What are the harmful effects of smoking on semen?

What are the harmful effects of smoking on semen? My husband and I have been married for more than a year. At that time, we wanted to have fun for another year and did not have a baby right away. After discussing with my parents-in-law, they agreed. Now the one-year agreement is up. My mother-in-law often reminds us that it is time to have a baby. We really plan to have a baby while our parents are still young and can help us take care of the child. But my husband keeps smoking. I asked him to stop smoking during the period of trying to have a baby and wait until we have a baby. Now he refuses to believe that smoking has an impact on sperm. What are the harms? Let me tell you.

The main ingredient in tobacco is nicotine. Scientists have confirmed that nicotine can have an anti-fertility effect and cause infertility. Nicotine can directly affect sperm production. Smoking can also cause penile artery contraction, testicular and epididymal hemodynamic changes, which can affect spermatogenic cell development and hinder sperm production and maturation. After quitting smoking or reducing smoking for half a year, changes can be seen, with sperm count and motility both showing an upward trend. The more cigarettes you smoke every day or the longer your smoking history, the higher the sperm deformity rate, the fewer normal sperm, and the lower the motility. Moreover, if your wife is pregnant, your husband's smoking can lead to an increase in fetal mortality.

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.

The above content is a simple summary of the harmful effects of smoking on semen that I found on the Internet. Smoking is not a good thing. You should still quit smoking in normal times. Now that you want a baby, you should quit smoking even more. Smoking has an impact on the health of the child. If you want to have a healthy baby, don't smoke.
