Why men should also worry about waiting too long to have kids
The key is that, while women are born with a finite number of eggs, men form new sperm throughout their lives, with the existing sperm replicating its DNA and then splitting into two, over and over again. That might seem like a fountain of youth for men, but it’s actually more like a game of telephone — each time the process is repeated, there’s the chance that the DNA will change a little.
I know about that, I've been studying this stuff for a few years, and it doesn't say a man has a biological clock like women, it says his sperm isn't as good as when he is young, BUT not naturally, its a lifestyle thing. Women DO have a biological clock, and thats because they lose eggs every year. In this day, and age, you have access to all types of healthy food, and exercise equipment, its justt up to YOU to learn the knowledge on what to do, and even then its out there. There is no reason for the average man who is dating women, to not be in good health, so your sperm can be at its best.
As far as dna mutations, again that can be avoided through lifestyle changes. This has been proven.

From the article:
"Unlike women, who are born with a finite number of eggs, men continue to produce sperm throughout their life, and some can father children into their 60s and beyond — an age where women’s clocks have totally stopped ticking. George Lucas, Steve Martin and Rod Stewart all famously fathered children in their late 60s.
But for most men, testosterone declines as they age, which can lead to decreased libido and erectile dysfunction. And as they get older, men also see a decline in the quantity and genetic quality of sperm."
"There’s just no consensus on when men should be considered of an advanced age reproductively," he says. "But the concept is certainly one that we should embrace, in that men are not immune to the effects of aging on their reproductive system."
For men, some of these changes are treatable or avoidable. Men who are overweight are far more likely to experience low testosterone levels. And male fertility problems are often linked with other health problems, including cancer, hypertension, heart disease or kidney disease, Pastuszak says.
There's also growing evidence that what a man eats, drinks and smokes, what pesticides or industrial chemicals he is exposed to, and even how much stress he experiences in the months leading up to conception can influence the health of his sperm, and thus potentially the health of the baby.
