Some people think that smoking can show the masculinity of men, which is a symbol of the male style.There are even legends that the sucking two or three cigarettes before sex can extend the time of orgasm and enhance the pleasure of sexual life.The reason is that smoking can improve the ability of high -level neural activity in the human body, excite the brain, thereby promoting sexual desire and enhancing sexual life and pleasure.In fact, this is nonsense.
Although smoke can stimulate the brain and excite it, it often causes the imbalance of the brain's excitement and suppression, and is not coordinated. As a result, short -term excitement and long -term suppression.Long -term smoking can stimulate the sympathetic nerves, produce excessive adrenaline and norepinephrine, which shrinks the smooth muscle in the penis sponge body. The penis cannot be congested, causing erectile dysfunction and affecting normal sexual life.
There are many pathogenic factors, but the most important thing is caused by insufficient blood supply to the penis.The penis is mainly composed of three sponge bodies. The sponge body is full of blood sinus, connected to the arterial branches. When the penis is erected, the arteries are expanded and a large amount of blood enters the blood sinus under the dominance of the nerves, which increases the volume of the penis and the texture is hard.Harm substances such as nicotine, carbon dioxide, and carine oil in tobacco can cause porridge -like porridge, increase blood viscosity, microcirculation disorders, causing blood vessel cavity to reduce and narrowing of blood vessels, which causes difficultyNot firm.
