Men's semen quality decreases by 1% per year
The Institute of Science and Technology of the National Planning and Family Planning Commission from 1981 to 1996 comes from the sperm analysis data of 11,726 people with a total of 11,726 sperm analysis data from 39 cities and counties, including Beijing, Shanghai, Tianjin, etc.Men's semen quality is decreased at a rate of 1%per year, and the number of sperm decreases by more than 40%.The data statistics from the Shanghai Human Sperm Library also show that in 2004, the pass rate of Shanghai volunteer sperm donors did not exceed 21%.
In clinical clinics, Professor Cheng found that the proportion of men's infertility is increasing, and one of the reasons for infertility is the decline in sperm quality.Many men who see a doctor disagree with the problem of drinking and smoking. They think that it is enough to properly control before preparing for birth, and ignore the impact of this unhealthy lifestyle on the body.
Drunk once three months to recover
Professor Cheng told reporters that alcohol directly affects the knowledge of human liver and male testicles.Studies have found that patients with chronic alcohol poisoning will cause testicular atrophy, leading to a decline in semen quality.Therefore, the damage that the sperm that is drunk once can not be recovered in one or two days. If you want to return to the sperm quality before drinking, it will take at least three months.Experts believe that a man with a maternity plan can only be conceived for at least three months after being drunk to ensure the health of the fetus.Just ask the Health Network
Smoking too much can cause sperm malformations
Similarly, the number of normal sperm sperm for long -term smokers has also decreased, with an average decrease of about 10%.For those who smoke 21-30 a day, the incidence of deformity sperm has increased significantly; those who suck more than 30 branches, the incidence of deformity sperm is higher.The longer the smoking time, the more deformed sperm, and as the number of normal sperm continues to decrease, sperm activity will also weaken.Just ask the Health Network
Some people have analyzed more than 5,000 pregnant women and found that their husband smoke more than 10 people every day, and the prenatal mortality rate of fetal delivery is greatly increased; the more smoking, the higher the mortality rate.Women who smoke their husbands are about 2.5 times higher than her husband's non -smoking.
