There is no set time period when a man’s sperm production stops. Women are born with all the eggs they will ever have. Men, on the other hand, are able to produce sperm cells for their entire lives.
As men age, testosterone levels go down and for some, it might be hard to get an erection. Many men experience erectile dysfunction after age 40. But this is a general slowing––not stopping––of male fertility. We know this because there are many older fathers. Men over age 60 commonly have children.
The oldest father to naturally conceive was reported to be a 96-year-old man from India. Fathering a child after age 90 is rare (even for the record books), but it shows that it’s possible for older men to impregnate someone. That said, men still have biological clocks that cause sperm health and fertility to decline over time (Bhasin, 2022).
When do men stop producing sperm?
