Nearly 5 million men in South Africa suffers from erectile dysfunction, which is the difficulty in getting an erection or keeping an erection long enough to engage in sexual activity. This occurs when not enough blood is traveling to the penis. Erectile dysfunction can be caused from a physical condition such as, a disease or injury. Thoughts that lead to depression, anxiety, or worry can also cause erectile dysfunction. Some lifestyle and psychological factors can also cause erectile dysfunction. These factors include smoking, drinking, and stress, which can affect blood flow. There are some things you can do to help improve your chances of suffering from erectile dysfunction. These activities, or goals, include staying active, eat healthier, drink less alcohol, quit smoking, and find ways to reduce the unneeded stress in your life. Viagra is a drug based on sildenafil and it is used to help increase the blood flow to the penis. Viagra has been proven to work with men who suffer with erectile dysfunction. It usually takes around 30 – 60 minutes for Viagra to take effect and Viagra is usually only taken as needed. However, Viagra only works if you are sexually aroused. Viagra can be taken up to four hours before engaging in sexual activity. If an erection lasts longer than 4 hours after sex, seek emergency medical help immediately, as this can cause permanent injury. It is important to not take Viagra if you are currently under the influence of nitrates or street drugs, also known as poppers.
