Erectile dysfunction (ED) is commonly known as "impotence". It is when a man is unable to have and maintain an erection. Erectile dysfunction tends to mainly affect men between the ages of 40 and 70 but can affect younger men too. It can often cause psychological and relationship problems. It affects 1 in 10 men in the world at some point.

ED can be treated using oral medicines known as phosphodiesterase type 5 (PDE5) inhibitors. These "Erection Pills", as theyre sometimes referred to, work by relaxing the blood vessels that feed the penis. This causes increased blood flow into the penis and Increased blood = Increased Hardness.
