Human Uterus Preserved Outside Body: A New Frontier in Fertility Medicine

Researchers at the Carlos Simon Foundation have kept a donated human uterus alive outside the body for the first time using the PUPER device, a pivotal advancement that could reshape fertility medicine. By studying living uteruses in a controlled laboratory setting, scientists can now closely observe the implantation process—the critical moment when embryos attach to the uterine lining, which is currently the leading cause of IVF failure. This breakthrough not only offers pathways to improve IVF success rates but also opens the possibility of eventually developing artificial womb technology for fetal gestation.
