Is erectile dysfunction due to psychological or physical factors? Healthy men have involuntary erections in the early morning and during REM sleep (a stage in the sleep cycle with rapid eye movements). Men with psychogenic erectile dysfunction (erectile dysfunction due to psychological factors such as stress and anxiety rather than physical factors) usually maintain these involuntary erections. Men with physical causes of erectile dysfunction (for example, atherosclerosis, smoking, and diabetes) usually do not have these involuntary erections. Surgery: There are different types of surgery. Implanted devices, known as prostheses, can restore erection in many men. These can come in different forms. For instance, paired rods can be inserted into the corpora cavernosa to enable the user to manually adjust the position of the penis. Alternatively, inflatable cylinders can be inserted inside the penis and expanded using pressurized fluid. In some cases doctors may attempt to repair blockages in damaged arteries. However, this usually only works if the blockages are not widespread. cialis online pharmacy A psychosocial examination using an interview and questionnaire may reveal psychological factors contributing to erectile dysfunction. The sexual partner also may be interviewed to determine expectations and perceptions encountered during sexual intercourse. Certain medications can alter the gonadal function, including thiazide diuretics, some seizure medications, long-acting oral opiate pain medications, antipsychotic medications, and oral steroids. Sildenafil (Viagra) was the first oral phosphodiesterase type 5 (PDE5) inhibitor approved by the FDA in the United States for the treatment of erectile dysfunction (it is not approved for women). Sildenafil inhibits PDE5, which is an enzyme that destroys cGMP. By inhibiting the destruction of cGMP by PDE5, sildenafil allows cGMP to accumulate. The cGMP in turn prolongs relaxation of the smooth muscle of the corpora cavernosa. Relaxation of the corpora cavernosa smooth muscle allows blood to flow into the penis resulting in increased engorgement of the penis. In short, sildenafil increases blood flow into the penis and decreases blood flow out of the penis. cialis online pharmacy buy viagra online no prescription viagra Some people have trouble speaking with their doctors about sex.
