A British woman is believed to be the first in the world with two wombs to give birth to triplets.
Hannah Kersey of Northam in Devon became pregnant in both wombs, the BBC reported. One fertilized egg divided to become identical twins, a type of pregnancy that has a 1-in-25 million chance of occurring.
"There are very few world firsts nowadays but it may be one," said Dr. Simon Grant, who delivered the triplets at Southmead Hospital.
About 1-in-1,000 women in Britain have two wombs, a condition known as uterus didelphys. The condition in some cases appears to be genetic and Kersey's mother and sister both have it.
Only 70 cases of women being pregnant in both wombs simultaneously are known to have occurred.
Kersey and her partner, Mick Faulkner, say the girls are healthy although they were born prematurely and spent nine weeks in the hospital. Kersey said they have different personalities with Grace, who had a womb of her own, more of a leader, Ruby more laid back and Tilly, the smallest at birth, determined to keep up.
