Human sperm has for the first
time ever been created entirely in a test tube using tissue from
a sterile man, French scientists said Thursday.
The in vitro sperm was obtained from tissue taken from the
testes.
The technique developed by scientists of Kallistem, a
start-up of the French national research centre, could help
preserve fertility in children having to undergo potentially
dangerous treatments such as chemotherapy.
It could also be used to treat infertility in some cases.
"We hope the first centres will make the technique
available within five years," said Kallistem President Isabelle
Cuoc.
