Department of Internal Medicine, Medical College of
Virginia, Virginia Commonwealth University, Richmond,
VA 23298-0111, USA. nestler@hsc.vcu.edu OBJECTIVE: Insulin
resistance and its compensatory hyperinsulinemia play
a key pathogenic role in the infertility of the polycystic
ovary syndrome. Numerous studies indicate that insulin-sensitizing
drugs can be used to enhance spontaneous ovulation and
the induction of ovulation in the syndrome. The aim of
this review is to summarize the studies in which insulin-sensitizing
drugs were used to increase ovulation rate or improve
fertility in women with the PCOS and to translate the
information into practical guidelines for the use of these
drugs by reproductive endocrinologists. DESIGN: Review
and critique of studies in which an insulin-sensitizing
drug was used to increase ovulation rate or improve infertility
in women with the polycystic ovary syndrome. MAIN OUTCOME
MEASURE(S): Ovulation rate and pregnancy rate. RESULT(S):
Studies have demonstrated that insulin-sensitizing drugs
can increase spontaneous ovulation, enhance the induction
of ovulation with clomiphene citrate, and increase clinical
pregnancy rates. CONCLUSION(S): An algorithmic approach
is provided for the use of insulin-sensitizing drugs to
treat the anovulation and infertility of women with the
polycystic ovary syndrome.

Endometrial cavity fluid is associated with poor ovarian
response and increased cancellation rates in ART cycles.
Levi AJ, Segars JH, Miller BT, Leondires MP.
Pediatric and Reproductive Endocrinology Branch, National
Institute of Child Health and Human Development, National
Institutes of Health, Bethesda, MD, USA. BACKGROUND: Endometrial
cavity fluid (ECF) is occasionally observed during assisted
reproductive technology (ART) cycles. However, few reports
have described its prevalence or significance. METHODS
AND RESULTS: We examined the relationships between ECF,
clinical pregnancy rate (CPR), tubal factor infertility
and ultrasound-visible (USV) hydrosalpinges. In 843 ART
cycles involving 721 patients, ECF was observed during
stimulation in 57 cycles and after human chorionic gonadotrophin
(HCG) administration in 12 cycles, with an overall incidence
of 8.2% (69/843). When ECF was observed during stimulation,
the cancellation rate due to poor ovarian response was
significantly higher (29.8 versus 16.9%, P <0.05) and
the CPR per started cycle was significantly lower (26.3
versus 42.4%, P <0.05) than cycles without ECF. When ECF
developed after HCG administration, the CPR was similar
compared with that of the group for which ECF was not
observed. In the 327 cycles involving tubal factor infertility
patients, USV hydrosalpinges were noted in 71 cycles (71/327;
21.7%), and ECF developed in five of those cycles (5/71;
7.0%). A total of 27 cycles during which ECF developed
(27/57, 47.4%) involved non-tubal factor patients. CONCLUSIONS:
ECF during stimulation was associated with increased cancellation
rates and lower CPRs per started cycle, and was not associated
with USV hydrosalpinges. Furthermore, ECF observed after
HCG administration did not impact CPR and may represent
a different clinical entity.

Anovulatory infertility: a report of four cases and
literature review. Anate M, Olatinwo AW. Department
of Obstetrics and Gynaecology, University of Ilorin Teaching
Hospital, Ilorin. Four cases of anovulatory/dysovulatory
infertility encountered in Ilorin, Nigeria are presented
and the literature extensively reviewed on the up-to-date
management of this aspect of infertility. All the patients
had bilateral tubal patency on hysterosalpingography (HSG)
and their husbands had normal seminal fluid analysis.
The first case, 30 years of age, had hyperprolactinaemia
with galactorrhoea, treated with bromocriptine given 2.5
mg twice daily. Another case, aged 27 years, had polycystic
ovarian syndrome with hyperprolactinaemia but no galactorrhea
This was treated with clomiphene citrate 100 mg daily.
The third case, 34 years old, had hypothyroidism with
hyperprolactinaemia and galactorrhea and was treated with
thyroxine. The last case, aged 32 years, had hyperprolactinaemia
and was treated with bromocriptine and clomiphene citrate.
None of the patients had demonstrable pituitary adenoma.
After the appropriate treatment, ovulatory menses were
restored in all the patients; two have been pregnant,
while the other two have not yet achieved pregnancy but
have having regular ovulatory menses. All the patients
are Nigerians.

Our understanding of Polycystic Ovary Syndrome (PCOS)
has been hampered by varying diagnostic criteria, and
ignorance of the etiology of the syndrome. PCOS women
are uniquely insulin resistant and obesity aggravates
this underlying predisposition to insulin resistance.
Diagnostic criteria which focus on hyperandrogenism and/or
menstrual irregularity are more likely to identify insulin
resistant women, than such criteria as abnormal gonadotropin
secretion or ovarian morphology. The lack of a clear etiologic
mechanism to the syndrome has led to a multitude of symptom-oriented
treatments with few therapies improving all aspects of
the endocrine syndrome of PCOS. Improving insulin sensitivity
has become established as a baseline treatment strategy
in PCOS. There are, however, few randomized controlled
trials of adequate power to provide an evidence based
guide to treatment in PCOS.

Porte de Trivaux, 92140 Clamart, France. Ledeenathalie@aol.com
BACKGROUND: The possibility that a specific cytokine profile
could be detected in the ovaries of patients with polycystic
ovarian syndrome (PCOS) was investigated. METHOD: Enzyme-linked
immunosorbent assay (ELISA) or bioassays were used to
assess the concentrations of leukaemia inhibitory factor
(LIF), tumour necrosis factor, interleukin 11, gamma interferon,
progesterone and oestradiol in follicular fluids from
preovulatory follicles collected after ovarian stimulation
from 15 PCOS patients, 15 infertile control patients with
regular cycles, and 8 oocyte donors. RESULTS: LIF and
progesterone concentrations were significantly lower in
the follicular fluid of PCOS patients (LIF median: 265
pg/ml) compared with controls (LIF median: 816 pg/ml);
LIF and progesterone follicular fluid concentrations were
correlated (r = 0.720, P = 0.0001). The LH/FSH ratio was
negatively correlated with LIF concentrations (r = - 0.714,
P = 0.0075). Although the PCOS and control patients did
not differ significantly in age, ovarian reserve or IVF
indication, the implantation rate was significantly lower
among the women with PCOS (IR = 9 versus 21%, P = < 0.01).
CONCLUSION: The specific cytokine profile of the PCOS
patients is probably related to the lower implantation
rate since follicular fluid LIF appears to function as
an embryotrophic agent.

Metformin does not enhance ovulation induction in clomiphene
resistant polycystic ovary syndrome in clinical practice.
Sturrock ND, Lannon B, Fay TN.
Department of Endocrinology, Nottingham City Hospital
NHS Trust, Hucknall Road, UK. nsturroc@ncht.trent.nhs.uk
AIMS: To determine whether metformin pretreatment has
beneficial effects in clomiphene resistant infertile women
with polycystic ovary syndrome (PCOS) in an infertility
clinic. METHODS: This was a randomized placebo controlled
double-blind crossover study of 3 months metformin (1500
mg day-1)/placebo, followed by 3 months metformin/placebo
together with clomiphene (50-100 mg for 5 days) for three
cycles in clomiphene resistant women with PCOS. The primary
outcomes were restoration of spontaneous menses, ovulation
induction (spontaneous or clomiphene induced) and pregnancy.
Secondary endpoints were changes in biochemical parameters
related to androgens and insulin. RESULTS: Twelve women
completed the metformin arm and 14 the placebo arm. Spontaneous
menstruation resumed in five metformin treated patients
and in six placebo treated women, P=0.63. No women given
metformin spontaneously ovulated, although one patient
given placebo did, P=0.30. There was no difference in
the efficacy of clomiphene between the two groups with
ovulation being induced in five (out of 12) metformin
treated women and four (out of 14) placebo treated women,
P=0.63. Pregnancy occurred in three (out of 12) women
given metformin and two (out of 14) women given placebo,
P=0.59. CONCLUSIONS: Metformin is not always beneficial
when given to clomiphene resistant infertile women with
PCOS in clinical practice.

Hepatic dysfunction associated with moderate ovarian
hyperstimulation syndrome. A case report. Elter K, Scoccia
B, Nelson LR.

Department of Obstetrics and Gynecology,
University of Illinois College of Medicine, Chicago, USA.
BACKGROUND: Liver dysfunction is a rare complication of
severe ovarian hyperstimulation syndrome (OHSS). Based
on a MEDLINE search from 1966 to September 2000, we report
the second case of liver dysfunction associated with moderate
OHSS. In addition, this is the first report of moderate
OHSS with serum progesterone levels during the first trimester
of pregnancy higher than the upper limit of normal for
a third-trimester gestation. CASE: A 33-year-old nulligravida
with a history of infertility had previously undergone
three failed cycles of assisted reproduction. During her
fourth attempt at in vitro fertilization and intracytoplasmic
sperm injection, she developed moderate OHSS 11 days after
embryo transfer. She was managed on an outpatient basis.
Her serum progesterone and liver enzyme levels were significantly
elevated, as is unusual for the moderate picture of OHSS
in this patient. CONCLUSION: Hepatic dysfunction is not
limited to the severe forms of OHSS. Liver function should
be analyzed even in moderate cases. Further study is needed
to understand the role of elevated liver function tests
and serum progesterone in the pathogenesis of OHSS.

Is luteinizing hormone needed for optimal ovulation
induction? Balasch J, Fabregues F.

I Sunyer (IDIBAPS), Barcelona, Spain. jbalasch@medicina.ub.es
The role of luteinizing hormone in the natural menstrual
cycle is not disputed. There are, however, a variety of
opinions regarding the potential role of exogenous luteinizing
hormone in ovulation induction and whether it is actually
needed. The recent introduction into clinical practice
of recombinant gonadotropins has been paralleled by recent
advances in the knowledge of the endocrine and paracrine
mechanisms that regulate human folliculogenesis. On this
basis, this review analyses whether or not all patients
need luteinizing hormone for follicular growth stimulation.
In addition, new opportunities for improved treatment
are considered as a result of the availability of recombinant
human luteinizing hormone both in patients with ovulatory
disorders and those undergoing multiple follicular development
for assisted reproduction.

Clomiphene citrate for unexplained subfertility in
women. Hughes E, Collins J, Vandekerckhove P.

McMaster University, 1200 Main St West, Hamilton, Ontario,
Canada, L8N 3Z5. hughese@fhs.csu.mcmaster.ca
BACKGROUND: The effectiveness of clomiphene citrate has
been clearly demonstrated in the treatment of sub-fertility
associated with oligo-ovulation. The multiple pregnancy
rate associated with clomiphene, however, is elevated
at approximately 10%. Additional side effects associated
with clomiphene use also include hot flashes, mood swings,
headaches and visual disturbances. A variety of publications
have raised the question of increased ovarian cancer risks
associated with clomiphene use. Understanding the effectiveness
of clomiphene in this patient group is therefore, extremely
important. OBJECTIVES: To determine the effectiveness
of clomiphene citrate given to women with unexplained
subfertility, in a dose range of 50-250 mg for up to 10
days. The primary outcome was clinical pregnancy. MAIN
RESULTS: Clomiphene appeared to be superior to no treatment
or placebo. The common odds ratios for clinical pregnancy
per patient and per treatment cycle were 2.37 (1.22-4.62)
and 2.5 (1.35-4.62) respectively. Although there was some
clinical heterogeneity between studies, the results were
statistically homogeneous (p>0.1). These data suggest
statistically and clinically significant improvement in
pregnancy rate following clomiphene citrate in women with
unexplained infertility. REVIEWER'S CONCLUSIONS: Although
the absolute treatment effect is small, given the low
cost and ease of administration, clomiphene citrate appears
to be a sensible first choice treatment for women with
unexplained infertility. However, in making this treatment
choice, concerns of long-term use and ovarian cancer risk,
multiple pregnancy risk and minor symptoms should be discussed.
Given the extensive use of clomiphene in ovulatory women
and recent concerns associated with long term use, a definitive
trial with adequate power is warranted to establish effectiveness
in women with unexplained subfertility.

University, Izumo, Japan. taka27@shimane-med.ac.jp
OBJECTIVE: To evaluate the significance of an LH variant
with a mutant beta-subunit (Trp8 to Arg8 and Ile15 to
Thr15) in gynecologic disease, including infertility.
DESIGN: Clinical study. SETTING: Department of Obstetrics
and Gynecology, Shimane Medical University Hospital, Izumo,
Japan. PATIENT(S): Two hundred forty-five Japanese women
with endocrine disorders and/or gynecologic disease and
153 healthy, nonpregnant, fertile Japanese women. INTERVENTION(S):
A blood sample was collected. MAIN OUTCOME MEASURE(S):
The ratio of LH values from the SPAC-S and Immulyze assays
(LH ratio: SPAC-S LH/Immulyze LH) was used to determine
variant (< or =0.5) or wild-type (>0.5) LH status according
to a demonstrated relation between the ratio and the sequence
of the LH beta-subunit gene. RESULT(S): The LH ratio was
lower (0.80+/-0.31) in the 245 patients than in the controls
(1.00+/-0.38), and the variant was more frequent in the
patients (18.4%) than in the controls (8.5%). We found
no difference in the frequency of the variant between
infertile and fertile patients. The prevalence of infertility
did not differ between patients with variant LH and patients
with normal LH. Ovulatory disorders, hyperprolactinemia,
premature ovarian failure, menstrual disorders, and luteal
insufficiency were significantly more frequent in patients
with the variant. CONCLUSION(S): Variant LH may contribute
to female reproductive disorders, including infertility
and premature ovarian failure.

Female patients with cystic fibrosis suffer from reproductive
endocrinological disorders despite good clinical status.
Johannesson M, Landgren BM, Csemiczky G, Hjelte L, Gottlieb
C.
Stockholm CF Center, Department of Pediatrics, Huddinge
Hospital, Sweden. Ten women with cystic fibrosis (CF)
were evaluated with regard to hormonal profiles during
a natural and a clomiphene citrate (CC) stimulated cycle.
Five of the women were found to be anovulatory during
a natural cycle. All women except one did respond with
ovulation to CC stimulation indicating adequate ovarian
response. Neither did they show increased follicle-stimulating
hormone (FSH) concentrations on day 10 after CC treatment
confirming normal ovarian reserve. Clinically the anovulatory
women differed from the ovulating in two aspects: more
profound essential fatty acid deficiency (EFAD) and higher
peak/basal insulin response during an oral glucose tolerance
test. The anovulatory women had significantly lower luteal
oestradiol and progesterone but higher total testosterone
concentrations when compared to healthy controls and the
ovulatory CF women. The pathological insulin response
and high testosterone concentrations resemble those seen
in women with polycystic ovarian (PCO) syndrome. However,
the CF patients in our study had normal ovaries, as deduced
from ultrasound examination and normal luteinizing hormone
(LH)/FSH ratio. It is suggested that EFAD as well as hypersecretion
of insulin may be of importance for the observed ovarian
dysfunction. Further studies are needed to evaluate the
relation between ovulatory mechanisms and EFAD in CF women
as well as studies to compare anovulatory CF women with
women with PCO syndrome.

Child rate, pregnancy outcome and ovarian function
in females with classical 21-hydroxylase deficiency.
Jaaskelainen J, Hippelainen M, Kiekara O, Voutilainen
R.
Department of Pediatrics, Kuopio University Hospital,
Finland. BACKGROUND: Ovulatory disorders and decreased
fertility rates have been found in females with classical
21-hydroxylase deficiency (21-OHD). We analyzed the pregnancies
of 29 females with classical 21-hydroxylase deficiency
and examined 16 of these women in a cross-sectional study.
METHODS: The child rate of the 29 patients was compared
with that in the general Finnish female population with
equal age distribution.The cross-sectional study of the
16 patients included a standardized questionnaire, clinical
examination, ultrasonography of the internal genitalia,
basal measurements of serum steroids, sex hormone binding
globulin, PRL, gonadotropins and plasma ACTH. RESULTS:
The child rate was significantly lower than that in the
general population (0.34 vs 0.91; p<0.001). A total of
13 pregnancies could be registered. From these pregnancies,
ten healthy children were born, all for females with a
simple virilizing disease. None of the nine females with
salt wasting 21-OHD had any children or had sought treatment
for infertility. In the cross-sectional study, females
with regular menses (5/16; 31%) had well controlled adrenal
androgen secretion and they had normal serum progesterone
concentrations whereas the females with irregular menses
(11/16; 69%) were often undersubstituted and presented
with high serum progesterone concentration in the follicular
phase. Polycystic ovaries could not be detected in any
of these patients. CONCLUSIONS: Females with simple virilizing
21-OHD often have irregular menses but their final prognosis
for fertility seems to be better than previously reported.
On the contrary, our study confirms the extremely low
child rate in the salt wasting group.
Impact of metformin therapy on ovarian

This study was designed to determine if metformin therapy
improves ovarian stimulation and IVF outcomes in coasted
patients with clomiphene-resistant polycystic ovarian
syndrome (PCOS). A retrospective#10; data analysis was
performed on women with clomiphene citrate-resistant PCOS
treated with or without metformin, who underwent 72 cycles
of IVF-embryo transfer with intracytoplasmic sperm injection
(ICSI).#10; In 59 cycles, patients were coasted to allow
oestradiol concentrations to drop before human chorionic
gonadotrophin administration. In patients undergoing coasting,
the outcome of IVF with ICSI was compared#10; in those
who were treated and untreated. In patients treated with
metformin, follicular fluid concentrations of testosterone
and insulin were significantly lower (60.5 +/- 5 versus
79.1 +/- 6#10; ng/dl; P < 0.05 and 18 +/- 2.5 versus 22
+/- 2.4 &mgr;IU/ml; P < 0.05 respectively), and the mean
number of oocytes retrieved (22.3 +/- 2.4 versus 19.7
+/- 1.6) did not differ.#10; The metformin-treated group
showed an increase in the mean number of mature oocytes,
oocytes fertilized and cleaving embryos (4-cell or greater
by 72 h). However, in the group of patients undergoing
coasting,#10; maximum oestradiol concentrations and number
of days of coasting were all lower in the metformin-treated
group with increased clinical pregnancy rates (71 versus
30%, P < 0.05). Therefore, metformin#10; use appears beneficial
in improving IVF outcomes in clomiphene citrate-resistant
PCOS patients. #10;
