Erectile Dysfunction

Meta-analyses suggest that the combination of testosterone and PDE5 inhibitors yields more effective results, but in noncontrolled versus controlled studies.

The vacuum constriction device is another excellent non-surgical treatment option. This system uses a plastic cylinder that is placed over the penis; a small pump is then used to create negative pressure, which acts to “pull” blood into the penis – producing an erection. A rubber band is then applied to the base of the penis, so that blood is trapped in the erect penis to sustain the erection until the band is removed. Penile implant surgery is always an option for men who aren’t happy with other treatments. We can do most penile implant procedures on an outpatient basis with a relatively short recovery period.

Penis pumps, surgery and implants

Caverject® is one popular form of treatment. The therapy involves medication that is directly injected into the penis to produce an erection. After all the information regarding the patient’s status has been gathered, the various options for management of erectile dysfunction (ED) can be discussed. It is best to include the patient’s partner in this discussion. [1] One of the most difficult aspects of treatment is teaching men that sex entails more than simply achieving an erection. However, adverse effects, especially in older frail men, require consideration.

Replacement androgens are available in the following four forms: Oral therapy is rarely used; of the available approaches, it is the least effective and the most likely to be associated with hepatotoxicity, even though the risk is relatively small.

Frequently Asked Questions (FAQs) About Erectile Dysfunction

In current practice, PDE5 inhibitors are the most commonly used treatment for ED. Sildenafil was the first in this series of PDE inhibitors; avanafil is the newest, having been approved by the US Food and Drug Administration (FDA) in 2012. In a fildena extra power 150 mg study of 390 men with diabetes and erectile dysfunction, avanafil was found to be a safe and effective treatment as early as 15 minutes and more than 6 hours after dosing. Guidelines from the American Urological Association (AUA) recommend offering PDE5 inhibitors as first-line therapy for ED unless the patient has contraindications to their use (eg, concurrent organic nitrate therapy). The AUA notes that insufficient evidence exists to support the superiority of any one of these agents over the others.

Q How is erectile dysfunction diagnosed?

[1] European guidelines suggest that the choice of drug (short- versus long-acting) depend on the frequency of intercourse (occasional use or regular therapy, 3-4 times weekly) and the patient’s personal experience. The AUA warns that PDE5 inhibitors can cause mild transient systemic vasodilation, which may be aggravated by alpha-blocking agents. Consequently, the guidelines advise that vardenafil and tadalafil, at any dose, and sildenafil at 50 mg and 100 mg doses should be administered with caution in patients who are taking alpha blockers. In patients with ED that is refractory to therapy with oral PDE5 inhibitors, one of these agents can be combined with an injection of prostaglandin E1 (PGE1; alprostadil). [3] Gutierrez et al demonstrated that this combination was more effective than either one alone. Parenteral therapy is the approach most likely to restore androgen levels to the reference range, but it requires periodic injections (usually every 2 weeks) to sustain an effective level. Measurement of peak and trough levels can help avoid symptomatic troughs and supernormal peak levels, though such measurement is rarely done in clinical practice.

• Use of herbal supplements like ginseng or L-arginine.
• Shockwave therapy to stimulate blood vessel growth.
• Platelet-rich plasma (PRP) injections for regenerative effects.
• Acupuncture as a complementary therapy.

Typically, a level is obtained 1 week after an injection.

Oral Medication

[89] The combination of a PDE5 inhibitor with intraurethral PGE1 has also proved successful. Men who present with diminished libido and ED may be found to have low serum testosterone levels (hypogonadism). Hormone replacement may benefit men with severe hypogonadism and may be useful as adjunctive therapy when other treatments are unsuccessful by themselves. Libido and an overall sense of well-being are likely to improve when serum testosterone levels are restored to the reference range. [90, 91, 92, 93, 94, 95] However, a meta-analysis by Corona et al found that the positive effect of testosterone therapy on erectile function and libido was significance only in randomized controlled trials partially or completely supported by pharmaceutical companies. Weekly injections using lower doses can be used to minimize the wide swings in blood levels noted with less frequent dosing.

Penile Injections

[79] Treatment with sustained-release bupropion proved effective in a phase II, randomized, double-blind, parallel-group, placebo-controlled trial involving 80 men with sexual dysfunction that emerged during methadone maintenance therapy. Of the patients receiving bupropion, 58.3% reported that their sexual function was "much/very much improved" compared with 27.7% of those receiving placebo. Many patients with ED also have cardiovascular disease—not surprisingly, given that the two disorders have a common etiology. Treatment of ED in these patients must take cardiovascular risks into account. Sexual activity, in and of itself, increases the chances of ischemic events and myocardial infarction (MI) because of the exertion and sympathetic activation that may accompany it.

What are the side effects of ED pills?

The absolute risk of MI during sexual activity and for 2 hours afterward is only 20 chances per million per hour in post-MI patients and is even lower in men without a history of MI. The Princeton Consensus Panel has produced guidelines for managing ED in patients with cardiovascular disease. [81, 10] The panel advises that a man with ED and no cardiac symptoms should be considered to have cardiac or vascular disease until proven otherwise. ED patients should be assessed and categorized as high-, intermediate-, or low-risk. Risk-factor modification, including lifestyle interventions (eg, exercise and weight loss) is strongly encouraged for ED patients with cardiovascular disease. Skin patches deliver a sustained dose and are generally accepted by patients.

Testosterone gels are available for daily topical use to treat male hypogonadism and have the advantage of minimizing the peaks and troughs associated with the use of injectable agents.

What Lifestyle Changes Can Help With Erectile Dysfunction?

The task of the physician is to identify which treatment would be most appropriate and most likely to have long-term success. To do that, the physician must take the time to understand the patient’s problem and be knowledgeable about the available options. Enough options are available that every man who wants to be sexually active can be, regardless of the etiology of the problem. Sexual counseling if no organic causes can be found for the dysfunction Oral medications - Typically, phosphodiesterase type 5 (PDE5) inhibitors Where possible, drugs that may be contributing to ED should be discontinued. However, ED as a manifestation of hypogonadism from abuse of anabolic steroids can persist for months to years after cessation of steroid use.

Medication changes

Interim treatment for hypogonadism in such patients, while hypothalamic-pituitary-gonadal function recovers, has included judicious use of testosterone replacement therapy, human chorionic gonadotropin (hCG), and selective estrogen receptor modulators (eg, clomiphene). Hyperprolactinemia from antipsychotic medication, especially risperidone, has been associated with sexual dysfunction. Treatment has included dose reduction, drug holidays, adjunctive medication, and switching to another drug (eg, olanzapine); however, data to support any of those strategies are limited. [77] A small open-label study by Fujioi et al of adjunctive aripiprazole for patients with antipsychotic-induced hyperprolactinemia and sexual dysfunction reported a significant decrease in erectile dysfunction at week 24. The use of methadone for opioid replacement therapy has been associated with increased rates of ED. However, these gels require daily application and are relatively expensive.

• ED can be a sign of underlying cardiovascular disease.
• Early intervention can prevent long-term complications.
• Team approach involving urologists, psychologists, and cardiologists is beneficial.
• Patient education improves management and outcomes.

Implantation of longer-acting testosterone pellets has become increasingly popular.

• Be aware of medication interactions that affect ED.
• Incorporate stress reduction techniques.
• Use prescription medications only as directed.
• Consider combination therapies for complex cases.

The pellet is placed during an office visit. The advantage of this approach is the infrequency of pellet placement (only every 3-6 months).

Intra-cavernosal Injection

A study by Gupta et al supports the view that for men with cardiovascular risk factors, modifications in lifestyle along with pharmacotherapy are helpful in improving sexual function. Patients who have serious cardiac disease or exertional angina or are taking multiple antihypertensive medications should seek the advice of a cardiologist before beginning therapy with a PDE5 inhibitor. Nevertheless, several studies examining the cardiac effects of sildenafil and tadalafil have found no increased risk of cardiovascular events in comparison with placebo. [83, 84] No significant differences in the incidence of MI, myocardial ischemia, or postural hypotension has been reported. Angioplasty or stent placement may be used for ED due to focal atherosclerotic stenosis of arteries supplying the penis.

Sildenafil (Viagra)

In patients with ED due to veno-occlusive dysfunction, transcatheter embolization may be used to occlude venous leaks [4, 5, 6] An increasing array of medications is available to assist in the management of ED. New agents are still undergoing clinical testing, and more are in the early phases of development. Medications currently being developed include dopaminergic and melanocortin receptor agonists, second-generation phosphodiesterase 5 (PDE5) inhibitors, rho-kinase inhibitors, soluble guanylate cyclases, and maxi-k channel activators. For any medication to be effective, the physiologic components involved in the erectile process must be functional. Serious impairments render the medication either completely or partially ineffective. The use of exogenous androgens suppresses natural androgen production. Elevation of serum androgen levels has the potential to stimulate prostate growth and may increase the risk of activating a latent cancer.

• Sildenafil (Viagra) is the original and most widely known PDE5 inhibitor.
• Intracavernosal injection of papaverine (less common now).
• Proper storage of injection medications (refrigeration often required).
• Mindfulness during sexual activity to stay present and reduce anxiety.
• Regular prostate cancer screening for early detection and treatment.
• Penile prosthesis: three-piece inflatable is the most popular type.

Periodic prostate examinations, including digital rectal examinations, prostate-specific antigen (PSA) determinations, and blood counts (ie, complete blood count [CBC]), are recommended in all patients receiving supplemental androgens.
