Birth of monkey could help ensure boys with cancer can have families

Study involving reimplanting testicular tissue later in life hailed as breakthrough

Testicular tissue taken from young monkeys, which is then frozen and grafted back into their bodies later in their life, can give rise to sperm and allow them to father live young, scientists have revealed.

While the approach has previously been successful in other animals, including mice, it is the first time a primate has produced offspring from the procedure. The team report the baby rhesus macaque that was born is a healthy female that has been named Grady, after "graft-derived" and "baby".
