What is Erectile Dysfunction?

Erectile Dysfunction (ED), also known as impotence, is the inability to achieve and maintain an erection that is sufficient for satisfactory sexual intercourse.

Erectile Dysfunction is a very common condition, particularly in older men. It’s estimated that half of all men between 40 and 70 years of age will experience ED at least once.

Erectile Dysfunction isn’t the same for all men. Some men aren’t able to get an erection at all. Others can get an erection, but it’s not hard enough for sex, or the erection is lost either before or during sex.

Most men with Erectile Dysfunction can significantly improve their erections with the correct treatment. And better erections can mean better sex and a more fulfilling love life.

Which Treatment is Best?

There are a variety of treatments for Erectile Dysfunction and the main methods are outlined below. Not all treatments will be suitable for all men so it’s important to know the range of options available before starting treatment.


Tablets are the most common and popular treatment for Erectile Dysfunction. They work by increasing the flow of blood to the penis during sexual intercourse. ED tablets belong to a class of drugs known as PDE-5 inhibitors which includes Viagra, Sildenafil, Cialis, Levitra and Spedra. All of these drugs require normal sexual stimulation in order for the treatment to work. Erectile Dysfunction tablets normally start to take effect within 15-45 minutes and remain effective for up to 12 hours.


Tablets are not effective for all people and injections such as Caverject are one of the main alternatives. Caverject is injected into the base of the penis to stimulate an erection. Caverject normally starts working within 5-20 minutes and lasts about an hour. Some products include


For those who don’t want to administer injections, Muse may be a better option. Like Caverject, Muse contains Alprostadil as the active ingredient and is administered by inserting a small pellet into the penis.


A new alternative is Vitaros erection cream, which also contains Alprostadil. Vitaros is applied to the hole in the penis and can be an effective alternative if you have problems with erection tablets or the other methods described above.
