Many types of male infertility aren’t preventable. However, you can avoid some known causes of male infertility:
- Don’t smoke.
- Limit or abstain from alcohol.
- Steer clear of illegal drugs.
- Keep the weight off.
- Don’t get a vasectomy.
- Avoid the heat.
- Reduce stress.
- Avoid exposure to pesticides, heavy metals and other toxins.
Though the risk isn’t conclusive, if you’re an avid cyclist, consider using a gel saddle and a full-suspension bicycle. It may also help to avoid wearing very tightfitting clothing for long periods of time.
