Get startedAbout erectile dysfunction
Our Canadian medical team are nurse practitioners and physicians licensed and practicing in your province. All our prescribers are registered with their provincial college—you can verify their credentials anytime through the public registry.
Erectile dysfunction (ED) is a condition where a lack of blood flow or nerve stimulation affects you getting and maintaining erections. It can be caused by a range of physical and psychological conditions like stress, anxiety, or depression. ED could also be the first sign of other health conditions too, like cardiovascular disease and diabetes.
There are many causes of erectile dysfunction, and they can be both physical and mental. A common cause is reduced blood flow to the penis due to narrowed blood vessels. These narrowings can be caused by high blood pressure, elevated cholesterol levels, or smoking. Other potential causes include hypertension, diabetes, kidney disease, cycling for long periods of time, and certain medications.
At MedExpress, the treatments we prescribe for erectile dysfunction work by increasing blood flow to the penis. This is what helps you to achieve and maintain an erection when aroused.
