Introduction Testosterone deficiency (TD), also known as hypogonadism, is a condition affecting a substantial proportion of men as they age. The diagnosis and management of TD can be challenging and clinicians should be aware of the current literature on this condition. Aim To review the available literature concerning the diagnosis and management of TD and to provide clinically relevant recommendations from the Fourth International Consultation for Sexual Medicine (ICSM) meeting. Methods A literature search was performed using the PubMed database for English-language original and review articles published or e-published up to January 2016. Main Outcome Measures Levels of evidence (LoEs) and grades of recommendations are provided based on a thorough analysis of the literature and committee consensus. Results Recommendations were given for 12 categories of TD: definition, clinical diagnosis, routine measurement, screening questionnaires, laboratory diagnosis, threshold levels for the biochemical diagnosis of TD, prostate cancer, cardiovascular disease, fertility, testosterone (T) formulations, alternatives to T therapy, and adverse events and monitoring. A total of 42 recommendations were made: of these, 16 were unchanged from the Third ICSM and 26 new recommendations were made during this Fourth ICSM. Most of these recommendations were supported by LoEs 2 and 3. Several key new recommendations include the following: (i) the clinical manifestations of TD occur as a result of decreased serum androgen concentrations or activity, regardless of whether there is an identified underlying etiology [LoE = 1, Grade = A]; (ii) symptomatic men with total T levels lower than 12 nmol/L or 350 ng/dL should be treated with T therapy [LoE = 1, Grade = C]; (iii) a trial of T therapy in symptomatic men with total T levels higher than 12 nmol/L or 350 ng/dL can be considered based on clinical presentation [LoE = 3, Grade = C]; (iv) there is no compelling evidence that T treatment increases the risk of developing prostate cancer or that its use is associated with prostate cancer progression [LoE = 1, Grade = C]; and (v) the weight of evidence indicates that T therapy is not associated with increased cardiovascular risk [LoE = 2, Grade = B]. Conclusion TD is an important condition that can profoundly affect the sexual health of men. We provide guidance regarding its diagnosis and management. Men with TD who receive treatment often experience resolution or improvement in their sexual symptoms and non-sexual health benefits. [ABSTRACT FROM AUTHOR]

Background: In fixed-dose studies, vardenafil 5, 10, and 20 mg improves erectile function in men with erectile dysfunction (ED). Here, the efficacy and tolerability of vardenafil when used in a flexible-dose regimen was assessed.Methods: In this multicenter trial, 323 patients randomly received vardenafil 10 mg or placebo. After 4 weeks, patients could switch to 5 or 20 mg (or corresponding placebo), or remain on 10 mg for an additional 4 weeks; dose-switching was optional for the last 4 weeks. Efficacy variables included the IIEF-EF domain score, GAQ, and percentage of positive responses to SEP2/SEP3 questions.Results: The IIEF-EF domain score significantly improved from a baseline of moderate ED (12.6–13.1) to mild ED in men on vardenafil (21.0–24.2) compared with placebo (13.7–15.6) at weeks 4, 8, 12, and last observation carried forward (LOCF) (p<0.005 vs. placebo). A significantly greater proportion of men receiving vardenafil at weeks 4, 8, 12, and LOCF reported improved erections (80–86% vs. 21–36% for placebo, p<0.005). Successful SEP2 rates increased after vardenafil, reaching 84% at weeks 8 and 12 vs. 49–53% receiving placebo (p<0.005 vs. placebo). Vardenafil improved successful SEP3 rates ranging from 58% to 74% compared to 22–34% for placebo. The most common adverse events, flushing and headache, were generally mild and transient.Conclusion: In this flexible dose study, vardenafil was well-tolerated, and produced clinically relevant improvements in erectile function in men with ED.

Introduction Treatment of erectile dysfunction is based on pharmacotherapy for most patients. Aim To review the current data on pharmacotherapy for erectile dysfunction based on efficacy, psychosocial outcomes, and safety outcomes. Methods A review of the literature was undertaken by the committee members. All related articles were critically analyzed and discussed. Main Outcome Measures Levels of evidence (LEs) and grades of recommendations (GRs) are provided based on a thorough analysis of the literature and committee consensus. Results Ten recommendations are provided. (i) Phosphodiesterase type 5 (PDE5) inhibitors are effective, safe, and well-tolerated therapies for the treatment of men with erectile dysfunction (LE = 1, GR = A). (ii) There are no significant differences in efficacy, safety, and tolerability among PDE5 inhibitors (LE = 1, GR = A). (iii) PDE5 inhibitors are first-line therapy for most men with erectile dysfunction who do not have a specific contraindication to their use (LE = 3, GR = C). (iv) Intracavernosal injection therapy with alprostadil is an effective and well-tolerated treatment for men with erectile dysfunction (LE = 1, GR = A). (v) Intracavernosal injection therapy with alprostadil should be offered to patients as second-line therapy for erectile dysfunction (LE = 3, GR = C). (vi) Intraurethral and topical alprostadil are effective and well-tolerated treatments for men with erectile dysfunction (LE = 1, GR = A). (vii) Intraurethral and topical alprostadil should be considered second-line therapy for erectile dysfunction if available (LE = 3, GR = C). (viii) Dose titration of PDE5 inhibitors to the maximum tolerated dose is strongly recommended because it increases efficacy and satisfaction from treatment (LE = 2, GR = A). (ix) Treatment selection and follow-up should address the psychosocial profile and the needs and expectations of a patient for his sexual life. Shared decision making with the patient (and his partner) is strongly recommended (LE = 2, GR = A). (x) Counterfeit medicines are potentially dangerous. It is strongly recommended that physicians educate their patients to avoid taking any medication from unauthorized sources (LE = 2, GR = A). The first seven recommendations are the same as those from the Third International Consultation for Sexual Medicine and the last three are new recommendations. Conclusion PDE5 inhibitors remain a first-line treatment option because of their excellent efficacy and safety profile. This class of drugs is continually developed with new molecules and new formulations. Intracavernosal injections continue to be an established treatment modality, and intraurethral and topical alprostadil provide an alternative, less invasive treatment option. [ABSTRACT FROM AUTHOR]

Introduction In 2014, the International Society for Sexual Medicine ( ISSM) convened a panel of experts to develop an evidence-based process of care for the diagnosis and management of testosterone deficiency ( TD) in adult men. The panel considered the definition, epidemiology, etiology, physiologic effects, diagnosis, assessment and treatment of TD. It also considered the treatment of TD in special populations and commented on contemporary controversies about testosterone replacement therapy, cardiovascular risk and prostate cancer. Aim The aim was to develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of diagnosis and management of TD for clinicians without expertise in endocrinology, such as physicians in family medicine and general urology practice. Method A comprehensive literature review was performed, followed by a structured, 3-day panel meeting and 6-month panel consultation process using electronic communication. The final guideline was compiled from reports by individual panel members on areas reflecting their special expertise, and then agreed by all through an iterative process. Results This article contains the report of the ISSM TD Process of Care Committee. It offers a definition of TD and recommendations for assessment and treatment in different populations. Finally, best practice treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with TD. Conclusion Development of a process of care is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to new insights into the pathophysiology of TD, as well as new, efficacious and safe treatments. We recommend that this process of care be reevaluated and updated by the ISSM in 4 years.

Abstract: An association between erectile dysfunction and cardiovascular disease has long been recognized, and studies suggest that erectile dysfunction is an independent marker of cardiovascular disease risk. Therefore, assessment and management of erectile dysfunction may help identify and reduce the risk of future cardiovascular events, particularly in younger men. The initial erectile dysfunction evaluation should distinguish between predominantly vasculogenic erectile dysfunction and erectile dysfunction of other etiologies. For men believed to have predominantly vasculogenic erectile dysfunction, we recommend that initial cardiovascular risk stratification be based on the Framingham Risk Score. Management of men with erectile dysfunction who are at low risk for cardiovascular disease should focus on risk-factor control; men at high risk, including those with cardiovascular symptoms, should be referred to a cardiologist. Intermediate-risk men should undergo noninvasive evaluation for subclinical atherosclerosis. A growing body of evidence supports the use of emerging prognostic markers to further understand cardiovascular risk in men with erectile dysfunction, but few markers have been prospectively evaluated in this population. In conclusion, we support cardiovascular risk stratification and risk-factor management in all men with vasculogenic erectile dysfunction. [Copyright &y& Elsevier]

ABSTRACT Introduction. With the worldwide increase in penile augmentation procedures and claims of devices designed to elongate the penis, it becomes crucial to study the scientific basis of such procedures or devices, as well as the management of a complaint of a small penis in men with a normal penile size. Aim. The aim of this work is to study the scientific basis of opting to penile augmentation procedures and to develop guidelines based on the best available evidence for the management of men complaining of a small penis despite an actually normal size. Methods. We reviewed the literature and evaluated the evidence about what the normal penile size is, what patients complaining of a small penis usually suffer from, benefits vs. complications of surgery, penile stretching or traction devices, and outcome with patient education and counseling. Repeated presentation and detailed discussions within the Standard Committee of the International Society for Sexual Medicine were performed. Main Outcome Measure. Recommendations are based on the evaluation of evidence-based medical literature, widespread standards committee discussion, public presentation, and debate. Results. We propose a practical approach for evaluating and counseling patients complaining of a small-sized penis. Conclusions. Based on the current status of science, penile lengthening procedure surgery is still considered experimental and should only be limited to special circumstances within research or university institutions with supervising ethics committees.

ABSTRACT Introduction. Erectile dysfunction (ED) impacts on both members of the couple. Female partners of men with ED are more likely to report reduced sexual quality of life than women whose partners do not have ED. Aim. To assess vardenafil efficacy in men with ED and determine the effects of treatment on their female partner's sexual quality of life. Methods. Study participants comprised men aged 18-64 years with ED and their female partners. Eligible men had ED of ≥6 months' duration and a female partner who was motivated to support their ED treatment. Eligible women had a total Female Sexual Function Index score >23.55, indicating absence of significant sexual dysfunction. Following a 4-week screening period, men were randomized to treatment with vardenafil 10 mg or placebo, which could be titrated to 20 or 5 mg after 4 weeks. Main Outcomes Measures. Primary efficacy variables were question 3 of the Sexual Encounter Profile questionnaire (SEP3) and the quality-of-life domain of the modified Sexual Life Quality Questionnaire (mSLQQ-QOL). Results. The intent-to-treat population included 343 couples, with 168 and 175 men receiving vardenafil or placebo, respectively. Vardenafil treatment significantly improved both erection maintenance and the female partners' sexual quality of life. Least squares (LS) mean SEP3 overall success rates after 12 weeks of treatment were 9.5 (baseline) vs. 67.2 (week 12) and 12.4 (baseline) vs. 24.2 (week 12) in the vardenafil and placebo groups, respectively ( P < 0.0001). In female partners, LS mean mSLQQ-QOL scores were 28.8 (baseline) vs. 68.2 (last observation carried forward [LOCF]) in the vardenafil group and 24.6 (baseline) vs. 40.5 (LOCF) in the placebo group ( P < 0.0001). Conclusions. Vardenafil treatment of men with ED improved both their erectile function and the sexual quality of life of their female partners.

Dapoxetine has been evaluated for the on-demand treatment of premature ejaculation (PE) in five phase 3 studies in various populations worldwide and has recently been approved in several countries. To present integrated efficacy and safety data from phase 3 trials of dapoxetine. Data were from five randomized, multicenter, double-blind, placebo-controlled studies conducted in over 25 countries. Men (N = 6,081) ≥18 years who met the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria for PE; four studies required a baseline intravaginal ejaculatory latency time (IELT) of ≤2 minutes. Dapoxetine 30 and 60 mg on demand (prn; 1-3 hours before intercourse) were evaluated for either 12 or 24 weeks in four studies; one study evaluated dapoxetine 60 mg daily (qd; included in safety assessments only) or prn for 9 weeks. End points included stopwatch-measured IELT, Premature Ejaculation Profile (PEP) items, clinical global impression of change (CGIC) in PE, and adverse events (AEs). Average IELT (mean [standard deviation], geometric mean [standard error]) increased from baseline (across groups, 0.9 [0.49] minutes, 0.8 [1.01] minutes) to a significantly greater extent with dapoxetine 30 (3.1 [3.91] minutes, 2.0 [1.03] minutes) and 60 mg (3.6 [3.85] minutes, 2.3 [1.03] minutes) vs. placebo (1.9 [2.43] minutes, 1.3 [1.02] minutes; P < 0.001 for all) at week 12 (geometric mean fold increase, 2.5, 3.0, and 1.6, respectively). All PEP items and CGIC improved significantly with both doses of dapoxetine vs. placebo ( P < 0.001 for all). The most common AEs included nausea, dizziness, and headache, and evaluation of validated instruments demonstrated no anxiety, akathisia, suicidality, or changes in mood with dapoxetine use and no discontinuation syndrome following abrupt withdrawal. In this diverse population, dapoxetine significantly improved all aspects of PE and was generally well tolerated. [ABSTRACT FROM AUTHOR]

Sexual health is an integral part of overall health. Sexual dysfunction can have a major impact on quality of life and psychosocial and emotional well-being. To provide evidence-based, expert-opinion consensus guidelines for clinical management of sexual dysfunction in men. An international consultation collaborating with major urologic and sexual medicine societies convened in Paris, July 2009. More than 190 multidisciplinary experts from 33 countries were assembled into 25 consultation committees. Committee members established scope and objectives for each chapter. Following an exhaustive review of available data and publications, committees developed evidence-based guidelines in each area. New algorithms and guidelines for assessment and treatment of sexual dysfunctions were developed based on work of previous consultations and evidence from scientific literature published from 2003 to 2009. The Oxford system of evidence-based review was systematically applied. Expert opinion was based on systematic grading of medical literature, and cultural and ethical considerations. Algorithms, recommendations, and guidelines for sexual dysfunction in men are presented. These guidelines were developed in an evidence-based, patient-centered, multidisciplinary manner. It was felt that all sexual dysfunctions should be evaluated and managed following a uniform strategy, thus the International Consultation of Sexual Medicine (ICSM-5) developed a stepwise diagnostic and treatment algorithm for sexual dysfunction. The main goal of ICSM-5 is to unmask the underlying etiology and/or indicate appropriate treatment options according to men's and women's individual needs (patient-centered medicine) using the best available data from population-based research (evidence-based medicine). Specific evaluation, treatment guidelines, and algorithms were developed for every sexual dysfunction in men, including erectile dysfunction; disorders of libido, orgasm, and ejaculation; Peyronie's disease; and priapism. Sexual dysfunction in men represents a group of common medical conditions that need to be managed from a multidisciplinary perspective. [ABSTRACT FROM AUTHOR]

Introduction. Over the past 20 years our knowledge of premature ejaculation (PE) has significantly advanced. Specifically, we have witnessed substantial progress in understanding the physiology of ejaculation, clarifying the real prevalence of PE in population-based studies, reconceptualizing the definition and diagnostic criterion of the disorder, assessing the psychosocial impact on patients and partners, designing validated diagnostic and outcome measures, proposing new pharmacologic strategies and examining the efficacy, safety and satisfaction of these new and established therapies. Given the abundance of high level research it seemed like an opportune time for the International Society for Sexual Medicine (ISSM) to promulgate an evidenced-based, comprehensive and practical set of clinical guidelines for the diagnosis and treatment of PE. Aim. Develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. Method. Review of the literature. Results. This article contains the report of the ISSM PE Guidelines Committee. It affirms the ISSM definition of PE and suggests that the prevalence is considerably lower than previously thought. Evidence-based data regarding biological and psychological etiology of PE are presented, as is population-based statistics on normal ejaculatory latency. Brief assessment procedures are delineated and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. Conclusion. Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. Therefore, it is strongly recommended that these guidelines be re-evaluated and updated by the ISSM every 4 years.

Introduction: Testosterone (T) deficiency (TD) may significantly affect sexual function and multiple organ systems., Aim: To provide recommendations and Standard Operating Procedures (SOPs) based on best evidence for diagnosis and treatment of TD in men., Methods: Medical literature was reviewed by the Endocrine subcommittee of the ISSM Standards Committee, followed by extensive internal discussion over two years, then public presentation and discussion with other experts., Main Outcome Measure: Recommendations and SOPs based on grading of evidence-based medical literature and interactive discussion., Results: TD is the association of a low serum T with consistent symptoms or signs. T level tends to decline with age. T modulates sexual motivation and erection. It also plays a broader role in men's health. Recent studies have established associations between low T, male sexual dysfunctions and metabolic risk factors. Though association does not mean causation, low T is associated with reduced longevity, risk of fatal cardiovascular events, obesity, sarcopenia, mobility limitations, osteoporosis, frailty, cognitive impairment, depression, Sleep Apnea Syndrome, and other chronic diseases. The paper proposes a standardized process for diagnosis and treatment of TD, and updates the knowledge on T therapy (Tth) and prostate and cardiovascular safety. There is no compelling evidence that Tth causes prostate cancer or its progression in men without severe TD. Polycythemia is presently the only cardiovascular-related adverse-event significantly associated with Tth. But follow-up of controlled T trials is limited to 3 years., Conclusions: Men with sexual dysfunctions, and/or with visceral obesity and metabolic diseases should be screened for TD and treated. Young men with TD should also be treated. Benefits and risks of Tth should be carefully assessed in older men. Prospective, long-term, placebo-controlled, interventional studies are required before screening for TD in more conditions, including cardiovascular diseases, and considering correction of TD as preventive medicine., (© 2012 International Society for Sexual Medicine.)

The Princeton Consensus (Expert Panel) Conference is a multispecialty collaborative tradition dedicated to optimizing sexual function and preserving cardiovascular health. The third Princeton Consensus met November 8 to 10, 2010, and had 2 primary objectives. The first objective focused on the evaluation and management of cardiovascular risk in men with erectile dysfunction (ED) and no known cardiovascular disease (CVD), with particular emphasis on identification of men with ED who may require additional cardiologic work-up. The second objective focused on reevaluation and modification of previous recommendations for evaluation of cardiac risk associated with sexual activity in men with known CVD. The Panel's recommendations build on those developed during the first and second Princeton Consensus Conferences, first emphasizing the use of exercise ability and stress testing to ensure that each man's cardiovascular health is consistent with the physical demands of sexual activity before prescribing treatment for ED, and second highlighting the link between ED and CVD, which may be asymptomatic and may benefit from cardiovascular risk reduction., (Copyright © 2012 Mayo Foundation for Medical Education and Research.

Introduction: Although the characteristics of premature ejaculation (PE) are established, the exact aetiology is largely unknown. Genetic, neurobiological, pharmacological, psychological, urological and endocrine factors have all been proposed. In addition PE and erectile dysfunction are often co-morbid., Aim: This article provides an overview of the proposed biological and psychological aetiologies of PE., Methods: Review of the literature., Main Outcome Measures: Current data on the pathophysiology of PE., Results: This review shows that most of the proposed biological and psychological aetiologies of PE are not evidence-based and/or that attempts to confirm them have given conflicting results. There are good data to support roles for genetic and psychological factors, either causal, or secondary to PE for the latter, in lifelong PE. Conversely, more evidence-based data support the responsibility of opioid substance withdrawal, prostatic inflammation or hyperthyroidism in some cases of acquired PE, in addition to a probable role of psychological factors., Conclusions: The determinants of PE are certainly complex and multifactorial, while each partner's reaction to the frustration caused by the sexual dysfunction may exacerbate or perpetuate it. It is important to understand, as far as possible, the aetiology in the individual patient to ensure appropriate assessment and treatment. It should be noted that identification of an aetiological factor does not necessarily mean the cause of the PE has been completely explained, and the patient may require a combination of treatment approaches., (2011 International Society for Sexual Medicine.)

Introduction: Addition of testosterone (T) may improve the action of phosphodiesterase type 5 inhibitors (PDE5-Is) in patients with erectile dysfunction not responding to PDE5-Is with low or low-normal T levels., Aims: To confirm this add-on effect of T in men optimally treated with PDE5-Is and to specify the baseline T levels at which such an effect becomes significant., Methods: A multicenter, multinational, double-blind, placebo-controlled study of 173 men, 45-80 years, nonresponders to treatment with different PDE5-Is, with baseline total T levels ≤ 4 ng/mL or bioavailable T ≤ 1 ng/mL. Men were first treated with tadalafil 10 mg once a day (OAD) for 4 weeks; if not successful, they were randomized in a double-blind, placebo-controlled design to receive placebo or a 1% hydroalcoholic T gel (50 mg/5 g gel), to be increased to 10 mg T if results were clinically unsatisfactory. Main Outcomes Measures.  Mean change from baseline in the Erectile Function Domain Score of the International Index of Erectile Function and rate of successful intercourses (Sexual Encounter Profile 3 question)., Results: Erectile function progressively improved over a period of at least 12 weeks in both the placebo and T treatment groups. In the overall population with a mean baseline T level of 3.37 ± 1.48 ng/mL, no additional effect of T administration to men optimally treated with PDE5-Is was encountered. The differences between the T and placebo groups were significant for both criteria only in the men with baseline T ≤ 3 ng/mL., Conclusions: The maximal beneficial effects of OAD dosing with 10 mg tadalafil may occur only after as many as 12 weeks. Furthermore, addition of T to this PDE5-I regimen is beneficial, but only in hypogonadal men with baseline T levels ≤ 3 ng/mL., (© 2010 International Society for Sexual Medicine.)
