Mechanical therapy is also effective and is especially well-accepted in men with stable partners. Vacuum-assisted erection devices are effective in creating erections in as much as 67% of cases. Vacuum pressure encourages increased arterial inflow, and occlusive tension rings discourage venous outflow from the penile corpus cavernosae. The penis placed inside the cylinder, a pump is used to produce a vacuum that pulls the blood into the penis. After the tension ring is slipped onto the base of the penis, the cylinder is removed. Erection lasts until the rings are removed. The one-time expense of this therapy is $120–300.
The penis is composed of three cylinders: two on the top, the corpora cavernosa and one on the bottom, the corpus spongiosum. All of these are involved in the process of an erection. The corpora cavernosa are composed of potential spaces that can distend with blood, causing rigidity of the penile shaft. The corpus spongiosum is important for rigidity of the glans of the penis. When aroused, stimulated chemicals are released from the nervous system (nitric oxide is one) that stimulate the arteries to the penis to relax and increase blood flow into the penis. These potential spaces, like a sponge, can expand when more blood flow comes in the penis. Each corpora cavernosa is surrounded by an outer coating the tunica albuginea. When the penis fills with blood, these potential spaces, the sinusoids, compress the veins in the corpora against the side of the tunica albuginea, thus preventing blood from leaving the penis. It is this compression of the veins that allows for the erection to become fully rigid.
Having learned a great deal more about erectile dysfunction including its risk factors and causes, you should be equipped to assess your own erectile function. If you have experienced erectile issues or you have some of the risk factors mentioned above, it may be worth making a trip to your doctor’s office. If you choose to seek help, give your doctor as much information as you can about your symptoms including their frequency and severity as well as the onset. With your doctor’s help, you can determine the best course of treatment to restore sexual function.
Yes, excessive alcohol intake can affect sexual function. Erectile dysfunction is more common in people who abuse drugs and alcohol. Lifestyle changes such as drinking less alcohol and quitting smoking may help improve sexual function. Chronic heavy alcohol consumption can affect erectile ability through altered hormone metabolism and nervous system involvement.

Nonsustained erection with detumescence after penetration is most commonly caused by anxiety or the vascular steel syndrome. In the vascular steel syndrome, blood is diverted from the engorged corpora cavernosae to accommodate the oxygen requirements of the thrusting pelvis. Questions should be asked regarding the presence or absence of nocturnal or morning erections and the ability to masturbate. Complete loss of nocturnal erections and the ability to masturbate are signs of neurological or vascular disease. It is important to remember that sexual desire is not lost with ED—only the ability to act on those emotions.
Erections are neurovascular events, meaning that nerves and blood vessels (arteries and veins) are involved in the process of an erection and all must work properly to develop a hard erection that lasts long enough. Erection begins with sexual stimulation. Sexual stimulation can be tactile (for example, by a partner touching the penis or by masturbation) or mental (for example, by having sexual fantasies, viewing porn). Sexual stimulation or sexual arousal causes the nerves going to the penis to release a chemical, nitric oxide. Nitric oxide increases the production of another chemical, cyclic GMP (cGMP), in the muscle of the corpora cavernosa. The cGMP causes the muscles of the corpora cavernosa to relax, and this allows more blood to flow into the penis. The incoming blood fills the corpora cavernosa, making the penis expand.
Once observed that the organic component of ED is the most important one in younger patients (Figure 2), the summarized evidence underlines that metabolic and CV risk must not be underestimated in younger men even when they are apparently healthy. In fact, it is particularly in these men that recognizing the presence of risk factors can help in changing life-style, thus really changing the natural history of metabolic and CV diseases. In older men the damage is often already established and the identification of further risk factors usually does not add information to the estimation of CV risk. ED is a symptom that can provide a chance for both the patients and physicians to unearth the presence of CV risk factors and improve both the quality and length of life of these men.

You might consider having a few drinks to get in the mood, but overindulging could make it harder for you to finish the act. Heavy alcohol use can interfere with erections, but the effects are usually temporary. The good news is that moderate drinking -- one or two drinks a day -- might have health benefits like reducing heart disease risks. And those risks are similar to erectile dysfunction risks.


Medications used in the treatment of other medical disorders may cause erectile dysfunction. If you think erectile dysfunction is caused by a medication, talk with your doctor about drugs that might not cause this side effect. Do not just stop taking a prescribed medication before talking with your health care provider. Common medications associated with erectile dysfunction are:
Describing the epidemiology of ED in young men requires, first of all, defining what it is meant by youth. While the definition of old age is matter of discussion and a precise threshold does not exist, the most shared definition in Western Countries is age above 65 years (http://www.who.int/healthinfo/survey/ageingdefnolder/en/). Considering that most of the epidemiological studies on general populations aimed at studying health changes with age, enrol men more than 40 years, it seems reasonable to define young age as below 40 years. Epidemiological studies on erectile function, which considered the prevalence of ED according to age bands, consistently find a significant increase with ageing. Advancing age remains one of the most important unmodifiable risk factors for ED (1). Studies on ED mostly involve middle-aged and older men, with younger aged men often overlooked. In a multi-centre worldwide study, involving more than 27,000 men from eight countries, Rosen et al. (2) showed an ED prevalence of 8% among men aged 20–29 years and 11% among those aged 30–39 years. Most of the studies involving younger men and conducting age-stratified analyses have been performed in Europe, where the prevalence of ED in men younger than 40 years ranges between 1% to 10% (3-10). The prevalence reported in these studies is highly variable due to different methodologies used in defining ED, population accrual, acquisition of data and choice of tools for investigating erectile function. A smaller number of studies on this topic have been conducted outside Europe. Both in Australia (11,12) and in America (13-15), the available information suggests a similar range of prevalence of ED among young subjects, with the same extent of variability among studies. According to these data, ED in younger men, although still not extensively studied and largely overlooked by the scientific community, is a quite common condition. In a recent study conducted in a Urology Clinic, it has been observed that one out of four men seeking medical care for ED was younger than 40 years (16). In our Sexual Medicine and Andrology Unit, established in an Endocrinology setting at the University of Florence, medical consultations for younger men are infrequent, with a prevalence of men aged less than 40 years at only 14.1% of more than 3,000 men complaining of ED. However, when considering the new referrals to our Unit during the last 6 years, we can notice a progressive increase in prevalence of men below 40 years seeking medical care for ED (Figure 1). According to these data, ED is becoming a common concern even among young men, and the clinical practitioner in sexual medicine must become aware of how to manage the problem and avoid underestimating a symptom. The identification of ED in a young man may potentially provide a great deal of useful information that can help improve their quality and even length of life.
Another common reason for failures of oral therapy is the absence of sexual or genital stimulation prior to attempting sexual intercourse. These medicines facilitate an erection by increasing blood flow to the penis, but they do not act as an aphrodisiac or as an initiator of the erection. A man who is not “in the mood” or does not have adequate physical stimulation will not respond with an erection.

What happens is that the blood vessels of the penis are rather small, and a small amount of plaque in the penile arteries is going to result in erectile dysfunction. You need more plaque before the person’s actually symptomatic from a heart problem, but they’re linked. And so when anybody, any man has an erectile issue, it’s incumbent upon the physician to make certain that their cardiac status is healthy.

Erectile dysfunction, often referred to as ED, is characterized by a persistent and recurring inability to achieve or maintain an erection sufficient for sexual intercourse. Psychological, physical and lifestyle issues can all cause ED, as can trauma to nerves and arteries. The incidence of erectile dysfunction increases with age, but young men can also experience it.

Combination therapy has proven effective for some men who don’t respond adequately to oral medicines. The idea is to use two drugs with different mechanisms of action for better results. Commonly, sildenafil is used in combination with pellets of alprostadil (synthetic prostaglandin E1) that are inserted into the urethra (the tube in the penis that carries urine from the bladder to the outside of the body). Alprostadil also increases the blood supply to the penis, but by different means.
With that said, the only data we’re going to focus on here are the results of large, nationally representative sex surveys because they offer the best source of information when it comes to trying to establish realistic prevalence rates and how they might have changed over time. Data from convenience samples of college students just aren’t reliable enough for these purposes.
Vacuum therapy devices have a few disadvantages. One must interrupt foreplay to use them. You must use the correct-size tension ring and remove it, to prevent penile bruising, after sustaining the erection for 30 minutes. Initial use may produce some soreness. Such devices may be unsuitable for men with certain bleeding disorders. In general, vacuum constriction devices are successful in management of long-term ED.
