Twins were delivered by a woman with two uteruses at a Florida hospital last week.
The mother and infants are healthy, according to doctors at Morton Plant Hospital in Clearwater, where they were born.
Nathan was born at 36 weeks and weighed 5 pounds, 8 ounces. His sister emerged two minutes later, weighing 5 pounds, 10 ounces.
Barbosa has a rare condition called uterus didelphys, or double uterus, that affects about one in 2,000 women worldwide.
Uterus didelphys (also uterus didelphis) represents a uterine malformation where the uterus is present as a paired organ, as the embryogenetic fusion of the mullerian ducts failed to occur. As a result, there is a double uterus with two separate cervices, and often a double vagina as well. Each uterus has a single horn linked to the ipsilateral fallopian tube that faces its ovary.
Double uterus develops in the female fetus before birth and occurs when the two tubes that normally fuse together to form the uterus fail to form, developing into two separate cavities.
Generally, the uterus didelphys symptoms are mainly about severe pain during a menstrual cycle and lot of bleeding, which might happen through the periods. The condition of uterus didelphys is usually harmless and the woman can have a safe pregnancy, without any chances of complications.
A didelphis uterus is a rare condition and it has been observed that around 80 percent of the cases of uterus didelphys go through a C-section for successful delivery.
In the United States, uterus didelphys is reported to occur in 0.1 to 0.5 percent of women. Patients with double uterus may need special attention during pregnancy as premature birth and mal-presentation are common.
