Annie was born with two vaginas. Her boyfriends have ‘one each’.

While the condition is known to be extremely rare, numbers on its frequency are still not very clear, with the American Medical Association estimating that just 0.1 to 0.5 per cent of the female population are affected.

Notably, in 2013, American model and beauty vlogger Cassandra Bankson told fans she also suffered from the rare congenital condition, taking to her YouTube channel to answer people’s questions. She also spoke about her experience and the effect it had had on her life on ITV’s This Morning show.

What is uterus didelphys?

Uterus didelphys (double uterus) is a rare condition that occurs in approximately one in 3000 women, according to gynaecologist and fertility expert Dr Sonya Jessup.

Dr Jessup previously told Mamamia the condition describes an uncommon abnormality of the uterus and sometimes also the cervix and vagina.

“In a female foetus, the uterus develops when two mullerin ducts (two parallel tubes) fuse and the middle portion disappears to create a uterus. With this process women end up with one uterus, one cervix, one vagina and two ovaries.

“In some women this process fails to happen in the usual manner. There are many different variations of uterine abnormality ranging from a heart shaped uterus to a situation where a woman may have two uteri, two cervices, and a double vagina.”

According to Dr Jessup, uterus didelphys can usually be diagnosed by an ultrasound or speculum examination and often women will not recognise any abnormalities until they begin menstruation or become sexually active.
