Turns out women aren't the only ones who have to worry about their biological clocks.

Other risks associated with pregnancy involving an older father include dwarfism, which is the result of genetic mutations passed on through the sperm. Even cancer risks rise as fathers gets older, Men's Health reports.

While the facts are alarming, urologist Robert E. Brannigan says the risks are still low and most older dads go on to father healthy children.
