Within recent years GnRH agonists have gained increasing importance in the treatment of reproductive failure.

In cases of endometriosis and uterus myomatosus, GnRH agonists achieve high remission rates and may avoid or at least postpone the need for surgical intervention. The physiological basis and current clinical strategies are discussed.
