At 10 years old, Shiloh is approaching puberty, which presents a new set of medical questions. "We're worried about how things are going to evolve as puberty goes along," Dr. Hand says. "We expect it to be okay because she has the ovary, but with all the hormonal changes, we're going to have to see how that goes." Shiloh won't be able to give birth, but her ovary will produce eggs, and she could have a surrogate carry a child for her.
