ICSI

ICSI, or intracytoplasmic sperm injection, is performed for men having extremely low sperm counts or extremely high percentages of abnormal shaped sperm or nonmoving sperm. Some men may have no sperm at all due to absence or damage of the duct system that allows the flow of sperm from the testicle. Other men who have had an unsuccessful vasectomy reversal may also suffer from this problem. In the ICSI procedure, a single sperm is injected directly into the egg. This is accomplished in the laboratory using a high-powered microscope and small glass injection needles. The process is controlled by an embryologist using precision equipment. High fertilization and pregnancy rates are usually seen. .
