What affects male fertility?

Opinions about male fertility have circulated for decades.  From Mountain Dew to tight underwear, a number of theories have been passed around.

Fortunately, a new study reports on true factors affecting male fertility.  Over 2,200 men were interviewed for the report.  Here are highlights from the study:

  • Men with low sperm counts were 2.5 times more likely to have had testicular surgery;
  • Low sperm counts were associated with manual labor and being African-American;
  • Wearing boxers was less likely to be associated with sperm motility issues;
  • Smoking, drinking alcohol, recreational drug use, and a high body mass index (BMI) were NOT associated with semen quality.

These results debunk some old theories on male fertility and provide new information regarding true factors leading to infertility.
