The pellet is about the size of a grain of rice and dissolves to increase blood flow to the penis, creating an erection.

Entirely contained within the body, a pump fills two cylinders and.

Once activated you can maintain an erection as long as you desire. Penile implants require a surgical procedure by a physician, typically a urologist who has been trained and is skilled in penile prosthetics. There are three different types of penile implants: 3-piece inflatable implant, 2-piece inflatable implant, and a 1-piece bendable (malleable) implant.

Because each type of implant offers unique features, the risks and benefits should be discussed with the physician to help choose the most appropriate option.

Erectile dysfunction (ED) is one of the most common conditions affecting middle-aged and older men.

Nearly every primary care physician, internist and geriatrician will be called upon to manage this condition or to make referrals to urologists, endocrinologists and cardiologists who will assist in the treatment of ED.

This article will briefly discuss the diagnosis and management of ED. In addition, emerging concepts in ED management will be discussed, such as the use of testosterone to treat ED, the role of the endothelium in men with ED and treating the partner of the man with ED. Finally, future potential therapies for ED will be discussed.

Nearly every primary care physician, internist and geriatrician now understand cialis pills cvs that many older men retain an interest in sexual activity as they age.

Some primary care physicians think that sexual potency in older men is the norm, and that if it is lacking, it is ‘all in the head.’ This viewpoint has not been supported by current literature.

The Massachusetts Male Aging Study (MMAS) found that 52% of men between 40 and 70 years old reported having some form of erectile dysfunction (ED).1 The reality is that ED is a natural part of ageing and that the prevalence increases with age.

In the MMAS, they found that roughly 50% of men at 50 years old, 60% of men at 60 years old and 70% of men at 70 years old had ED. Thus, nearly all men who live long enough should develop ED.

Many factors can contribute to sexual

dysfunction

Aspects of an ageing man’s lifestyle and behaviour and androgen deficiency, most often decreasing testosterone levels, may affect sexual function as well.

A study of men between the ages of 30 and 79 years showed that 24% had testosterone levels below 300 ng/dL and 5.6% had symptomatic androgen deficiency.2. The percentage of men who engage in some form of sexual activity decreases from 73% for men aged 57–64 years to 26% for men aged 75–85 years.3 For some men, this constitutes a problem, but for others it does not. The aetiology for this decline in sexual activity is multifactorial and is in part due to the fact that most of the female partners undergo menopause at 52 years of age with a significant decline in their

One of the treatments for impotence discussed is a potion with 22 ingredients.4. Nearly 1000 years later, the Egyptian Papyrus Ebers, a medical Egyptian document dated 1600 BC, describes a cure for impotence in which baby crocodile hearts were mixed with wood oil and applied topically to the penis.4. In 1973, Dr Brantley Scott from Baylor College of Medicine reported on the implantable inflatable prosthesis that urologists still use today.5. The major breakthrough occurred in 1998 when sildenafil became the first oral drug to be approved to treat ED.4 This was followed by the use of tadalafil and vardenafil as similar phosphodiesterase-5 inhibitor oral medications for treating ED in 2003.4. Overview of physiological changes and other risk factors. As with most other organ system in the human body, changes and loss of function is normal consequence of the ageing process.

This is also true of the endocrine system, specifically the levels of testosterone production from the Leydig cells of the testicle.

Accompanying the decrease in testosterone is a decrease in erections which also has a component in decrease in the blood supply to the penis making erection not as frequent and not as rigid compared with a young man’s erectile function. Although these changes are in itself not life threatening, they can impact a man’s relationship with his partner, and also ED may be a harbinger of other undiagnosed conditions such as coronary artery disease (CAD), hypercholesterolaemia or diabetes mellitus.6.

ED is defined as the inability to achieve a full erection or the inability to maintain an erection adequate for sexual intimacy.

Other types of sexual dysfunction such as premature ejaculation and low libido may occur; however, the most common and disruptive problem in men is ED. Although most men

There are hundreds of medications that have the side effect of ED and/or decreased libido.

Examples of drugs implicated as a cause of ED include hydrochlorothiazides and beta-blocking agents. Medications used to treat depression, particularly the SSRIs such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Prozac Weekly, Sarafem), fluvoxamine (Luvox, Luvox CR), paroxetine (Paxil, Paxil CR, Pexeva) and sertraline (Zoloft), may also contribute to ED.9 Bupropion (Wellbutrin) which has a predominant effect on blocking the reuptake of dopamine is an antidepressant with lower incidence of ED.10 The side effects of 5ARIs occurring in fewer than 5% of patients can include gynaecomastia, ED, loss of libido and ejaculatory dysfunction.11. Men being treated for prostate cancer with treatments such as radical prostatectomy, radiation therapy or the use of Lutenizing hormone-releasing hormone (LHRH) agonists and antagonists can expect that ED may accompany these treatments.12. Smoking, excessive use of alcohol and illicit drugs are also associated with ED.13 A study in 2005 suggests that ED is not only more likely among men who smoked compared with those who never did, but that in

Bullet point: Ageing and comorbidities as well as polypharmacy factor greatly influence the development of ED.

The role of the endothelium in ED has been noted for a

number

The endothelial cell is now known to affect vascular tone and impact the process of atherosclerosis, and impacting ED, CVD and peripheral vascular disease.16.

The role of the endothelium in erectile function became clearer with the observation that the phosphodiesterase type 5 (PDE5) inhibitor, sildenafil, enhanced erectile function. Erection occurs with the release of nitric oxide (NO) from the vascular endothelial cells.17 The reduction in endothelial cell production of NO results in the negative impact on the smooth muscles in the corporal bodies and results in less relaxation of the smooth muscle cells with decrease in blood supply and resulting ED. A similar phenomenon is well known to impact the coronary arterial system resulting in CVD. It is important to understand that ED is frequently, if not usually, directly related to endothelial dysfunction, and that the release of NO by the vasculature of the penile arteries is directly related to the function of intact, healthy endothelium. In the face of endothelial dysfunction, the process of erection fails to occur in a normal fashion.16.

The association of ED, CVD and endothelial dysfunction.

The pathogenesis of organic ED is related to dysfunction of the endothelium. Endothelial cells can become injured through a variety of mechanisms, most of which cause oxidative stress on the tissues. Many of these causes of oxidative stress are related to lifestyle issues which lead to hypertension, diabetes and dyslipidaemia (figure 1). Endothelial cell dysfunction results in reduction of endothelium-dependent vasorelaxation as well as increased adhesion of leukocytes to the endothelium.

Endothelial cell injury then leads to a variety of sequelae, including ED, other types of vasoconstriction, atherosclerosis and thrombus formation.18. Download figure Open in new tab Download powerpoint.

Link between oxidative stress, endothelial dysfunction and ED. CVD, cardiovascular disease; ED, erectile dysfunction.

The association of CVD and ED was noted in 1997 as one analysed the results of the MMAS.

In this landmark study, 1709 men aged 40–70 years were enrolled between 1987 and 1989.

A follow-up some 10 years later revealed a striking relationship between ED and CVD. In this study, it became clear that the risk factors for ED were very similar to those of CVD, such as diabetes mellitus, smoking and dyslipidaemia.18.

Since endothelial dysfunction, CVD and ED are closely associated in epidemiological studies, the question for clinicians is whether to recommend the man presenting with ED undergo a cardiovascular (CV) evaluation.

Clearly, based on numerous studies, ED can be considered at least a ‘marker’ for possible further vascular disease or CVD.15 In their report, Vlachopoulos and

coworkers

Endothelial dysfunction is present in both CVD and ED, and is linked through the NO mechanism.

The authors note that PDE5 inhibitors improve endothelial function and have a salutary effect on both CVD and ED. Both ED and cardiac disease respond to modifications in lifestyle as well as pharmacologic manipulation.

These authors also report that the presence of ED gives the clinician an opportunity to assess CVD and prevention as well.20. Due to the fact that ED and CVD share many of the same risk factors, it is not surprising that there is a high incidence of ED in men who present with CVD.

A study by Montorsi et al found that ED was present in roughly 50% of patients with acute chest pain and confirmed CAD on angiography.21.

In this study, ED proceeded CVD in almost 70% of cases.

Similarly, many men with ED have been found to have pre-existing CVD. A study by Vlachopoulos et al evaluated the incidence of asymptomatic CVD in 50 men with ED.22 These authors found that 19% of men with ED had asymptomatic CVD.

Similarly, Mulhall and colleagues found that 20% of men presenting with ED and vascular insufficiency on penile duplex had asymptomatic CVD.23.

These findings suggest that patients who present with ED and CV risk factors should be evaluated for silent CVD and should undergo a thorough CV evaluation. Men with new onset ED and no signs or symptoms of CVD are at increased risk for experiencing a CV event in the subsequent 3–5 years.24. Men in their 40s with ED have a 50-fold increased risk of CVD and men in their 20s and 30s have a sevenfold increased CV risk.25. A meta-analysis of 36 744 men with ED in 12 prospective cohort studies found that the presence of ED significantly increased the risk of CVD, CAD, stroke and all-cause mortality, and the presence of ED was an independent risk factor for CVD. Ponholzer et al found that men with moderate to severe ED had a 65% increased relative risk for developing symptomatic CAD compared with men who did not have ED.26.

There were 4247 men with no ED at study entry; 2420 developed incident ED (defined as the first report of ED of any grade) over 5 years. Those men that developed ED had a 1.45-fold higher probability of experiencing a CV event compared with men who did not develop ED.27. The severity of ED has been correlated with the extent of CVD. Banks et al reported that the risk of future CV events increased progressively according to ED severity.28 This was shown in

On the horizon is gene therapy that would deliver genes that produce products or proteins that may not be functioning properly in the penile tissue of men with ED.

Replacement of these proteins may result in improvement in erectile function.

Experimental animal models have demonstrated improvement in erectile function with gene therapy. Human studies may also demonstrate success with this therapy.

Gene

therapy

The first stem cell study for the treatment of ED was published in 2004.

At this time, there is a total of 36 published basic studies assessing stem cell therapy for ED, with two clinical trials.

The mechanism of action of stem cells is to generate angiogenesis with subsequent increase in cavernosal smooth muscle cells within the corporal bodies.46.

Another potential new treatment consists of penile low-intensity shock wave lithotripsy. This consists of 1500 shocks twice a week for 3–6 weeks.

The purpose is to stimulate neovascularisation to the corporal bodies with improvement in penile blood flow and endothelial function. The use of low-intensity shock

Please answer true and false to the below statements. Men in their 40s with erectile dysfunction (ED) compared with men without a history of ED have an increased risk of developing cardiovascular disease (CVD) in 5 years.

Men presenting with ED should have consideration for a cardiovascular work-up as significant numbers of these men have occult or asymptomatic heart or vascular disease.

Endothelial dysfunction is more common in men with ED than in men with CVD. The most likely explanation for men developing ED prior to developing CVD is that the penile arteries are much smaller than the coronary arteries and the smaller penile arteries are likely to be occluded before the coronary arteries are significantly narrowed and become symptomatic.

All men receiving testosterone replacement need to have periodic measurement of haemoglobin and haematocrit to monitor for erythrocytosis.

False (both groups have endothelial dysfunction) Erectile Dysfunction: Management and Treatment.

The type of medical specialist who treats ED will depend on the cause of the problem. Based on your family's medical history, as well as your own medical history and current health, your doctor may treat you with oral medications (Viagra®, Levitra®, Cialis®).

If these options fail, you may be referred to a urologist who can assist with other non-surgical options such as vacuum device or injections or surgical treatment options.

If needed, your doctor may also refer you to a psychologist specializing in sexual dysfunction. ED can be treated in many ways, including: Oral medications. Discuss your options with your doctor to determine the best treatment for you.

The first step to

treating

What non-surgical treatments are there for erectile dysfunction (ED)? Education about sex, sexual behaviors, and sexual responses may help a man overcome his anxieties about sexual dysfunction. Talking honestly with your partner about your needs and concerns may also help to overcome many barriers to a healthy sex life.

Medications such as sildenafil (Viagra®), vardenafil (Levitra®), or tadalafil (Cialis®) may help improve sexual function in men by increasing blood flow to the penis.

Men who are on medicines that contain nitrates such as nitroglycerine should not take oral ED medications. The combination of nitrates and these specific medications can cause low blood pressure (hypotension).

The most common side effects of these medications are indigestion, nasal congestion, flushing, headaches and a temporary visual disturbance. Aids such as vacuum devices and penile constriction rings serve as erectile aids for some men. A vacuum constriction device (above) is a cylinder that is placed

over

The air is pumped out of the cylinder, which draws blood into the penis and causes an erection.
