What could be worse than the inability to continue your race and leave offspring? Scientists have identified several causes of infertility that many men do not even know about. What can lead to infertility?
Despite the progress of medicine, the number of cases of male infertility is constantly increasing every year. American experts have selected 8 causes of infertility that many men are unaware of.
1. Steroids
Men who are actively involved in sports often use anabolic steroids. One of the side effects of these drugs is a decrease in the size of the testicles and, as a result, male infertility. Also, "anabolic steroids" disrupt the natural hormonal level of men.
2. Malnutrition and anemia
Lack of beneficial nutrients negatively affects male reproductive health.
3. Tight clothing
Wearing trendy but tight-fitting underpants reduces sperm production due to the excess heat that such underwear generates in the genital area.
4. Excessive physical activity
Of course, sports are good for health, but excessive physical activity can lead to male infertility. They cause the body to produce large amounts of steroid hormones that cause testosterone deficiency.
5. Smoking
A bad habit that significantly reduces sperm count and motility.
6. Drugs
Long-term use of marijuana and other so-called "weak" drugs negatively affects the reproductive health of men.
7. Chronic alcohol abuse
This bad habit affects male fertility even more than smoking.

8. Deficiency of vitamins
Lack of vitamin C and zinc in a man's diet can cause infertility.
