The Science of an Erection

The Science of an Erection

The process of getting an erection seems simple- once a male is stimulated (psychologically or physically) blood flows to their penis and engorgement commences. However the science of an erection is in fact a complex series of events that involves numerous systems of the body.

How Does An Erection Work

It all begins with a stimulus. Usually this is from sexual stimulation. Firstly, the brain starts to release nitric oxide. Then, a precise series of neurotransmitters begin to communicate throughout the body. The nitric oxide stimulates the muscle enzyme triggering a messenger called cyclic guanine monophosphate (cGMP). This tells the blood vessels (that carry the blood to the penis) to increase with size while simultaneously decreasing the size of vessels carrying the blood. At this point, blood flows in at 8 times the normal rate. As the tissue expands, it presses against the veins preventing the blood to drain. The result is an erection.

Why It’s Unique

 No other part of the human body works as a draining system and then a high-pressure trapping system. The inside of the corpora cavernosa (the tissue forming the bulk of the penis) acts like a sponge. When these smooth muscles are relaxed and blood fills it, a pressure is created allowing massive expansion. The tunica albuginea is a trap door that allows all the blood in the corpora cavernosa to stay put, enabling an erection to maintain for some time.

Maintaining A Healthy Erection

 When this sequence of events is disrupted, either psychologically (nearly 20% of erectile dysfunction is of neurogenic origin) or physically (muscle, tissue, or vein response) there is potential for failure. If you are having trouble sustaining a healthy erection or find that your erections are unfilling to yourself or your partner, penile enhancement surgery is safe way to combat your sexual dissatisfaction.
