You may be wondering: what is an erection? What is the physiology of getting one? What are the common causes? And How do erections work? Read on to discover how the erection process works. It’s not as complicated as it sounds! This article covers the physiology of a male erection and the common causes and treatments.

Physiological process of getting an erection

Getting an erection is a complex process involving the nervous system, blood vessels, and hormones. This process begins in the brain and extends through the vascular system to the penis. The nerves produce a chemical response that triggers an increase in blood flow. Blood flow increases to fill the spongy chambers of the penis, which swells and becomes erection-ready. This process ends when the brain stops sending signals to the blood vessels, and the penis returns to its flaccid state.

What Is an Erection and How Does It Work

During the erection process, blood flows into the spaces in the penis. Several factors, including psychological and physical stimulation, can increase the amount of blood entering the penis. This process also causes a temporary decrease in blood exiting the penis. The blood swells, and the arteries and veins leading to the penis expand. The enlarged penis squeezes against the fibrous tissues surrounding the veins, resulting in an erection.

Several medications can affect erectile function. For example, certain medications for high blood pressure can interfere with the physiology of getting an erection. For those who have trouble achieving an erection, switching to another medication may be the best way to regain sexual function. Remember, though, that changing your medication requires the approval of a healthcare provider. Changing your medication can cause many problems and should be done under the supervision of a physician.

Common causes

Among the most common causes of inability to maintain an erection are certain medications and drugs. Specifically, some types of medications that contain female hormones can cause impotence. Cocaine can also affect erections. However, you should be aware that cocaine is dangerous for your sex life. To find out what can cause erection problems, consider talking with your doctor. There are several treatments available, including prescription medications.

If you’re experiencing difficulty sustaining an erection, you may have an underlying medical condition. Anemia is a condition in which your red blood cell count is lower than usual. This condition can lead to fatigue, which is not conducive to achieving a firm erection. Your healthcare provider will be able to determine if you’re suffering from anemia, which can also cause trouble maintaining an erection.

ED is often associated with other health issues, such as heart disease. Men often delay seeking treatment because they’re embarrassed to discuss their sexual problems. This delays the diagnosis of serious underlying health issues, including a heart disease. In addition to seeking treatment for ED, your physician can recommend lifestyle changes to improve your sex life. If you have been suffering from this condition for a long time, talk to your doctor about the cause of your problem so that it can be treated.


There are several different treatments available to treat an erection, and each of these options has its pros and cons. There are various options to consider, including injection therapy and medications. Medications, such as Viagra, Cialis, and Levitra, increase the blood flow to the penis, but the downsides of using these drugs can also be harmful to your health. Other treatments for an erection include surgery and injections.

A specialist in erectile dysfunction will often perform an ultrasound, which uses a wand-like device to produce a video image of the penis’ blood vessels. In some cases, this test will be combined with an injection of medications that will help produce an erection. Another option is a psychological examination, which screens for underlying medical conditions. Lastly, a doctor will assess any underlying health conditions that may contribute to the problem.

A doctor will be able to determine what type of physical illness may be affecting your erectile function. Generally, this is a symptom of an underlying illness, such as a heart condition, blood vessel disease, or diabetes. Hormone problems can also affect the blood flow to the penis. Blood tests can identify any hormonal imbalances that may be causing your erectile dysfunction.
