Mom With Two Uteruses Has Twins One from the left uterus, one from the right By John Johnson, Newser Staff Posted Sep 20, 2011 5:33 PM CDT 10 comments Comments A file photo of twins. (Shutterstock) (Newser) – A woman in Florida has pulled off what her obstetrician figures to be a 1-in-5-million longshot by giving birth to twins, reports the St. Petersburg Times. Why the long odds? Andreea Barbosa has a rare condition called uterus didelphys, meaning she has not one uterus but two. That in itself can cause infertility, but Barbosa not only became pregnant, she did so in her separate uteruses at the same time. Twins Nathan and Natalie, along with mom, are doing fine. "It was definitely a shocker," says the 24-year-old mom. "I was frightened and scared—a little bit of everything in one."
