title: Surgical resection or aspiration with ethanol sclerotherapy of endometrioma before in vitro fertilization in infertilie women with endometrioma.
abstract: OBJECTIVE
  To evaluate whether the surgical resection or aspiration with ethanol sclerotherapy (AEST) of endometrioma before in vitro fertilization (IVF) affect controlled ovarian stimulation (COS) and IVF outcome in the infertilie women with endometroma undergoing IVF.
  
  
  METHODS
  In this retrospective cohort study, 101 consecutive IVF/intracytoplasmic sperm injection cycles that were performed in 101 patients with endometrioma(s) between January 2008 and December 2012 were included. Before IVF, 36 patients underwent surgical resection of endometrioma (resection group), 29 patients had transvaginal endometrioma AEST (aspiration group), and 36 patients did not take any surgical intervention (control group). The three groups were compared in terms of COS and IVF outcomes.
  
  
  RESULTS
  Total antral follicle count was significantly lower in the resection group than in the aspiration or control group. The numbers of follicles with a diameter of 14 to 17 mm on the human chorionic gonadotropin day, retrieved oocytes, mature oocytes, and fertilized oocytes were significantly lower in the resection group than in two other groups. However, three groups were similar in terms of clinical pregnancy rate (CPR) per initiated cycle, CPR per embryo transfer, embryo implantation rate, and miscarriage rate.
  
  
  CONCLUSIONS
  Neither of surgical resection and AEST of endometrioma before IVF treatment can give any beneficial effect on IVF outcomes. Moreover, surgical resection of endometrioma can affect the ovarian reserve and ovarian response during COS.
