In 1991, Danish scientists first discovered that men's sperm counts had dropped by about half over the past 50 years. 14 years have passed, and Russian scientists are still working to find the cause of sperm decline. The latest article in the British "Independent" reported on the 13 male reproductive "killers" summarized by scientists.

1. Fast food

As the pace of modern life continues to accelerate, more and more men are eating fast food in order to save time and convenience. in the team.

Fast food contains many soy products. However, soybeans contain a hormone similar to estrogen. If the intake of this hormone is large, it will show some of the effects of human estrogen, thus inducing male reproductive problems.

2. Driving a car

The development of modern transportation has made the car a manifestation of male identity. Italian researchers found that taxi drivers, professional drivers, and truck drivers had the most significant decline in fertility. Driving for more than 2 hours straight is enough to damage a man's sperm quality. When driving, men should leave the car for 10 minutes after every hour of driving.

3. Traffic pollution

Pollutants such as nitrogen oxide and lead in the air are another killer of male reproductive problems. Scientists have found that men who work or live near highways for more than six hours a day have significantly worse sperm quality than other men of the same age.

4. Laptops

Long-term regular use of laptops can also damage male reproductive health, because the heat emitted by laptops during work can inhibit sperm production. . Therefore, when using a laptop, it is best not to place it on your lap.

5. Mobile phone

Hungarian scientists believe that the radiation emitted by mobile phones can kill or damage one-third of male sperm. Although there is no consensus on this conclusion, it is an undeniable fact that men who use mobile phones for a long time do have lower reproductive capacity than those who do not.

6. Diapers

German scientists believe that diapers that many young parents find convenient and worry-free will cause baby boys to grow up without Education. Diapers can increase the temperature of a baby boy's reproductive organs and damage them, leaving him with symptoms.

7. Pesticides

A study from Argentina in 2001 confirmed that long-term exposure to pesticides does have an impact on male fertility. Experts say that men’s reproductive organs are one of the most sensitive organs to harmful chemical substances in the surrounding environment. After pesticides are diffused in the air, their harmful substances first directly act on the reproductive organs, leading to imbalance of male hormone secretion and ultimately affecting the male reproductive organs. The entire reproductive system.

8. Smoking

Men who smoke frequently are three times more likely to be infertile than men who have never smoked. Smoking is harmful to those between 30 and 40 years old. Male reproductive harm is greatest. However, if men quit smoking two months later, their sperm quality will improve.

9. Tight pants and hot baths

Wearing tight underwear or tight leather pants can cause male reproductive problems. Bathing with water that is too hot can also damage male reproductive health.

10. Coffee

Coffee can also damage male sperm. The caffeine contained in coffee makes sperm inactive, so British scientists recommend that men drink coffee in moderation.

11. Not liking to drink water

Not liking to drink water can also lead to male reproductive problems. Although scientists have yet to fully understand how dehydration specifically affects male reproductive health, facts show that men who love drinking water have better reproductive performance.

12. Overeating

Scientists in Atlanta, USA, found that when men overeat, the quality of their sperm will be damaged. Because excessive intake of fat and other nutrients from a large amount of food increases the temperature of the sperm and damages it.

13. Like to eat seafood

Scientists in Hong Kong, China have discovered that because the ocean is polluted by industry, seafood contains too many chemicals that are harmful to reproduction. Substance mercury. Therefore, eating too much seafood will increase the mercury content in the blood, eventually leading to male infertility.
