Men of higher intelligence tend to produce better quality sperm, UK research suggests.
A team from the Institute of Psychiatry analysed data from former US soldiers who served during the Vietnam war era.
They found that those who performed better on intelligence tests tended to have more - and more mobile - sperm.
The study, which appears in the journal Intelligence, appears to support the idea that genes underlying intelligence may have other biological effects too.
Therefore, if tiny mutations impair intelligence, they might also harm other characteristics, such as sperm quality.
Conversely, people with robust genes might be blessed with a biological "fitness factor" making them fit, healthy and smart.

I'm not sure what else to add to it so yeah...
