title: Human in vitro fertilization and embryo transfer at the University of Texas, Houston.
abstract: The current clinical and laboratory protocols of the in vitro fertilization program at the University of Texas at Houston are described and detailed. Most patients treated have tubal disease, with a limited number of couples having male factors. Clomiphene citrate (50 mg/day, cycle days 5-9) with or without added menopausal gonadotropins is the principle agent for enhanced follicular recruitment. Follicular development is monitored primarily with daily ultrasonography, and human chorionic gonadotropin (hCG) is given when the largest follicle reaches or exceeds 20-mm mean diameter. The culture media used are modifications of Ham's F-10. Mature oocytes are preincubated for 5 hr before insemination with 50,000 motile sperm per oocyte. Using these protocols, the clinical pregnancy rate is 11.6% per laparoscopy (11/95) and 16.2% per embryo transfer (11/68).
