Never mind, the planet is not in peril. We will soon be reproducing without any need for sperm.
This isn't just an unlikely sci-fi scenario. This could be reality, according to Bryan Sykes, an eminent professor of genetics at Oxford University and author of "Adam's Curse: A Future Without Men."
"The Y chromosome is deteriorating and will, in my belief, disappear," Sykes told me.
"Every generation one percent of men will have a mutation which reduces their fertility by 10 percent," explained Sykes. Unlike most chromosomes, the Y does not travel through the generation in pairs, so can never repair itself from a mirror. Flaws are never repaired. "So if that goes on for generation after generation," Sykes argued, "eventually there are no functioning Y chromosomes left."
Plenty of people are working on Parthenogenesis.
