Age and men’s fertility: At what age do men stop being fertile?

Men’s age significantly affects men’s fertility and semen quality.

Although sperm production continues at older ages, sperm quantity and quality decline after the age of 35. From the age of 45, sperm may begin to show genetic changes, challenging the belief that men can procreate indefinitely.

Odds of getting pregnant with a man who’s over 40 years old

According to some studies, the probability of natural conception decreases after the age of 40 in men, although it is still possible to conceive.

This decline not only reduces the chances of natural conception, but also increases the risk of genetic abnormalities in their offspring.

However, it is important to note that men’s fertility can vary widely from one person to another, and some men can successfully conceive after the age of 40, while others may experience difficulties.
