Because in reality, it seems that the age of men has little to do with fertility. Many men are still fertile until the age of sixty or seventy, and some people believe that having children in old age is such a great joy in their family! In fact, the age of men is also closely related to eugenics.
The greater the age, the greater the chance of sperm mutation. In recent years, with the progress of medical research, it has been found that the older the husband is, the more likely he is to have sperm mutations, and the corresponding increase in the chances of genetic diseases in the next generation.
Some studies have found that the risk of deformities increases by 20% when men give birth over the age of 40 compared to children born to men younger than 40. The proportion of mental retardation in the next generation increases sharply when the husband is over 55 years old. A 60 year old man's wife is 10 times more likely to have a fetus with achondroplasia than a 30 year old man.
Many chromosomal aberrations are associated with fathers being too old to give birth. The age of a man can affect a woman's pregnancy success rate, but to their surprise, it can even affect her miscarriage probability. Research shows that when a man is over 40 years old, the probability of miscarriage for a woman is about 35%; The probability of miscarriage for a woman is about 10% to 15% when the man is less than 30 years old.
This is actually easy to understand. Men in their prime of life are in the best state of their body, and their sperm quality is also the best. As men age, their sperm count and quality will decrease. Therefore, from the perspective of eugenics, the age of men should not be too late.
