Center's  multidisciplinary team offers top surgical expertise in excisional nerve sparing, radical and fertility preserving treatment options of severe infiltrating endometriosis. Our aim is to avoid multiple surgical operations for deep endometriosis and clear the disease in a single surgical procedure.  We use principles of conservative radicality and nerve sparing and our target is to remove the disease and cause minimal collateral damage to other pelvic organs, nerves and blood vessels.

Ongoing Care and Patient Support

Harley Street Clinic Endometriosis Centre is a coordinated multidisciplinary network. It offers comprehensive and personalised approach to endometriosis from all aspects.
