Perhaps it could be advantageous for men to freeze their sperm at a young age, too. There is some evidence that the older the father is at conception, the more likely his child is to have autism. There's also at least one study that suggests that the link can skip a generation: if a man is relatively old when he has a son, then his grandson is more likely to have autism. (That said, conflicting studies exist, and more research is required.) http://en.wikipedia.org/wiki/Paternal_age_effect http://en.wikipedia.org/wiki/Paternal_age_effect http://well.blogs.nytimes.com/2013/03/29/grandfathers-age-linked-to-autism/ http://well.blogs.nytimes.com/2013/03/29/grandfathers-age-li...
