As one of the “characteristics” of men, smoking is seen by most men as a symbol of manhood. However, did you know that smoking also has a variety of subtle effects on the human body, allowing men to experience the gradual process of nicotine eating away at a man’s sexuality in a slow development process. Scientific studies have found that smoking can induce erectile dysfunction. Acute damage The nicotine in cigarettes directly stimulates the body’s sympathetic nerves, causing them to secrete adrenaline and norepinephrine, causing the cavernous body of the penis to contract, resulting in an inability to get an adequate erection. Chronic damage The chronic damage of smoking on men’s sexuality mainly involves: 1. Affecting the regulation of penile blood vessels. Long-term smoking can harden and narrow the arteries of the penis, thus significantly reducing the blood supply to the penis; smoking can also cause an increase in the viscosity of the blood. 2, affect the neural regulation of the penile erection reflex. Long-term smoking still allows the sympathetic nerve to secrete adrenaline and norepinephrine, causing erectile dysfunction in the penis, and can also significantly reduce the content of nitric oxide (a substance that promotes penile erection). 3, so that men’s hormone (androgen) secretion is reduced. The toxic substances in cigarettes can destroy the interstitial cells in the testes, which are specialized in the production and secretion of androgens, which are the driving factors of men’s sexual desire and ability. In summary, smoking can induce erectile dysfunction and does so primarily through two pathways: acute and chronic damage. The men who are addicted to smoking should abstain or quit the habit, so as not to let smoking eat away at their sexuality and lose their “manly” features.
