Last year the Hospital das Clínicas at the University of São Paulo School of Medicine in Brazil welcomed the first ever baby born out of a transplanted uterus from a deceased donor.

The 32 year-old recipient who was born with Mayer-Rokitansky-Küster-Hauser syndrome, a condition characterized by the presence of underdeveloped reproductive organs or total absence of one, received the donated uterus in 2016.

The surgery lasted 10 hours and involved connecting the woman’s veins, arteries, vaginal canal, and ligaments to the donated uterus.

The donor was a 45 year old woman who died of a stroke and was deemed a good candidate based on a number of factors.

Five months after receiving the uterus, the patient experienced her first menstruation and after seven months, doctors carefully implanted her uterus with a fertilized egg (they have previously stored from the woman’s invitro fertilization procedure she went thru before the transplant).

The woman went on to have a normal, issue-free, pregnancy, and on December 15, 2017 gave birth to a 6-pound baby girl via C-section. Doctors also had to remove the donated uterus after birth so the mother can stop taking immunosuppressive drugs (taken so she won’t reject the donated organ).

The baby will be celebrating her first birthday in a few days. She is the first baby born from a donated uterus in Latin America and the first in the world from a uterus of a deceased donor.

It is important to note that uterus transplant has been happening since 2012. In a landmark study, Swedish doctor Mats Brannstrom lead the first ever uterus transplant involving nine patients. Out of nine patients, five went on to have babies with the transplanted uterus.

Just last year the US welcomed the first baby born from a transplanted uterus.

Although previous births were from uterus donated by live donors (mostly friends and family of recepients), the baby born in Sao Paolo last year was the first to be born from a uterus of a deceased donor.
