Infertility in patients with bowel endometriosis

The impact of bowel endometriosis on fertility is unclear, and the optimal management of patients who wish to conceive is not well-defined. Infertile patients with bowel endometriosis may either undergo surgery to enhance fertility or assisted reproductive technology (ART). It is necessary to consider that some complications may occur in patients undergoing ART because of the ovarian stimulation needed during these procedures. Interpretation of the available data on fertility outcomes after colorectal surgery for deep endometriosis is difficult as several studies do not distinguish patients with real infertility from those wishing to conceive without proven infertility and outcomes of complex surgery are operator-dependent. The effect of bowel surgery to increase the likelihood of spontaneous conception is yet to be established. Limited data are available on fertility outcomes after the removal of endometriotic nodules without the excision of bowel endometriotic implants.
