“The first modern attempt at transferring a uterus from one human to another occurred at the turn of the millennium. But surgeons had to remove the organ, which had become necrotic, 99 days later. The first successful transplant was performed in 2011 — but even then, the recipient wasn’t immediately able to get pregnant and deliver a baby. It took three more years for the first person in the world with a transplanted uterus to give birth. 

More than 70 such babies have been born globally in the decade since.”
