Woman gives birth after childhood ovary restored

A Congolese-Belgian woman has become the first in the world to give birth to a healthy child after doctors restored her fertility by transplanting ovarian tissue that was removed and frozen when she was a child.

The woman, who was diagnosed with sickle-cell anaemia when she was five and emigrated to Belgium at age 11, needed a bone marrow transplant to treat her sickle-cell condition - a procedure that requires chemotherapy first.
