Abstract

Objective: To study the prevalence of oligo-anovulation in women suffering from endometriosis compared to that of women without endometriosis.

Design: A single-center, cross-sectional study.

Setting: University hospital-based research center.

Patient (s): We included 354 women with histologically proven endometriosis and 474 women in whom endometriosis was surgically ruled out between 2004 and 2016.

Intervention: None.

Main outcome measure(s): Frequency of oligo-anovulation in women with endometriosis as compared to that prevailing in the disease-free reference group.

Results: There was no difference in the rate of oligo-anovulation between women with endometriosis (15.0%) and the reference group (11.2%). Regarding the endometriosis phenotype, oligo-anovulation was reported in 12 (18.2%) superficial peritoneal endometriosis, 12 (10.6%) ovarian endometrioma, and 29 (16.6%) deep infiltrating endometriosis.

Conclusion(s): Endometriosis should not be discounted in women presenting with oligo-anovulation.

Keywords: Endometriosis; antimüllerian hormone; deep infiltrating endometriosis; oligo-anovulation.
