Oligo-anovulation is not a rarer feature in women with documented endometriosis.
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.
