In a world first, a woman rendered infertile by cancer treatment gave birth after one of her immature eggs was matured, frozen, and then – five years later – thawed and fertilised, researchers in France reported.

A study in the journal Annals of Oncology published on Feb 19, 2020, describes how the baby boy was born to a 34-year-old French woman who had been treated with chemotherapy for breast cancer.
