Men who smoke everywhere. As we all know, smoking and drinking are not conducive to giving birth to excellent babies. Especially during pregnancy, if men don't leave their hands when smoking, sperm will be deformed, so the baby born will naturally be worse. So does it matter if dad smokes and gets pregnant? When will men quit smoking?
Smoking can lead to abnormal sperm.
Psychologists at the University of Florida in the United States have concluded through controlled experiments that smoking will weaken male reproductive function. They compared 43 smokers and 43 non-smokers in the two groups. All sperm are too large, too small, concentrated or deformed, accompanied by morphological abnormalities such as vacuoles, multiple heads, multiple tails and tail deformities. The results showed that the normal sperm value of smokers was lower than that of non-smokers. At the same time, it is found that the rate of sperm abnormality is related to the number of smokers. Smoke concentrate contains carcinogens and also exists in smokers' body fluids. Sperm receiving this carcinogen is prone to genetic damage.
Smoking produces carbon monoxide, which prevents red blood cells from combining with oxygen. Nicotine can constrict blood vessels, reduce the blood flow of placental blood circulation, make placenta and fetus anoxic, lead to premature birth, and even cause lifelong regret of fetal malformation. Smoking will reduce the normal sperm count and sperm motility. For example, an adult male smokes 30 cigarettes a day, and the sperm survival rate is only 40%, which is undoubtedly not conducive to fertility.
Smoking can cause chromosomal abnormalities.
In order to clarify the harm of tobacco to health from the chromosome level, Dr. Karenno of the United States observed the chromosomes of different smokers. The results showed that only 7- 10 of 46 chromosomes in normal people were abnormal, and about 20 chromosomes in smokers could have sister haploid exchange. At the same time, it is also found that the longer the smoking history, the greater the smoking volume and the higher the chromosome abnormality rate. Even after giving up smoking for 3 months, the influence of smoking still exists. In addition, the proportion of cells with abnormal chromosomes in smokers is 70%, while that in non-smokers is only about 15%.
If you smoke regularly during pregnancy, it may lead to infertility and low sperm quality. So you should try to quit smoking and drinking, which is also very good for the health of the fetus. However, it is also a rare phenomenon that smoking leads to abnormal fetal development. During pregnancy, the father often smokes, which will have a certain impact on the child's health, but relatively speaking, the impact is not great, but there is a certain probability, so the father should pay more attention to reasonable health care. For the sake of fetal health, it is best to quit smoking and drinking, so as not to affect the fetal health.
