A Woman’s Uterus Has Been Kept Alive Outside the Body for the First Time

Spanish researchers at the Carlos Simon Foundation have kept a donated human uterus alive outside the body for 24 hours using a normothermic perfusion device called “Mother” (PUPER). The machine circulates oxygenated, nutrient‑rich blood through the organ, mimicking natural circulation. This proof‑of‑concept marks the first time a human uterus has survived a full day ex‑vivo, opening pathways for extended research and transplantation. The team aims to lengthen survival to a full menstrual cycle and eventually explore lab‑based gestation.
