In medicine, male infertility usually refers to a couple who have lived together for more than one year after marriage, have normal sex life, and have not taken any contraceptive measures, but the wife is unable to have children due to male reasons.

With the changes in people's lifestyles, the natural thing of "conceiving a child" seems to be becoming more and more difficult. Generally, women will make a lot of preparations before pregnancy, while men seem to just need to "put in the effort" according to the time. In fact, men should also prepare early for pregnancy.

First, keep your mouth shut and open your legs. You should start quitting smoking and limiting alcohol 3-6 months in advance to ensure sperm quality. Avoid cottonseed oil, because gossypol can destroy spermatogenic cells and cause infertility; eat more vegetables to supplement adequate vitamins; eat oysters and other seafood every week to supplement sufficient zinc and other trace elements; do aerobic exercise every week , but don’t ride for long periods of time.

Secondly, we must grasp the best childbearing age. Today’s young people are “hard to stand up in their thirties.” In big cities such as Beijing and Shanghai, young people are getting married later and later. It is difficult to have children before the age of 30. Patients in their 40s are everywhere. As everyone knows, age is the natural enemy of fertility. If you want to ensure sperm quality, try to complete childbirth before the age of 30, and no later than 35 years old.

Finally, do a semen test. Although the new marriage registration regulations have canceled premarital examinations, I still strongly recommend that men get corresponding examinations before pregnancy. Male semen analysis is a must-check item. It can directly reflect male fertility and determine whether treatment is needed and how long it will take.

Causes of decreased male fertility

1. Fast food

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

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. Laptop

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 use mobile phones.

6. Diapers

German scientists believe that diapers, which many young parents find convenient and worry-free, will cause baby boys to be infertile when they grow up. Diapers can increase the temperature of a baby boy's reproductive organs and damage them, leaving him with symptoms.

7. Pesticides

A 2001 study from Argentina 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. Tights 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.

9. 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.

10. Smoking

Men who smoke frequently are three times more likely to be infertile than men who have never smoked. Smoking causes the greatest damage to male reproductive health between the ages of 30 and 40. However, if men quit smoking two months later, their sperm quality will improve.

11. Don’t like to drink water

Not drinking enough 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. >>>Ten ways to improve sperm quality

12. Gluttony

Scientists in Atlanta, USA, have discovered that when men overeat, the quality of their sperm is 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 seafood contains too much mercury, a chemical harmful to reproduction, due to industrial pollution of the ocean. Therefore, eating too much seafood will increase the mercury content in the blood, eventually leading to male infertility.
