1. Smoking: Smoking releases a large number of harmful substances, which can cause DNA damage to sperm and poison the reproductive system, thereby weakening the ability and quantity of sperm to swim.
2. Drinking: Excessive drinking can reduce testosterone levels in the testicles, damage sperm production and quality, and lead to decreased sperm count and abnormal morphology.
3. Sitting for too long: Sitting for a long time can raise the temperature of the testicles, which can have a serious impact on sperm production and quality, resulting in reduced sperm count, abnormal morphology and reduced motility.
4. External compression: Wearing tight pants, hot water bottles and other behaviors that excessively compress the testicles will cause the temperature of the testicles to rise, thereby affecting the production and quality of sperm, which in turn affects the health of the testicles.
5. Lack of exercise: Insufficient exercise can lead to abnormal metabolism of the body, causing the temperature of the testicles to rise and the impact on reproductive function, thereby affecting the quality and quantity of sperm.
6. Unhealthy diet: A diet high in fat, calories, and a lack of vitamins and minerals can affect the function of the testicles, which in turn affects the number and quality of sperm.
7. Excessive tension: Excessive pressure at work and life can lead to a decrease in male immunity, affecting the normal functioning of the reproductive system, thereby affecting the quantity and quality of sperm.
8. Long-term staying up late: Long-term insomnia or staying up late can lead to physical exhaustion and decreased immunity, which will affect the quality and quantity of sperm.
9. Excessive masturbation: Excessive masturbation can lead to a decrease in sperm count, reduced sperm morphology and motility, which will have a certain impact on male fertility.
10. Environmental pollution: Environmental pollution is also a potential threat to male fertility. Environmental pollution can cause poisoning of the male reproductive system, which in turn affects the quantity and quality of sperm.
