Male infertility refers to a male's inability to cause pregnancy in a fertile female. In humans it accounts for 40-50% of infertility
Male infertility has many causes--from hormonal imbalances, to physical problems, to psychological and/or behavioral problems. Moreover, fertility reflects a man’s “overall” health. Men who live a healthy lifestyle are more likely to produce healthy sperm. The following list highlights some lifestyle choices that negatively impact male fertility:
Smoking--significantly decreases both sperm count and sperm cell motility.
Prolonged use of marijuana and other recreational drugs.
Chronic alcohol abuse.
Anabolic steroid use--causes testicular 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.
Exposure to environmental hazards and toxins such as pesticides, lead, paint, radiation, radioactive substances, mercury, benzene, boron, and heavy metals Malnutrition and anemia.
