How does an erection actually happen?  Well the simple version is that blood enters the penis and the penis then becomes erect. In more medical jargon – the blood vessels of the corpora cavernosa relax and open up, blood rushes in through the cavernosus arteries to fill them. The blood then gets trapped under high pressure creating an erection.

An erection begins with sensory and mental stimulation. During sexual arousal, nerve messages begin to stimulate the penis. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand and creating an erection. The tunica albuginea (the membrane surrounding the corpora cavernosa ), helps to trap the blood in the corpora cavernosa, thereby sustaining erection. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and opening outflow channels.

Below is a video from Dr. Hossein Sadeghi-Nejad, which explains how an erection works:

The corpora are surrounded by a tough membrane called the tunica which limits the amount the corpora can expand. During an erection the blood flow to the penis increases by about 8-fold. It’s literally a case of blood rushing from other parts of the body – many would suggest predominantly from the head – into the penis.

There are many ways to improve the blood flow to the penis and help facilitate better erections. One of the quickest and safest ways is using a natural male enhancers that promotes improved genital circulation – usually from boosting nitric oxide levels in the body.
