How Do Erections Work?
The process of arousal and achieving an erection is complex. In healthy men, you see something you like, and it goes up. Simple, right? Even when all systems are working well, arousal requires psychological and physical elements that most men don’t take the time to analyze. Achieving an erection involves the brain, circulatory system, hormones, nerves, and muscles. Any issues in these areas may mean you need to take erectile dysfunction pills for a little help.
Psychological Causes of ED
An erection requires sexual excitement, and that starts in the brain. Your brain, in addition to your spinal cord, makes up your central nervous system. The penis is completely controlled by the central nervous system. When sexual stimulation is present, the brain signals the excitatory nerves in the penis to release nitric oxide and acetylcholine, chemical messengers that signal the smooth muscles in the arteries of the penis to relax and fill with blood. 1
Mental health disorders such as depression and anxiety can disrupt brain function and lead to erectile dysfunction. Depression may arise from different factors, such as workplace disappointment, low self-esteem, or an indifferent outlook of the future. Anxiety can occur if you have experienced ED before and are worried it will happen again. Essentially, your sexual organs can’t fully perform if your brain isn’t functioning on all cylinders. With all that being said, psychological causes are often more interlinked with physical causes than you may realize. For example, depression may seem like a psychological cause, but the antidepressants prescribed to depressed men can interact with ED treatment and cause physical ED symptoms.
