Yes and no: Kathryn, A man's sperm is capable of fertilizing an egg for their entire life. That being said, recent evidence suggests that motility and sperm count do tend to decrease over time. Hope this helps!

Age issues: Yes a male can conceive normal kids well past their sixties and the proportion that would be normal is considerably higher than females.Males produce sperm from stem cells continuously & only the healthiest swimmers get through to fertilize an egg.(natural selection) All a women's eggs are there from birth & accumulate age related injury.That said there is some male age effect,just not as dramatic
