Does drinking too much coffee really affect male function? Does coffee lead to the change of male function?

It has become a habit for many people to drink coffee to refresh themselves. But they may not know that excessive consumption of caffeinated drinks such as coffee or cola can affect libido and affect erections in men.

Coffee is refreshing because the caffeine it contains stimulates the sympathetic nerves. Sympathetic and parasympathetic control of the human brain rise and fall each other: the former controls all people's activities during the day, and under the stimulation of the external environment, it will make people excited and exhilarated, while the latter specializes in sex-related activities such as nocturnal erections. It relaxes people. When the sympathetic nerve activity is frequent, the relatively weak parasympathetic nerve will be suppressed, with clinical manifestations of decreased libido and inhibition of erection.
