It took well over a year to determine if a woman who received a womb transplant would become the first in the U.S.to give birth, transplant surgeons in Dallas said Monday.
The procedure at Baylor, however, marks the first time a successful delivery has followed such a procedure in the United States.
The hospital has not revealed many details surrounding the birth, including when the baby boy was born.

"People like me, or men in general, don't really talk about this, because we don't know any better, but one thing that we all learned is that we should never have underestimated the need, the will, the wish, of the woman to carry their own pregnancy", Testa said. Baylor, which launched its womb transplant program past year, has completed eight out of 10 planned uterus transplants.

Crews raced to fix and replace the damaged wires so Friday's Christmas tree lighting could go on as scheduled. Nevermind the Grinch, it was almost a squirrel who stole Christmas in one New Jersey town.
So far, only eight other babies have been born to women who have received uterus transplants, and all of those births occurred in Sweden. There have been at least 16 uterus transplants worldwide, including one in Cleveland from a deceased donor that had to be removed because of complications. The mother, who wishes to remain anonymous, was born without a uterus and underwent the transplant from a living donor a year ago at Baylor University Medical Center in Dallas, TX.
Last month, Penn Medicine in Philadelphia said it would start offering womb transplants. The first four cases involved "altruistic" donors - unrelated and unknown to the recipients.
The women selected for the study had to be healthy with working ovaries. Once a transplant is successful, in vitro fertilization is required to kickstart the pregnancy, as the ovaries are not connected to the transplanted womb. Doctors hope that womb transplants will enable as many as several thousand women born without a uterus to bear children. The wombs are not meant to be permanent.
The doctors who helped deliver the first American baby born from a transplanted uterus opened up about the medical milestone, one of them telling ABC News, "this little boy will stay with us for our entire life". While three have been unsuccessful and one woman is now pregnant, the remaining four women are in different stages of the transplant process, and doctors say the baby offers them hope.
