Utah Woman With Double Uterus Having Two Babies


Angie Cromar has known that she has a condition that affects one in 1000 to one in 1 million women worldwide – uterus didelphys, or double uterus. Many women with a double uterus have normal sex lives, pregnancies and deliveries. But Ms. Cromar is having two babies, conceived at different times, something researchers think has only happened about 100 times in modern medical history.

During her first ultrasound, Ms. Cromar’s doctor, Dr. Steve Terry of Murray UT, found that one baby was about five weeks and four days along, while the other was six weeks and one day. The chances of this happening are about five million to one.


In the female fetus, the uterus develops from two small tubes called Mullers ducts. As development occurs, the tubes normally join to create one larger, hollow organ. Sometimes – and researchers don’t know exactly why – the tubes don’t join completely and each one develops into a separate cavity, giving the uterus a heart shape.

In most cases, the two wombs share a set of Fallopian tubes, ovaries, cervix and vagina, but in some cases women have two of everything. Surgery can fuse the two vaginas into one, but the wombs are typically left separate.

Uterine abnormalities occur in as many as 4 percent of women who have normal pregnancies and of these 5% have a double uterus. Some women have the condition and never know it, unless it is diagnosed because of symptoms such as pelvic pain, abnormal bleeding, or repeated miscarriages.

Ms. Cromar, a labor and delivery nurse herself, says that she is nervous, but very excited. Uterus didelphys carries a risk of preterm labor and low birthweight, but she has had normal pregnancies so far and is very positive.
