The pathophysiology of endometriosis-associated pain involves inflammatory and hormonal alterations and changes in brain signaling pathways. Although medical treatment can provide temporary relief, most patients can achieve long-term sustained pain relief when it is combined with surgical intervention. Owing to its complexity, there is an ongoing debate about how to optimally manage endometriosis-associated pain. We believe optimal management for this condition requires: 1) possible egg preservation in affected young patients with and without endometriomas; 2) preoperative medical suppression to inhibit ovulation and to avoid removal of functional cysts that might look like endometriomas; and 3) postoperative hormonal suppression to decrease recurrence, but this treatment should be modified according to disease severity, symptoms, and fertility goals.
