Maria Tescu, a 33-year-old botanist, gave birth to Valentin at the Cuza hospital in the town of Iasi this week, 59 days after delivering his brother, Catalin.
One in every 50,000 women has a double uterus but doctors believe it is the first time a woman has become simultaneously pregnant then given birth twice within two months. Both were delivered by Caesarean section.
Mrs Tescu said: "I checked into hospital last week to make sure nothing would go wrong. I am happy I have another healthy boy and now I am ready to go home with both of them."
Catalin was kept in hospital because he had weighed just 3lbs 9oz. He now weighs 4lbs 11oz, exactly the same weight as Valentin. Dragos Dragomir, head of the maternity ward, said: "This case is unique, first, because Mrs Tescu has a uterus malformation which has resulted in two separate cavities ... [and second, because] a pregnancy occurred in each uterus.
"Women with a malformation like this cannot usually have babies in both wombs because one is often under-developed."Reuse content
