Use of combined hormonal contraceptives for the treatment of endometriosis-related pain: a systematic review of the evidence

The available literature suggests that CHC treatment is effective for relief of endometriosis-related dysmenorrhea, pelvic pain, and dyspareunia; however, the supportive data are of low quality. Furthermore, insufficient data exist to reach conclusions about the overall superiority of any given CHC therapy, and the relative benefit in comparison to other approaches. Additional high-quality studies are needed to clarify the role of CHC agents and other treatments in women with endometriosis-related pain.
