An Update of the International Society of Sexual Medicine's Guidelines for the Diagnosis and Treatment of Premature Ejaculation (PE)

INTRODUCTION In 2009, the International Society for Sexual Medicine (ISSM) convened a select panel of experts to develop an evidence-based set of guidelines for patients suffering from lifelong premature ejaculation (PE). That document reviewed definitions, etiology, impact on the patient and partner, assessment, and pharmacological, psychological, and combined treatments. It concluded by recognizing the continually evolving nature of clinical research and recommended a subsequent guideline review and revision every fourth year. Consistent with that recommendation, the ISSM organized a second multidisciplinary panel of experts in April 2013, which met for 2 days in Bangalore, India. This manuscript updates the previous guidelines and reports on the recommendations of the panel of experts. AIM The aim of this study was to 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 A comprehensive literature review was performed. RESULTS This article contains the report of the second ISSM PE Guidelines Committee. It offers a new unified definition of PE and updates the previous treatment recommendations. 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. We again recommend that these guidelines be reevaluated and updated by the ISSM in 4 years.

An evidence-based unified definition of lifelong and acquired premature ejaculation: Report of the second international society for sexual medicine Ad Hoc committee for the definition of premature ejaculation

INTRODUCTION The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. AIM The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. METHODS In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. RESULTS The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. CONCLUSION The ISSM unified definition of lifelong and acquired PE represents the first evidence-based definition for these conditions. This definition will enable researchers to design methodologically rigorous studies to improve our understanding of acquired PE.

Reliability and Validity of the Sexual Interest and Desire Inventory–Female (SIDI-F), a Scale Designed to Measure Severity of Female Hypoactive Sexual Desire Disorder

The Sexual Interest and Desire Inventory–Female (SIDI-F) is a 13-item scale developed as a clinician-administered assessment tool to quantify the severity of symptoms in women diagnosed with hypoactive sexual desire disorder (HSDD). The present investigation assessed the reliability and validity of the SIDI-F as a measure of HSDD severity. Results show that the SIDI-F exhibits excellent internal consistency, with Cronbachs alpha of 0.9. The validity of the SIDI-F as a measure of HSDD severity was confirmed by a number of observations. Women with a clinical diagnosis (Diagnostic and Statistical Manual of Mental Disorders [DSM-IV-TR; American Psychiatric Association, 2000]) of HSDD had significantly lower SIDI-F scores than women not meeting diagnostic criteria for any subtype of female sexual dysfunction and women diagnosed with female orgasmic disorder. There was a high correlation between scores on the SIDI-F and scores on the Female Sexual Function Index (FSFI; Rosen et al., 2000) and an interactive voice response version of the Changes in Sexual Functioning Questionnaire (CSFQ; Clayton, McGarvey, & Clavet, 1997; Clayton, McGarvey, Clavet, & Piazza, 1997), two validated measures that assess general female sexual dysfunction. In contrast, there was a poor correlation between SIDI-F scores and scores on a slightly modified Marital Adjustment Scale (Locke, Wallace, 1959; MAS), an assessment of general (nonsexual) relationship satisfaction. Taken together, the results of the present investigation indicate that the SIDI-F is a reliable and valid measure of HSDD severity, independent of relationship issues.

Bupropion sustained release (SR) for the treatment of hypoactive sexual desire disorder (HSDD) in nondepressed women.

This article describes the results of the first report of bupropion sustained release (SR) in nondepressed females with hypoactive sexual desire disorder (HSDD). Eligible females entered a 4-week, single-blind, placebo baseline phase. Subjects, all of whom did not respond to placebo, continued in a single-blind active treatment phase where they received bupropion SR for up to 8 additional weeks. We assessed HSDD by using investigator ratings of sexual desire and sexual functioning. Of the 51 evaluable subjects who entered the active treatment phase, 29% responded to treatment with bupropion SR. Bupropion SR was generally well tolerated. Pending the results of further study, bupropion SR may offer a treatment option for women with HSDD.This article describes the results of the first report of bupropion sustained release (SR) in nondepressed females with hypoactive sexual desire disorder (HSDD).

An Integrative Model

The purpose of the next three chapters is to present an integrative model for the treatment of chronic marital discord. Previous chapters have documented the absence of a comprehensive model for the conduct of marital therapy. In particular, it has been argued that the formation of theoretical schools and ideologies has hampered the clinician’s vision and range of permissible activities. Necessary linkages between alternative conceptual systems are absent and no clinically sophisticated theoretical model articulates with a data language. As stated previously, three principal conceptual dichotomies are felt to hinder integrative efforts within the field. Thus, the proposed model will attempt to establish linkages between present and past determinants of behavior, between observable behavior and internal psychological events, and between individual psychopathology and interpersonal behavioral systems. Such minimal linkages are necessary for the responsible treatment of marital disorders.

Evaluation of Sexual Functioning in Depressed Outpatients: A Double-blind Comparison of Sustained-release Bupropion and Sertraline Treatment

Sexual dysfunction is a frequently reported side effect of many antidepressants, including serotonin reuptake inhibitors. Bupropion, an antidepressant of the aminoketone class, is relatively free of adverse sexual effects. In a randomized, double-blind, multicenter trial, sustained-release bupropion (bupropion SR) and sertraline, a selective serotonin reuptake inhibitor, were found to be similarly efficacious in the treatment of outpatients with moderate to severe depression. This report describes the results of a double-blind comparison of the sexual side effect profiles of bupropion SR and sertraline. Two hundred forty-eight patients who had received a diagnosis of moderate to severe major depression were randomly assigned to receive treatment with bupropion SR (100-300 mg/day) or sertraline (50-200 mg/day) for 16 weeks. Eligible patients were required to be in a stable relationship and to have normal sexual functioning. Sexual functioning was assessed by the investigator at each clinic visit using investigator-rated structured interviews. A significantly greater percentage of sertraline-treated patients (63% and 41% of men and women, respectively) developed sexual dysfunction compared with bupropion SR-treated patients (15% and 7%, respectively). Sexual dysfunction was noted as early as day 7 in sertraline-treated patients at a dose of 50 mg/day and persisted until the end of the 16-week treatment phase. Four patients, all of whom were treated with sertraline, discontinued from the study prematurely because of sexual dysfunction. Given the similar efficacy of the two drugs in treating depression, bupropion SR may be a more appropriate antidepressant choice than sertraline in patients for whom sexual dysfunction is a concern.

Characteristics of Erectile Dysfunction as a Function of Medical Care System Entry Point

&NA; The scientific literature on the treatment of penile erectile dysfunction contains numerous contradictory reports on the relative frequency of organic causes of impotence and the treatment results of behavioral sex therapy. One explanation for these contradictory findings is the hypothesis that different investigators are studying different subsamples of the symptomatic population. This study investigated differences in characteristics of men who initially consulted a urologist with a complaint of impotence versus those who self‐referred themselves to a sexual dysfunction clinic. Self‐referred sexual dysfunction patients were more often white, more often had psychogenic etiologies to their difficulties, were more often of higher socioeconomic class, and had a much better response to psychological interventions. This study suggests that future studies concerning the etiology and treatment of impotence need to specify population characteristics such as referral source and screening criteria. It may be necessary to develop alternative treatment techniques for men who present to nonpsychiatric sources for help with psychogenic impotence.

Survey of Treatment Practices for Sexual Dysfunction(s) Associated with Anti-Depressants

There are many management strategies and antidotes available for sexual dysfunction associated with antidepressants available. However, only a few of these strategies and antidotes were tested in rigorous trials and most of them probably will not be rigorously tested. Surveying the prescribing practices of experts in this area provides another opportunity to evaluate these strategies and antidotes. The authors surveyed 29 (of 50) “expert” psychiatrists in the area of sexual dysfunction associated with antidepressants. Switching to another antidepressant, decreasing the dose of an antidepressant, and adding oral agents such as bupropion, phosphodiesterase-5 inhibitors, and some dopaminergic agents (dextroamphetamine, methylphenidate) and a testosterone patch in some dysfunctions (libido, orgasm) are management strategies most frequently used by the experts. The experts also consider these strategies as the most effective ones. These findings are compared with other studies and discussed with regard to the evidence from clinical trials.

Pharmacological agents causing sexual dysfunction

Abstract Reports of pharmacological agents affecting the human sexual response cycle are critically reviewed. Because of the paucity of adequately designed studies, few definitive statements can be made about pharmacological effects on human sexual functioning. Tentative evidence suggests that drugs with side effects of adrenergic blockade are associated with ejaculatory disturbances. Impotence appears to be associated with drugs possessing significant anticholinergic activity. Drug induced impotence and retarded ejaculation could both also be related to central dopamine blockade.
