A woman from China’s northwest region has made headlines after giving birth to twins from two separate uteruses, a rare occurrence that has captured the attention of the medical world. The woman, known only by her surname Li, delivered the twins in September at a hospital in Shaanxi province, according to a report by the South China Morning Post (SCMP).

The woman was diagnosed with uterus didelphys, a rare condition that affects only 0.3 per cent of women worldwide. This condition results in a woman having two fully formed uteruses, each with its own set of ovaries and oviducts. While it is already uncommon, Li’s case was even more remarkable because she managed to naturally conceive and give birth to twins—a boy and a girl—each from a different womb.

The twins were born when Li was eight and a half months pregnant, adding a unique chapter to the limited cases of such births across the globe.
