Uterus transplantation has been one of the biggest challenges in the world of medicine. According to a report in the Sunday Express on October 10, 2010, the head of the Department of Obstetrics and Gynecology at the University of Gothenburg in Sweden, Professor Mats Branström, has claimed to have found the secret of successful uterine transplantation in animal studies. Professor Branström claims to have found the secret of successful uterus transplantation and has achieved success in animal experiments. The Swedish scientists first performed uterine transplants on a number of rats, which not only became pregnant through natural mating, but also gave birth to pups. The researchers also performed uterine transplants on sheep and pigs, and the results were quite satisfactory. The scientists at the University of Gothenburg, Sweden, who made this amazing breakthrough in collaboration with researchers from the University of Valencia, Spain, plan to announce their amazing findings to the world at a conference in mid-October 2010. This latest research will be published in the upcoming issue of the Scandinavian Journal of Obstetrics and Gynecology. On September 20, 2012, the world’s first uterus transplant from a mother to her daughter was completed. Experts at the University of Gothenburg performed the procedure last weekend, no complications were found, and now two Swedish women are carrying their mother’s womb. They will have to wait until the women are pregnant to consider the success of the operation. One of the surgeons, Michael Orosen, said the two women were first operated on by a surgeon. Orosen said the women underwent in vitro fertilization before the surgery. After a one-year waiting period, doctors will implant the embryos into their wombs. The embryos were grown after the eggs were fertilized with their spouses’ sperm. The embryos have been frozen while each woman will be allowed only two pregnancies, Oroson said. The wombs will then be removed.
