What age are men most fertile?

Online Answer
Men younger than 40 have a better chance of fathering a child than those older than 40. The quality of the sperm men produce seems to decline as they get older. Most men make millions of new sperm every day, but men older than 40 have fewer healthy sperm than younger men.
