The world's oldest new dad, who, at the reported age of 96, just fathered a baby boy in India, says he's done having kids. But if he wanted to break his record again in a couple years, would biology allow it? Though sperm production does usually keep up until a man's dying day, it's a misconception that "biological clocks" are only of concern to women. The effects of aging on fertility have been studied far less in men than in women, but research shows that both volume and quality of semen generally fall off as a man gets older. A study published in the American Journal of Obstetrics and Gynecology found that, among a sample of couples using in vitro fertilization, every additional year of a man's age corresponded to an percent increase in the odds that a couple would not achieve a pregnancy. A growing body of research also shows that, like women, men's chances of fathering children who have genetic abnormalities increase as they age. Random mutations in a man's sperm pile up as time goes on, and passing on more genetic mutations to a child can increase his or her odds of developing autism, schizophrenia and other diseases, according to a recent study published in the journal Nature.

Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes GAH-meetz , are involved.

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract. Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle. Extreme temperatures, smoking, drug use, and poor diet can all impact the quality of sperm.
