Detailed description: Randomized clinical trial the use of levonorgestrel releasing intrauterine system. Objectives: To evaluate and compare the efficacy of- levonorgestrel releasing intrauterine system (LNG-IUS) in relation to the subdermal implant releasing etonogestrel (ENG) in the control of chronic pelvic pain and / or dysmenorrhea in women with endometriosis. Methods: Will be assessed 100 women, aged 18-45 years, diagnosis of endometriosis confirmed by laparoscopy or laparotomy that presents chronic pelvic pain and / or dysmenorrhea. The study will be experimental, randomized , (50 women will be allocated to the LNG-IUS and 50 women will use the implant subdermal ENG). Women will be invited to participate in the study on the day and having the Family Planning Clinic with pelvic pain complaints and / or dysmenorrhea with a confirmed diagnosis of endometriosis in search of inserting a LNG-IUS. That day will be invited to be allocated by lottery (through a system of computer generated randomization; with opaque and sealed envelopes), the group that will use LNG-IUS or subdermal implant ENG. At the inclusion in the study will be held the insertion of the LNG-IUS or ENG implant and on this day the pain will be evaluated by visual analogue scale (VAS) of pain and applied the evaluation questionnaire of endometriosis. It will be a calendar to record delivered daily bleeding and EVA for daily assessment of pain. Women will return each 30 days (± 3 days) where the pain of registration will be evaluated by EVA and will be collected the bleeding and delivered a new calendar for the next 30 days. The end of the study It is expected to 180 days post-insertion of the LNG-IUS or the implant and, in the latter evaluation, will again be applied questionnaire. Cancer antigen 125 (CA-125)will be evaluated at baseline and at last follow-up ( +/- 180 days). Inclusion criteria:

- Women aged 18 to 45

- Absence of pregnancy

- Patients with chronic pelvic pain and / or dysmenorrhea with pain scores ≥ 4 on EVA

pain and surgical and histopathological diagnosis of endometriosis in 14 last three months to two years, according to the current classification of the American Society for Reproductive Medicine

- Accept participate and sign the consent form and clarified.
