Old sperm dangerous

By Jessica Hamzelou. Older fathers are now known to pass on more genetic mutations to their children than older mothers do. And children of older fathers are more likely to have autism and schizophrenia. Growing evidence suggests that older dads might pass on health risks through epigenetic tags on the DNA in their sperm. These tags alter how active genes are, and lifestyle factors such as diet and smoking are known to make epigenetic changes that may affect the next generation. Ageing is also a factor. Jenkins and his colleagues have studied the sperm of men, looking for these genetic switches.

Worries about aging sperm — or, more accurately, sperm from aging men — are the same as the concerns about aging eggs: decrease in fertility, and increase in genetic problems and psychiatric and behavior disorders among offspring.

I apologise, but, in my opinion, this theme is not so actual.
