Scientific Facts: Man's penis becomes erect when one of his senses (sight, sound, taste, touch, or smell) is stimulated and he becomes aroused. His central nervous system sends nerve impulses that increase blood flow to his penis. As blood flows into the penis, the penis gets larger and harder. The blood vessels that drain blood from the penis are blocked enough so that blood stays in the penis, maintaining the erection.

Four things are needed to have a normal erection:

• An intact nervous system that receives external stimulus signals and sends arousal signals to the penis.
• An intact system of blood vessels (vascular system) to allow blood to flow in and out of the penis.
• Normal smooth muscle in the penis, which must relax so that the penis can fill with blood and enlarge.
• Valves in the blood vessels must close to keep blood in the penis so that it stays firm.

Damage to or problems with any of these things may lead to erectile dysfunction and poor erections.

Psychological factors also may affect normal erectile function.

Other factors that have been known to affect men's ability to develop and sustain powerful erections include:

* Smoking * Stress* Age* Decline in Testosterone levels* Obesity* Erectile dysfunction which may be of a physical or mental nature (sclerotic veins or too much stress and worries or a combination, etc)

Blood flow and erection problems

There are two spongy chambers along each side of the shaft of your penis. These chambers are called the Corpus Cavernosa. When you have an erection, the smooth muscle in these spongy chambers relaxes so that blood flows in through the penile arteries and the chambers fill with blood and expand. The expanded chambers press against the veins that would normally drain blood from the penis, trapping the blood inside and making the penis erect.

After ejaculation or when you are no longer sexually aroused, the arteries narrow, the veins expand, and the blood drains out. The penis becomes limp.

Problems with the blood vessels that supply blood to the penis or return blood from the penis can cause erection problems. These vascular problems may include: "Hardening of the arteries (atherosclerosis) in the penis. This may block blood flow into the penis or into the arteries that fill the penile arteries."

Side effects of medications that affect the blood vessels, such as some high blood pressure medications. " Leaking of blood from the veins in the spongy chambers in the penis.

Perfomaxx increases blood circulation into these spongy chambers, resulting in a ROCKHARD ERECTION.
