What are the harms of nicotine to sperm?

In daily life, we can see people smoking everywhere. It is true that there are too many men who have the habit of smoking. Many people have a long history of smoking. As we all know, cigarettes contain nicotine, which is very harmful to the human body. People who smoke frequently are easily harmed by nicotine. For example, nicotine can cause damage to men's sperm.

Nicotine's harm to sperm:

Nicotine, commonly known as nicotine, is a bioalkaloid found in Solanaceae plants (Solanum), and is also an important component of tobacco. Nicotine can make people addicted or dependent (one of the most difficult addictions to quit), and people usually find it difficult to control themselves. Repeated use of nicotine also increases heart rate and blood pressure and reduces appetite. Large doses of nicotine can cause vomiting and nausea, and in severe cases, people can die. Nicotine is usually found in tobacco, which is an important reason why many smokers cannot quit smoking.

Nicotine is a foul-smelling, bitter, colorless, transparent oily liquid with high volatility. It is easily oxidized to dark gray in the air and can be quickly dissolved in water and alcohol. It is easily absorbed by the body through the oral, nasal and bronchial mucosa. Nicotine that sticks to the surface of the skin can also be absorbed and penetrated into the body. When nicotine enters the human body, it will produce many effects: such as nicotine in the extremities

Vascular constriction, increased heart rate, increased blood pressure, faster breathing, changes in mental state (such as becoming emotionally stable or excited), and promotion of platelet aggregation are the main culprits of cardiovascular diseases such as heart vessel obstruction, high blood pressure, and stroke.

Women who use oral contraceptives and smoke increase the risk of heart disease and blood clots in the veins of the lower limbs. When a pregnant woman smokes, the fetus in her body is also "smoking". The pregnant woman's smoking brings carbon monoxide and nicotine into the fetal blood flow, thereby reducing the supply of oxygen to the fetus and speeding up the fetal heart rate. The fetuses of pregnant women who smoke are more likely to be born prematurely and have low weight; they are more likely to get sick during infancy.

What are the effects of nicotine on sperm?

Studies have shown that nicotine in tobacco can reduce the secretion of sex hormones and kill sperm. For those who smoke 30 cigarettes a day, the sperm survival rate is only 49%. The secretion of male hormones in smokers is 16% to 47% less than that of non-smokers, which reduces the ability to produce sperm. Staying up late for a long time and excessive fatigue can also damage the spermatogenic cells of the testicles and affect sperm production. If you get rid of these bad habits, eat more foods that can strengthen sperm and remove toxins, help excrete toxins in the body, and provide sperm with a clean environment for development.

According to the research data of the National Family Planning Commission, from 1981 to 1996, the semen quality of Chinese men was declining at a rate of 1% per year, and the sperm motility rate and the normal sperm ratio decreased by 10.4% and 8.4% respectively. In the past decade or so, society has developed rapidly, people's work and life pace has accelerated, and the work pressure and intensity have continued to increase, making the living habits of many male friends worse. Therefore, quitting smoking, limiting alcohol, and reducing fatigue play a very important role in sperm quality.
