Impotence, also known as erectile dysfunction, has causes that include psychological, neurogenic, vascular, endocrine, diabetic, anatomical, hormonal, and pharmacologic. The goal of the treatment is to achieve a full recovery, to achieve and maintain a firm erection hardness, so as to restore a satisfactory sex life. There is no such thing as the “best” medication, and it should be used according to the individual’s condition and in accordance with the doctor’s instructions. 1. General treatment: The precautions in life include lifestyle adjustments, quitting smoking and limiting alcohol, increasing physical activity in moderation, controlling body weight, reasonable diet, and supplementing Omega-3 fatty acids, antioxidants, and calcium in moderation, which can improve the endothelial function of the blood vessels and improve the erection function. 2. Medication: The most common method is oral medication, including type 5-phosphodiesterase inhibitors such as sildenafil and tadalafil, and androgen therapy, apomorphine, yohimbine, trazodone, and so on. 3. Physical therapy: It can also be combined with physical therapy, including vacuum erection device, low-energy extracorporeal shock wave therapy, cavernous vasoactive drug injection therapy (opium poppy, phentolamine, prostaglandin, etc.). 4. Surgery: If general treatment and medication are ineffective, surgery can be chosen to improve impotence completely with penile support implantation. The above drugs should be used under the guidance of doctors. It is recommended that patients go to regular hospitals in time to seek treatment, and strive for early recovery.
