Clinical characteristics and surgical management of endometriosis‐associated infertility: A multicenter prospective cohort study

To study clinical and surgical characteristics and the relationship between endometriosis lesion types and conception rate after surgery in infertile women with endometriosis. Based on the severity of endometriosis lesion type, deep infiltrating endometriosis (DIE) (39.7%) was the most common lesion. Endometriosis patients had a single lesion type (46.1%), two lesion types (37.7%), or three lesion types (16.2%) with significant differences between regions. Significant differences in mean Endometriosis Fertility Index scores between endometriosis lesion types and patients with one, two, and three types of lesions were observed (P < 0.001). However, most (68.8%) women conceived naturally after the surgery. Half of the women with a single lesion type conceived after the surgery, of which most (13/16, 81.2%) had SUP, followed by OMA (12.5%) and DIE (6.3%). Women with SUP and only one type of endometriotic lesion were more likely to conceive post‐surgery.
