Muscle Shoals, AL – A 24 year old Muscle Shoals woman recently underwent the first known ovary transplant in the United States. Now, Stephanie Yarber is pregnant. Yarber received an ovary from her twin sister Melanie Morgan of Tuscumbia during an April operation in St. Louis. Yarber recently confirmed her pregnancy with a home test and a blood test from a physician. Doctor Michael Steinkampf, head of the fertility clinic at UAB Hospital, says ovarian transplants require the donor and recipient to have matching DNA.
