For a long time, cigarettes have been touted as a symbol of masculine male vitality.However, it turns out that smoking is one of the main culprits of men. What is the mechanism of smoking that causes impotence?
Cigarettes contain a variety of toxins. These toxins can cause penile arteries, thinner lumen, and blood flow to decrease significantly, and some even occur completely.Even though the stimulus is sufficient, but because there is no sufficient blood into the blood sinus, the penis sponge body is difficult to increase the volume and the texture is hardened, so it causes an erection difficulty or not strong, so that impotence is formed.
On the other hand, toxins in tobacco have inhibit the synthesis of testicular intercostatic hormones.Testicles are the main organs of men, and quality cells can synthesize androgen.The role of therogen is to promote the development of attached organs such as penis, epididymia, and vasters, and maintain their mature state.The decrease in the synthesis of androgen and the decrease in the content of the blood can affect the second sexual characteristics of men, such as the decrease in the beard, the sound of the sound, and also affect the normal sexual desire.
Smoke also contains some substances that can shrink blood vessels, such as slow -linter peptides.Through smoking, this kind of substance continues to enter the blood vessels, which will make the penis blood more narrow and aggravate impotence.
In addition, the number of sperm in the semen of male smokers has also been greatly reduced, and abnormal sperm beyond the normal range appears. Its sperm survival rate decreases and the vitality is reduced, which is one of the reasons for male infertility.
