Woman gives birth to baby boy after uterus transplant in Alabama

A woman born without a uterus welcomed a baby boy, becoming the first person outside of a clinical trial to give birth after receiving a uterus transplant.

The mom, identified by University of Alabama Birmingham Hospital only as Mallory, was 17 when she was diagnosed with Mayer-Rokitansky-Küster-Hauser syndrome, which affects approximately 1 in 4,500 female newborns. She was told she would never be able to biologically carry her own child. 

Years later, Mallory and her husband Nick had a daughter via a surrogate, Mallory's own sister, the hospital said in a Monday news release. They wanted another child, but asking Mallory's sister to undergo another pregnancy would have risked the sister's own health, so the couple began looking into uterine transplant.
