It is worth noting that the decrease in sperm quality has shown a trend towards younger age. In recent years, there have been frequent reports from multiple sperm banks across the country that the quality of college students' sperm, once considered a "sperm rich mine," is worrying. Not only is the quantity not up to standard, but the vitality is also declining. A family planning research institute once publicly collected sperm in universities, but unexpectedly, less than 50 of the 400 college student volunteers who came to donate sperm were qualified.
An unhealthy lifestyle is the culprit. Due to the high work pressure, frequent sedentary behavior, irregular diet, and insufficient sleep in men, these are the main reasons for the decline in sperm quality. Nowadays, young people generally enjoy nightlife. At two or three o'clock in the morning, bars of all sizes were still bustling and bustling, with each one getting drunk amidst the smoke; Some people just walked out of the bar and shouted to go take a sauna. Little did they know that it was these so-called fashion lifestyles that greatly reduced the fertility of men in their prime.
Sperm is very "delicate" and can easily "get angry". When exposed to radiation, high temperatures, staying up late, drinking alcohol, smoking, sitting for a long time, etc., it will deform, mutate, and even "die". Tobacco and alcohol are both natural enemies of sperm. Foreign studies have long shown that men who smoke more than 30 cigarettes a day experience more than four times more abnormal changes in sperm morphology compared to non-smokers. Drinking alcohol, like smoking, has a killing effect on sperm, which can cause poor sperm development and reduce its vitality.
When men sit in the sauna sweating profusely to "enjoy", they are also exhausting their "energy". Because sperm in the testicles must develop normally in an environment around 35 ℃. The study found that normal men immersed in 43 ℃ hot water for 20 minutes not only reduced sperm motility, but also prevented sperm production.
In fact, what strikes a man's pride is often what appears to make him proud. Laptops, cars, etc. are often used by men as symbols of status and success. But research has confirmed that driving continuously for more than 2 hours is enough to cause a decrease in male sperm count. Putting a laptop on your lap for operation, the heat dissipation of the computer will directly increase the temperature of the testicles, inhibit sperm production, and affect their vitality.
In outpatient clinics, we found that taxi drivers, professional drivers, and truck drivers have significantly higher rates of infertility caused by abnormal semen compared to men from other professions. "Experts pointed out that sperm are most afraid of prolonged sitting and high temperatures. They sit for seven or eight hours without moving their buttocks. In the summer, the sun shines again, and the car mats get hot. This temperature is a "fatal test" for sperm. If the driver is still wearing tight underwear, the blood circulation in the scrotum is restricted, coupled with poor air flow and high local temperature, it also brings resistance to sperm production.
