The CCG service offers care to adolescents and adults with structural differences in how the uterus, vagina and vulva may have formed differently, or did not form, before birth.

Complex congenital gynecology (CCG) conditions can cause pain from obstructed menstruation, can affect sexual function, fertility and routes to parenthood. 
Some conditions may be associated with congenital (from birth) differences in bladder and bowels.  

The multi-disciplinary service includes gynecology, specialist nursing, psychology, urology, and radiology. 

There is an overlap with our DSD service and some patients with CCG conditions may identify as having a DSD condition.  

Please view our welcome pack for new patients: Complex Congenital Gynaecology and Differences of Sex Development.

Menstrual obstruction management
For patients with obstructed menstruation hormonal treatment for endometrial suppression is recommended to manage pain and reduce further obstructed menstrual blood accumulating.

Norethisterone is recommended as first line (note not licensed contraception).

Norethisterone 5mg; orally three times daily continuously (i.e. no break).

Contraindications/cautions:

  • VTE history or thrombophillia
  • Arterial thrombosis risk factors (eg obesity, cardiac disease, migraines)
  • Hepatobiliary conditions

Where contradictions to Norethisterone consider Medroxyprogesterone acetate 10mg two-three times daily

If menstrual obstruction is already well managed with continuous hormonal contraception then this can be continued.

If advice on endometrial suppression is required, please contact the team (uclh.pag.queries@nhs.net)
