This study compared two IVF-ET ovarian stimulation protocols in patients with various stages of endometriosis who were resistant to conventional therapies: an ultralong protocol using at least 60 days of gonadotropin-releasing hormone agonist (Gn-RHa) pretreatment before menotropin stimulation, versus a long protocol with Gn-RHa started at midluteal phase followed by exogenous gonadotropins after pituitary suppression. Estradiol response and numbers of retrieved oocytes, fertilized oocytes, cleaved oocytes, and transferred embryos were similar between groups, but the clinical pregnancy rate per transfer was higher with the ultralong protocol (67% vs 27%). The miscarriage rate reported was 14% (2/14) in the ultralong group. This paper is centrally about endometriosis — it evaluates IVF stimulation outcomes after prolonged Gn-RHa pretreatment in endometriosis patients.

Abstract

Two protocols were scheduled for in vitro fertilization and embryo transfer (IVF-ET) in patients with various stages of endometriosis who were resistant to conventional therapies. In the ultralong protocol (21 patients), gonadotropin releasing hormone agonist (Gn-RHa) was administered for at least 60 days prior to ovarian stimulation along with menotropin until human chorionic gonadotropin was injected. In the long protocol (11 patients), Gn-RHa was started at the midluteal phase and exogenous gonadotropin was commenced between the third and the seventh day of the menstrual cycle after pituitary suppression. The estradiol response and the number of retrieved oocytes, fertilized oocytes, cleaved oocytes, and transferred embryos were similar in both groups but the clinical pregnancy rate per transfer was superior in the ultralong protocol (67 vs 27%). The miscarriage rate was 14% (2/14) in the ultralong protocol. Prolonged Gn-RHa suppression of ovarian function before superovulation may overcome some causes of infertility in patients with endometriosis.
