1. Do not have sexual activity too frequently
Excessive frequency of sexual activity can not only lead to impotence but also reduce the amount of sperm in each ejaculation. If there are fewer than 20 million sperm per milliliter of semen, the chances of conception for the female partner are very slim.
2. Do not smoke or drink alcohol
Smoking and excessive drinking are the enemies of sperm. Sperm is quite sensitive to nicotine, a substance in cigarettes that can reduce the secretion of sex hormones and kill sperm. If an adult man smokes 30 cigarettes a day, the survival rate of sperm is only 4%, and the rate of sperm malformation increases. Moreover, long-term and excessive drinking can cause chronic or acute alcoholism, which can lead to 70% of sperm developing abnormally or losing vitality.
3. Do not interrupt nutrition
Some men have monotonous diets and preferential eating habits, and do not like to eat animal products. Over time, this can lead to a decrease in the amount of zinc in the body. A zinc deficiency in men can reduce libido and sexual function, decrease sperm count by about 30%, and even cause men to lose fertility.
4. Avoid too much heat
The scrotum acts as the 'temperature regulator' for the testicles, which should usually be a few degrees lower than body temperature for the testicles to produce sperm smoothly. Men who have the habit of taking hot baths should try to quit. Because hot water can easily raise the temperature of the scrotum, causing a decrease in sperm count, and wearing jeans or tight pants can also cause the scrotum to be difficult to dissipate heat, obstructing the return of venous blood to the scrotal area.
5. Do not be melancholic and sorrowful
Worry,烦恼, and adverse mental states directly affect the function of the nervous and endocrine systems, indirectly affecting sperm quality.
