Contrary to popular belief, Viagra doesn’t give you an erection. By blocking an enzyme that reduces the effectiveness of nitric oxide, Viagra gives the body a chance to actually get an erection from sexual stimulation.
Viagra works by increasing the effectiveness that nitric oxide has on relaxing the muscles in the penis when a man is stimulated sexually. This relaxation creates a better blood flow to the penis. This increased blood flow allows erection to occur, in addition, it maintains that erection for longer periods of time.
Male impotence is a condition where the penis doesn’t become erect, although your brain and body are signaling that sexual stimulation is occurring. Losing your erection during sex is also a type of ED.
There are many causes for erectile dysfunction and most men experience male impotence or ED at least once during their lives. Causes can include physical, emotional or mental problems or stresses.
• Physical causes include drug use, including prescription drugs for diabetes or high blood pressure.
• Work-related stress and depression are two examples of emotional causes.
• Fear that male impotence can or will happen can be considered a mental cause. You can become so worried about your performance that you actually create the condition that you worry about.
Viagra functions as phosphodiesterase type 5 (PDE-5) blocker. PDE-5 is a naturally occurring enzyme. In simple terms, Viagra blocks or suppresses how the body reacts to PDE-5, and allows nitric oxide to relax the muscles in the penis. This relaxing increases the blood flow to the penis.
Note, however, that although the jokes about men being unable to get rid of their erection after taking Viagra are a staple of our times, without sexual stimulation, Viagra will have no effect on state of your erection. Viagra doesn’t cause the erection; it just allows your body to have one.
