Effects of laparoscopic cystectomy for ovarian endometrioma on ovarian response of controlled ovarian hyperstimulation / 中国微创外科杂志

ABSTRACT

0.05).The pregnancy rate was 41.5%(17/41) in the(Non-cystectomy) Group,33.3%(23/69) in the Laparoscopic Group,and 25.5%(14/55) in the Open Group,respectively,without significant differences(?~2=2.754,P=0.252).A total of 86 patients(90 cycles) were given a unilateral cystectomy,including 37 cycles in the Open Group and 53 cycles in the Laparoscopic Group.In the 37 cycles of the Open Group,the number of dominant follicles was less in affected ovary(4.41?4.02) than in contralateral one(6.14?4.37)(t=-2.364,P=0.024),whereas in the 53 cycles of the Laparoscopic Group,the number of dominant follicles was significantly less in affected ovary(3.33?3.50) than in contralateral ovary(6.40?3.61)(t=-5.358,P=0.000).Conclusions Both laparoscopic and open cystectomy of ovarian endometrioma may cause damage to ovarian response of COH.
