Uterus didelphys is a rare congenital Müllerian duct anomaly, with an estimated prevalence of 0.5–5% in the general population. It is caused by complete failure of development, fusion, canalisation or resorption of the bilateral Müllerian (paramesonephric) ducts between 6 and 22 weeks in utero. This anomaly leads to the formation of two uteri, two cervices and, in most cases, a double vagina.
