Effect of different operation ways to excision of ovarian endometriomas on IVF-ET outcomes

Objective: To investigate different operating ways to excision of ovarian endometriosis prior to IVF-ET affects ovarian response of controlled ovarian hyperstimulation and fertility outcomes.Methods A retrospective study on 67women with ovarian endometriomas(previously diagnosed by open or laparoscopic surgery) receiving COH for IVF-ET regarding their outcomes of assisted reproduction.A group:21 patients had received a laparoscopic cystectomy;B group:16patients had undergone an open cystectomy;C group:30 patients had been untreated with cystectomy.Results Both laparoscopic and open cystectomy of ovarian endometriomas are no significant difference in number of superiority follicles,number of oocytes obtained,number of nomally developed embryos,number of embryos transferred and pregnancy rate.Numbers of antralfollicles in the A and B group were significant fewer than the C group(P0.05).There was no difference in the dose and duration of FSH application between laparoscopic and open cystectomy group(P0.05),but the does and duration of FSH application in the laparoscopic and open cystectomy groups were significantly more than the control group(P0.01).The numbers of antralfollicles and preovulative follicles were statistically different between the study and control groups(P0.05).Conclusion Both laparoscopic and open cystectomy of ovarian endometriomas maycause damage to ovarian function.There was no difference in the two operation groups on IVF-ET outcomes.
