What are the factors that affect sperm quality? 7 major factors affecting sexual quality

Sperm is a necessity for human reproduction, but research has found that in addition to genetics and genetics, the quality of Chinese male sperm has been deteriorating over the past 50 years

Sperm is a necessity for human reproduction, but some studies have found that in the past 50 years, the quality of sperm in Chinese men has become increasingly poor. In addition to genetic and some organic diseases, male infertility is closely related to lifestyle habits. So, what are the factors that affect sperm quality in daily life?

1. Sexual life has become chaotic

Disordered and unclean sexual life can easily cause male reproductive tract infections. Genital tract infections are caused by pathogens such as gonococci, tuberculosis bacilli, viruses, mycoplasma, chlamydia, and trichomonas, among which mycoplasma and chlamydia infections are the most common. Genital tract infections first affect the production and transportation of sperm, leading to a decrease in sperm count and a decrease in reproductive ability. Genital tract infections also lead to changes in sperm motility. Genital tract infections can inhibit the secretion of accessory gonads, leading to insufficient semen secretion, insufficient semen nutrition, changes in pH value, and semen composition, affecting the sperm growth environment, seriously reducing sperm vitality and quantity, and leading to infertility

2. Smoking and Alcohol Addiction

Men are very sensitive to toxins in tobacco and wine, especially reproductive cells. Research has shown that nicotine in tobacco can reduce the secretion of sex hormones and kill sperm. The sperm survival rate of smokers who smoke 30 cigarettes per day is only 49%, while the secretion of androgens in smokers is 16% to 47% lower in non-smokers, which correspondingly reduces the ability to produce sperm. Long term alcohol consumption can damage the spermatogenic cells of the testes and affect sperm production.

3. Long term warm environment

For example, long-term high-temperature operations, hot baths, and wearing tight fitting clothing can hinder the function of the scrotum to regulate temperature. Many men wear tight fitting clothes for a long time to show off their healthy figure. As is well known, tight fitting clothing can firmly adhere the scrotum and testicles together, preventing the heat dissipation function of the scrotal skin, thereby increasing the local temperature of the testicles and hindering sperm production. In addition, wearing tight clothing can also restrict and hinder blood circulation to the scrotum, forming testicular congestion and leading to infertility. The testicles are organs that produce sperm. The temperature of the testicles during spermatogenesis must be between 35.5 ℃ and 36.5 ℃, which is 1-1.5 ℃ lower than normal body temperature. Frequent use of hot water for bathing, especially in bathtubs and saunas, can keep the scrotum in a high temperature state and affect the spermatogenic function of the testicles.
