The association of reproductive hormones, thyroid function, and vitamin levels with premature ejaculation: A prospective case-control study. Investig Clin Urol 2024; 65:173-179. [PMID: 38454827 PMCID: PMC10925740 DOI: 10.4111/icu.20230213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 09/20/2023] [Accepted: 11/13/2023] [Indexed: 03/09/2024] Open
Abstract
PURPOSE To investigate whether serum hormone (testosterone, prolactin, gonadotropins, and thyroid hormones) and vitamin (vitamin B12, folic acid, and vitamin D) levels are associated with premature ejaculation (PE). MATERIALS AND METHODS This prospective case-control study included 126 patients with PE (lifelong PE [LPE] in 94 and acquired PE [APE] in 32) who presented to the urology outpatient clinic between April 2016 and January 2023 and 92 healthy men as a control group. The diagnosis of PE was based on the criteria defined by the International Society for Sexual Medicine. Serum total testosterone (TT), free and bioavailable testosterone, follicle-stimulating hormone, luteinizing hormone, prolactin, thyroid-stimulating hormone, free triiodothyronine, thyroxine (fT4), vitamin B12, folic acid, and vitamin D levels were measured. RESULTS Serum TT, fT4, and vitamin D levels were significantly higher in patients with PE than in the control group (p=0.022, p=0.002, and p=0.044, respectively). However, the serum vitamin B12 level was significantly lower in the PE group (p=0.021). In the multivariate logistic regression analysis, only vitamin B12 was found to be an independent risk factor for PE, with an estimated odds ratio of 0.997 (95% confidence interval 0.994-0.999, p=0.036). CONCLUSIONS This study demonstrated that lower vitamin B12 levels are associated with the presence of PE. Therefore, we believe that it would be beneficial to consider vitamin B12 levels in the evaluation of patients with PE.

Abstract
Premature ejaculation (PE) is the most common male sexual dysfunction, with 30% of men experiencing PE worldwide. According to the generally accepted classification, there are two types of PE: lifetime PE and acquired PE. Various biological and psychological causes are known to be involved in the etiology of PE. However, due to the incomplete definition and etiopathogenesis of PE, there is no effective treatment. Although clinical and animal studies indicate that hormones play a role in controlling the ejaculation process, the precise endocrine mechanisms are unclear. In addition, little is known about the role of endocrine disorders in PE etiology. However, there is evidence that diabetes mellitus (DM), obesity, metabolic syndrome (MetS), thyroid gland disorders, pituitary gland disorders, and vitamin D deficiency affect the prevalence of PE. Moreover, it has been reported that the prevalence of PE decreases with treatment of these endocrine disorders. In this review, the relationship between PE and DM, MetS, obesity, vitamin D deficiency, and thyroid and pituitary gland disorders is summarized.

Abstract
BACKGROUND AND AIMS The prevalence of sexual dysfunctions in people with diabetes is still debated and understudied in women. This study examines the prevalence of sexual dysfunction in men and women with type 1 or type 2 diabetes (T1D or T2D) and the associations with clinical and psychological variables. METHODS Adults with diabetes (n = 756) completed an online survey including questions on sexual functioning (adapted Short Sexual Functional Scale), general emotional well-being (WHO-5), symptoms of anxiety (GAD-7) and diabetes distress (PAID-20). RESULTS One third of participants reported a sexual dysfunction. Men reported erectile dysfunction (T1D: 20%; T2D: 33%), and orgasmic dysfunction (T1D: 22%; T2D: 27%). In men, sexual dysfunction was independently associated with, older age (OR = 1.05, p = 0.022), higher waist circumference (OR = 1.04; p < 0.001) and longer duration of diabetes (OR = 1.04; p = 0.007). More men with sexual dysfunction reported diabetes distress (20% vs. 12%, p = 0.026). Women reported decreased desire (T1D: 22%; T2D: 15%) and decreased arousal (T1D: 9%; T2D: 11%). More women with sexual dysfunction reported diabetes distress (36% vs. 21%, p = 0.003), impaired emotional well-being (36% vs. 25%, p = 0.036) and anxiety symptoms (20% vs. 11%, p = 0.026). CONCLUSION Sexual dysfunctions are common in both men and women with diabetes. In men, sexual dysfunctions were associated with clinical factors. More women with sexual dysfunction reported low emotional well-being and anxiety symptoms compared to women without sexual dysfunction. For both men and women, sexual dysfunctions were associated with diabetes distress.

Abstract
The aim of this study was to investigate the relationship between metabolic syndrome (MetS) and acquired premature ejaculation (PE). A total of 100 patients with acquired PE and 100 control cases were enrolled in the study. After obtaining a detailed medical history, anthropometric (weight, height and waist circumference) and blood pressure measurements were performed. Ejaculation and erection functions were evaluated by Premature Ejaculation Diagnostic Tool (PEDT) and International Index of Erectile Function-5 (IIEF-5), respectively. Self-estimated intravaginal ejaculatory latency time (IELT) of the participants was recorded. Fasting blood samples were taken for biochemical and hormonal work-up. The median PEDT scores were 16 (9-22) and 4.5 (2-8) in acquired PE and control groups, respectively (P<0.001). The mean estimated IELT values in PE patients and controls were 36.1±46.5 versus 488.2±313.8 s (P<0.001). MetS was diagnosed in 51 patients (51%) in the PE group and 24 (24%) participants in the control group (P<0.001). A significant negative correlation was observed between the components of MetS and estimated IELT, except for diastolic blood pressure. Moreover, there was a significant positive correlation between the all components of MetS and total PEDT score, except for fasting blood glucose and high-density lipoprotein cholesterol (HDL) levels. Logistic regression analysis revealed that, except blood pressure and HDL levels, MetS components were significant risk factors for PE after adjusting for age and total testosterone. In conclusion, MetS is associated with acquired PE.

Abstract
Hypothyroidism is a condition in which the serum levels of thyroid hormones are below that necessary to carry out physiological functions in the body. Hypothyroidism is related to obesity as an increase in body weight gain is seen in hypothyroid patients. Moreover, an inverse correlation between free thyroxine values and body mass index has been reported. Leptin, a polypeptide hormone produced by adipocytes, was originally thought to be an antiobesity hormone due its anorexic effects on hypothalamic appetite regulation. However, nowadays it is known that leptin conveys information about the nutritional status to the brain being considered a crucial endocrine factor for regulating several physiological processes including reproduction. Since the identification of thyroid hormone and leptin receptors on the testes, these hormones are being recognized as having important roles in male reproductive functions. A clear link exists among thyroid hormones, leptin and reproduction. Both hormones can negatively affect spermatogenesis and consequently may cause male infertility. The World Health Organization (WHO) estimates the overall prevalence of primary infertility ranging from 8 to 15%. The fact that 30% of couples' inability to conceive is related to a male factor and that the longer hypothyroidism persisted, the greater the damage to the testes, strongly suggest that more studies attempting to clarify both hormones actions directly in the testes need to be conducted specially in cases of congenital hypothyroidism. Therefore, the goal of this review is to highlight the relationship of such hormones in the reproductive system.

Abstract
CONTEXT Sexual dysfunction (SD) among diabetic women is an important disorder. It has many negative effects on general health. AIMS This study aimed to compare SD status between diabetic and non-diabetic women. SETTINGS AND DESIGN This study was conducted on 200 women, half of them diabetic and the others as non-diabetic in Tohid Hospital (Sanandaj, Iran). MATERIALS AND METHODS The non-diabetic group was matched for age (±5 years) and education. Data were collected using an interview-based questionnaire containing demographic characteristics and female sexual function index (FSFI). STATISTICAL ANALYSIS USED Univariate and multivariate analyses were performed to assess and interpret the results. RESULTS Analyses of the data showed that low educational levels, longer duration of diabetes and poor controlled diabetes were associated with the lower FSFI scores. In both groups the prevalence of SDs for all FSFI domains was high. Furthermore, multivariate analysis showed that these three variables were associated with lower FSFI scores. CONCLUSIONS Study confirms that Kurdish Iranian diabetic women are at an increased risk of SD. Low educational level, longer duration of diabetes, and poor controlled diabetes were associated with a lower FSFI score.

Abstract
BACKGROUND Erectile dysfunction (ED), defined as the inability to achieve or maintain an erection sufficient for satisfactory sexual performance, is a common condition. The psychological, hormonal, neurogenic and arterial pathologies, medications, chronic diseases have been reported in the etiology of the ED. This paper aims to study sexual dysfunction in the male patients with migraine and Tension type headache (TTH). METHODS 30 migraine cases (Group M), 31 TTH cases (Group T) and 30 control cases (Group C) were included in the study. Patients were evaluated with medical history, physical examination, body mass index (BMI), Beck Depression Inventory, biochemical analysis and hormone profiles. ED was evaluated via International Index of Erectile Function Scale (IIEF). In statistical analysis, variant analysis, post-hoc tukey test, Pearson correlation test, t-test, and fisher's exact chi-square test were used. RESULTS The patients' mean age was 34.96+/-1.30, 35.54+/-1.52 and 32.26+/-1.38 for group M,T and C, respectively. There was no significant difference between the groups in terms of testosterone levels. Mean IIEF scores was 19.83+/-2.2, 20.39+/-1.35 and 27.83+/-0.34 in groups M,T,C. When M and T groups were compared with group C, there were significant differences, and there was no statistical difference when T and M groups were compared to each other. Beck Depression Scores were not significantly different in groups M, T and C. CONCLUSION In this study, it was shown that, migraine and TTH affects the sexual functions negatively in male patients. Chronic diseases may cause sexual disorders in patients because of despair, guilt, and fear of death or pain. Our results suggest that, along with the effect of chronic disease and pain, there must be other complicated factors exist causing the development of SD in patients with migraine and TTH.

Abstract
The male refractory period (MRP) continues to be a topic of discussion and debate within the field of sexual medicine. To date explanations rely on central descending (efferent) influences involving specific neurotransmitter systems. Herein we explore the issue of the male refractory period, identifying problems with current explanations, specifying the parameters of an adequate model, and suggesting possible mechanisms mediating this phenomenon. We review the literature regarding existing explanations for the MRP and look to other systems of physiological regulation that might provide a model for the conceptualization of the MRP. Our approach differs from traditional explanations in that it emphasizes the possible roles of various peripheral, rather than central, feedback (afferent) systems that affect peripheral autonomic functioning and response. Yet our approach is consistent with other peripheral regulatory feedback systems controlling autonomic response related to such processes as heart rate, respiration, and gut motility. Although direct empirical research supporting our approach is lacking, sufficient evidence exists to support the idea that such processes are not only possible but likely with respect to the male refractory period. We suggest several lines of research that might provide empirical support for this approach.

Abstract
Hormones regulate all aspects of male reproduction, from sperm production to sexual drive. Although emerging evidence from animal models and small clinical studies in humans clearly point to a role for several hormones in controlling the ejaculatory process, the exact endocrine mechanisms are unclear. Evidence shows that oxytocin is actively involved in regulating orgasm and ejaculation via peripheral, central and spinal mechanisms. Associations between delayed and premature ejaculation with hypothyroidism and hyperthyroidism, respectively, have also been extensively documented. Some models suggest that glucocorticoids are involved in the regulation of the ejaculatory reflex, but corresponding data from human studies are scant. Oestrogens regulate epididymal motility, whereas testosterone can affect the central and peripheral aspects of the ejaculatory process. Overall, the data of the endocrine system in regulating the ejaculatory reflex suggest that widely available endocrine therapies might be effective in treating sexual disorders in these men. Indeed, substantial evidence has documented that treatments of thyroid diseases are able to improve some ejaculatory difficulties.

Abstract
Objective To review local published data on the diagnosis and treatment of erectile dysfunction (ED) in Arab countries. Methods MEDLINE was searched for English-language articles published from 2000 to 2011, using the search terms ‘Arab countries’, ‘sexual dysfunction’, ‘diagnosis’ and ‘treatment’. Results In all, 86 articles were found to be relevant to this review; only a few had a high level of evidence and the remaining studies used an uncontrolled design. Several local studies were consistent with previous reports showing that a customised diagnostic pathway, with full consideration of the patient’s goals, is adopted by most clinicians to treat ED. For an effective treatment, the evaluation methods should answer important questions about the aetiology and severity of ED, as well as the patient’s and partner’s goals and expectations. As ED is known to be associated with many common medical comorbidities and medications, careful questioning can yield information about peripheral vascular disease, coronary artery disease, diabetes, hypertension, dyslipidaemia, and tobacco and alcohol use. The presence of psychological, neurological or chronic debilitating diseases can direct further evaluation. Conclusion The methods used for the diagnosis and treatment of ED need more investigation, especially in Arab countries. Only a few studies addressed the results of different methods of investigating and treating ED among Arab men.

Abstract
INTRODUCTION Besides hypogonadism, other endocrine disorders have been associated with male sexual dysfunction (MSD). AIM To review the role of the pituitary hormone prolactin (PRL), growth hormone (GH), thyroid hormones, and adrenal androgens in MSD. METHODS A systematic search of published evidence was performed using Medline (1969 to September 2011). Oxford Centre for Evidence-Based Medicine-Levels of Evidence (March 2009) was applied when possible. MAIN OUTCOME MEASURES The most important evidence regarding the role played by PRL, GH, thyroid, and adrenal hormone was reviewed and discussed. RESULTS Only severe hyperprolactinemia (>35 ng/mL or 735 mU/L), often related to a pituitary tumor, has a negative impact on sexual function, impairing sexual desire, testosterone production, and, through the latter, erectile function due to a dual effect: mass effect and PRL-induced suppression on gonadotropin secretion. The latter is PRL-level dependent. Emerging evidence indicates that hyperthyroidism is associated with an increased risk of premature ejaculation and might also be associated with erectile dysfunction (ED), whereas hypothyroidism mainly affects sexual desire and impairs the ejaculatory reflex. However, the real incidence of thyroid dysfunction in subjects with sexual problems needs to be evaluated. Prevalence of ED and decreased libido increase in acromegalic patients; however, it is still a matter of debate whether GH excess (acromegaly) may create effects due to a direct overproduction of GH/insulin-like growth factor 1 or because of the pituitary mass effects on gonadotropic cells, resulting in hypogonadism. Finally, although dehydroepiandrosterone (DHEA) and its sulfate have been implicated in a broad range of biological derangements, controlled trials have shown that DHEA administration is not useful for improving male sexual function. CONCLUSIONS While the association between hyperprolactinemia and hypoactive sexual desire is well defined, more studies are needed to completely understand the role of other hormones in regulating male sexual functioning.

Abstract
INTRODUCTION Premature ejaculation (PE) is a frequently encountered sexual dysfunction in men. It significantly impairs quality of life of the affected male and his partner. The aim of this study is to investigate the role of hormonal factors in patients with PE. PATIENTS AND METHODS 107 male patients aged between 26 and 64 years (mean 45.1 ± 10.36) who consulted our outpatient clinics with complaints of PE and 94 healthy males (48.1 ± 11.81 years) as a control group were included in the study. RESULTS When mean serum hormone concentrations of both groups were compared, levels of prolactin and free T4 were found to be significantly higher in the PE group relative to the control group (p < 0.05). At least one of the hormonal parameters was abnormal in 36 cases (33.6%) with PE, compared to only 22 (23.4%) of the controls. The number of hyperprolactinemic cases was found to be significantly increased in the PE group (p < 0.05). CONCLUSION We feel that during the evaluation of this problem, which affects great numbers of men and their partners throughout the world, consideration of potential effects of hormonal factors might be beneficial.

Abstract
PURPOSE OF REVIEW To review physiology of prolactin (PRL), cause and managment of hyperprolactinemia, and discuss evolving diverse roles of PRL in men's health. RECENT FINDINGS Hyperprolactinemia can be physiologically found after sexual activities, exercise, lactation, during pregnancy, and after stressful venipuncture. Elevated PRL can be caused by medications use, renal failure, hypothyroidism, and by prolactinoma - PRL secreting tumors. Symptomatic hyperprolactinemia and prolactinomas should be treated to lower PRL levels, decrease tumor size, and restore gonadal function. Three modes of treatment are typically utilized: pharmacological, radiosurgery with gamma radiation, and external beam radiation. Pharmacological treatment of prolactinomas is mainly based on dopamine agonists. The most frequently used dopamine agonists are bromocriptine and cabergoline. Cabergoline becoming the preferred drug in the treatment of prolactinomas because of higher response rate and less side-effects. Bromocriptine has been recently approved to improve glycemic control in diabetes mellitus. SUMMARY PRL plays a diverse role in men's reproduction and health. Detecting and treating elevated PRL may not only improve infertility and hypogonadism but also have a positive effect on the metabolic profile of patient and control of glycemic control and metabolic profile - an important advantage considering dramatic and worldwide increase in obesity and diabetes.

Abstract
INTRODUCTION Thyroid hormones affect male and female sexual functions, but data in hypo- and hyperthyroid women are scanty. AIM To investigate sexual function in hypo- and hyperthyroid women before and immediately after restoration of euthyroidism and in women with euthyroid Hashimoto's thyroiditis (HT). PATIENTS AND CONTROLS Fifty-six women with thyroid diseases (age 19-50 yr; 22 with hyperthyroidism, 17 with hypothyroidism, and 17 with euthyroid HT) and 30 age-matched healthy women. MAIN OUTCOME MEASURES Hypoactive sexual desire, disorders of sexual arousal, vaginal lubrication, orgasm, satisfaction, and sexual pain (SPD) were assessed by Female Sexual Function Index. Serum TSH, free T4 (FT4) and thyroid autoantibodies (anti-thyroglobulin, anti-thyroperoxidase, and TSH-receptor antibodies) were assessed at the diagnosis; FT4 and TSH were repeated after treatment to confirm normalization of thyroid function. RESULTS All sexual domains scores were significantly reduced (p ranging <0.0001-<0.05) in both hypo- and hyperthyroid women. Correction of hypothyroidism was associated to normalization of desire, satisfaction, and pain, while arousal and orgasm remained unchanged. In hyperthyroid women therapy normalized sexual desire, arousal/lubrication, satisfaction, and pain, while orgasm remained significantly impaired. Interestingly, euthyroid HT women displayed a significant decrease in sexual desire (p<0.0005), with no changes in the other sexual domains. CONCLUSIONS Both hypo- and hyperthyroidism markedly impair female sexual function. A rapid improvement is observed with the restoration of euthyroidism, although a longer period of time may be needed for full normalization. Preliminary data suggest that thyroid autoimmunity may selectively impair sexual desire, independently from thyroid function.

Abstract
In this review we identify whether problems encountered in urology, such as erectile dysfunction, have a bearing on general health, in particular cardiovascular health. Testosterone, traditionally regarded as the hormone subserving male reproductive and sexual functioning, appears to have a much wider role. Recent findings show that testosterone is involved in the metabolic control of glucose and lipids, of strength of bone and muscle, and psychological aspects such as mood and energy. Serum testosterone levels decline with ageing, free testosterone levels more so than total testosterone. At least 10 publications have shown that low testosterone levels are associated with an increased risk of death. The metabolic syndrome is a clustering of risk factors predisposing to diabetes mellitus type 2, atherosclerosis, and cardiovascular morbidity and mortality. There is a direct correlation between plasma testosterone and insulin sensitivity, and low testosterone levels are associated with an increased risk of type 2 diabetes mellitus, dramatically illustrated by androgen deprivation in men with prostate carcinoma. Lower total testosterone and sex hormone-binding globulin levels predict a higher incidence of the metabolic syndrome. Administration of testosterone to hypogonadal men reverses part of the unfavourable risk profile for the development of diabetes and atherosclerosis, thus also improving risk factors for erectile dysfunction. We conclude that urologists diagnosing and treating erectile problems are in a unique position to include general aspects of men's health in their work, and thus contribute to general health and to cardiovascular health in particular.

Abstract
INTRODUCTION The physiological role of prolactin (PRL) in male sexual behavior is poorly understood. Conversely, the association between PRL pathological elevation in both reproductive and sexual behavior is well defined. AIM The aim of the present study is to assess the correlates of normal PRL (PRL < 735 mU/L or 35 ng/mL), in male subjects consulting for sexual dysfunction. METHODS A consecutive series of 2,531 (mean age 52.0 +/- 12.9 years) subjects was investigated. Patients were interviewed using the structured interview on erectile dysfunction (SIEDY), a 13-item tool for the assessment of erectile dysfunction (ED)-related morbidities. Middlesex Hospital Questionnaire was used for the evaluation of psychological symptoms. MAIN OUTCOME MEASURES Several hormonal (testosterone, thyroid stimulation hormone, and PRL) and biochemical parameters (glycemia and lipid profile) were studied, along with penile Doppler ultrasound (PDU) and SIEDY items. RESULTS After adjustment for confounders anxiety symptoms decreased across PRL quartiles (I: <113 mU/L or 5 ng/mL; II: 113-156 mU/L or 5.1-7 ng/mL; III: 157-229 mU/L or 7.1-11 ng/mL; IV: 229-734 mU/L or 11.1-34.9 ng/mL). Patients in the lowest PRL quartile showed a higher risk of metabolic syndrome (MetS; odds ratio [OR] = 1.74 [1.01-2.99], P < 0.05), arteriogenic ED (peak systolic velocity at PDU < 35 cm/sec; OR = 1.43 [1.01-2.03], P < 0.05), and premature ejaculation (PE; OR = 1.38 [1.02-1.85]; P < 0.05). Conversely, comparing subjects with PRL-secreting pituitary adenomas (N = 13) with matched controls, no significant difference was observed, except for a higher prevalence of hypoactive sexual desire in hyperprolactinemia. CONCLUSIONS Our findings demonstrate that, in subjects consulting for sexual dysfunction, PRL in the lowest quartile levels are associated with MetS and arteriogenic ED, as well as with PE and anxiety symptoms. Further studies are advisable in order to confirm our preliminary results in different populations.

Abstract
Our objective was to assess the pattern of type-2 diabetes-associated androgen alteration in patients with erectile dysfunction (ED). A total of 127 diabetic male patients with ED were enrolled in this study. Erectile function was assessed using the International Index of Erectile Function (IIEF). At the time of assessment, patients were also interviewed and assessed for socio-demographic and medical history that includes duration and severity of diabetes mellitus (DM). Patients underwent routine laboratory investigations, in addition to total testosterone (T), dehydroepiandrosterone sulphate (DHEA-S) and insulin assessment. The mean age +/- SD was 53.8 +/- 9.3 years. Of patients 25.2% (n = 32/127), 6.3% (n = 8/127) and 31.5% (n = 40/127) had low total T, low DHEA-S and hyperinsulinaemia respectively. There were significant association between the increase in age and body mass index and the presence of low T level. Of the patients 37.5% (n = 12/32) with low T level had glycosylated haemoglobin (HbA1c) >7% while, 22.1% (n = 21/95) of the patients with normal T level had HbA1c >7% (p < 0.05). There were significant associations between the number of patients with low level of total T or DHEA-S and poor control of DM. Patients with low T level were two times more likely (56.3%, n = 18/32) to have severe ED than patients with normal T level (27.4%, n = 26/95) (p < 0.01). There were significant differences between the mean levels of total T or DHEA-S and poor control of DM. No significant associations were detected between hyperinsulinaemia and the level of fasting blood sugar, duration of DM, metabolic control of DM or ED severity. Patients with low T level were three times as likely to have hyperinsulinaemia as those patients with normal T level (p < 0.05). The current study clearly demonstrated that there were significant associations between low level of total T or DHEA-S and poor control of DM.

Abstract
OBJECTIVES To assess the effect of premature ejaculation (PE) and low desire on the severity of erectile dysfunction (ED) at presentation. METHODS A total of 1680 male patients with ED with and without PE or low desire were enrolled in this study. The patients were assessed for ED using the International Index for Erectile Function. All patients were also screened for PE and low desire. Specifically, we compared the severity of ED (mild, moderate, and severe) and the mean score of the EF domain, question 3 (achieving erection), and question 4 (maintaining an erection) in patients with and without PE and/or low desire. RESULTS The mean age +/- SD for the 1680 male patients with ED was 56.8 +/- 6.9 years. No significant differences were detected between patients with or without PE or low desire in concomitance with ED regarding age, smoking, obesity, or medical comorbidities. Patients with PE and low desire were more likely to report severe than mild ED; 52.4% of patients with severe ED had PE compared with 29.5% of patients with mild ED. The patients with severe ED were more than two times as likely to report low desire as patients with mild ED. Significant associations were found between a decreased mean score for the EF domain, question 3, and question 4 and the presence of PE and/or low desire. CONCLUSIONS The results of our study have shown that PE and low desire, singly or in combination, are significantly associated with severe rather than mild ED at presentation.

Abstract
INTRODUCTION There have been limited multiregional studies in Asia examining the parameters of men's general and sexual health and quality of life in the general population vs. those in clinical cohorts of patients with erectile dysfunction (ED). AIMS The aims of the Asian Men's Attitudes to Life Events and Sexuality (Asian MALES) study were to investigate the prevalence of ED, associated health conditions, and ED treatment-seeking patterns in the general male population in five regions of Asia (China, Japan, Korea, Malaysia, and Taiwan). MAIN OUTCOME MEASURE Standardized questionnaire previously used in a similar multiregional study and modified to ensure culturally appropriate content for Asia. METHODS Phase I of the study involved 10,934 adult men, aged 20-75 years, who were interviewed using the standardized questionnaire. Phase II of the study involved men with self-reported ED recruited from Phase I and via physician referral, invitations in general practitioner offices, and street interception (total Phase II sample, N = 1,209). RESULTS The overall prevalence of self-reported ED in the Phase I study population was 6.4%. ED prevalence varied by region and significantly increased with age (P < 0.01). Men with ED reported significantly greater rates of comorbid illness (P < 0.0001) and a reduced quality of life (P = 0.0001), compared with men without ED. Phase II of the study revealed that fewer than half of men with self-reported ED had sought treatment for their problem. Men were more likely to seek help for erection difficulties from Western doctors than from traditional medicine practitioners (P = 0.0001). A man's partner/spouse was the most common influencer of treatment seeking in all regions except Malaysia. CONCLUSION The findings confirm those of existing research on ED in both Asian and non-Asian males: ED is a prevalent condition; the prevalence of ED increases with age and is strongly associated with comorbid conditions; and the majority of men have never sought treatment for their condition. This study highlights a substantial need for the evaluation and treatment of ED in Asian men.

Abstract
INTRODUCTION The physiological role of prolactin (PRL) in male sexual function has not been completely clarified. AIM The aim of this study is the assessment of clinical features and of conditions associated with hyperprolactinemia in male patients consulting for sexual dysfunction. METHODS A consecutive series of 2,146 (mean age 52.2 +/- 12.8 years) male patients with sexual dysfunction was studied. MAIN OUTCOME MEASURES Several hormonal and biochemical parameters were studied along with validated structured interviews (ANDROTEST and the Structured Interview on Erectile Dysfunction [SIEDY]). Mild hyperprolactinemia (MHPRL; PRL levels of 420-735 mU/L or 20-35 ng/mL) and severe hyperprolactinemia (SHPRL, PRL levels >735 mU/L, 35 ng/mL) were considered. RESULTS MHPRL and SHPRL were found in 69 (3.3%) and in 32 (1.5%) patients, respectively. Mean age and the prevalence of gynecomastia were similar in the two groups and in subjects with normal prolactin values. MHPRL was not confirmed in almost one-half of the patients after repetitive venous sampling. Hyperprolactinemia was associated with the current use of antidepressants, antipsychotic drugs, and benzamides. SHPRL was also associated with hypoactive sexual desire (HSD), elevated thyrotropin (TSH), and hypogonadism. The association between HSD and SHPRL was confirmed after adjustment for testosterone and TSH levels, and use of psychotropic drugs (hazard ratio [HR] = 8.60[3.85-19.23]; P < 0.0001). In a 6-month follow-up of patients with SHPRL, testosterone levels and sexual desire were significantly improved by the treatment. CONCLUSIONS Our data indicate that SHPRL, but not MHPRL, is a relevant determinant of HSD. Gynecomastia does not help in recognizing hyperprolactinemic subjects, while the use of psychotropic medications and HSD are possible markers of disease. In the case of MHPRL, repetitive venous sampling is strongly encouraged.

Abstract
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.

Abstract
INTRODUCTION Since the advent of Highly Active Anti-Retroviral Therapy (HAART), men with HIV experience good quality of life and expect to have normal sexual function. However, it appears that men infected with HIV commonly complain of sexual problems. There is evidence that men on HAART develop low sexual desire that is associated with raised estradiol levels. It has been postulated that abnormal metabolism seen in this group of men increases the aromatization of testosterone to estradiol. We hypothesized that letrozole, an aromatase inhibitor that inhibits the conversion of testosterone to estradiol, would be beneficial in these men. AIM The aim of this study was to compare the effects of testosterone vs. an aromatase inhibitor, letrazole, in HIV-infected men with raised estradiol and low sexual desire. METHODS Thirteen men who have sex with men on HAART with low sexual desire as well as raised estradiol levels (>120 pmol/L) were randomly allocated to receive either parenteral testosterone (Sustanon 250 intramuscular injection) (N = 6) or letrozole 2.5 mg orally daily (N = 7) for 6 weeks. MAIN OUTCOME MEASURES Sex steroid hormone assays, sex hormone-binding globulin, virological, hematological, and biochemical parameters were measured before and after treatment. Each subject was given the Spector Sexual Desire Inventory and the Depression/Anxiety Stress Scale before and immediately after treatment. Subjects were also asked to estimate the number of actual sexual acts before and after treatment. Results. Inventory data showed a rise in dyadic desire in both treatment arms. Mean actual sexual acts rose from 0.33 to 1.5 in the testosterone group and from 0.43 to 1.29 for the letrozole group. Luteinizing hormone increased in seven of seven men on letrozole. Serum testosterone increased in seven of seven men on letrozole. There were no adverse events from either medication. CONCLUSION Letrozole may be useful in the management of men on HAART who have low sexual desire.

Abstract
PURPOSE We assessed the pattern of age related testosterone depletion in patients with erectile dysfunction. MATERIALS AND METHODS A total of 305 patients with erectile dysfunction who had a normal testosterone level at baseline visit and who completed the study were candidates for analysis. Erectile function was assessed using the International Index of Erectile Function. Patients underwent routine laboratory investigations plus total testosterone and prolactin assessment at the baseline visit and on a yearly basis for 4 years. RESULTS The mean age +/- SD was significantly higher in 210 patients with decreased testosterone (55.3 +/- 7.3 years) than in 95 patients with steady testosterone (remaining within the normal range) (50.8 +/- 10.2 years). There was a significant decrease in yearly mean testosterone level throughout the study in all the age groups (determined by decades) older than 30 years. Of the study population 68.9% had decreases in testosterone levels throughout the 4 years of visits. Hypogonadism (testosterone lower than normal range) developed in 7.6% of the study population. There was a significant decrease in mean testosterone at any visit in comparison to previous visits. There were significant associations between decreased levels of testosterone and increased severity of erectile dysfunction at baseline visit, longer duration and poor metabolic control of diabetes, ischemic heart disease, hyperprolactinemia and low desire. CONCLUSIONS This study clearly demonstrated a decrease in testosterone level throughout the 4-year followup in patients with erectile dysfunction. Patients with decreasing testosterone were older than patients with a steady testosterone level.
