Everyone knows that sperm quality represents male fertility, but do you know what daily bad habits can kill sperm? Let’s take a look below.

The common sperm killers in life include the following:

1. Wear tight jeans. Tight jeans not only compress the male reproductive organs and affect the normal development of testicles, but are also not conducive to the survival of sperm because they are not breathable and do not dissipate heat.

2. Jiuqi racing. The height of the racing handlebar is lower than the seat, the center of gravity tilts forward, and the curvature of the waist increases. The testicles and prostate of the perineum are close to the seat cushion. After being squeezed for a long time, it will cause ischemia, edema, and inflammation, which will affect the production of sperm and Normal secretion of prostatic fluid and semen causes infertility. Therefore, young men should not ride a racing car for a long time, and should use a sponge cover to protect the perineal cushion.

3. The bathing temperature is too high. Under normal circumstances, sperm must be in a constant temperature environment of 34°C to 35°C for normal development. When taking a bath, the water temperature is too high, which often hides "murder". For example, the room temperature in a sauna can be as high as 70°C to 80°C, which is more than twice as high as a normal bathroom temperature, which is not conducive to the growth of sperm, or may cause too much "dead sperm" and cause infertility. Therefore, young people should be careful about sauna bathing, and the water temperature for daily bathing should be around 34°C.

4. Diet deficient in zinc and selenium. The trace element zinc can promote sperm motility, prevent premature disintegration of sperm, and facilitate the combination with eggs. It can be seen that zinc has a significant impact on fertility. Selenium is also an essential trace element for the human body, almost entirely from food. Therefore, young men should not be picky about their diet and should pay attention to eating more foods rich in zinc and selenium, such as fish, oysters, liver, soybeans, brown rice, etc.

5. Inhalation of kitchen fumes. A study by Shanghai Tietou University School of Medicine found that there are 74 chemicals in kitchen fumes that can cause cell mutations and lead to infertility, becoming a new "evidence" of "family killers". They found that fruit flies that were fed condensed oil from a kitchen hood oil cup had a mutation rate of 0.54% in the chromosomes of their cells, and 2.8% of the flies were infertile, indicating significant damage to their reproductive systems.

6. Long-term consumption of certain foods containing nitrite food preservatives or meta-sulfonamide food colorants, raw cottonseed oil, etc. can also lead to a decrease in sperm quantity and quality.

7. Celery is also a sperm killer. Men who eat more celery will inhibit the production of testosterone, which will have a spermicidal effect and reduce the number of sperm. According to reports, some foreign doctors have found through experiments that after healthy, fertile young men eat celery for many days in a row, their sperm count will be significantly reduced to the point where it is difficult to conceive. This situation will recover a few months after stopping eating celery. normal.

8. Medical drugs stimulate sperm: Sedatives, sleeping pills, anti-cancer drugs, hormone drugs, etc. in drugs hinder the growth of sperm. Therefore, men should try to avoid long-term and large-scale exposure to such harmful substances.
