What this Trial Is About

Women suffering from endometriosis and/or adenomyosis may also suffer from infertility. GnRH agonist injection could improve implantation and therefore increase the pregnancy rate in these patients. This study was designed to evaluate effects of the additional of GnRH agonist (single or 2 doses) to the routine oestrogens and progestins use as support before Frozen Embryon Transfer as compared to oestrogens and progestins only.
