Outcome of patients with endometriosis in assisted reproduction: results from in-vitro fertilization and oocyte donation

A retrospective analysis of our in-vitro fertilization (IVF) and oocyte donation programmes was carried out in order to gain clinical knowledge of the factors involved in the aetiology of the endometriosis-associated infertility.
