Why is the old father easy to give birth to malformed children?

Older men are more likely to give birth to malformed children than younger fathers. Experts at Oxford University (UK) recently learned the reason is the mutant cells in the testes.

Specifically, these are benign testicular tumors with the spermocytic name seminomas. Although these mutant cells are harmless to men, the team believes they can alter germ cells that produce sperm.

This will lead to gene mutations in the DNA of children, resulting in rare growth disorders, such as a lack of cartilage development.

The study, funded by the Wellcome Trust and the Danish Cancer Society, helps explain why some diseases are more common among older children, according to DailyMail .

The lead researcher, Professor Andrew Wilkie from Oxford University, said: " We think that most men who grow old generate tiny mutant cells in the testes. They are like moles. On the skin, it is usually harmless to the owner, but because it is in the testes - where sperm is produced - they cause babies to be born with many different diseases . "

This work balances the view that only women should worry about having children late.
