Certainly the 30% success rate of sperms isn't encouraging, and the fact that viruses, prions, bacteria and nano-bacteria (collectively "germs") are also reanimated isn't encouraging either. But no one can revive a whole person from liquid nitrogen cryopreservation by present day technology. But a future technology capable of reviving a whole person, rather than a collection of a few sperm, is less likely to have these problems. It should also be able to separate out the unwanted stow-aways and exterminate them. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, de Rivaz genealogy, Nomad .. and more > > "Once sperm is frozen in liquid nitrogen, its biological activity ceases, > meaning it doesn't deteriorate.
