[GIFT: reproductive reality for the sterile couple]
Abstract:
From June 1987 thru December 1988, 72 patients entered our gamete intrafallopian transfer (GIFT) program. The average age of our patients was 28 years with of infertility. The causes for being selected to the program were: Unknown (14), Endometriosis (14), Male (13), Ovarian (5), Cervical (9), Tubo-peritoneal (6) and oocyte donation (11). Different follicular stimulation protocols were used, with combinations of clomiphene citrate, human menopausal gonadotropins (hMG) and follicle stimulating hormone (FSH). Monitoring by serial ultrasound scanning until two or more follicles were 16-18 mm and estradiol levels were over 700 pg/ml, after which 10,000 IU of human chorionic gonadotropins (hCG) were injected. After 36 hrs oocyte retrieval was performed. There were 19 clinical pregnancies (26.4%). We feel that this new technique offers a bright and promising future for our infertile population.

Overview of the Reproductive System
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...
