.....this can't be good
Women have the XX chromosome and men have the XY, correct?
If so, that means that only daughters could be born. The more females out number us the more this procedure will be practiced...resulting in even more females until the entire male population will become an endangered species.
QUICK, Men, procreate, procreate like there is no tomarrow because someday there won't be for us. NOW, GO!!!!!
(If it ever advances enough to use in humans of course)
