What is Erectile Dysfunction?
Erectile Dysfunction (ED) is a medical condition where a man is unable to achieve or maintain an erection sufficient for satisfactory sexual intercourse, or to achieve orgasm.
Erectile Dysfunction is common and affects a wide range of men worldwide, including many men in Europe. It's the most common form of sexual dysfunction, affecting around 5 in 10 men in the UK alone. It is also one of the most common causes of sexual health issues.
While many men don't experience sexual health problems due to erectile dysfunction, some may experience an increase in symptoms, such as reduced interest, difficulty achieving orgasm, and problems with ejaculation.
Erectile Dysfunction can also be treated with medication or counselling and can include lifestyle changes such as reducing smoking and reducing alcohol consumption. Treatment usually requires sexual stimulation and involves an injection of a medication known as a phosphodiesterase 5 inhibitor (PDE5i).
The medication, known as Viagra Connect, works by increasing blood flow to the penis, which leads to an erection. Erectile Dysfunction can be a symptom of underlying health problems such as heart disease, diabetes, high blood pressure, and cholesterol levels.
Men with erectile dysfunction may also experience other medical conditions, such as prostate cancer. However, ED is not an uncommon side effect of medication such as Viagra Connect.
