A host of lifestyle factors can be perilous to your potency. The good news is, once you become aware of these often hidden fertility drainers, they are fairly easy to avoid. Hot tubs, saunas and tight-fitting clothes. Testicles function best when they keep their cool. Steamy spa equipment, snug jeans, synthetic shorts and bikini underwear can all overheat your testicles and inhibit sperm production.
Impotence can be an unexpected and frightening side effect of avid cycling.
A study from the University of Southern California School of Medicine found that a bicycle seat's steady pressure on the groin area can damage arteries and nerves. To avoid this problem, periodically lift yourself off the seat when riding long distances. See a doctor if you feel any numbness or pain, or have erection problems after biking. The danger here is traumatic injury to the genitals, which can hurt your ability to produce sperm or ejaculate. Studies from the Department of Physiology at the Medical College of Ohio show that even minimal stress can cause a man's testosterone levels and sperm count to drop.
