Endometriosis

Tissue similar to the womb lining grows outside the womb, causing pain and sometimes fertility problems.

Overview

Endometriosis affects around 1 in 10 women of reproductive age. Common symptoms include painful periods, pain during or after sex, pelvic pain and difficulty conceiving.

Diagnosis is often delayed by several years. Ultrasound or MRI can identify some forms; laparoscopy may still be needed.

What is well established

Endometriosis is associated with reduced fertility, but many people with endometriosis conceive naturally or with treatment.
Pain is not a reliable guide to the extent of the disease.
A range of hormonal and surgical treatments can help with pain.

Uncertain or emerging evidence

The exact causes are not fully understood.
The benefit of surgery for fertility depends on the type and stage of disease, and evidence is mixed for some groups.
