While becoming a father might be far from the minds of most young men, their current behavior patterns may impact their ability to become a father later in life. A new study identifies excessive laptop use as a leading cause of male infertility.

Kavic recommends placing laptops on desktops to prevent damaging sperm and decreasing counts and motility. Other tips to protect male fertility include:

• Avoiding hot tubs

• Using boxers over briefs

• Avoiding drugs and excessive alcohol use

• Minimizing exposure to toxins

• Avoiding exercise that can generate heat or trauma to the genital area

• Refraining from ejaculating too frequently (the recommendation is to only engage in sexual intercourse every other day around ovulation)

• Exercising moderately (one hour, three to five times per week)

• Eating well

• Taking a daily multivitamin

• Getting eight hours of sleep per night

• Staying hydrated and limiting caffeine to no more than two cups per day

• Refraining from smoking

• Avoiding excessive weight gain or weight loss

• Practicing stress reduction techniques

Other Causes of Male Infertility

Forty percent of fertility issues are attributed to males. Other leading causes of male infertility include varicocoeles or enlarged varicose veins in the scrotum. This condition can raise the temperature in the testicles and damage or kill sperm. Other reasons include genital injuries or defects, certain sexually transmitted infections, prostatitis (an infection or inflammation of the prostate), immune and hormonal disorders and erectile dysfunction. Kavic also notes that underlying health issues and medications may be to blame for fertility issues.

"Medications for depression, blood pressure and certain heart conditions may lower libido or cause impotence," said Kavic. "Men should talk with their physicians to see if medication is necessary or if they can switch to another with fewer side effects."

"With Father's Day around the corner, males should be reminded to take care of their health," said Kavic. "An annual physical exam combined with a healthy lifestyle may make it easier to become a dad when the time is right."
