Objective: To evaluate follicle loss in ovarian tissue after laparoscopic excision by the stripping technique in endometriomas versus benign nonendometriotic ovarian cysts. Methods: Cystectomy samples obtained from 127 ovaries from 104 patients (mean age, 29.05 +/- 05 years; range, 19-40 years) by laparoscopic excision (61 endometriomas and 66 benign nonendometriotic cysts) were evaluated for follicle loss. The samples including normal ovarian tissue were graded on a semiquantitative scale from 0 to 4, where 0 was complete absence of follicles and 4 was the pattern of primary and secondary follicles seen in a normal ovary. The results from endometriomas were compared with those from nonendometriotic cysts. Results: There were no differences in mean tissue thickness, or number of primordial, primary, or secondary follicles between the endometriomas and the nonendometriotic cysts (P>0.05). Ovarian cortex was detected in 92% and 82% of the endometriomas and nonendometriotic samples, respectively, (P=0.081). Semiquantitative scoring of ovarian tissue was significantly higher in endometriomas (1.64 +/- 1.35 versus 1.11 +/- 1.22, P=0.022). Conclusion: In up to 92% of the cystectomy samples, normal ovarian tissue was found adjacent to the benign cyst; however, functional follicle loss was slightly, but significantly, higher in the endometriomas.
