Disorders of Ejaculation: An AUA/SMSNA Guideline.

PURPOSE: Men who ejaculate before or shortly after penetration, without a sense of control, and who experience distress related to this condition may be diagnosed with premature ejaculation (PE), while men who experience difficulty achieving sexual climax may be diagnosed with delayed ejaculation (DE). The experience of many clinicians suggest that these problems are not rare and can be a source of considerable embarrassment and dissatisfaction for patients. The role of the clinician in managing PE and DE is to conduct appropriate investigation, to provide education, and to offer available treatments that are rational and based on sound scientific data. MATERIALS AND METHODS: The systematic review utilized to inform this guideline was conducted by a methodology team at the Pacific Northwest Evidence-based Practice Center. A research librarian conducted searches in Ovid MEDLINE (1946 to March 1, 2019), the Cochrane Central Register of Controlled Trials (through January 2019) and the Cochrane Database of Systematic Reviews (through March 1, 2019). An update search was conducted on September 5, 2019. Database searches resulted in 1,851 potentially relevant articles. After dual review of abstracts and titles, 223 systematic reviews and individual studies were selected for full-text dual review, and 8 systematic reviews and 59 individual studies were determined to meet inclusion criteria and were included in the review. RESULTS: Several psychological health, behavioral, and pharmacotherapy options exist for both PE and DE; however, none of these pharmacotherapy options have achieved approval from the United States Food and Drug Administration and their use in the treatment of PE and DE is considered off-label. CONCLUSION: Disturbances of the timing of ejaculation can pose a substantial impediment to sexual enjoyment for men and their partners. The Panel recommends shared decision-making as fundamental in the management of disorders of ejaculation; involvement of sexual partner(s) in decision making, when possible, may allow for optimization of outcomes.

Clinical Outcomes of Periprocedural Antithrombotic Therapy in Ischemic Priapism Management.

BACKGROUND: Priapism is a urologic emergency consisting of a painful erection lasting greater than 4 hours; antithrombotic therapy (ATT) have recently been recommended as an adjunct in the treatment of ischemic priapism. AIM: To determine the short- and long-term outcomes of periprocedural ATT in the management of acute ischemic priapism. METHODS: A retrospective review of patients seen at the University of California, San Francisco, from 2008 to 2019 was carried out to identify those evaluated for acute priapism. Information regarding duration of priapism, etiology, treatment, periprocedural and postprocedural ATT type and dose, and follow-up data was collected. OUTCOMES: ATT use was the exposure of interest; outcome variables included priapism resolution, repeat episodes, long-term complications, and follow-up. RESULTS: 70 patients with at least 1 detailed record of an acute priapism episode between 2008 and 2019 were identified. Of the 70 patients who underwent management for an acute episode of priapism, 59 (84%) received intracavernous injection of phenylephrine with or without corporal aspiration. Of the 4 patients who received ATT at the same time as intracavernous injection, none had additional priapism episodes. In the 55 patients who did not receive immediate ATT, 22 (40%) required at least 1 shunting procedure. The 9 patients who received ATT concurrently with shunting experienced less recurrence than the 13 patients who did not receive ATT (11% vs 69%, respectively P = .012). There were no significant differences in long-term erectile dysfunction (P = .627), fibrosis (P = .118), genitourinary pain (P = .474), and urinary issues (P = .158) between those who received ATT and those who did not. CLINICAL IMPLICATIONS: Our findings suggest that ATT has a role in preventing priapism recurrence; we observed that long-term repeat priapism episodes are less frequent in those who received periprocedural ATT compared with those who did not and that ATT may especially reduce recurrence in cases when shunting was required STRENGTHS & LIMITATIONS: This is the first study looking at the clinical outcomes of periprocedural ATT in the management of ischemic priapism. It is limited by the fact that it is a single-center study, types of ATT were heterogenous, and the exact timing of priapism management could not be measured for everyone. CONCLUSION: In spite of its limitations, these preliminary findings are promising and warrant further exploration of the use of ATT in the management of ischemic priapism.

Anejaculation: Relevance to Sexual Enjoyment in Men and Women.

INTRODUCTION: Ejaculation and orgasm are important components of sexual response in men. Our understanding of both phenomena is limited. Anejaculation can be a source of substantial distress, even when procreation (ostensibly the only purpose of ejaculation itself) is not a priority. AIM: To present an opinion on male perceptions of ejaculation disorders (specifically anejaculation) based on a variety of data sources, including peer-reviewed literature. METHODS: A non-systematic review of literature on anejaculation and other impairments of ejaculatory and orgasmic response was conducted. Relevant articles were critically analyzed and reported MAIN OUTCOME MEASURE: An opinion is presented, based on existing data sources, on how and why ejaculation is deemed important to men and their sexual partners. RESULTS: The peer-reviewed literature on disorders of ejaculation is scant; existing reports oftentimes do not adequately distinguish between orgasm and ejaculation in assessment. Men's perceptions of ejaculation quality appear to be positively associated with satisfaction with sexual response, particularly regarding orgasm. Based on very limited data, female sexual partners of men appear to often (but not always) value the orgasmic experience of their partner; only a minority prioritize actual ejaculation. There is evidence that disorders of ejaculation may be particularly troublesome for men who have sex with men. CLINICAL IMPLICATIONS: The influence of medical conditions and treatments on ejaculation should be considered in the clinical context. Psychological adaptations and interventions may be of value in some cases. STRENGTHS & LIMITATIONS: Data on the clinical relevance of anejaculation outside the context of concomitant orgasmic dysfunction are sparse. Men's experience of orgasm is at least partially associated with ejaculation-specific variables; whether this association is mediated by psychological, physical, or a combination of factors remains unclear. CONCLUSIONS: Ejaculation, orgasm, and sexual satisfaction are closely intertwined but distinct phenomena. Shindel AW. Anejaculation: Relevance to Sexual Enjoyment in Men and Women.

Delayed Low-Intensity Extracorporeal Shock Wave Therapy Ameliorates Impaired Penile Hemodynamics in Rats Subjected to Pelvic Neurovascular Injury.

BACKGROUND: Erectile dysfunction (ED) caused by pelvic neurovascular injury (PNVI) is often refractory to treatment. In many cases, erectogenic therapy is administered in a delayed fashion. AIM: To evaluate penile hemodynamic effects and histologic changes associated with delayed low-intensity extracorporeal shock wave therapy (Li-ESWT) after PNVI ED in a rat model. We visualized images using immunofluorescence and 3-dimensional imaging of solvent-cleared organs (3DISCO), a novel imaging technique. METHODS: A total of 32 Sprague-Dawley male rats aged 12 weeks were divided equally into 4 groups: sham surgery as normal controls (NC), PNVI controls (PC), PNVI with very-low-energy Li-ESWT (PVL), and PNVI with low-energy Li-ESWT (PL). Bilateral cavernous nerve crush and internal pudendal bundle ligation were performed in the 3 PNVI groups. Li-ESWT was administered twice a week for 4 weeks in the PL and PVL groups starting at 4 weeks after PNVI. OUTCOMES: Intracavernous pressure (ICP) studies (normalized to mean arterial pressure [MAP]) were conducted in all subject animals. After testing, tissue was harvested for immunofluorescence staining and 3DISCO analysis. RESULTS: Mean ICP/MAP was lower in PC animals compared with NC animals (0.37 ± 0.03 vs 0.91 ± 0.03, respectively; P = .001). The ICP/MAP ratio was significantly higher in PVL and PL animals (0.66 ± 0.07 and 0.82 ± 0.05, respectively) compared with PC animals (P = .002 and .001, respectively). Detailed microstructures and trajectories of nerves and vessels were identified with immunofluorescence and 3DISCO. The PC group had lower density of nerves, axons, neuronal nitric oxide synthase-positive nerves, and Schwann cells in the dorsal penis. Animals in the PL group had significantly higher expression of all of these markers compared with PC animals. CLINICAL IMPLICATIONS: Li-EWST may have utility in the management of severe ED related to PNVI from severe pelvic injury or radical pelvic surgeries, even when administered in a delayed fashion. STRENGTH & LIMITATIONS: This study of a severe ED phenotype involved treatment administered in a delayed fashion, which is more consistent with how therapy likely would be delivered in a real-world clinical context. Moreover, because the treatment commenced at 4 weeks after injury, when nerve and tissue atrophy have already occurred, the results imply that Li-ESWT can be used for regenerative therapy. Additional studies on dose optimization and treatment interval are needed to inform the design of human clinical trials. CONCLUSION: Li-ESWT ameliorates the negative functional and histologic effects of severe pelvic neurovascular injury in a rat model system. 3DISCO provides high-resolution images of neuroanatomy and neural regeneration.

Erectile Dysfunction: AUA Guideline.

PURPOSE: The purpose of this guideline is to provide a clinical strategy for the diagnosis and treatment of erectile dysfunction. MATERIALS AND METHODS: A systematic review of the literature using the Pubmed, Embase, and Cochrane databases (search dates 1/1/1965 to 7/29/17) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of erectile dysfunction. Evidence-based statements were based on body of evidence strength Grade A, B, or C and were designated as Strong, Moderate, and Conditional Recommendations with additional statements presented in the form of Clinical Principles or Expert Opinions. RESULTS: The American Urological Association has developed an evidence-based guideline on the management of erectile dysfunction. This document is designed to be used in conjunction with the associated treatment algorithm. CONCLUSIONS: Using the shared decision-making process as a cornerstone for care, all patients should be informed of all treatment modalities that are not contraindicated, regardless of invasiveness or irreversibility, as potential first-line treatments. For each treatment, the clinician should ensure that the man and his partner have a full understanding of the benefits and risk/burdens associated with that choice.

A 17-Gene Genomic Prostate Score Assay Provides Independent Information on Adverse Pathology in the Setting of Combined Multiparametric Magnetic Resonance Imaging Fusion Targeted and Systematic Prostate Biopsy.

PURPOSE: Multiparametric magnetic resonance imaging and biopsy based molecular tests such as the 17-gene Oncotype DX® Genomic Prostate Score™ assay are increasingly performed to improve risk stratification in men with clinically localized prostate cancer. The prostate score assay was previously shown to be a significant independent predictor of adverse pathology findings at radical prostatectomy in men diagnosed by systematic biopsies only. Therefore, we investigated the ability of the prostate score assay to predict adverse pathology findings in the setting of magnetic resonance imaging guided prostate biopsy. MATERIALS AND METHODS: We identified men diagnosed with NCCN® (National Comprehensive Cancer Network®) very low, low or intermediate risk prostate cancer who underwent simultaneous multiparametric magnetic resonance imaging fusion targeted and systematic prostate biopsy with subsequent radical prostatectomy within 6 months. Prostate score assay testing was performed on biopsy tissue with the highest Gleason score. The primary outcome of the study was adverse pathology findings, defined as Gleason score 4 + 3 or greater disease and/or pT3+ at radical prostatectomy. Independent predictors of adverse pathology findings were determined in a multivariable model to adjust for clinical parameters. RESULTS: A total of 134 men were eligible for primary analysis. On univariable analysis the UCLA score, magnetic resonance imaging, prostate score assay results and biopsy Gleason score were significant predictors of adverse pathology findings. After multivariable adjustment prostate score assay values remained a significant predictor of adverse pathology results (prostate score assay per 20 U OR 3.28, 95% CI 1.74-6.62, p <0.001). A wide and overlapping distribution of prostate score assay results was seen across PI-RADS® (Prostate Imaging Reporting and Data System) version 2 scores. CONCLUSIONS: The prostate score assay result is an independent predictor of adverse pathology findings in patients who were diagnosed with very low, low or intermediate risk prostate cancer in the setting of multiparametric magnetic resonance imaging fusion prostate biopsy. This assay can be useful as an independent technology or an adjunct technology to multiparametric magnetic resonance imaging to individualize risk stratification of low and intermediate risk prostate cancer.

Perioperative Complications and Mortality in Patients with Urothelial Carcinoma and End-Stage Renal Disease Undergoing One-Stage Complete Urinary Tract Extirpation.

BACKGROUND: Complete urinary tract extirpation (CUTE) is a complex procedure with substantial risk for perioperative complications. The association between clinical characteristics and the risk of major postoperative complications has not been systematically investigated. OBJECTIVE: The aim of this study was to analyze the incidence and risks for major perioperative complications after CUTE. METHODS: Respective chart review of 81 patients with urothelial carcinoma (UC) who were treated with one-stage CUTE between January 2004 and December 2015. Fisher's exact test with Chi square and two-tailed t test were used in categorical and continuous variables, respectively. Univariable and multivariable logistic regression models were used to evaluate the probability of major complications. RESULTS: In this population, 53 (65.4%) patients had Clavien grade 0-2 complications ('no major complications') and 28 (34.6%) patients had Clavien grade 3-5 complications ('major complications'). Compared with the major complications group, patients in the no major complications group were younger, had lower Charlson Comorbidity Index (CCI), higher preoperative serum albumin, and shorter duration of hospitalization (p < 0.05 for all). Major complications were more common in low-volume surgeons (p = 0.002). On multivariate logistic regression analyses, CCI ≥ 5 (odds ratio [OR] 6.25, 95% confidence interval [CI] 1.42-27.47; p = 0.015) and surgery by a provider who performed three or fewer cases during the study interval (OR 13.4, 95% CI 2.20-80.89; p = 0.005) were independent predictors for major complications. CONCLUSIONS: High CCI should alert providers to increased probability of major complications, and warrant vigilant management after CUTE. Surgeon volume was inversely related to major postoperative complications.

Characteristics of Genital Dissatisfaction Among a Nationally Representative Sample of U.S. Women.

BACKGROUND: Female genital self-image is an important aspect of psychosocial and sexual health. The Female Genital Self-Image Scale (FGSIS) is a validated instrument that has been used to characterize women's level of genital dissatisfaction. AIM: In this report, we assess genital dissatisfaction using the FGSIS in a nationally representative sample of U.S. women. METHODS: We conducted a nationally representative survey of non-institutionalized adults aged 18-65 years residing in the United States. The survey included questions about demographics, sexual behavior, and the FGSIS. OUTCOMES: Demographic characteristics were found to significantly correlate to women's perceived genital dissatisfaction. RESULTS: In total, 3,372 women completed the survey and 3,143 (93.2%) completed the FGSIS. The mean age was 46 years, and there was broad representation across the United States in terms of age, education, and location. On bivariate analysis, women's genital dissatisfaction was significantly correlated to their age, race, location, and education. Women who were sexually active were less likely to report genital dissatisfaction than women who were not sexually active (76% vs 62%, respectively, P < .001). The frequency of sexual activity was negatively correlated with genital dissatisfaction (P = .002). Women who reported genital dissatisfaction were less likely than those who reported satisfaction to engage in receptive vaginal sex (83% vs 88%, respectively, P = .03). There were no other significant associations between genital dissatisfaction and types of sexual activity. On multivariate analysis, women were less likely to report genital dissatisfaction if they were older, of black race, had an education level of high school or above, and/or lived in the Northeastern or Midwestern United States. There was no association between genital dissatisfaction and relationship status or gender of sexual partner. CLINICAL TRANSLATION: Female genital dissatisfaction may be related to age, race, education, and geography. CONCLUSIONS: This is the first nationally representative sample of U.S. women focusing on genital and self-image and dissatisfaction. These data may not apply outside the United States. These data may help providers who provide information for women and manage concerns related to genital self-image. Rowen TS, Gaither TW, Shindel AW, et al. Characteristics of Genital Dissatisfaction Among a Nationally Representative Sample of U.S. Women. J Sex Med 2018;15:698-704.

Comparison of spinal cord contusion and transection: functional and histological changes in the rat urinary bladder.

OBJECTIVE: To compare the effect of complete transection (tSCI) and contusion spinal cord injury (cSCI) on bladder function and bladder wall structure in rats. MATERIALS AND METHODS: A total of 30 female Sprague-Dawley rats were randomly divided into three equal groups: an uninjured control, a cSCI and a tSCI group. The cSCI group underwent spinal cord contusion, while the tSCI group underwent complete spinal cord transection. At 6 weeks post-injury, 24-h metabolic cage measurement and conscious cystometry were performed. RESULTS: Conscious cystometry analysis showed that the cSCI and tSCI groups had significantly larger bladder capacities than the control group. The cSCI group had significantly more non-voiding detrusor contractions than the tSCI group. Both injury groups had more non-voiding contractions compared with the control group. The mean threshold pressure was significantly higher in the tSCI group than in the control and cSCI groups. The number of voids in the tSCI group was lower compared with the control group. Metabolic cage analysis showed that the tSCI group had larger maximum voiding volume as compared with the control and cSCI groups. Vesicular acetylcholine transporter/smooth muscle immunoreactivity was higher in the control than in the cSCI or tSCI rats. The area of calcitonin gene-related peptide staining was smaller in the tSCI group than in the control or cSCI groups. CONCLUSIONS: Spinal cord transection and contusion produce different bladder phenotypes in rat models of SCI. Functional data suggest that the tSCI group has an obstructive high-pressure voiding pattern, while the cSCI group has more uninhibited detrusor contractions.

Sexual Health in Undergraduate Medical Education: Existing and Future Needs and Platforms.

INTRODUCTION: This article explores the evolution and current delivery of undergraduate medical education in human sexuality. AIM: To make recommendations regarding future educational needs, principles of curricular development, and how the International Society for Sexual Medicine (ISSM) should address the need to enhance and promote human sexuality education around the world. METHODS: The existing literature was reviewed for sexuality education, curriculum development, learning strategies, educational formats, evaluation of programs, evaluation of students, and faculty development. MAIN OUTCOME MEASURES: The prevailing theme of most publications in this vein is that sexuality education in undergraduate medical education is currently not adequate to prepare students for future practice. RESULTS: We identified components of the principles of attitudes, knowledge, and skills that should be contained in a comprehensive curriculum for undergraduate medical education in human sexuality. Management of sexual dysfunction; lesbian, gay, bisexual, and transgender health care; sexuality across genders and lifespan; understanding of non-normative sexual practices; sexually transmitted infections and HIV, contraception; abortion; sexual coercion and violence; and legal aspects were identified as topics meriting particular attention. CONCLUSION: Curricula should be integrated throughout medical school and based on principles of adult learning. Methods of teaching should be multimodal and evaluations of student performance are critical. To realize much of what needs to be done, faculty development is critical. Thus, the ISSM can play a key role in the provision and dissemination of learning opportunities and materials, it can promote educational programs around the world, and it can articulate a universal curriculum with modules that can be adopted. The ISSM can create chapters, review documents, slide decks, small group and roleplay topics, and video-recorded materials and make all this material easily available. An expert consensus conference would be needed to realize these recommendations and fulfill them.

Effects of a dietary strawberry powder on parameters of vascular health in adolescent males.

Previous studies have shown that the intake of freeze-dried strawberry powder (FDSP) improves select markers of cardiovascular health in adults with cardiovascular risk factors; however, whether these improvements can be observed in at-risk adolescents is unknown. A randomised, double-blind, cross-over study enrolled twenty-five overweight or obese males, aged 14-18 years, to consume 50 g of a FDSP or a control powder, daily for 1 week. Before and after each test period, measures of microvascular function, plasma nitrate/nitrite, platelet reactivity and blood lipids were collected at baseline and acutely 1 h after FDSP intake. Acute plasma nitrate/nitrite levels increased 1 h after consuming the FDSP during Study Visit 1 before daily FDSP intake (P<0·001) and during Study Visit 2 after 1 week of FDSP intake (P<0·001) compared with control powder intake. As a group, fasting nitrate/nitrite levels did not significantly change after 1 week of control or FDSP intake. However, for those individuals where fasting nitrate levels increased after short-term FDSP intake compared with controls, an increase in reactive hyperaemia index (RHI) was observed (P=0·014), whereas RHI was unchanged in those individuals who did not have a significant increase in nitrate (P=0·396). Taken together, these data support the concept that strawberries can provide vascular health benefits to heavier adolescent males.

Phimosis with Preputial Fissures as a Predictor of Undiagnosed Type 2 Diabetes in Adults.

Diabetes is usually asymptomatic in its early stage. Early diagnosis may improve outcomes by enabling initiation of treatment before end organ damage has progressed. The aim of this study was to determine whether the clinical sign of phimosis with preputial fissures is predictive of type 2 diabetes in patients not previously diagnosed with diabetes. Twenty-eight patients with acquired phimosis and preputial fissures were collected prospectively. Twenty-eight controls with acquired phimosis without preputial fissures were selected. Statistically significant differences were found in body mass index, random plasma glucose, glucosuria and glycosylated haemoglobin levels, but not in age, family history of diabetes, hypertension and classical hyperglycaemic symptoms. Diabetes was confirmed in all 28 patients in the preputial fissures group, but only 2 (7.1%) patients in the non-preputial fissures group (p < 0.0001). In conclusion, phimosis with preputial fissures may be a specific sign of undiagnosed diabetes mellitus.

Peyronie's Disease: AUA Guideline.

PURPOSE: The purpose of this guideline is to provide a clinical framework for the diagnosis and treatment of Peyronie's disease. MATERIALS AND METHODS: A systematic review of the literature using the PubMed®, EMBASE® and Cochrane databases (search dates 1/1/1965 to 1/26/15) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of PD. The review yielded an evidence base of 303 articles after application of inclusion/exclusion criteria. RESULTS: The systematic review was used to create guideline statements regarding treatment of PD. When sufficient evidence existed, the body of evidence for a particular treatment was assigned a strength rating of A (high quality evidence; high certainty), B (moderate quality evidence; moderate certainty), or C (low quality evidence; low certainty). Evidence-based statements of Strong, Moderate, or Conditional Recommendation were developed based on benefits and risks/burdens to patients. Additional consensus statements related to the diagnosis of PD are provided as Clinical Principles and Expert Opinions due to insufficient published evidence. CONCLUSIONS: There is a continually expanding literature on PD; the Panel notes that this document constitutes a clinical strategy and is not intended to be interpreted rigidly. The most effective approach for a particular patient is best determined by the individual clinician and patient in the context of that patient's history, values, and goals for treatment. As the science relevant to PD evolves and improves, the strategies presented here will be amended to remain consistent with the highest standards of clinical care.

The Efficacy of Postoperative Adjuvant Chemotherapy for Patients with pT3N0M0 Upper Tract Urothelial Carcinoma.

PURPOSE: Nephroureterectomy with bladder cuff excision may not be sufficient as monotherapy for patients with pT3N0M0 upper tract urothelial carcinoma. The efficacy of postoperative adjuvant chemotherapy in this setting remains controversial. We evaluated the efficacy of adjuvant chemotherapy for patients with pT3N0M0 upper tract urothelial carcinoma in overall, cancer specific and recurrence-free survival. MATERIALS AND METHODS: We retrospectively reviewed records on 171 consecutive patients with pT3N0M0 upper tract urothelial carcinoma treated with radical nephroureterectomy between 2004 and 2014 at 2 branches of the same institution. Postoperative adjuvant chemotherapy was gemcitabine/cisplatin or cisplatin/fluorouracil/leucovorin. Overall, cancer specific and recurrence-free survival rates were estimated using the Kaplan-Meier method. The values of prognostic factors were evaluated by Cox regression analysis. RESULTS: Postoperative adjuvant chemotherapy was administered in 60 patients vs nonadjuvant therapy in 111 patients. Median followup was 35.8 months. Between the adjuvant and nonadjuvant treatment groups there were statistically significant differences in 5-year cancer specific (80.5% vs 57.6%, p = 0.010) and recurrence-free (74.4% vs 52.9%, p = 0.026) survival rates. Although there was no statistically significant difference in overall survival (71.9% vs 49.0%, p = 0.072), there was a trend of better overall survival in the patients who received postoperative chemotherapy. On multivariable analysis age (p = 0.018), tumor location (p = 0.003) and adjuvant chemotherapy (p = 0.001) were predictors of cancer specific survival. CONCLUSIONS: Adjuvant chemotherapy improves cancer specific and recurrence-free survival in patients with pT3N0M0 upper tract urothelial carcinoma after radical nephroureterectomy.

The influence of sexual orientation and sexual role on male grooming-related injuries and infections.

AIM: Pubic hair grooming is a common practice in the United States and coincides with prevalence of grooming-related injuries. Men who have sex with men (MSM) groom more frequently than men who have sex with women (MSW). We aim to characterize the influence of sexual orientation and sexual role on grooming behavior, injuries, and infections in men in the United States. METHODS: We conducted a nationally representative survey of noninstitutionalized adults aged 18-65 residing in the United States. We examined the prevalence and risk factors of injuries and infections that occur as a result of personal grooming. RESULTS: Of the 4,062 men who completed the survey, 3,176 (78.2%) report having sex with only women (MSW), 198 (4.9%) report sex with men (MSM), and 688 (16.9%) report not being sexually active. MSM are more likely to groom (42.5% vs. 29.0%, P < 0.001) and groom more around the anus, scrotum, and penile shaft compared with MSW. MSM receptive partners groom more often (50.9% vs. 26.9%, P = 0.005) and groom more for sex (85.3% vs. 51.9%, P < 0.001) compared with MSM insertive partners. MSM report more injuries to the anus (7.0% vs. 1.0%, P < 0.001), more grooming-related infections (7.0% vs. 1.0%, P < 0.001) and abscesses (8.8% vs. 2.5%, P = 0.010), as well as lifetime sexually transmitted infections (STIs) (1.65 vs. 1.45, P = 0.038) compared with MSW. More receptive partners report grooming at the time of their STI infection (52.2% vs. 14.3%, P < 0.001) compared with insertive partners. CONCLUSIONS: Sexual orientation, and in particular sexual role, may influence male grooming behavior and impact grooming-related injuries and infections. Anogenital grooming may put one at risk for an STI. Healthcare providers should be aware of different grooming practices in order to better educate safe depilatory practices (i.e., the use of electric razors for anogenital grooming) in patients of all sexual orientations.

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.
