The male genitals are the only major organ in the human body that is placed outside the protection of the skeletal structure. This evolutionary quirk must work or the species would have become a victim of Darwinian extinction long ago.
But modern life’s activities frequently place strains on the genitals that can be extremely painful or even threatening to your reproductive health. In other words, your body really isn’t designed for marathon running, being whacked by a lacrosse stick, or ballet 5th position.
Urologists theorize that many male sterility problems stem from long forgotten minor incidents in the youth and teen years. Clanging, banging, and strains can be minimized by wearing the right support garment when participating in strenuous activities like sports and dance.
