How An Erection Forms
The penis contains two chambers called the corpora cavernosa, which run the length of the organ (see below figure). A spongy tissue fills the chambers. The corpora cavernosa are surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa and is surrounded by the corpus spongiosum.

Erection begins with sensory or mental stimulation, or both. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the spaces. The blood creates pressure in the corpora cavernosa, making the penis expand. The tunica albuginea helps trap the blood in the corpora cavernosa, thereby sustaining erection. When muscles in the penis contract to stop the inflow of blood and open outflow channels, erection is reversed.

Erection Formation

 Arteries and veins penetrate the long, filled cavities running the length of the penis. The corpora cavernosa and the corpus spongiosum. Erection occurs when relaxed muscles allow the corpora cavernosa to fill with excess blood fed by the arteries, while drainage of blood through the veins is blocked.
How ErectionRx Will Help With Erections
Taken an hour or so before sexual activity, ErectionRx increases the concentration of natural chemicals in the penis that causes the blood vessels to dilate, which increases blood flow to the penis. ErectionRx does not cause “instant” or “automatic” erections but works in response to sexual stimulation. ErectionRx works to expand the blood vessels in the penis to help cause increased blood flow and penis size. ErectionRx is a safe, very effective, and completely noninvasive method for help with increasing the blood flow to the penis for the best possible erections.
