Transvaginal Low-level Laser Therapy to Improve Pelvic Pain and Sexual Function in Patients with Endometriosis.

Dyspareunia is defined as pain with penetrative sexual intercourse. Women with endometriosis have a nine-fold increased risk of dyspareunia, when compared to the general female population. A prospective single-blinded randomized controlled trial will be performed evaluating the change in pelvic pain and sexual satisfaction scores from baseline to 6 weeks after treatment with transvaginal photobiomodulation therapy or sham therapy. Treatment will involve 9 planned treatment sessions over 3-4 weeks. 40 women will be included in the study.
