healthy sperm. The following list highlights some
lifestyle choices that negatively impact male
fertility. Note that it is not all-inclusive:

count and sperm cell motility.
Prolonged use of marijuana and other
recreational drugs.
Chronic alcohol abuse.

shrinkage and infertility.
Overly intense exercise–produces high levels
of adrenal steroid hormones which cause a
testosterone deficiency resulting in infertility.
Inadequate vitamin C and Zinc in the diet.
Tight underwear–increases scrotal
temperature which results in decreased
sperm production.
