Which factors will lead to the decline of sperm quality in men

Male infertility is a headache disease for male patients, which affects the patient's lineage, and some men often fall into extreme inferiority because of this problem. For those men who are still in the pregnancy stage, good sperm quality directly affects the next generation, so what are the factors that lead to the decline of sperm quality?

Five factors leading to the decline of sperm quality

1. Excessive or improper sexual life

Although the testicle can produce tens of millions to hundreds of millions of sperm per day, it takes five to seven days for the sperm to mature and reach a sufficient number after a single ejaculation. If the number of sexual life is excessive or uncontrolled, the amount of sperm ejaculated each time is small, so it is not easy to conceive. In addition, the interruption of sexual life, masturbation or long duration of each sexual life will lead to aseptic prostatitis, which will directly affect the nutritional composition of semen and sperm vitality, causing infertility.

2. Too much contact with female substances

With the development of society and the changes of various environments, people have more and more opportunities to contact with low-dose female substances for a long time, such as the artificial fresh water fish, poultry, etc. eating such foods for a long time is also an important reason for the decline of the number of male sperm.

3. Disordered and unclean sexual life

Sexual confusion and uncleanness are easy to cause male reproductive tract infection. Gonococcus, Mycobacterium tuberculosis, virus, mycoplasma, chlamydia, trichomonad and so on are the causes of reproductive tract infection, of which mycoplasma and Chlamydia are the most common. Reproductive tract infection first affects sperm production and sperm transport, resulting in oligospermia and decreased reproductive capacity. Reproductive tract infection can also cause changes in sperm motility. Reproductive tract infection can inhibit the secretion of accessory gonads, cause insufficient semen secretion, lack of semen nutrition, change of pH value, and change of semen composition, thus affecting the growth environment of sperm, resulting in serious decline in sperm motility and quantity, resulting in infertility.

4. Smoking and drinking

Men are sensitive to toxins in tobacco and alcohol, especially reproductive cells. According to the research, nicotine in tobacco can reduce the secretion of sex hormone and kill sperm. The sperm survival rate is only 49% for those who smoke 30 cigarettes a day, and the secretion of androgen in smokers is 16% to 47% less than that in non-smokers, so that the sperm production ability is correspondingly reduced. Long term drinking will damage spermatogenic cells of testis and affect sperm production.

5. Testicles damaged by warm environment

Such as long-term high-temperature operation, hot bath, long-term wear leggings, will make the scrotum temperature adjustment function produce obstacles. Many men wear leggings for a long time in order to show their body-building body. However, leggings will stick the scrotum and testicles firmly together, so that the heat dissipation function of the scrotum skin can not be exerted, thus increasing the local temperature of testicles and hindering sperm production.

In addition, wearing tight pants will restrict and hinder the blood circulation of scrotum, form testicular blood stasis, and lead to infertility. Testis is the organ that produces sperm. The temperature of testis must be between 35.5 ℃ and 36.5 ℃, which is 1-1.5 ℃ lower than the normal temperature. Often take a bath with very hot water, especially a bath or sauna, so that the scrotum is often in a high temperature state, which will affect the spermatogenic function of the testicle.
