6 Things To Know About Uterus Transplants In The U.S.

Ten before, in Sweden. In a study done there, nine women received uterus transplants, five became pregnant, and four have given birth so far.

However, unlike the study in Sweden, in which patients received uteruses that were donated by living relatives, the study at the Cleveland Clinic will use deceased donors. Using organs from deceased donors avoids having a living donor take on the risks of uterine removal surgery. Injuries can occur when surgeons try to remove blood vessels that surround the organ, according to the New York Times.

Because of the tricky work that is needed to avoid cutting blood vessels, an operation on a live donor takes between seven to 11 hours, the Times said. The uterus can be removed from a deceased donor much faster. [The 9 Most Interesting Transplants]

Instead, the women will need to undergo in vitro fertilization, in which eggs are removed from their ovaries and fertilized in a lab dish, and implanted in the uterus. The doctors who are conducting the study will not begin the search for a uterus donor for a woman until she has undergone IVF, and has frozen embryos.

If all goes well and the women become pregnant, they will need to have a cesarean section, so that the transplanted uterus will not go through the trauma —> Read More
