    OBJECTIVES: To examine the prevalence, characteristics, and impact of sexual dysfunction in our primary care referral population.
    METHODS: Participants seeking treatment for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) were recruited from general urology clinics. The subjects completed the National Institutes of Health-Chronic Prostatitis Symptom Index, International Index of Erectile Function-5, and selected questions from the University of Washington Symptom Score. Additional information on demographics and medical and treatment history were also obtained. Sexual dysfunction was defined as self-reported erectile dysfunction (ED) or ejaculatory difficulty, or both.
    RESULTS: Of 296 participants with CP/CPPS, 214 (72.3%) reported sexual dysfunction. The National Institutes of Health-Chronic Prostatitis Symptom Index total score averaged 22.5 +/- 6.9 for participants with sexual dysfunction compared with 20.4 +/- 7.8 for participants who did not report sexual dysfunction (P = 0.03). Of the 214 participants with sexual dysfunction, 54 (25.0%) complained of ED only, 71 (33.4%) complained of ejaculatory difficulties only, and 89 (41.6%) complained of both ED and ejaculatory difficulties. Men reporting both ED and ejaculatory difficulty reported worse CP/CPPS symptoms (analysis of variance, P = 0.042) and worse quality of life (analysis of variance, P = 0.006) than men without sexual dysfunction.
    CONCLUSIONS: Sexual dysfunction was reported by almost three quarters of patients with CP/CPPS. Patients with CP/CPPS and sexual dysfunction experienced substantially worse symptoms, particularly worse quality of life, than other patients with CP/CPPS. Sexual dysfunction merits consideration as an important aspect of CP/CPPS and a potential outcome measure.

    INTRODUCTION: Premature ejaculation (PE) is common. However, it has been underreported and undertreated.
    AIMS: To determine the prevalence of PE and to investigate possible associated factors of PE.
    METHODS: This cross-sectional study was conducted at a primary care clinic over a 3-month period in 2008. Men aged 18-70 years attending the clinic were recruited, and they completed self-administered questionnaires that included the Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function, sociodemography, lifestyle, and medical illness. The operational definition of PE included PE and probable PE based on the PEDT.
    MAIN OUTCOME MEASURE: Prevalence of PE.
    RESULTS: A total of 207 men were recruited with a response rate of 93.2%. There were 97 (46.9%) Malay, 57 (27.5%) Chinese, and 53 (25.6%) Indian, and their mean age was 46.0 ± 12.7 years. The prevalence of PE was 40.6% (N = 82) (PE: 20.3%, probable PE: 20.3% using PEDT). A significant association was found between ethnicity and PE (Indian 49.1%, Malay 45.4%, and Chinese 24.6%; χ(2) = 8.564, d.f. = 2, P = 0.014). No significant association was found between age and PE. Multivariate analysis showed that erectile dysfunction (adjusted odds ratio [OR] 4.907, 95% confidence interval [CI] 2.271, 10.604), circumcision (adjusted OR 4.881, 95% CI 2.346, 10.153), sexual intercourse ≤5 times in 4 weeks (adjusted OR 3.733, 95% CI 1.847, 7.544), and Indian ethnicity (adjusted OR 3.323, 95% CI 1.489, 7.417) were predictors of PE.
    CONCLUSION: PE might be frequent in men attending primary care clinics. We found that erectile dysfunction, circumcision, Indian ethnicity, and frequency of sexual intercourse of ≤5 times per month were associated with PE. These associations need further confirmation.

    INTRODUCTION: Sexual problems are common in the general population. Studies have shown that most of these sexual problems are related to their social lives, medical illnesses, and psychological status. Among the sexual problems in men, premature ejaculation (PE) is one of the most frequent, yet it is the least well-understood of the sexual dysfunctions of men.
    AIM: To determine the prevalence of sexual problem particularly PE and erectile dysfunction (ED) among people living in urban areas and to investigate the characteristics associated with these sexual problems in a Malaysian population.
    MAIN OUTCOME MEASURE: The PE which is defined as an intravaginal ejaculation latency time less than 2 minutes was assessed in the ED and non-ED group.
    METHODS: The Hospital Anxiety and Depression scale is used as a measure of the psychological status [30]. The ED status was assessed using the International Index of Erectile Function questionnaire.
    RESULTS: The prevalence of self-reported sexual problems for ED and PE were 41.6% and 22.3%, respectively. In those subjects with ED, 33.5% reported to have PE. Of the total of 430 subjects, anxiety was present in 8.1%, while depression was 5.3%. The prevalence of PE accounted for 25% anxiety and 14.6% for depression respectively in the population. EDs were associated with diabetes and hypertension (OR [95% CI]: 5.33 [2.33, 10.16], 3.40 [1.76, 6.57], P < 0.05), respectively, while factors associated with PE were anxiety and depression (OR [95% CI]: 1.29 [0.68, 2.45], 1.39 [0.69, 2.78]), respectively.
    CONCLUSION: Prevalence of ED is associated with medical symptoms such as diabetes and hypertension and a rise in the prevalence of age while psychological distress such as anxiety and depression also contribute to a higher PE rate.

    BACKGROUND: The field of study addressing the relationship between FSD and male sexual dysfunction (MSD) represents a pivotal worldwide health issue as interrelationship between FSD and MSD studies are still inconclusive.

    AIM: To review the interrelationship between FSD and MSD and to conclude whether there is a definitive risk of men developing sexual dysfunction when his partner is suffering from FSD.

    METHODS: The investigation was conducted following the standard practice for conducting and reporting the findings of systematic reviews and meta-analyses comprising of 4 electronic databases, that is, Embase, PsycInfo, Cochrane Library and Ovid (Medline) from inception to December 2019. Search strategies were developed based on relevant keywords with appropriate truncation and Boolean operators' approach. The quality of studies was employed using the McMaster Critical Review Form for Quantitative Studies and were assessed by independent reviewers. The levels of evidence of the included studies were also determined.

    OUTCOMES: MSD who had been exposed to FSD.

    RESULTS: From more than 8,000 studies searched, 26 studies were finally included, and most included studies have reasonable quality. Meta-analysis found a significant sexual dysfunction in men who are partnered with women with FSD. It found a consistent correlation between FDS and sexual dysfunction in men with a significant 3-fold increase in MSD who are partnered with women with FSD (odds ratio = 3.011, 95% confidence interval: 1.856-4.885, P =

    The aim of this study was to assess the effects of treating lower urinary tract symptoms (LUTS) on the quality of sexual function in a one-year follow up. A total of 116 patients with LUTS received alpha-blocker treatment, 111 patients underwent transurethral resection of the prostate (TURP) and 70 patients with renal stones, with no or mild symptoms served as a control group. The patients were assessed at baseline, three months, six months and twelve months using the International Index of Erectile Function (IIEF-15). The surgical group exhibited some changes in the domain of IIEF-15. Patients in the medical group showed improvement in erectile function and intercourse satisfaction, while orgasmic, overall sexual satisfaction and sexual drive were relatively unchanged. In contrast, the surgical group suffered retrograde ejaculation and overall sexual dissatisfaction after undergoing TURP. TURP has been found to be associated with retrograde ejaculation intercourse and overall sexual dissatisfaction.

    The insect male accessory gland (MAG) is an internal reproductive organ responsible for the synthesis and secretion of seminal fluid components, which play a pivotal role in the male reproductive strategy. In many species of insects, the effective ejaculation of the MAG products is essential for male reproduction. For this purpose, the fruit fly Drosophila has evolved binucleation in the MAG cells, which causes high plasticity of the glandular epithelium, leading to an increase in the volume of seminal fluid that is ejaculated. However, such a binucleation strategy has only been sporadically observed in Dipteran insects, including fruit flies. Here, we report the discovery of binucleation in the MAG of the common bed bug, Cimex lectularius, which belongs to hemimetabolous Hemiptera phylogenetically distant from holometabolous Diptera. In Cimex, the cell morphology and timing of synchrony during binucleation are quite different from those of Drosophila. Additionally, in Drosophila, the position of the two nuclei in the adult stage changes as a result of the mating history or the nutrient conditions; however, it remains stable in Cimex. These differences suggest that binucleation in the Cimex MAG plays a unique role in the male reproductive system that is distinct from that of Drosophila.

    This study was conducted to evaluate the response of Bali bulls (Bos javanicus) to different semen collection methods and their effects on fresh and post-thawed semen quality. The collection methods employed were electro-ejaculation (EE), transrectal massage (RM) and RM followed by EE (RM + EE). A total of 25 untrained Bali bulls (age between 2 and 4 years old) were subjected to the different semen collection methods. Fresh semen samples from all the 25 bulls were evaluated for volume, pH, general motility, live/dead ratio and abnormality using the conventional method. For fresh and frozen samples collected by EE and RM from 10 bulls, computer-assisted semen analysis system was used for precise quantitative measurement of motility, velocity and forward progression. Accucell photometer was used to measure sperm concentration in all samples, regardless fresh and frozen. Semen samples were obtained 100% of the attempts using EE, 84% using RM and 96% using RM + EE. There were no differences among the collection methods for fresh semen quality characteristics, including motility, morphology and viability, but pH and volume were higher for EE than RM and RM + EE. Higher sperm concentration was observed in semen collected by RM than the other two methods. Different age groups (2-3 and >3-4 years old) of the bulls did not show significant differences in volume, pH, sperm concentration, percentages in motility, live/dead ratio and normal sperm morphology. The quality of semen for general and progressive motility, VAP, VSL and VCL and acrosomal integrity after thawing was higher for RM than EE. In conclusion, Bali bulls appeared to respond best to EE and the combination of RM + EE than RM, as a method of semen collection, with a shorter time of stimulation required. Differences in age of the Bali bulls did not affect the semen quality.

    Cigarette-smoking in schizophrenia and its associations with sexual functioning have been relatively under-examined. The study purpose was to determine the factors associated with sexual dysfunction among schizophrenia men with nicotine dependency and those non-smokers. A retrospective study was conducted in a local hospital in Malaysia over a two-year period from 2011 to 2012. There were 54 schizophrenia men with nicotine dependency and 57 non-smokers. Sexual functioning was assessed using the Malay version of the International Index of Erectile Function-15. Logistic regression analysis was employed. All the 111 schizophrenia men had at least one sexual dysfunction domain. For the group with nicotine dependency, Positive and Negative Syndrome Scale (PANSS)-positive was positively associated with the ability to achieve orgasm and ejaculation. However, age of schizophrenia onset was negatively associated with the confidence to attain and keep an erection. For the non-smoker group, married status and duration of schizophrenia were positively associated with the ability to attain erection and overall sex life satisfaction, respectively, while age of schizophrenia onset was negatively associated with the ability to attain erection and erectile sustainability during intercourse. Among the domains, only orgasmic dysfunction was significantly associated with PANSS-positive, i.e. higher PANSS-positive score was a protective factor for orgasmic dysfunction (odds ratio = 0.37; 95% confidence interval: 0.17, 0.80; p =.012). Schizophrenia men may apparently attempt to treat their orgasmic impairment due to effect from antipsychotics through smoking cigarettes. Sexual impairment among the non-smokers may be attributed mostly to relationship issues with their partner. © 2014 Taylor & Francis.

    Thirteen sexually mature captive male lesser Malay chevrotains (Tragulus javanicus) were each anesthetized twice with tiletamine-zolazepam for electroejaculation. Viable spermatozoa were collected from all animals. The semen was creamy, milky, pale yellowish, or watery. The mean values for ejaculate volume, sperm concentration, and percentages of sperm motility, normality and viability were 23.7 +/- 2.5 microl, 366.9 +/- 127.8 x 10(6) spermatozoa/ml, 40.0% +/- 3.1%, 71.4% +/- 1.6%, and 59.6% +/- 2.1%, respectively. Semen pH was 7-8. No adverse effects of electroejaculation were noted. These are the first reported values for semen of lesser Malay chevrotain. Electroejaculation should be usable for routine semen collection in this species.

    The effect of increasing doses of various fractions of Eurycoma longifolia Jack extracts on libido was examined in middle-aged male rats. The results showed that a high dose (800 mg/kg) of all E. longifolia Jack extracts significantly increased mount frequency (MF) (P < 0.05) over that of untreated controls, but had no effect on the frequency of intromission or ejaculation. Methanol, chloroform, water, and butanol fractions exhibited MF of 2.5 +/- 0.1, 2.6 +/- 0.3, 2.5 +/- 0.1 and 2.6 +/- 0.2, respectively, in adult, middle-aged male rats, and retired breeders versus 2.3 +/- 0.1 in untreated controls. This translated to a minor increase in MF of 8.7%, 13.0%, 8.7%, and 13.0% for these fractions, respectively, during the 20-minute observation period. The results of this study show that E. longifolia Jack extracts can increase libido in middle-aged male rats.

    Premature ejaculation (PE) is a common sexual dysfunction among the general population. PE has often been associated with a psychological state of mind. Hospital Anxiety and Depression Scale (HADS) can be used as an instrument to assess the emotional and psychological state. The present study was designed to assess the reliability and validity of the HADS in a Malaysian population. The validity and reliability were studied in subjects with and without PE. Test-retest methodology was used to assess the reliability whereas Cronbach's alpha was used to assess the internal consistency. In the control and the PE groups, the internal consistency was good and a high degree of internal consistency was observed for all 14 items. In the control group, the Cronbach's alpha values at baseline were from 0.811 to 0.834, whereas for retest, the Cronbach's alpha values were from 0.821-0.838 items. Intraclass correlation coefficient (ICC) was high for the control (0.797-0.868: baseline and 0.805-0.872: retest) and PE group (0.822-0.906: baseline and 0.785-0.887: retest). The high value of ICC and the internal consistency was due to high reliability and consistency of the items at 2-week interval. A degree of significance between the baseline and week-2 scores was observed across all items in the PE group but not in the control group. The HADS is a suitable, reliable, valid and sensitive instrument to measure the clinical change for anxiety and depression in the Malaysian population.

    Introduction: A validated diagnostic questionnaire is needed in the South-East Asia region, particularly in Malaysia to detect Premature Ejaculation (PE). The objective of this study was to determine the linguistic validity of the Malay Premature Ejaculation Diagnostic Tool (MAPET). Materials and Methods: This study was conducted in a teaching hospital. The first phase involved experts’ group discussions to develop the face, content, and factorial validity of the MAPET. The second phase measured the concurrent validity of MAPET. Results: We found that the MAPET has specificity, sensitivity, positive predictive value, and negative predictive value of 79.3%, 92%, 76.7% and 93.1%, respectively in the assessment of PE. The higher score indicates severity of PE. Conclusions: MAPET is a valid self-report instrument for the assessment of PE.

    Introduction: Both premature ejaculation(PE) and erectile dysfunction(ED) are prevalent sexual health disorders that have been inadequately investigated in Malaysia, a multiethnic and conservative nation.The objective of the study was to study the relationship between PE and ED, and other common mental health issues, i.e. anxiety and depression in Malaysian urban population.
    Methods: The diagnosis for PE was established by clinical diagnosis using DSM-5 and ISSM definition criteria for PE, whereas a diagnosis of ED was established by the International Index of Erectile Function (IIEF) questionnaire. Anxiety and depression levels were detected from the Hospital Anxiety and Depression Scale (HADS).
    Results: Based on DSM-V and ISSM clinical diagnosis for PE, the prevalence of PE was found to be 25%. Erectile dysfunction (p = 0.035, OR = 3.315, 95% CI 1.088, 10.103) and severe anxiety (p = 0.020, OR = 7.656, 95% CI 1.383, 42.396) significantly predicted presence of PE.
    Conclusion: There was a strong association between PE and ED and between PE and anxiety. Routine examination for PE in male patients should address the issue and the management of both ED and anxiety among PE patients, especially in an urban Malaysian clinical and medical care setting.

    Introduction: Premature ejaculation (PE) is an important sexual problem among men attending health clinic. Impacts of this condition towards quality of life still require further exploration. Aims of the study is to determine the proportion and determinants for PE and its impact on Quality of Life (QOL) among men attending a public health clinic in Kuantan
    Methods: A cross-sectional study involving 290 respondents was conducted at a public health clinic over the period of five months (Nov 2015-March 2016). A validated self-administrated questionnaire that consisted of sociodemographic questionnaire, clinical characteristics, premature ejaculation diagnostic tool (PEDT) and WHO quality of life (WHOQOL-BREF) were used.
    Results: The proportion of PE was 33.9% with PE 18.1% (49/271) and probable PE 15.8% (43/271). Multivariate analysis showed that level of education (p=0.002, OR 3.281/95% CI 1.183, 9.101) and hypertension (p=0.047, OR 1.788/95% CI 1.008, 3.170) were the only significant predictors for PE after controlling self-reported erectile dysfunction, pulmonary and neurological disorder. PE patients had lower median scores QOL in all four domain namely physical health, psychological, social relationship, environment (all domains with p<0.001).
    Conclusions: The proportion of men diagnosed with premature ejaculation in this study is high and possibly associated with level of education and hypertension. Men with PE had lower quality of life in domains of physical health, psychological, social relationship and environment. Hence, it is
    recommended for PE screening among male attendees to primary health clinic especially those with hypertension and moderate level of education.

    Eurycoma longifolia Jack (Fam.: Simaroubaceae), known as Tongkat Ali (TA), has been known as a symbol of virility and sexual power for men. Metabolic profiling of the aqueous extract of E. longifolia (AEEL) using UPLC-MS/MS in both positive and negative modes allowed the identification of seventeen metabolites. The identified compounds were classified into four groups: quassinoids, alkaloids, triterpenes, and biphenylneolignans. AEEL is considered safe with oral LD50 cut-off >5000 mg/kg. Oral administration of 50, 100, 200, 400, or 800 mg/kg of AEEL for 10 consecutive days to Sprague-Dawley male rats caused significant reductions in mounting, intromission, and ejaculation latencies and increased penile erection index. AEEL increased total body weight and relative weights of seminal vesicles and prostate. Total and free serum testosterone and brain cortical and hippocampal dopamine content was significantly elevated in treated groups with no significant effects on serotonin or noradrenaline content.

    Premature ejaculation (PE) is one of the commonest male sexual dysfunctions. It is characterized by ejaculation which occurs before or soon after vaginal penetration, which causes significant psychological distress to the individual, and his partner. The exact cause of PE is still unknown but several mechanisms are proposed, and these involve complex interactions of neurophysiological, psychosocial, and cognitive factors. We discuss the role of serotonin, nitric oxide, phosphodiesterase enzymes and other neurotransmitters. Treatment of PE tends to co-occur with other sexual difficulties, especially erectile dysfunction (ED). Treatment with selective serotonin reuptake inhibitors (SSRIs) and Dapoxitene are also discussed in detail. The treatment strategy requires a comprehensive holistic approach incorporating both combination of psychopharmacological agent and cognitive-behavioral therapy (CBT). The present review highlights the integration of the hypothalamic-neural and reverberating emotional circuit and discusses the etiology and treatment for patients with PE.
