Forty percent of the infertility problem lies with the husband.
In the 1970s, the standard of sperm qualification was 65.438+0.5 billion sperm per milliliter, and now 20 million sperm per milliliter are "up to standard".
Tadpoles in men are not only a barometer of male reproductive health, but also an indispensable "seed" for the next generation.
"Twenty million is the bottom line. It's hard to imagine anything lower than this. " Li Jun, director of urology department of Wuhan Hospital of Traditional Chinese Medicine, told reporters that in the 1970s, the number of sperm per milliliter of semen for men was 65.438+0.5 billion, which was qualified. Now, the number of sperm contained in each milliliter of semen is 20 million, which means "passing the test".
The Institute of Science and Technology of China National Population and Family Planning Commission has studied the sperm analysis data of 39 cities and counties 1 1726 people from 198 1 996, and found that the semen quality of Chinese men is declining at the rate of 1% every year, and the number of sperm is reduced by 40%. The higher the level of modernization, the faster the sperm quality declines.
In addition to the decrease of sperm quantity, sperm quality also showed a downward trend. Shen Guoqiu told us that whether tadpoles are really healthy and strong depends on three items: sperm number, sperm morphology and athletic ability (agile and regular swimming ability). Nowadays, few men can get a "grand slam" in these three events, and it is even difficult to "get full marks" in a single event. As long as 60% of the sperm in all projects are normal, it is quite good.
At the same time, it should be noted that the decline of sperm quality has shown a trend of younger age. In recent years, many sperm banks in China have frequently reported that the sperm quality of college students who were once regarded as "sperm-rich mines" is worrying, not only the quantity is not up to standard, but also their vitality is declining. A family planning institution once openly recruited sperm in colleges and universities, but surprisingly, less than 50 of the 400 college students who came to donate sperm were qualified.
"Black hand of killing sperm" is everywhere.
"An unhealthy lifestyle is the culprit. Due to the high work pressure of men, there are often many situations such as sitting more and exercising less, irregular diet and lack of sleep, which are the main reasons for the decline of male sperm quality. " Li Jun pointed out that young people nowadays generally like nightlife. At two or three o'clock in the morning, bars of all sizes are still very lively, and they are all drunk in the smoke; Some people just walked out of the bar and shouted for a sauna. As everyone knows, it is these so-called fashionable lives that greatly reduce the fertility of mature men.
According to Li Jun, sperm is very "fragile" and easy to "lose temper". Exposure to radiation, high temperature, staying up late, drinking, smoking, sedentary, etc. It will deform, mutate and even "die". Alcohol and tobacco are natural enemies of sperm. A long time ago, foreign studies showed that the abnormal sperm morphology of men who smoked more than 30 cigarettes a day was more than four times higher than that of non-smokers. Drinking alcohol, like smoking, will kill sperm, make sperm stunted and reduce sperm vitality.
When men are sweating and sitting in the sauna to "enjoy", they are also overdrawing their "energy", because the sperm in the testis can only develop normally at around 35℃. The results show that soaking normal men in hot water at 43℃ for 20 minutes will not only reduce sperm motility, but also prevent sperm production.
"In fact, what hurts men's self-esteem is often what makes men proud on the surface." Shen Guoqiu said, laptops, cars and so on. Usually regarded by men as a symbol of status and success. However, studies have confirmed that driving continuously for more than 2 hours is enough to reduce the sperm count of men. When you put your laptop on your knee, the heat dissipation of the computer will directly increase the temperature of your testicles, inhibit the production of sperm and affect its vitality.
