Want to live longer? Get an ovary transplant.

Doctors think they may have inadvertently stumbled on a way to help women live longer while trying to preserve their fertility before having cancer treatment.

At the moment, ovarian transplants are done to preserve the woman's fertility after cancer treatment or to extend her reproductive lifespan, according to one of the researchers, Dr Norika Kagawa at the Kato Ladies Clinic in Tokyo. 

However, more research is needed as none of the women who have received ovarian transplants have yet reached old age.
