(Pic:Howstuffworks)A woman usually has a uterus. Even if having twins, then these babies will grow at a the same womb. But what if there are two womb woman?

Experienced an event like the British woman who gave birth to three babies from two womb. Uterus didelphys, or double uterus is a very rare condition. This happened at one of 1,000 to one of 1 million women around the world. Even fewer women who have more than one baby in the womb.

In some cases a double uterus, uterus occurs because the two were sharing a set of Fallopian tubes, ovaries, cervix and vagina. But there is also the case of a woman's womb was born with two, two sets of Fallopian tubes and ovaries, two cervix and two vagina.

Woman with two vagina can perform an operation to combine the two into a single vagina, but not to the uterus. Uterus didelphys is usually occurs when the Mullerian ducts of the developing fetus is never merged into the womb, as they should.

December 2006 in England, three babies were born from the womb of a woman two. The medical knowledge, only about 70 women who were pregnant uterus didelphys with a baby in each womb. This possibility occurs 1 in 5 million women, as reported by HowStuffWorks.

Even fewer women who have more than one baby in the womb. The possibility of women with two pregnant uterus three infants, with two babies in one uterus and one other baby in the womb. This is only one among about 25 million. Hannah Jersey and probably the only one.

Three babies Jersey born 7 weeks early through faults and require surgery in the hospital for two months to complete its development. In December 2006 the third baby came home with a healthy state.

This disorder can cause fertility problems, because the size of the uterus each only half the normal size. This causes problems to conceive, let alone with two or three babies. Women who become pregnant in her womb at the same second, will give birth to 30 weeks earlier than usual, making the baby was born prematurely.

Delivery usually through the process of delivery, before each uterus become so narrow that a baby could not continue its growth. In most cases, the uterus can not stretch long enough like most of her pregnancy.

This type of pregnancy is very different to conceive twins in a womb. In the case of twin pregnancy in two of the uterus, the mother could determine the day of birth of each of her womb, week or month from the uterus completely separate.

However, it can cause problems, because the method that allows a premature delivery. Few obstetricians will perform the surgery twice a month. So at least if one baby will be born by Cesarean section, the doctor usually will recommend another baby at the same time.

The result, in this case is like having twins. The mother in the hospital and eventually came home with two babies the same age.

According to BBC News, a woman in Brazil with a double uterus gave birth to two healthy babies. One infant was born from one womb and a baby in the next 2002 to 2003. China's Xinhua news agency also reported a similar case in China.

With medical technology advances, the possibility of successful pregnancy babies simultaneously in two uterus may be better.
