Human/male genetic biological clock

When parents are over 35 years old, man and woman alike,
the following cases become prevalent:

Up to a third of all cases of schizophrenia are linked to increasing paternal age.
Men 40 and older are nearly six times more likely to have offspring with autism than men under age 30.
Other research shows that the risk of breast and prostate cancer in offspring increases with paternal age.
The chances of parents of babies with achondroplasia is higher
Older fathers can cause genetic conditions in their offspring, such as birth defects, autism and schizophrenia.
