The American College of Physicians has issued recommendations for the treatment of erectile dysfunction. ACP strongly recommends that physicians initiate therapy with an oral phosphodiesterase type 5 (PDE-5) inhibitor in men who seek treatment for ED unless they have a contraindication to PDE-5 inhibitors, such as nitrate therapy. As for which PDE-5 inhibitor to use, ACP recommends that physicians base the choice on the individual preferences of patients including ease of use, cost of medication, and adverse effects profile.
"The evidence is insufficient to compare the effectiveness or adverse effects of different PDE-5 inhibitors for the treatment of ED because there were only a few head-to-head trials," explained the lead author of the guideline, Amir Qaseem. The guideline authors analyzed evidence gathered from 130 randomized controlled trials that evaluated oral PDE-5 inhibitors alone or combined. Treatment with a PDE-5 inhibitor resulted in statistically significant and clinically relevant improvements in sexual intercourse and erectile function in patients with ED, regardless of the cause (e.g., diabetes, depression, prostate cancer) or baseline severity.
ACP does not recommend for or against routine hormonal blood tests or treatment in the management of patients with ED because the evidence is inconclusive about the effectiveness in patients with low testosterone levels. Physicians should individualize decisions to measure hormone levels based on the clinical symptoms (e.g., decreased libido, premature ejaculation, fatigue, etc.) and physical findings (for example, testicular atrophy, muscle atrophy) that suggest hormonal abnormality.
Erectile dysfunction can be a persistent inability to achieve or maintain penile erection sufficient for satisfactory sexual performance, an inconsistent ability to do so, or a tendency to sustain only brief erections. These variations make defining Erectile dysfunction and estimating its incidence difficult. Estimates range from 15 million to 30 million in the U.S., depending on the definition used. Estimates from the National Health and Nutrition Survey suggested that the cost of treatment of erectile dysfunction in the U.S. could reach $15 billion if all men sought care.
Erectile dysfunction is a common disorder of male sexual function and affects all age groups especially individuals with advanced age, diabetes, vascular diseases, psychiatric disorders, and possibly hypogonadism (low testosterone). Erectile dysfunction may be caused by chronic diseases such as obesity, hypertension, dyslipidemia, cardiovascular disease, or smoking; medications; psychosocial factors; or hormonal abnormalities.
