Study Summary

This prospective randomized trial evaluates whether one can predict which infertile women with endometriosis who are candidates for in vitro fertilization will benefit from prolonged therapy with a GnRH agonist by the determination of the absence of endometrial expression of the integrin, alpha v, beta 3 vitronectin. This is a prospective randomized trial in which all patients will undergo endometrial biopsy prior to initiation of ovarian stimulation for in vitro fertilization and then undergo randomization to a three month course of a depot preparation of the GnRH agonist leuprolide acetate in depot suspension prior to ovarian stimulation or standard therapy. prio

Primary Outcome

Number of patients who responded to controlled ovarian stimulation as evidenced by implantation of embryo. Implantation confirmed by ultrasound at 6 1/2 weeks of pregnancy.
