Endometriosis reveals the presence of glands or endometrial stroma outside the uterus, responsible for pain and infertility. Adenomyosis illustrates an invagination of endometrial islets within the myometrium, leading to a disturbance of its contractile activity, also potentiated by local hyperestrogenism. These two pathologies are often associated, and express an alteration of the eutopic endometrium by pro-inflammatory markers responsible for a lower implantation rate. GnRH agonists are known to decrease these pro-inflammatory markers (cytochrome P450 and Cox 2 aromatase) in the eutopic endometrium of women with endometriosis or adenomyosis. Patients will received 1 or 2 injection of GnRH delay agonist (Decapeptyl 3mg) approximately 1 month before the frozen embryo transfer.
