Half a Century of "Blood and Tear History" of Human Sperm
Good seeds are essential for the healthy growth of crops, and healthy sperm is essential for children's growth. However, over the past half century, there has been an extreme decline in the sperm that humans rely on to transmit, shining a red light on humanity. And this landslide was caused by humans themselves, which is equivalent to the suicide of an extinct species.
In the past 50 years, male sperm has almost halved and is still decreasing at a rate of 2.1% annually. According to statistics, in the 1940s, men had an average of 130 million sperm per milliliter of semen, which has since decreased to 66 million. In 1960, 5% of men had less than 20 million sperm per milliliter of semen. In the 1970s and 1980s, the number of males with less than 20 million sperm gradually increased. In the 1990s, the world's environmental pollution became increasingly severe, with this rate skyrocketing from 5% in the 1960s to 15%. To successfully fertilize an egg, 20 million sperm is far from enough.
At the same time, the quality of human sperm is quietly declining. The proportion of deformed and inferior sperm is increasing, and its vitality, penetration, and fertility rate are decreasing, resulting in an increasing proportion of male infertility year by year. According to some statistics, only 8% of men came to seek advice due to infertility in 1960, but now it has reached over 40%. In the 1970s, the proportion of male to female infertility patients was 3:7, and in the 1990s, this proportion had risen to 1:1.
For this reason, authoritative figures have issued a warning: if effective measures are not taken in a timely manner and continue like this, in less than a century, the sperm that humans rely on for inheritance will seriously decline, and it will be difficult for humans to reproduce offspring!
Don't let your sperm become a rare liquid
The decreasing number of sperm directly threatens the quality of human fertility. This has caused concern and unease among experts from around the world. What is the reason for such a bad trend? After years of clinical observation and research, scientists have found that the deterioration of the external environment such as chemical pollution, radiation, electromagnetic waves, and noise is like a fierce killer of human sperm. Various physical, chemical, and biological harmful factors not only cause disease and cancer, but also quietly endanger the continuation of human race.
There are significant occupational characteristics among people with infertility. According to Professor Cheng Huaijin, an expert in the urology of Shanghai International Peace Maternal and Child Health Hospital, engaging in radioactive work, high-temperature work, and exposure to pesticides, paints, coatings and other toxic substances, such as lead, mercury, phosphorus, etc., long exposure time and no protective measures can make harmful substances directly affect the reproductive system. Drivers, carpenters, electricians, plumbers, builders, and others are all high-risk groups for infertility. People engaged in these professions are prone to infertility due to their exposure to high temperatures and lack of necessary labor protection measures.
For example, drivers often set out early and return late, have irregular rest and diet, and are highly stressed at work, all of which can affect the quantity, quality, and survival rate of sperm; Electricians may experience mild electric shock, while plumbers and welders often come into contact with electrical welding, which can have a certain killing effect on sperm. In addition, in modern society, the pace of work and life is accelerating, and some people are under high work pressure, mental stress, and often in a state of physical fatigue. Some people also have irregular work and life, excessive socializing, and frequent alcohol abuse, which can affect the secretion of male hormones, leading to a decrease in sperm quality and quantity.
Sperm is particularly sensitive to high-temperature environments. According to experts, under normal physiological conditions and general environment, the temperature of the scrotum is more than 3 ℃ lower than the body temperature, and the temperature of the testis and epididymis in the scrotum is also significantly lower than the body temperature, which is one of the important conditions to ensure spermatogenesis and maturation. All factors that increase the temperature of the scrotum, testis and epididymis will likely create obstacles to the occurrence and maturation of sperm. Research has found that soaking in hot water 3-4 times a week at temperatures above 40 ℃ significantly increases the number of sperm with head deformities and immature sperm. If one works in a high-temperature environment for a long time, often takes a sauna, or wears tight jeans, it can increase the temperature of the scrotum, testes, and epididymis, which affects the generation and maturation of sperm.
In addition, drug abuse, malnutrition, sexually transmitted diseases, and addiction to drugs and smoking are all considered invisible killers of sperm.
