If you are a woman, you are familiar with all the pressures and challenges attached to your reproductive system. Especially in particular, your biological clock and the increasing risks to your health and your childs developmental health the later in life you decide to have kids.
However, I was surprised to learn recently that now they have now discovered a link between older fathers and a risk of Autism and Schizophrenia in children. It has been shown that older men are more likely to have children with autism or schizophrenia than younger ones. This is due to the fact that older fathers pass on significantly more random genetic mutations onto their children increasing the risk of their children having these conditions.
