Erectile dysfunction occurs when a man cannot or has difficulty achieving and maintaining an erection. It is also called ED or impotence. This is caused by a lack of necessary blood flow to the penis which is what creates an erection in the first place. About 30 million men in the United States of America have some form of erectile dysfunction. Erectile dysfunction also can be a thing that happens every once in a while but not all of the time. Erectile dysfunction can also be caused by underlying medical conditions such as the following: diabetes, obesity, spinal cord injury, depression, heart disease, high blood pressure, prostate cancer treatment, high cholesterol, etc.
Sildenafil is one of the main components of Viagra and it works by preventing a chemical in your body from acting. Sildenafil inhibits phosphodiesterase type-5. This then relaxes or widens the body’s blood vessels and improves blood flow to the penis when the person is exposed to sexual stimuli.
To get a prescription to Viagra you will have to start a conversation with your doctor. After men had the talk with their doctors, 80% of them were more relaxed and relieved that they had the conversation. In fact, more than 23 million men have already spoken with their doctor to see if Viagra was right for them. Talking to a doctor and getting a prescription for Viagra also helps protect you from getting counterfeit Viagra which may not be safe and are also illegal.
