In recent years, outpatient clinics have shown that the incidence rate of male infertility has significantly increased. These phenomena are not only related to living habits, but also related to some work environments, such as high radiation and high heat environments. Compared to men in rural areas, men in cities face more severe environmental pollution impacts. In rural areas, there are also a small number of men who take cottonseed oil intermittently or continuously when they are young. There is gossypol in cottonseed, which is harmful to men's sperm production system. At present, many research departments are using gossypol to study male contraceptives. This situation is also directly related to the weak promotion of reproductive knowledge at the grassroots level.
In addition, current environmental changes are also very unfavorable for fertility. There are reports in the UK that pollution in the living environment will have a more serious impact on human reproductive health than genetic variation. Director Cui Yanguo highly agrees with this viewpoint. The male reproductive system is the most sensitive and fragile, and it is very susceptible to external influences and interference.
Among male infertility, only a very few are congenital, while acquired factors account for the vast majority, with semen quality issues accounting for the vast majority. The reasons for the decline in sperm quality are some congenital or acquired diseases, while others are caused by adverse factors in daily life.
There are several factors that have been proven in research to have an impact on sperm quality, and men should especially avoid:
1. Formaldehyde and other chemicals can reduce sperm count, reduce motility, and cause deformities. Domestic and foreign experiments have long proven that chemicals such as formaldehyde (mainly caused by decoration pollution in cities), xylene, and organophosphorus pesticides can damage the protective barrier of the testes and invade sperm cells, leading to a decrease in sperm count, decreased motility, and malformations.
2. Research has confirmed that 44 ℃ is the critical point that affects sperm survival. If a man bathes in hot water above 44 ℃ for half an hour, sperm motility will be significantly reduced and fertility will be temporarily lost.
3. The epididymis is very sensitive to radiation exposure. The sperm stored in the epididymis can become deformed when exposed to X-rays.
4. Estrogen affects sperm growth, such as health products such as royal jelly.
5. Excessive drinking impairs sperm function.
6. Drugs.
7. Prostatitis.
