GnRH analogs versus expectant management in minimal and mild endometriosis-associated infertility.

The aim of the present study is to compare the outcome of GnRH analog treatment versus expectant management in infertile patients with minimal and mild endometriosis. From January 1987 to December 1990, 14 patients with stage I and II endometriosis underwent a six-month course of the GnRH analog buserelin, whereas 38 patients underwent expectant management. The two groups were comparable as to mean age of the patients, mean length of infertility prior to diagnosis and mean scores of endometriosis. No major tubal or male factor of infertility was present in any patient. Cumulative pregnancy rates at 12 months were comparable in the two groups (48% for GnRH analog treatment and 42% for expectant management). Expectant management should therefore be considered the most cost-effective option in the management of mild endometriosis-associated infertility.
