Factors That Increase the Risk of Male Infertility


Do you want to have kids? Avoid these factors that increase the risk of male infertility — such as cycling, certain illnesses, and extra weight.

“In approximately 30% of couples attending for infertility investigations, ‘a male factor’ is thought to be the likely cause of the infertility,” say the experts at Sims International Fertility Clinic in Dublin, Ireland. “In a further 20% of couples, factors in both the man and the woman are thought to be relevant. It is very important therefore for the doctor to evaluate both partners when considering the reasons and the most appropriate treatment for a couples’ infertility.”

Certain illnesses. If you’ve struggled with cancer, cryptorchidism, variococele, physical groin injuries, hydrocele, or the mumps, then you’re at an increased risk of male infertility.

Oligospermia, azoospermia, or asthenozoospermia. Oligospermia occurs when a man produces few sperm; azoospermia is when no sperm are produced. Asthenozoospermia occurs when a man produces a normal number of sperm, but they have poor motility.

Extra weight. A 20 pound increase in a man’s weight can increase the chances of male factor infertility by about 10%, say.

Substance abuse. Drug use (cocaine and marijuana) can temporarily reduce both the number and the quality of sperm…but alcohol doesn’t appear to affect the quality or quantity of sperm.

Free radicals. Oxidants or free radicals are unstable molecules that are released as a by-product of many natural chemical processes in the body. “Infections, chemicals, and other environmental assaults can produce high levels of these particles…Sperm are particularly vulnerable to the damaging effects of this oxidation process.” If you’re trying to get a woman pregnant, eat lots of foods with antioxidants!

Bicycling. The Maryland Medical Center’s doctors say: “Bicycling has been linked to impotence in men and also may affect fertility. Pressure from the bike seat may damage blood vessels and nerves that are responsible for erections. Mountain biking, which involves riding on off-road terrain, exposes the perineum (the region between the scrotum and the anus) to more extreme shocks and vibrations and increases the risk for injuries to the scrotum. One study found that men who mountain bike are far more likely to have scrotal abnormalities, including calcium deposits, cysts, and twisted veins.”
