In October 2014, it was announced that, for the first time, a healthy baby had been born to a uterine transplant recipient, at an undisclosed location in Sweden. The British medical journal "The Lancet" reported that the baby boy had been born in September, weighing 1.8 kg (3.9 lb) and that the father had said his son was "amazing". The baby had been delivered prematurely at about 32 weeks, by cesarean section, after the mother had developed pre-eclampsia. The Swedish woman, aged 36, had received a uterus in 2013, from a live 61-year-old donor, in an operation led by Dr. Brännström, Professor of Obstetrics and Gynaecology at the University of Gothenburg. The woman had healthy ovaries but was born without a uterus, a condition that affects about one in 4,500 women. The procedure used an embryo from a laboratory, created using the woman's ovum and her husband's sperm, which was then implanted into the transplanted uterus. The uterus may have been damaged in the course of the caesarian delivery and it may or may not be suitable for future pregnancies. A regimen of triple immuno-suppression was used with tacrolimus, azathioprine, and corticosteroids. Three mild rejection episodes occurred, one during the pregnancy, but were all successfully suppressed with medication. Some other women were also reported to be pregnant at that time using transplanted uteri. The unnamed mother, who received a donated womb from a friend, said that she hoped the treatment would be refined to help others in the future.
