Uterus didelphys is one of the congenital malformations of the uterus, which occurs due to incomplete fusion along the midline of Müller’s ducts, resulting in two separate uteri and a vaginal septum. This is a rare congenital abnormality, with a prevalence of 1/1000–1/30 000. Each uterus is connected to one fallopian tube and the ovary. A twin pregnancy with a fetus in each uterus in women with uterus didelphys is an extremely rare phenomenon, with a frequency of about 1/1 000 000. The data available in the literature on the problem of obstetric and perinatal outcomes of multiple pregnancy in women with complete double uterus (uterus didelphys) underwent systems analysis. The authors provide their own extremely rare case of spontaneous pregnancy with two fetuses in separate wombs in uterus didelphys, which has successfully resulted in the simultaneous birth of both fetuses via abdominal delivery, without any complications at 36 weeks of pregnancy. There are very few reports of multiple pregnancy in women with uterus didelphys. The authors give data from the review of foreign literature, as well their own extremely rare case of spontaneous twin pregnancy in a woman with uterus didelphys.
