Treatment of colonic endometriosis with a gonadotropin releasing hormone agonist and pregnancy after human menopausal gonadotropin/intrauterine insemination. A case report.

A woman with longstanding primary infertility and progressive, symptomatic rectal endometriosis was treated with daily leuprolide acetate for nine months. All bowel symptoms subsided. The patient was treated with human menopausal gonadotropin and intrauterine insemination prior to discontinuation of the leuprolide acetate, resulting in a twin pregnancy.
