Do you know your sperm count?

The average sperm count is between 120 and 350 million per cubic centimeter. A low sperm count is below 40 million per cubic centimeter. Low sperm counts or poor sperm motility may be due to environmental toxins such as chemicals, radiation, drugs, heavy metal exposure, cigarette smoking, excessive alcohol use, street drug use and pollution. Heat can also reduce sperm production. Hot baths, sitting for long periods of time and tight-fitting underwear that constricts the testes can all elevate temperatures long enough to suppress sperm production.
