Although a man's fertility declines as they age a man can still produce sperm that is fertile throughout their lives no matter their age.
Just being older in age does not mean you won't get a woman pregnant so if you don't plan to have a baby and want to have sex you should still use condoms.
Sperm quality also does decline as you age and into your 70s and older men are much more likely to pass on genetic disorders to their children.
A decline in the man's testosterone levels can also impact the mans fertility through sexual dysfunction including erectile dysfunction.
If you're an older man you should have your semen analyzed to make sure everything is normal and have your doctor review any medications you take.
There have been men in their 80s and 90s who've gotten women in their 80s and 90s pregnant as well.
