Two commonly used drugs can affect male fertility:

 Marijuana lowers testosterone levels in males, which isn’t good in the baby-making biz because testosterone is the male hormone responsible for male sexual functioning and sperm production. Sperm counts are lower and sperm are less motile in men who use marijuana regularly.

  Anabolic steroids suppress testosterone production and can cause irreversible damage to the sperm production line. Avoid them at all costs.
