The Optimal Age Range for Men to Become Fathers: Unveiling the Male Reproductive Biological Clock

January 21, 2024

Although men have a longer fertility lifespan compared to women, there is still an optimal age range from a eugenics perspective.

Taking sperm quality as an example, although the sperm of older men does not age and has a higher density, there is a noticeable decline in motility. The number of immobile and deformed sperm increases by 20%, and the metabolism of sperm slows down, leading to the production of waste products. The detrimental effects on offspring can be imagined.

In addition, testosterone levels in men start to decline after the age of 35, with a 1% decrease in secretion per year.

Therefore, just like women, men also have a reproductive biological clock, although it is more flexible.

According to the patterns of the male reproductive biological clock, when is the best time for men to become fathers? Research has found that children born to fathers between the ages of 30-35 score the highest on intelligence tests.

Therefore, the conclusion is that men between the ages of 30-35 have the most robust sperm and are most suitable for reproduction.
