Erectile dysfunction (ED) or impotence is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual activity.[1] A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but can often be helped.
Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of PDE5 inhibitor drugs (the first of which was sildenafil or Viagra). The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina; it is now mostly replaced by more precise terms, such as erectile dysfunction (ED).
Erectile dysfunction is characterized by the regular or repeated inability to obtain or maintain an erection. Surgical intervention for a number of conditions may remove anatomical structures necessary to erection, damage nerves, or impair blood supply. Penile erection is managed by two mechanisms: the reflex erection, which is achieved by directly touching the penile shaft, and the psychogenic erection, which is achieved by erotic or emotional stimuli. A useful and simple way to distinguish between physiological and psychological impotence is to determine whether the patient ever has an erection. Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue.
Tests such as the bulbocavernosus reflex test are used to determine if there is sufficient nerve sensation in the penis. It is normal for a man to have five to six erections during sleep, especially during rapid eye movement (REM). This test uses electromagnetic vibration to evaluate sensitivity and nerve function in the glans and shaft of the penis.
The cyclic nucleotide phosphodiesterases constitute a group of enzymes that destroy the cyclic nucleotides cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Extracorporeal shockwave therapy is a relatively new treatment for erectile dysfunction that is non-drug, non-surgical and without adverse side effects.
In a German study with 224 groin hernia patients, 23,2% of them mentioned preoperative sexual dysfunction related to the groin hernia. During the late 16th and 17th centuries in France, male impotence was considered a crime, as well as legal grounds for a divorce. Modern drug therapy for ED made a significant advance in 1983, when British physiologist Giles Brindley dropped his trousers and demonstrated to a shocked Urodynamics Society audience his papaverine-induced erection.[31] The drug Brindley injected into his penis was a non-specific vasodilator, an alpha-blocking agent, and the mechanism of action was clearly corporal smooth muscle relaxation. Gene therapy is being developed that would allow for weeks or months long effect, supporting erections. A study done at the Medical College of Georgia has found that venom from the Brazilian wandering spider contains a toxin, called Tx2-6, causes erections. Erectile dysfunction is a name that is used to explain the incapacity to get an erection and the ability to sustain that erection in order to complete the intercourse. Vasculogenic etiologies represent the largest group, with arterial or inflow disorders being the most common.
Extracorporeal shock wave therapy (ESWT), presently being used in the handling of urinary stones, Cardiology, Wound Healing, Neurology, Plastic Surgery.


With this ESWT, it is now possible to ascertain a rapid, effective and affordable outpatient treatment that can be put into use as many times as required without any side-effects. The process is most often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. The study of erectile dysfunction within medicine is covered by andrology, a sub-field within urology. While these two causes have not been proven they are likely suspects as they cause issues with both the blood flow and nervous systems. Erectile dysfunction is a common complication of treatments for prostate cancer, including prostatectomy and destruction of the prostate by external beam radiation, although the prostate gland itself is not necessary to achieve erection. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. Some blood tests are generally done to exclude underlying disease, such as hypogonadism and prolactinoma.
If never, the problem is likely to be physiological; if sometimes (however rarely), it could be physiological or psychological. The physician squeezes the glans (head) of the penis, which immediately causes the anus to contract if nerve function is normal. It gives a measurement of the vascular pressure in the corpus cavernosum during an erection. Saline is infused under pressure into the corpus cavernosum with a butterfly needle, and the flow rate needed to maintain an erection indicates the degree of venous leakage.
Magnetic resonance angiography uses magnetic fields and radio waves to provide detailed images of the blood vessels. Phosphodiesterases exist in different molecular forms and are unevenly distributed throughout the body.
It is the same therapy as used in orthopedics, urology and cardiology and which at higher energies is used to break up kidney stones, known as lithotripsy. This type of device is sometimes referred to as penis pump and may be used just prior to sexual intercourse.
It is significant to bear in mind that every male will some time or the other experience the irregular bedroom slump and at times for many nights in a line. Shock waves are being used for treating of poor blood flow in Erectile Dysfunction problems. This treatment is very good and provides amazing results as far as erectile dysfunction is concerned.
Inspite of his excellent surgical expertise after performing & assisting more than 250 renal transplants and 200 penile implant surgeries, because of his dedication towards Andrology chose to this field and established this one stop solution for all mens problems a€?THE ANDROCAREa€?. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.
Erectile dysfunction can have severe psychological consequences as it can be tied to relationship difficulties and masculine self-image. Impotence is also related to generally poor physical health, poor dietary habits, obesity, and most specifically cardiovascular disease such as coronary artery disease and peripheral vascular disease.


The current diagnostic and statistical manual of mental diseases (DSM-IV) has included a listing for impotence. A physician measures the latency between squeeze and contraction by observing the anal sphincter or by feeling it with a gloved finger inserted past the anus.
There are two methods for measuring changes in penile rigidity and circumference during nocturnal erection: snap gauge and strain gauge. The leaking veins responsible may be visualised by infusing a mixture of saline and x ray contrast medium and performing a cavernosogram.[19] In Digital Subtraction Angiography (DSA), the images are acquired digitally.
Doctors may inject a "contrast agent" into the patient's bloodstream that causes vascular tissues to stand out against other tissues.
One of the forms of phosphodiesterase is termed PDE5, and inhibiting PDE5 increases the amount of cGMP available in the blood supply to the penis, thus increasing blood flow. The indication for erectile dysfunction has been approved for use in Europe, most countries in the Middle East and South America as well as in Canada. Several types of FDA approved vacuum therapy devices are available with a doctor's prescription. This may be due to the reasons like fatigue, illness, or having an argument with someone and even a bad day at work.
Stimulation of the penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. A significant proportion of men who have no sexual dysfunction nonetheless do not have regular nocturnal erections. The contrast agent provides for enhanced information regarding blood supply and vascular anomalies. When pharmacological methods fail, a purpose-designed external vacuum pump can be used to attain erection, with a separate compression ring fitted to the penis to maintain it. His radio programs recommended expensive goat gland implants and "mercurochrome" injections as the path to restored male virility, including operations by surgeon Serge Voronoff. Erectile dysfunction can only be analyzed when it is a regular feature - frequently for a phase of more than 2 weeks. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. These pumps should be distinguished from other penis pumps (supplied without compression rings) which, rather than being used for temporary treatment of impotence, are claimed to increase penis length if used frequently, or vibrate as an aid to masturbation. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems.[18] Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light.
