Livebirth after uterus transplantation from a deceased donor in a recipient with uterine infertility
Comprehensive Overview
This study, published in The Lancet (2018), reports the world's first successful livebirth following a uterus transplant from a deceased donor, a milestone for women born without a uterus or who have lost one to illness or surgery, a condition known as absolute uterine infertility that affects roughly 1 in 500 women. Until this point, the only proven path to childbirth through uterus transplantation had involved living donors, typically family members or close friends willing to undergo major surgery to donate their uterus, a requirement that severely limits how many women can access this option. A previous attempt using a deceased donor, performed in Turkey years earlier, had achieved pregnancy but ended in miscarriage, leaving real uncertainty about whether a uterus removed from someone who has died could remain viable long enough to support a pregnancy. In this case, surgeons in Brazil transplanted a uterus from a 45-year-old deceased donor into a 32-year-old woman with a congenital condition causing absence of the uterus. After the recipient's body accepted the new organ without signs of rejection, doctors transferred a single embryo, created earlier through in-vitro fertilization, into the transplanted uterus.
Outcomes and Implications
The most notable finding was that the pregnancy proceeded normally to near-term, resulting in a healthy baby girl delivered by cesarean section at just under 36 weeks, with excellent health scores at birth and normal growth continuing many months later, confirming that a transplanted uterus from a deceased donor can fully support a healthy pregnancy from conception through delivery. Throughout the pregnancy, ultrasound monitoring showed normal blood flow to the uterus and normal fetal growth, and regular biopsies of the transplanted tissue showed no signs the recipient's immune system was rejecting the organ. Notably, the transplanted uterus tolerated roughly 8 hours without blood flow during the transplant procedure before being successfully implanted, more than double the longest such interval previously documented in a successful living-donor transplant, suggesting these organs may be more resilient to this kind of stress than previously assumed. The transplanted uterus was removed during the same surgery as the delivery, and the mother's immune-suppressing medications, needed to prevent organ rejection, were then safely discontinued. This matters enormously because it means women no longer need to rely on a living family member or friend willing to undergo donor surgery, dramatically expanding the pool of potential donors to anyone who chooses to donate organs after death. The authors conclude that this result establishes proof-of-concept that deceased-donor uterus transplantation is a viable path to pregnancy, offering a meaningful new option for women who previously had only adoption or surrogacy available.
