Nowadays, the number of male infertility is increasing year by year, and there are various causes of infertility. Studies have proven that poor lifestyle habits are to blame for the symptoms of oligospermia, weak sperm and dead sperm in some men. What factors lead to male infertility? 1, long-term wearing tight jeans: long-term wearing tight pants on the male scrotum and testicles to form a fetter, coupled with jeans cloth breathability is poor, poor local heat dissipation, causing the scrotum temperature to rise, will reduce the sperm production and vitality. In addition, these pants hinder the local blood circulation of the testicles, especially not conducive to venous blood flow, which can cause testicular stasis and affect sperm production. 2, bath water temperature is too high: high temperature is the “nemesis” of sperm, sperm growth process needs low temperature, otherwise it will be aborted. If male friends often take hot baths, hot springs, saunas, water temperature is too high will reduce the number of sperm or deformed. 3, chemical pollution: long-term work and living in places subject to chemical pollution, such as newly renovated houses, chemical production plants, etc., certain organic compounds in the room can significantly reduce the number of male sperm, and in severe cases, even lead to infertility. 4, long-term smoking: the harmful components of tobacco can enter the reproductive system through the blood circulation, directly or indirectly, toxic effects on various indicators of semen have a negative impact, especially the percentage of forward motion of sperm and sperm morphology. Because of the nicotine and other alkaloids in tobacco, cadmium and smoking-induced oxidative damage, sperm cells increased susceptibility to damage and reduced self-repair ability and other factors, men smoking may also cause sperm aberrations. 5, often social: successful career men always have a lot of social, each social will drink a lot of alcohol, eating spicy food. These two entrances food will damage the hypothalamus – pituitary – gonadal reproductive axis endocrine function, inhibit the synthesis of testosterone mesenchymal cells, damage the spermatogenic epithelium, so that testicular dysplasia, spermatogenic disorders, directly causing sperm morphological changes. Alcohol causes lower testosterone, elevated follicle-stimulating hormone, luteinizing hormone and estradiol, resulting in reduced semen volume, sperm count and reduced sperm motility, etc. How can Chinese medicine prevent and treat male infertility? For male infertility, the three methods of “regulating sperm, treating sperm, and nourishing sperm” are used clinically to regulate the treatment. “To regulate sperm” means to adjust the balance of yin and yang when men have symptoms such as weakness, back pain, night sweats, etc., but the semen examination is normal. ”The treatment of spermatozoa is based on nourishing Yin and tonifying Yang, benefiting the kidneys and filling the spermatozoa, and the prescription of “Liu Wu Sheng Jing Tang” and a series of empirical prescriptions. The commonly used herbs include Fructus Lycii, Rhizoma Polygonati, Radix Achyranthes Bidentata, Radix Achyranthes Bidentata, Rhizoma Polygonati, Rhizoma Cistanches, Radix Cyperus, Semen Cuscutae, etc. The “sperm maintenance” means that after the sperm has reached the standard, the medicine should not be stopped suddenly, so that the sperm quality will not plummet and the previous work will be lost. It is best to take care of it for a period of time, so that the sperm is strengthened and the sperm is nurtured.
