Alrighty, so here's a pertinent post, based on this article: Male 'Biological Clock' Ticking
First, a story: I had skimmed this article on Tuesday (no, I haven't been slacking as much as ya'll thought) and something came up related to these so-called clocks while walking to deep dish pizza (heavenly, btw). Unfortunately, I sucked in trying to related this story, because I forgot a few pertinent points, such as why it's bad for men to sire children when they're getting up there in years. Except I couldn't remember the word "sire" and I said "spawn" instead, and got made fun for that. Pretty amusing, I agree. I know, bad story.
Back to the article. If a man SIRES children in his 40s, the children tend to score worse on intelligence tests, and there's a higher risk of physical defects AND neuropsychological conditions. Of course, we all know that "old" mothers result in higher risk of children with birth defects, BUT they're kids tend to score better on intelligence tests.
