Many people think that men’s age is never a barrier when it comes to having children.You might get the impression that age only matters in female fertility. But this idea is completely wrong. While the change in fertility is more drastic in women, men have biological clocks, too.

According to experts, sperm motility changed with age. An ideal age for fatherhood is 25 to 30 years for men. However, it is also true that men aged 50 years and above are also capable of fathering children.

In 2012, proud dad Ramjit Raghav made global headlines when he became a father at the age of 96. He had beaten the record for the world’s oldest dad – a record he’d set himself, two years earlier, at the age of 94.

However, various studies have shown that after the age of 40, the ability to bear children also decreases in men.

The scientists reported that older men are not only at risk for infertility. They are also more likely to pass on genetic problems to their children. A combination of female age and male age can further increase the risk of birth defects. Take for example the risk of Down syndrome. In women, the risk of having a child with Down syndrome increases with age.

In a study of just over 3,000 children, researchers found that when a woman was age 35 or older, a man’s age mattered more. This was especially true if the woman was age 40 or older. In this group, 50% of the children with Down syndrome received that genetic defect on their paternal side.

In women there is no chance of conceiving after menopause. However, the process of making sperm in the body of boys never stops. But that doesn't mean they don’t have a biological clock'like women. As men age, their sperm undergo genetic mutations. 

As a result, the risk of sperm DNA damage increases. Male fertility is affected. Not only this, if she gives birth at that age, the health of the child may also be adversely affected. In this case, the risk of children suffering from nervous system diseases increases.

Lifestyle irregularities increase the risk of male infertility with increasing age. Unhealthy eating habits, smoking, drinking, stress, various drugs, obesity – are most responsible for male infertility.
