Viagra and erectile dysfunction |
The physiological causes of erectile dysfunction include various kinds of metabolic and hormonal diseases, physical damage such as pelvic and penile injury as well as injury to the bladder, spinal cord, testicles and prostate, blood and blood vessel disorders; diseases that affect the nerves; brain disorders such as brain tumours and other kinds of brain damage, stroke and Parkinson's disease, etc. The psychological factors that cause erectile dysfunction include stress, fatigue, depression, guilt, performance anxiety, low self esteem, lack of interest in sex, boredom, low libido, conflicts within a relationship as well as confusion about one's sexual orientation. Erectile dysfunction can also be caused due to external factors such as excessive smoking and as a side effect of certain prescription medications. Most cases of impotence can be resolved at any age, however, enhanced awareness is needed. Many men have sought treatment and returned to normal sexual activity due to improved impotence treatments. Impotence and its complications have been traditionally treated by urologists specializing in problems occurring in the urinary tract. Most doctors recommend that impotence treatments should commence from the one that is least invasive and go on to treatment forms that are invasive. This means that you may be asked to cut back on medications that are likely to cause erectile dysfunction as a side effect as the first step to your treatment. Behaviour modification and other forms of psychotherapy are considered next. This is then followed by oral drugs, vacuum devices, locally injected medications and surgically implanted devices. In rare cases, patients may be required to undergo surgery involving the penile arteries or veins.
Viagra for impotence treatment:
Consisting of the active ingredient sildenafil citrate, Viagra is one of the most popular prescription medications used in the treatment of erectile dysfunction. This oral pill belongs to a class of medications known as PDE5 inhibitors and works by blocking the action of PDE5 - a chemical that is responsible for restricting the flow of blood to the penis and thus preventing a complete erection. PDE5 inhibitors such as Viagra help relax penile muscles and ease the flow of blood so that you get a satisfactory erection. Viagra needs to be taken about 30 minutes before intended sexual intercourse and its effects last for up to 4 hours in your body. The effects of Viagra generally disappear after sexual intercourse has been completed. However, contrary to popular misconceptions, Viagra is not an aphrodisiac and cannot work well in the absence of external sexual stimulation. |
