A Time Warp Baby?, Thats what I would call them.
Senior UK enbryologist Greg Horne helped the unamed man, who had testicular cancer aged 17, to have a baby with his wife 21 years on.
Sperm was frozen at -196C at St Mary's Hospital in Manchester, 21 years ago, and later thawed for the couple, for use in fertility treatment.
Dr Horne stated that the Sperm were particularly mobile and healthy, prehaps a result of a lesser chemical pollution than today?
He stated that "there has been research to suggest that Sperm, even eggs, could survive for 5,000 or 6,000 years, stored in liquid nitrogen. The only thing that might affect it would be background radiation, it would take that long to degrade it"

**Thoughts
What wonderful news. It would seem to beat present day methods of cloning.
Already a world Record I bet this method will become very popular.
How about leaving Sperm and Eggs in ones will, for ones decendants to revive, in 100 years or so?
How about checking frozen animal/human bodies in the Antartic for sperm?
It all sounds distinctly possible, even popular?
