News Desk: The age of the mother is considered important for the birth of a child. But no, in this case the age of men is equally important. If men are not fathers at the right age, that effect also falls on the unborn child. Experts say that even autism is one of the reasons for the birth of a child. Men have no age to be a father, researchers suggest. According to them, the number and quality of sperm in men decreases with age. Children of men who become fathers at an older age are more likely to suffer from neurodevelopmental disorders. Again, after 40 years, many are not able to be a father. A 2010 study found that children of men over the age of 40 have a higher risk of developing autism spectrum disorder. The same thing happened in a study published in the Journal of Epidemiology and Community Health. According to the study, boys over the age of 40 and under the age of 25 have worse health consequences if they become parents. It could also be the cause of their untimely death. In that study, researchers suggest that the best time to be a parent is between the ages of 30 and 40. This reduces men's health risks and prevents premature death. Researchers have also suggested that men be fathers. According to them, the quality of sperm depends on daily life. Those who regularly smoke and drink alcohol also lose their sperm capacity, quantity and motility. In this case, researchers have suggested eating healthy food. This will increase sperm production and improve quality. It is also advisable to pay special attention to clothing and movement. Researchers also say that people should pay attention to not sitting for long periods of time, not spending too much time in hot weather and wearing less slim fit clothes.
