Reproductive outcomes after laparoscopic surgery in infertile women affected by ovarian endometriomas, with or without fertilisation: results from the SAFE (surgery and ART for endometriomas) trial.

We performed a retrospective cohort study, namely "Surgery and ART for Endometriomas" (SAFE) trial (Clinical Trial ID: NCT03717870), including women who underwent laparoscopic cystectomy for endometrioma before first IVF and compared their reproductive outcomes with the ones of women without endometriosis and with unexplained infertility, tubal factor or male factor infertility. We found that women who underwent previous laparoscopic cystectomy for endometrioma had higher FSH and LH levels between the 2nd and 5th day of the cycle before IVF, required higher doses of gonadotrophins for ovarian stimulation and had a lower number of retrieved oocytes compared with other types of infertility. Nevertheless, pregnancy and delivery rates remain comparable to other causes of infertility.
