Does male smoking affect fertility?

Smoking is something that many men do. This habit is particularly bad. It not only causes serious harm to one's own body, but also endangers the health of others. In particular, smoking by men will have a serious impact on fertility, mainly because smoking will affect the quality of sperm. Therefore, men who smoke must pay attention to it. So, does smoking affect fertility? In response to such a question, we will understand it through the following introduction.

1. Heavy smoking can damage fertility. Women who smoke more than 10 cigarettes a day have an infertility rate of 10.7% after stopping contraception, while the infertility rate of non-smokers is only 5.4%. The fertility of women who have quit smoking is roughly the same as that of women who have never smoked.

2. The normal value of sperm in smokers is lower than that in non-smokers. At the same time, it is also found that the sperm deformity rate is related to the amount of smoking. The concentrated smoke contains carcinogens, which are also present in the body fluids of smokers. When sperm is exposed to these carcinogens, genetic damage is likely to occur.

3. In a normal person, only 7 to 10 chromosomes are abnormal among the 46 chromosomes, but in smokers, up to 20 chromosomes may have sister haplotype exchanges. At the same time, it was found that the longer the smoking history and the greater the amount of smoking, the higher the rate of chromosome abnormality; the effects of smoking still exist even after stopping smoking for 3 months. In addition, the proportion of cells with chromosome abnormalities is 70% in smokers, while it is only about 15% in non-smokers.

Through the above introduction, we know that male smoking will affect fertility, so men who want to have children are best to quit smoking, at least three months after quitting smoking before getting pregnant. This is the best way to ensure eugenics. In addition, you should also pay attention to physical exercise. Before pregnancy, you also need to pay attention to your daily diet and eat more fresh vegetables and fruits.
