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.
