 The ovarian reserve will be evaluated pre- and postoperatively for each patient. It will be determined by plasmatic AMH anti-Mullerian Hormone and ultrasound antral follicle count. Women with undetectable preoperative plasmatic AMH will be excluded from the study. Plasmatic AMH and antral follicle count will be measured at 1, 3, 6, 12 and 24 months during the postoperative follow-up.
