Men who can’t get an erection can usually be cured, but the specifics need to be determined under a doctor’s supervision. The condition can be improved through general treatment, medication, physical therapy and surgery. 1. General treatment: Including lifestyle adjustment, quit smoking, limit alcohol, increase sports in moderation, weight control, reasonable diet, moderate supplementation of fatty acids, antioxidants, calcium, etc. can improve the endothelial function of blood vessels and improve erectile function. 2. Medication: the most common method is oral medication, including sildenafil, androgens, apomorphine, yohimbine, trazodone and so on. 3. Physical therapy: If the effect is not good, it can also be combined with physical therapy, including vacuum erection device, low-energy extracorporeal shock wave therapy, cavernous vasoactive drug injection therapy (poppycine, phentolamine, prostaglandin, etc.). 4. Surgery: If general treatment and medication are ineffective, surgery can be chosen to improve impotence with penile support implantation. The above drugs should be used under the guidance of a doctor, and it is recommended that patients go to a regular hospital in time to seek treatment and strive for early recovery.
