MEN and women who can’t produce sperm or eggs could one day have “natural”
children of their own thanks to a form of cloning.
Gianpiero Palermo of Cornell University in New York has created artificial
human eggs that contains just one set of a would-be mother’s chromosomes. Such
eggs could be fertilised with the partner’s sperm, just like a normal egg.
And in Australia, Orly Lacham-Kaplan of Monash University in Melbourne has
shown that you can fertilise eggs, not with sperm, but with cells taken from
elsewhere in the body. But there are still considerable obstacles to overcome
before either…
