- Vulvar and Vaginal Atrophy in Postmenopausal Women: Findings from the REVIVE (REal Women's VIews of Treatment Options for Menopausal Vaginal ChangEs) Survey. [JOURNAL ARTICLE]
- J Sex Med 2013 May 16.
INTRODUCTION:Vulvar and vaginal atrophy (VVA) is a chronic medical condition experienced by many postmenopausal women. Symptoms include dyspareunia (pain with intercourse), vaginal dryness, and irritation and may affect sexual activities, relationships, and activities of daily life.
AIM:The aim of this study is to characterize postmenopausal women's experience with and perception of VVA symptoms, interactions with healthcare professionals (HCPs), and available treatment options.
METHODS:An online survey was conducted in the United States in women from KnowledgePanel(®) , a 56,000-member probability-selected Internet panel projectable to the overall US population. Altogether, 3,046 postmenopausal women with VVA symptoms (the largest US cohort of recent surveys) responded to questions about their knowledge of VVA, impact of symptoms on their activities, communication with HCPs, and use of available treatments.
MAIN OUTCOME MEASURES:Percent is calculated as the ratio of response over total responding for each question for all and stratified participants.
RESULTS:The most common VVA symptoms were dryness (55% of participants), dyspareunia (44%), and irritation (37%). VVA symptoms affected enjoyment of sex in 59% of participants. Additionally, interference with sleep, general enjoyment of life, and temperament were reported by 24%, 23%, and 23% of participants, respectively. Few women attributed symptoms to menopause (24%) or hormonal changes (12%). Of all participants, 56% had ever discussed VVA symptoms with an HCP and 40% currently used VVA-specific topical treatments (vaginal over-the-counter [OTC] products [29%] and vaginal prescription therapies [11%]). Of those who had discussed symptoms with an HCP, 62% used OTC products. Insufficient symptom relief and inconvenience were cited as major limitations of OTC products and concerns about side effects and cancer risk limited use of topical vaginal prescription therapies.
CONCLUSIONS:VVA symptoms are common in postmenopausal women. Significant barriers to treatment include lack of knowledge about VVA, reluctance to discuss symptoms with HCPs, safety concerns, inconvenience, and inadequate symptom relief from available treatments.

- Impact of a First Treatment with Phosphodiesterase Inhibitors on Men and Partners' Quality of Sexual Life: Results of a Prospective Study in Primary Care. [JOURNAL ARTICLE]
- J Sex Med 2013 May 16.
INTRODUCTION.: Phosphodiesterase type 5 inhibitors (PDE5is) as oral treatment for erectile dysfunction (ED) facilitate the management of ED in primary care. Still, compliance is low and general practitioners (GPs) do not always feel confident with this pathology. AIM.: The aim of this paper is to evaluate the impact of a first treatment with PDE5i on the patient and his partner and the management of ED by GPs.
METHODS.:The Evaluation après traitement de la dyfonction erectile, du bien-êtré émotionnel d'un patient en fonction de la rigidité de son érection survey was a longitudinal, observational French study with prospective collection of data from the GP, the patient, and his partner at baseline and after 3 months of treatment. GPs benefited from a short educational session before starting the survey. MAIN OUTCOME MEASURES.: The main outcome measures are the Erection Hardness Score (EHS), Self-Esteem and Relationship (SEAR) questionnaire, Index of Sexual Life (ISL), and Erectile Dysfunction Inventory of Treatment Satisfaction.
RESULTS.:A total of 478 men aged 19-80 years (mean 57 years) were included in the survey by 229 GPs. Before treatment, EHS was mostly grade 1 (28%) or 2 (44%). At the end of the survey, an improvement was reported for 88% of the patients and 58% achieved maximum score EHS 4 (penis completely hard and fully rigid). Mean SEAR scores significantly increased after 3 months for self-esteem, overall and sexual relationship, and more notably with greater improvement in EHS (P < 0.001). Improvement in partners' ISL scores was significantly higher with greater improvement in EHS (P < 0.001) and in SEAR score for self-esteem. The safety profile of PDE5i was good with few adverse events, mostly headaches. More than 80% of the participating GPs considered that the survey had changed their management of ED.
CONCLUSION.: After 3 months of treatment with PDE5i, a significant improvement in self-esteem was observed in patients with ED, associated with improvement in erection.

- Efficacy of Flibanserin in Women with Hypoactive Sexual Desire Disorder: Results from the BEGONIA Trial. [JOURNAL ARTICLE]
- J Sex Med 2013 May 14.
INTRODUCTION:Hypoactive Sexual Desire Disorder (HSDD) is characterized by low sexual desire that causes marked distress or interpersonal difficulty.
AIM:The aim of this study was to assess the efficacy and safety of the 5-HT1A agonist/5-HT2A antagonist flibanserin in premenopausal women with HSDD.
METHODS:This was a randomized, placebo-controlled trial in which premenopausal women with HSDD (mean age: 36.6 years) were treated with flibanserin 100 mg once daily at bedtime (qhs) (n = 542) or placebo (n = 545) for 24 weeks.
MAIN OUTCOME MEASURES:Coprimary end points were the change from baseline to study end in Female Sexual Function Index (FSFI) desire domain score and in number of satisfying sexual events (SSE) over 28 days. Secondary end points included the change from baseline in FSFI total score, Female Sexual Distress Scale-Revised (FSDS-R) total score, and FSDS-R Item 13 score.
RESULTS:Compared with placebo, flibanserin led to increases in mean (standard deviation) SSE of 2.5 (4.6) vs. 1.5 (4.5), mean (standard error [SE]) FSFI desire domain score of 1.0 (0.1) vs. 0.7 (0.1), and mean (SE) FSFI total score of 5.3 (0.3) vs. 3.5 (0.3); and decreases in mean (SE) FSDS-R Item 13 score of -1.0 (0.1) vs. -0.7 (0.1) and mean (SE) FSDS-R total score of -9.4 (0.6) vs. -6.1 (0.6); all P ≤ 0.0001. The most frequently reported adverse events in the flibanserin group were somnolence, dizziness, and nausea, with adverse events leading to discontinuation in 9.6% of women receiving flibanserin vs. 3.7% on placebo.
CONCLUSION:In premenopausal women with HSDD, flibanserin 100 mg qhs resulted in significant improvements in the number of SSE and sexual desire (FSFI desire domain score) vs. placebo. Flibanserin was associated with significant reductions in distress associated with sexual dysfunction (FSDS-R total score) and distress associated with low sexual desire (FSDS-R Item 13) vs. placebo. There were no significant safety concerns associated with the use of flibanserin for 24 weeks. Katz M, DeRogatis LR, Ackerman R, Hedges P, Lesko L, Garcia M, and Sand M.

- The Sexual Functioning Profile of a Nonforensic Sample of Individuals Reporting Sexual Aggression Against Women. [JOURNAL ARTICLE]
- J Sex Med 2013 May 13.
INTRODUCTION:Sexual offenders are believed to present marked sexual difficulties. However, most of the studies characterizing sex offenders' sexual functioning were conducted with samples of documented/incarcerated sexual aggressors. At the present state of the knowledge there is limited information on the sexual functioning profile of individuals reporting some form of sexual violence but who were not documented/apprehended by the judicial system.
AIM:The aim of this preliminary study was to characterize a sample of community sexual aggressors (college students) according to their sexual functioning. Results were expected to add information about the relationship between sexual functioning and sexual violence, and to impact strategies aimed at preventing sexual aggression on college campus.
METHODS:One hundred sixty-one male college students participated in a cross-sectional study. Students were recruited at a Portuguese university using nonrandom methods. Among these students, 35 reported sexual aggression against women. The measures were completed individually and anonymously.
MAIN OUTCOME MEASURES:Participants completed a modified version of the International Index of Erectile Function, the Sexual Inhibition and Sexual Excitation Scales, the Sexual Self-Consciousness Scale, the Questionnaire of Cognitive Schema Activation in Sexual Context, and the Sexual-Esteem Scale.
RESULTS:Results indicated that students reporting sexual aggression against women presented significantly more erectile and orgasmic difficulties, and more sexual inhibition due to the threat of performance failure than the control peers. Additionally, students reporting sexual aggression presented more sexual embarrassment, and more schemas of undesirability and incompetence.
CONCLUSIONS:Results pointed toward a possible relationship between sexual violence as reported by college students and sexual performance anxiety. These findings are expected to impact conceptual models on sexual aggression perpetrated by nonforensic individuals. Carvalho J, Quinta-Gomes A, and Nobre PJ.

- The Global Online Sexuality Survey (GOSS): The United States of America in 2011 Chapter III-Premature Ejaculation Among English-Speaking Male Internet Users. [JOURNAL ARTICLE]
- J Sex Med 2013 May 13.
INTRODUCTION:The Global Online Sexuality Survey (GOSS) is a worldwide epidemiologic study of sexuality and sexual disorders. In 2010, the first report of GOSS came from the Middle East.
AIM:This report studies the prevalence rate of premature ejaculation (PE) in the U.S. as of 2011-2012 and evaluates risk factors for PE.
METHODS:GOSS was randomly deployed to English-speaking male web surfers in the USA via paid advertising on Facebook®, comprising 146 questions.
MAIN OUTCOME MEASURES:Prevalence of PE as per the International Society of Sexual Medicine's (ISSM) definition.
RESULTS:With a mean age of 52.38 years ± 14.5, 1,133 participants reported on sexual function. As per the ISSM definition of PE, the prevalence rate of PE in the USA as of 2011 was 6.3%. This is in contrast to 49.6% as per the Premature Ejaculation Diagnostic Tool (PEDT), 77.6% as per unfiltered subjective reports, and 14.4% as per subjective reporting on more consistent basis. 56.3% of the latter reported lifelong PE. 63.2% could be classified as having natural variable PE. Erectile dysfunction is a possible predisposing factor for acquired PE, while genital size concerns may predispose to lifelong PE. Age, irregular coitus, circumcision, and the practice of masturbation did not pose a risk for PE, among other risk factors. Oral treatment for PE was more frequently used and reported to be more effective than local anesthetics, particularly in those with lifelong PE.
CONCLUSION:Applying the ISSM definition, prevalence of PE is far less than diagnosed by other methods, 6.3% among Internet users in USA as of the year 2011. PEDT measures both lifelong and acquired PE, in addition to 35% men with premature-like ejaculatory dysfunction, making it inaccurate for isolating lifelong and acquired PE cases. Shaeer O.

- Endothelium-Independent Relaxant Effect of Rubus Coreanus Extracts in Corpus Cavernosum Smooth Muscle. [JOURNAL ARTICLE]
- J Sex Med 2013 May 13.
INTRODUCTION:Rubus coreanus is a perennial shrub native to the southern part of the Korean peninsula. Although it is known that R. coreanus has a dose-dependent relaxation effect on rabbit corpus cavernosum (CC), the exact mechanism of action by which R. coreanus work is not fully known.
AIMS:To elucidate the direct effects of unripe R. coreanus extract (RCE) on CC smooth muscle cells.
METHODS:Dried unripe R. coreanus fruits were pulverized and extracted with 95% ethanol. Isolated rabbit CC strips were mounted in an organ-bath system, and the effects of RCE were evaluated. To estimate [Ca(2+) ]i , we used a Fura-2 fluorescent technique.
MAIN OUTCOME MEASURES:The effects of unripe RCE on ion channels and the intracellular Ca(2+) concentration ([Ca(2+) ]i ) of CC.
RESULTS:RCE effectively relaxed phenylephrine (PE)-induced tone in rabbit CC, and removal of the endothelium did not completely abolish the relaxation effect of RCE. Tetraethylammonium (1 mM) did not inhibit RCE-induced relaxation in strips precontracted by PE in the organ bath. However, CaCl2 -induced constriction of CC strips, bathed in Ca(2+) -free buffer and primed with PE, was abolished by RCE. In addition, RCE decreased basal [Ca(2+) ]i in corporal smooth muscle cells. The increases of [Ca(2+) ]i evoked by 60 mM K(+) -containing solution in A7r5 cells were suppressed by RCE, and RCE relaxed KCl-induced tone in endothelium-free CC, which indicated that RCE blocked the voltage-dependent Ca(2+) channels (VDCCs). RCE decreased basal [Ca(2+) ]i and the [Arg8]-vasopressin-induced [Ca(2+) ]i increases in A7r5 cells, and RCE inhibited the contraction of endothelium-free CC induced by PE in Ca(2+) -free solution, which suggested that RCE might act as a modulator of corporal smooth muscle cell tone by inhibiting Ca(2+) release from sarcoplasmic reticulum.
CONCLUSION:RCE acts through endothelium-independent and endothelium-dependent pathways to relax CC. RCE may inhibit VDCCs and Ca(2+) release from sarcoplasmic reticulum.

- The Relationship Between Erectile Dysfunction and Open Urethroplasty: A Systematic Review and Meta-Analysis. [JOURNAL ARTICLE]
- J Sex Med 2013 May 8.
INTRODUCTION:Various urethroplasty techniques have been used to treat urethral stricture. Whether the patient erectile function is affected by this open surgery is still controversial.
AIM:The aim of this study is to determine the relationship between erectile function and open urethroplasty.
METHODS:A systematic review of the literature was performed using Medline, Embase, the Web of Science, and the Cochrane Library databases through October 2012 to identify articles published in any language that examined the effect of open urethroplasty on the risk of erectile dysfunction (ED). This meta-analysis was conducted according to the guidelines for the meta-analysis of observational studies in epidemiology.
MAIN OUTCOME MEASURES:The incidence of ED after urethroplasty.
RESULTS:This meta-analysis consisted of 23 cohort studies, which included 1,729 cases. No significant difference was noticed in patients with anterior urethral stricture before or after intervention (odds ratio [OR] = 0.86; 95% confidence interval [CI]: 0.52-1.40; P = 0.53). While statistical difference in the incidence of ED was revealed in patients before and after intervention for a posterior urethral (OR = 2.51; 95% CI: 1.82-3.45; P < 0.001), further comparisons demonstrated that most anterior urethroplasties did not have an obvious effect on patient erectile function. However, it seems that the incidence of ED was higher in the bulbar anastomosis group than in the oral graft urethroplasty group (OR = 0.32 95% CI: 0.11-0.93; P = 0.04). For the posterior urethroplasty, previous operative history did not show a strong relationship with ED. No statistically significant difference in the risk of ED was demonstrated comparing the posterior urethral reconstructive techniques included in this analysis.
CONCLUSION:The adverse effect of urethroplasty itself on erectile function is limited, as more patients recover erectile function after urethral reconstruction. For anterior urethroplasty, bulbar anastomosis might cause a slightly higher incidence of ED than other operations. For posterior urethroplasty, trauma might be the main cause of ED.

- Prevalence and Factors Associated with the Complaint of Premature Ejaculation and the Four Premature Ejaculation Syndromes: A Large Observational Study in China. [JOURNAL ARTICLE]
- J Sex Med 2013 May 7.
INTRODUCTION:Although the new classification of premature ejaculation (PE) has been proposed by Waldinger et al., there have been few studies investigating the four PE syndromes in China.
AIMS:We investigated the prevalence and factors associated with the complaint of PE and the four PE syndromes in Anhui province, China.
METHODS:Between September 2011 and September 2012, subjects were selected from five cities in Anhui province, China. They participated in this survey by completing a detailed verbal questionnaire regarding their demographic data and medical and sexual history. Men with PE complaint were diagnosed as lifelong PE (LPE), acquired PE (APE), natural variable PE (NVPE), or premature-like ejaculatory dysfunction (PLED).
MAIN OUTCOME MEASURES:PE complaint was divided into four PE syndromes. Anxiety, depression, and erectile dysfunction were independently assessed by the self-rating anxiety/depression scale and the international index of erectile function-5, respectively.
RESULTS:Of the 3,016 men evaluated, 25.80% complained of PE. The distribution of the four PE syndromes in men with PE complaint was in the order of NVPE (44.09%), PLPE (24.81%), APE (18.77%), and LPE (12.34%). Patients with PE complaint were older and more likely to smoke, had more comorbidities, and a higher body mass index (BMI) than patients without the complaint (P < 0.001 for all). Similar findings were also observed in patients with APE compared with other PE patients (depression P = 0.012, cardiovascular P = 0.003, others P < 0.001). In addition, the rates of counseling by a doctor in men with LPE and APE were higher than those in men with NVPE and PLED (P < 0.001).
CONCLUSION:The prevalence of PE complaint in male population of Anhui province, China, was 25.80%, with the highest PE syndromes being NVPE and PLPE. Patients with PE complaint or APE were older and more likely to smoke, had more comorbidities, and a higher BMI. Gao J, Zhang X, Su P, Liu J, Xia L, Yang J, Shi K, Tang D, Hao Z, Zhou J, and Liang C.
