Analysis of 25 infertile patients treated consecutively by in vitro fertilization at Bourn Hall

Abstract

Twenty-five infertile women suffering from tubal disorders were treated consecutively by in vitro fertilization over a 14-day period. Follicular growth in 24 of them was stimulated with clomiphene citrate, ovulation being induced by an endogenous surge of luteinizing hormone or an injection of human chorionic gonadotropin. One patient was given tamoxifen and had an endogenous luteinizing hormone surge. One or more oocytes were fertilized, and at least one embryo was replaced in 19 patients. Nine pregnancies were established, and eight infants have been delivered, a pregnancy rate of 36% per laparoscopy and 47% per replacement. A detailed analysis of each patient is presented.
