Stacy sent in the most incredible story - at 25 she was diagnosed with premature ovarian failure & her FSH was over 100. She was told she would never be able to have children of her own. Fortunately, Stacy had a trick up her sleeve. She is an identical twin, so she asked her sister to donate eggs & went through IVF with the eggs that would hopefully give her and her husband children that, genetically, would be identical to those she should have been able to have naturally. But the IVF failed & Stacy and her sister were devastated, until they heard about ovarian tissue transplants.
Ovarian transplant is currently only available to identical twins and as far as I can tell, it's only being done at St. Luke's Hospital in St. Louis, Missouri. The most famous case is of Stephanie Yarber, who is the first woman to have delivered a baby after ovarian transplant (includes a video of the doctor who delivered the baby), but since then, at least 4 others have delivered healthy babies.
