Order Viagra Prescriptions
Erectile Dysfunction, often shortened to ED, is when a man is unable to get or maintain an erection during sexual intercourse or arousal. This can be due to a number of causes but the primary reason is insufficient blood flow to the penis. An erection is the result of increased blood flow to the fleshy tissue of the penis causing the penis to become engorged. Men who suffer from erectile dysfunction often order Viagra prescriptions to help them achieve lasting erections.
Erectile dysfunction can be an uncomfortable or embarrassing experience for a man. It has been known to have strong psychological effects on men such as shame, or inadequacy. There are also societal connotations such as a loss of virulence or masculinity. There are a variety of reasons for erectile dysfunction such as high blood pressure, diabetes, high cholesterol or heart disease; it can also be due to psychological reasons. Although erectile dysfunction can affect men of all ages, age does play an important role when it comes to the frequency of erectile dysfunction. Men who are over sixty are four times more likely to be affected by erectile dysfunction than forty year olds.
