The 27-year-old had an ovary removed at age 13, just before she began invasive treatment for sickle cell anaemia. Her remaining ovary failed following the treatment, meaning she would have been unlikely to conceive without the transplant.
Ten years later, she decided she wanted to have a baby, so doctors grafted four of her thawed ovarian fragments onto her remaining ovary and 11 fragments onto other sites in her body. The patient started menstruating spontaneously five months later, and became pregnant naturally at the age of 27.
About 40 babies have already been born across the world using frozen ovarian tissue taken from older women.
