0.8 vs. 5.3 +/-
0.7, P < .05). However, the number of embryos transferred,
cumulative embryo scores, implantation rates and ongoing
pregnancy rates did not differ significantly between
groups. CONCLUSION: Although our results are preliminary,
the addition of GnRH antagonist avoids ovarian suppression
at the start of controlled ovarian hyperstimulation
and prevents the premature LH surge at midcycle. Thus,
more patients attempting IVF undergo oocyte retrieval,
although clinical outcomes may not necessarily be
improved.

OBJECTIVE: To determine the effect of increasing
experience in fluoroscopically guided selective salpingography
and tubal catheterization on radiation doses and screening
times, thus establishing a learning curve for the
procedure.DESIGN: Retrospective case note analysis.SETTING:
IVF center of an academic teaching hospital.PATIENTS:
Three hundred sixty-six patients with infertility
seen over 3.5 years.INTERVENTION(S): Fluoroscopically
guided selective salpingography and tubal catheterization.MAIN
OUTCOME MEASURE(S): Reductions in radiation doses
and screening times for different categories of selective
salpingography and tubal catheterization, expressed
as percentage reductions during the study period and
reductions per 10 procedures.RESULT(S): During the
study period, The median dose of radiation decreased
by 62.6%-71.9%, and the median screening time declined
by 61.5%-78.5%. Reductions per 10 procedures were
2.5%-4.2% and 2.7%-5%, respectively.CONCLUSION(S):
Significant reductions in radiation doses and screening
times start early in a clinical team's practice of
selective salpingography and tubal catheterization
and continue even as trainees are added to the pool
of operators.

Assessment of uterine receptivity by the endometrial-subendometrial
blood flow distribution pattern in women undergoing
in vitro fertilization-embryo transfer.

Department of Obstetrics and Gynecology, Taipei
Medical University and Hospital, Taipei, Taiwan.
OBJECTIVE: To investigate the correlation of blood
flow detected by color Doppler sonography in the endometrial-subendometrial
unit with pregnancy outcome of IVF-ET treatments.
DESIGN: Prospective clinical study. SETTING: University
setting. PATIENT(S): Six hundred twenty-three patients
selected prospectively on the day of ET. INTERVENTION(S):
Transvaginal ultrasound examination was performed
before ET. MAIN OUTCOME MEASURE(S): Association between
pregnancy outcome and distribution of endometrial-subendometrial
blood flow (primary outcome measure) and between pregnancy
rate and endometrial measurements as well as uterine
arterial blood flow (secondary outcome measures).
RESULT(S): The overall pregnancy rate was 28.4% (177/623)
per ET. The pregnancy and implantation rates of patients
with the presence of both endometrial and subendometrial
flow were 47.8% (64/134) and 24.2% (94/388); for patients
with subendometrial flow only, 29.7% (102/343) and
15.8% (153/967); and for patients with no detectable
endometrial-subendometrial flow, 7.5% (11/146) and
3.5% (13/376), respectively. The presence of both
endometrial and subendometrial blood flow is indicative
of good endometrial receptivity, whereas the absence
of both represents a poor uterine environment. Nondetectable
endometrial-subendometrial flow was associated with
women who were older, had a thinner endometrium, and
had higher uterine arterial resistance compared with
those women who had detectable flow. CONCLUSION(S):
Endometrial-subendometrial blood flow distribution
pattern assessed by transvaginal color Doppler before
ET is correlated with the implantation and pregnancy
rate of IVF treatment.
