Paracetamol or NSAID. A short trial can be considered for pain, and these medicines may be offered. The trials behind that are very low quality. (Uncertain [1] [2])
TENS. Small trials found some improvement in pain or quality of life. They are low quality, and ESHRE makes no recommendation. (Uncertain [2])
Combined pill. It reduces pain with periods, pain with sex, and pelvic pain. It does not permanently reduce later fertility. It is not used to help you conceive. (Established [1] [2] [3])
Progestogens. Progestogens reduce endometriosis pain. Side effects differ between products. (Established [1] [2])
Hormonal coil. A levonorgestrel coil reduces endometriosis pain. It is also a contraceptive. (Established [2] [3])
GnRH agonist. Second line, because of side effects from low oestrogen. Add-back treatment (low-dose oestrogen and progestogen) is used to protect bone and limit those effects. (Likely [2] [3])
GnRH antagonist. This can be considered. The recommendation is weak, and it is second line. Add-back treatment (low-dose oestrogen and progestogen) limits low-oestrogen effects. (Likely [2] [1])
Excision or ablation. Surgery is one option to reduce pain. A Cochrane review cited for this is uncertain about the size of the effect on overall pain. Lesions can return. (Likely [1] [2] [3])
Ovarian cyst surgery. Removing the cyst wall (cystectomy) is preferred to reduce pain and recurrence. Draining and ablating it may spare more ovarian reserve when fertility is a priority. (Likely [1] [2])
Hysterectomy. Removal of the womb is not a cure. It is considered when other care has not helped and pregnancy is not planned. Visible lesions should be removed at the same time. (Uncertain [3] [2] [1])
Hormones and conception. Hormonal treatment is not offered to raise the chance of conceiving without assistance. (Established [1])
Surgery and conception. Removing peritoneal disease, or treating an endometrioma, can improve the chance of conceiving without IVF. (Likely [1])
Fertility treatment. Ovulation induction, insemination, or IVF may be offered. Among women with infertility, as many as 25 to 50 percent have endometriosis. (Likely [3])
Physio and psychology. Physiotherapy and cognitive behavioural therapy can reduce pain for some people. No specific non-medical treatment is recommended, because benefits and harms are unclear. (Uncertain [3] [2])
