The dangers of smoking are believed to be understood by everyone, so men try to smoke as little as possible for the health of the next generation. Let’s take a look at how much harm smoking has on future generations!

Does smoking affect the next generation?

The harm of smoking to future generations:

1, smoking can cause abnormal sperm

Psychologists at the University of Florida in the United States have concluded through controlled trials that smoking weakens men’s reproductive function. They compared the 43 people who smoked and did not smoke into two groups. The sperm was too large, too small, concentrated or with vacuolar deformation, long, multi-tail and tail deformity as morphological abnormalities. It was found that the normal value of sperm in smokers was lower than that in non-smokers. At the same time, it was also found that the rate of sperm deformity was related to the amount of smoking. The concentrate of the smoke contains carcinogens, which are also present in the body fluids of the smoker. The sperm receives the carcinogen and is susceptible to genetic damage.

2, women smoking during pregnancy can produce a variety of harm

The harm of smoking is great, especially the impact on the fetus: (1) The incidence of premature babies is high. According to a survey of 7499 pregnant women , the prevalence of preterm infants was 12.5% ​​in the smoking group and 6.8% in the non-smoking group. The difference was nearly doubled. (2) Smoking causes uterine contractions, increasing the incidence of miscarriage. (3) The incidence of congenital malformations is high. According to a group report, the incidence of congenital heart disease in infants was 0.77% in the smoking group and 0.47% in the non-smoking group, with significant differences. The effect on the placenta: smokers due to hypoxemia, clinical early detection of placental stripping, placental infarction and placenta prevalence increased. Therefore, if the couple is pregnant, at least three months or more to quit smoking, to ensure that the harmful substances in the body are excreted. Moreover, it is necessary for the expectant mother to pay attention to: to avoid the inhalation of smoke, to stay away from smoking, and to avoid “second-hand smoke” at home.

3. Smoking affects fertility

The most important finding of the Oxford Family Planning Association in fertility research is that fertility continues to decline significantly with increasing smoking. After 11 and a half years of research on 17,000 women of childbearing age, the study concluded that a large number of cigarettes can damage fertility, and women who smoke more than 10 cigarettes a day are infertile after stopping contraception. The rate was 10.7%, and the rate of infertility in non-smokers was only 5.4%. The fertility of women who have quit smoking and those who never smoke are about the same.

4, smoking can cause chromosomal abnormalities

In order to clarify the health hazards of tobacco at the chromosomal level, Dr. Carenno of the United States conducted chromosome observations on different smoking groups and found that there are generally only 7-10 abnormalities in 46 chromosomes of normal people, while smokers can Sister monomer exchange occurs up to 20 chromosomes. At the same time, it was found that the longer the smoking history, the greater the amount of smoking, and the higher the chromosomal abnormality rate; the effect of smoking still exists even after stopping smoking for 3 months. In addition, the proportion of cells with chromosomal abnormalities is 70% for smokers and only about 15% for non-smokers.

Through the above experts to briefly introduce the harm of smoking to future generations, I believe that everyone is aware of the dangers of smoking. In order to avoid smoking affecting future generations, men should quit smoking in time. I hope the above can help everyone. If you have any questions, please continue to visit the Health Online!
