But how about men?
Emerging scientific data demonstrate that advanced paternal age exists and is associated with fertility problems. Advanced paternal age is associated with an increase in sperm DNA damage. Advanced paternal age is associated with increase incidence of certain both defects (though this is still rare). Advanced paternal age is associated with an impaired ability of a sperm to fertilize an egg, lower success rates with in vitro fertilization, and lower success rates with ICSI.
