If you are finding that you are unable to become erect or lose your erection too early, the most likely cause is ED.
However, pinpointing what is causing your ED symptoms isn't always an easy task. Anyone with a penis can experience difficulties maintaining an erection from time to time, especially during periods of heightened stress, depression, or sudden or significant changes to your lifestyle or diet.
If you are experiencing ED symptoms several times per week over a period of a month or two, it may be worth talking with your doctor.
ED can occur from a buildup of the phosphodiesterase type 5 (PDE5) enzyme that can impact blood flow and ultimately interfere with blood flow to the penis. If your doctor believes this is the cause of your symptoms, medications like Viagra or sildenafil — also known as PDE5 inhibitors — can work to block PDE5 from distributing blood flow.
