Comparing ovarian reserves after laparoscopic excision of ovarian endometriotic cysts and ovarian nonendometriotic cysts

Objective: This study compared ovarian response to controlled ovarian hyperstimulation between women who previously underwent laparoscopic excision of an ovarian endometriotic monolateral cyst with women who had surgery for ovarian nonendometritoic monolateral cysts. Materials and methods: This was a retrospective review of women who underwent controlled ovarian hyperstimulation for in vitro fertilization or intracytoplasmicsperm injection after laparoscopic excision of an ovarian endometriotic monolateral cyst (group A) after surgery for ovarian nonendometritoic monolateral cysts (group B). The contralateral intact ovary and the operated ovary of each patient were compared in terms of the number of follicles with a mean diameter gt;15 mm at the time of human chorionic gonadotropin administration between groups A and B. An unpaired Student's t-test was used to investigate differences between groups A and B. Results: Thirteen (13) and 7 women were recruited for groups A and B. Although the mean (±standard deviation [SD]) number of follicles > 15 mm of the contralateral intact ovary was not significantly different between groups A and B (4.9 ± 2.7 versus 4.6 ± 3.0), which suggested no significant difference in the potential ovarian response to controlled ovarian hyperstimulation between the two groups, the mean (±SD) number of follicles > 15 mm of the operated ovary in group A was reduced significantly, compared with that in group B (1.8 ± 1.1 versus 3.9 ± 2.3). Conclusions: The ovarian reserve after laparoscopic excision of endometriotic cysts is reduced more than after surgery for nonendometriotic cysts.
