In the surgical management of deep endometriosis, the issue of fertility is pivotal. There is a higher rate of infertility in a population of women with endometriosis as compared to the general population, even though the mechanisms are not yet elucidated. Patients with deep endometriosis can be referred to the surgeon for subfertility, but even when they are referred for chronic pain, future fertility considerations are taken into account in the planning of the surgery, as the patients are often young.
