FertilisationUS researchers say they will redouble their efforts to create human sperm from stem cells following the success of a Japanese study involving mice.

A Kyoto University team used mice stem cells to create eggs, which were fertilised to produce baby mice.

Dr Renee Pera, of Stanford University in California, aims to create human sperm to use for reproduction within two years, and eggs within five years.
