What is the effect of smoking on sperm?

If many people want to prepare for pregnancy, they will adjust their physical condition in advance. Both men and women will improve some bad habits and increase exercise. For men, if they are preparing for pregnancy, they must stop smoking. Many people know, but do not understand the impact of smoking on sperm. Today we will give you a brief introduction to the harm of smoking to sperm.

1. Smoking causes sperm mutation

Smoking is a mutagenic substance that causes sperm to develop and can affect the maturation and proliferation of germ cells. Heavy smokers have a significantly higher rate of chromosomal abnormalities and a higher rate of sister chromatid exchanges in peripheral blood lymphocytes than non-smokers.

2. Smoking causes sperm bacteria to mutate

Cigarette smoke condensate can induce bacterial mutations and is a potent mutagen for sister chromatid exchange in human lymphocytes in culture medium. Population data show that the incidence of chromosomal damage in peripheral blood lymphocytes of smokers is related to the type of cigarettes smoked. Hopkin et al. found that lymphocyte damage is severe in heavy smokers and those who smoke unfiltered cigarettes.

3. Smoking affects sperm motility

Smoking can inhibit the enzyme system of sperm through cigarette smoke condensate, which has a certain impact on the vitality of sperm. This is due to the inhibition of bile acetylase.

Now we know that smoking does have a certain impact on male sperm, sometimes it will cause male sperm mutation, and it will also greatly affect the vitality of sperm, making it more difficult for women to conceive. Especially if you smoke more often, the rate of chromosome abnormalities will be higher, so even if a woman successfully becomes pregnant, the fetus is likely to develop abnormally.
