Do men have a biological clock?

Do men have a biological clock?
Is Your Sperm Too Old?Turns out that it’s not just women who have a biological clock.While you've never been against the idea of a serious relationship, you are in no particular rush to become a schlub. The attendant trappings of new fatherhood—the preschool viewings, the sleepless nights, the humiliation of carrying a diaper bag—aren't exactly calling out to you the way, say, another night slinging Pisco sours would. The ever-intensifying din of the proverbial biological clock? That's for the opposite sex to worry about—you know, like periods, frizz and whether Mr. Big will dump "Carrie in the Sex and the City" sequel. As far as you know, your little swim team of DNA carriers will be competing at Olympic level into Letterman age. So what's the rush?"I always thought my biological clock was the 36 hours I had left after I took my Cialis pill," says Zack, a 30-year-old producer in Los Angeles. "That's the only clock I've ever felt ticking." Turns out, Zack might want to consider the unsung glories of fatherhood.According to a study released last March in the Public Library of Science Medicine, children born to fathers who were 20 scored an average of 2 points higher on an IQ test than children born to 50-year-old fathers. And that's not all. Recent studies from Israel, California and Sweden have connected "late paternal age" with any number of serious medical conditions: The longer you wait, the more likely it is that your kid will be affected by schizophrenia, dwarfism, bipolar disorder, autism, Marfan syndrome, certain childhood cancers, or even, later in life, Alzheimer's. In some cases, the risk factors skyrocket. A 2005 study conducted by the University of California, Los Angeles, found a fourfold rise in Down syndrome among babies born to men 50 and older. Worse still, those risk factors aren't limited to your tweed-sporting years: Statistically, "late paternal age" starts at 30, as in Zack's age. A 2006 study conducted by Mount Sinai School of Medicine found that fathers in their 30s have children with about 1.5 times the risk of developing autism compared with fathers in their teens and 20s. That factor jumps to five times for dads in their 40s. The cherry on the cake? The American Society for Reproductive
The 'andropause' idea is probably just a way for private doctors to make a quick buck out of prescribing testosterone to middle aged men. But yeah everything wears out as you get older, including sperm quality.
Having children is best left up to young adults. Not 40 somethings. I always laugh when I hear about the corporate douchebag worrying about her biological clock ticking away. But my priorities differ, I chose a family instead of a cubicle or irrelevant business.
NO.Men have been known to father into their 70's.Easily.Funny thing is, we really do not need more babies on planet earth.We're pushing 7 billion." Be fruitful and multiply"But, come on.Enough's enough.Mother earth is screaming bloody rape
no, women have it thats why they want to grubb as much money from men before they become ugly and saggy and wrinkley.
Yes and no. Men are not born with a limited number of a few hundred thousand sperm that they must use up before the age of 45 like women do with their eggs. Men are constantly making new sperm and they have an endless supply of it too. The problem with men's fertility is that as they age, the quality of their sperm decreases, as every cell in your body ages, so do your sperm. A significant number of men have such a low sperm count as they age that they become nearly sterile or completely sterile. And it's not like 70 year old men can easily get women pregnant, their sperm is very slow and weak and the DNA is damaged. Even a 40 year old man has more damaged DNA in his sperm than a 30 year old man, and a 20 year old man has the highest quality sperm of all. By age 50 men have a high risk of fathering children with autism, schizophrenia, bipolar disorder and other disorders/conditions.There is also a problem with pollutants and chemicals in our enviornment that is causing record levels of infertility in otherwise healthy young people of childbearing age. Pollutants are causing a feminizing effect on men, and scientists are predicting that many baby boys born today will be sterile as adults. Many species of animals are also predicted to go extinct in the coming years due to the feminizing of the males, and the low birth rates of males.
