For many men, weak sperm is like a terrible bewitchment that may even prevent men from successfully becoming a father. How exactly does weak spermatozoa arise? Weak spermatozoa is a condition in which semen parameters have less than 50% of forward moving sperm (class a and b) or less than 25% of class a moving sperm, weak spermatozoa is also known as low sperm motility. (Grade a indicates good sperm motility and grade b indicates average sperm motility). Infections of the male reproductive system are a major cause of weak spermatozoa, such as epididymitis and prostatitis. Semen examination reveals increased white blood cells, poor semen liquefaction and decreased sperm motility. Another common cause of weak spermatozoa is varicocele, which not only affects the function of sperm production, but also causes the negative consequences of decreased sperm viability. The effect on sperm viability may be that anti-sperm antibodies bind to the tails of spermatozoa, which are hampered in viability, reduced motility, and poor penetration ability. Autosomal and sex chromosome aberrations affect sperm viability and forward motility, in addition to sperm count. For example, hypogonadal hypogonadism, hyperprolactinemia, and hyperestradiolemia can reduce spermatogenesis and decrease viability, thus reducing sperm quantity and quality. Lack of vitamins, lack of zinc, copper and other trace elements, smoking, drinking alcohol, engaging in high temperature, radiation occupations and exposure to chemical toxins can all cause a decrease in sperm vitality. 1, avoid excessive noise. According to the data, it is proved that men live in an environment of 70 to 80 decibels of noise for a long time, sexual function tends to weaken. 2, try not to use or less use of various chemical agents. Do not eat too much greasy food, quit smoking and alcohol. 3, avoid long masturbation. Masturbation triggers prostate congestion, leading to sterile prostatitis. In the daily diet, more food rich in calcium, zinc, arginine, will help to improve male fertility. Such as dairy, beans, seafood, etc.
