Luberti FR, Carré JM. Testosterone's role in modulating human behaviors relevant to mating and parenting. Front Neuroendocrinol 2024; 72:101112. [PMID: 37972861 DOI: 10.1016/j.yfrne.2023.101112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 11/19/2023]
Abstract
Testosterone (T) is linked to human mating and parenting. Here, we comprehensively reviewed evidence on whether, in men and women, (1) basal T levels are related to mating and parenting behaviors, (2) T responds to reproduction-relevant cues, (3) acute changes in T map onto subsequent mating and parenting behaviors, and (4) single-dose exogenous T administration causally affects mating and parenting behaviors. We examined whether the available evidence supports trade-off interpretations of T's adaptive function whereby high T levels correspond to greater mating/reproductive effort and competition and low T levels to greater parenting effort and nurturance. We found mixed support for trade-off hypotheses, suggesting that T's function in modulating human mating and parenting might be more nuanced and highly dependent on context and individual trait differences. Results were largely similar for men and women, although studies with women were scarcer than those with men for most behaviors we reviewed.

The pathophysiology of Post SSRI Sexual Dysfunction - Lessons from a case study. Biomed Pharmacother 2023; 161:114166. [PMID: 36898260 DOI: 10.1016/j.biopha.2022.114166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 12/19/2022] [Accepted: 12/28/2022] [Indexed: 03/12/2023] Open
Abstract
BACKGROUND Although Post-SSRI Sexual Dysfunction (PSSD) has finally been recognized by the European Medicines Agency as a medical condition that can outlast discontinuation of SSRI and SNRI antidepressants, this condition is still largely unknown by patients, doctors, and researchers, and hence, poorly understood, underdiagnosed, and undertreated. OBJECTIVE Becoming familiar with the symptomatology of PSSD and understanding the underlying mechanisms and treatment options. METHOD We applied a design thinking approach to innovation to 1) provide insights into the medical condition as well as the personal needs and pains of a targeted patient; and 2) generate ideas for new solutions from the perspective of this particular patient. These insights and ideas informed a literature search on the potential pathophysiological mechanisms that could underlie the patient's symptoms. RESULTS The 55-year-old male patient developed symptoms of low libido, delayed ejaculation, erectile dysfunction, 'brain zaps', overactive bladder and urinary inconsistency after discontinuation of the SNRI venlafaxine. In many of these symptoms a dysregulation in serotonergic activity has been implicated, with an important role of 5-HT1A receptor downregulation and possible downstream effects on neurosteroid and oxytocin systems. CONCLUSIONS The clinical presentation and development of symptoms are suggestive of PSSD but need further clinical elaboration. Further knowledge of post-treatment changes in serotonergic - and possibly noradrenergic - mechanisms is required to improve our understanding of the clinical complaints and to inform appropriate treatment regimes.

Abstract
OBJECTIVES Opioid analgesics are the main stay for cancer pain management; however, long-term opioid treatment (L-TOT) may suppress the endocrine system. This systemic review aimed at investigating effects of L-TOT on the endocrine system in patients with cancer-related pain. METHODS A search on MEDLINE, EMBASE and Web of Science databases was performed. Inclusion criteria were clinical studies investigating endocrine measures in adult patients with cancer-related pain in L-TOT (≥4 weeks). Outcomes and quality of evidence were assessed. RESULTS A total of 252 abstracts were identified; out of which 247 were excluded and five cross-sectional studies were included and analyzed. L-TOT was associated with lower serum concentration levels of total- and free testosterone in males, follicular stimulating hormone in females, and luteinizing hormone in both sexes. Moreover, higher morphine equivalent daily doses (MEDDs) were correlated with higher levels of cortisol and lower levels of LH in both sexes, and lower levels of total- and free testosterone in males. Sexual dysfunction was associated with low sex hormone levels. Level of evidence was low/very low. CONCLUSIONS The studies identified demonstrated that patients with cancer-related pain in L-TOT may have gonadal hypofunction causing sexual dysfunction, which may be correlated with opioid dose level. In addition, high serum concentrations of cortisol were positively correlated with high opioid dose levels. However, the evidence was weak and further research is necessary.

Abstract
Background: The aim of this study was to analyze the relationship between the prevalence of erectile dysfunction in men as diagnosed by the International Index of Erectile Function (IIEF) questionnaire and the respective levels of sex hormones and biochemical parameters, as well as indices of visceral fat accumulation and activity. Material and Methods: The study comprised 148 male (60–75 years) patients from primary care outpatient clinics in the city of Szczecin (Poland). The men were asked to complete a shortened survey questionnaire with sociodemographic data, as well as a shortened version of the IIEF (five items). Venous blood samples were collected. Total testosterone (TT), estradiol (E2), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), total cholesterol (ChT), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), fasting plasma glucose (FPG) and albumin were determined. Lipid accumulation product (LAP) and visceral adiposity index (VAI) were calculated. Results: A correlation was found in the analysis of LAP index values (OR = 1.017; p = 0.050). The analysis of hormone concentrations showed a correlation between the diagnosed trait and the value of TT (OR = 1.216; p = 0.046) and SHBG (OR = 1.020; p = 0.007). Conclusions: VAI and LAP have been shown to be good indicators for assessing erectile dysfunction in men over 60 years of age.

Abstract
Erectile dysfunction (ED) is one of the most common sexual dysfunctions in men. The prevalence of ED has been increasing in recent years, which has critically affected male reproductive health and quality of life. According to various guidelines, phosphodiesterase-5 inhibitors are the most commonly recommended drugs for treating ED. However, many patients turn to alternative therapies because of adverse reactions, such as headache, and the poor efficacy of these drugs. Acupuncture is a long-established treatment in traditional Chinese medicine (TCM) and has been approved by the World Health Organization for improving penile erection as well as other discomforts in patients. However, previous systematic reviews have not discussed the characteristics and the related mechanisms of acupuncture treatment. Therefore, this study focuses on summarizing the characteristics and advantages of TCM in acupuncture treatment for ED based on relevant literature and on predicting and analyzing the related mechanisms.

Abstract
Differences in the content of sexual fantasies across gender have been widely documented, while less attention was given to the role of sexual orientation. Previous studies focused on differences in the prevalence of broad themes consisting of sets of contents. The current study aimed to increase the knowledge about sexual fantasies in heterosexual, homosexual, and bisexual men and women. A descriptive approach that allows visualizing the patterns of fantasies reported by different groups using Multiple Correspondence Analysis (MCA) is presented. A sample of 3136 of young adults, 1754 women (Mage = 22.50, SD = 1.72, range 18–25) and 1382 men (Mage = 22.50, SD = 1.70, range 18–25), completed an online questionnaire assessing the presence of 29 different sexual fantasies. The prevalence of each fantasy among each group is shown. Also, relationships between fantasies and the distribution of groups along the two principal dimensions highlighted by MCA are represented. Heterosexuals women reported fewer fantasies and showed opposite patterns of response compared to heterosexual men. There was a substantial overlapping in the fantasies reported by gay and bisexual men, while responses of lesbian and bisexual women were more differentiated. These results indicate that the content of sexual fantasies varies according to both gender and sexual orientation.

Abstract
INTRODUCTION The best method for administering testosterone replacement therapy (TRT) for late-onset hypogonadism (LOH) remains controversial. This study aimed to compare the efficacy and safety of a combined treatment (CT) involving intramuscular testosterone injection and testosterone ointment application [Glowmin® (GL)] with intramuscular injection monotherapy (IMIM). MATERIALS AND METHODS Patients were randomly assigned as follows: Group 1 received IMIM for 12 weeks and CT for 12 weeks and Group 2 received CT for 12 weeks and IMIM for 12 weeks. Patients were then asked about their treatment preferences: (A) IMIM, (B) a combination of IMIM and ointment, or (C) either A or B. RESULTS Patients (n = 43) completed the study without any adverse effects. No significant differences between each treatment period were found. In Group 1, most patients chose B (n = 13) while in Group 2, most chose A (n = 10). In each group, patients preferred the second treatment phase; however, statistical significance was not reached between A and B (Group 1, p = 0.11 and Group 2, p = 0.47, respectively). CONCLUSION TRT by CT is compatible with TRT by IMIM. Patients who cannot continue TRT because of polycythemia from IMIM may be suited to CT.

Abstract
Deviant sexual fantasy is identified as a risk factor for sexual offending, yet no study has examined deviant sexual fantasy across the lifespan in nonoffending adult males. To bridge this gap, this study examined the frequencies of normative and deviant sexual fantasies among 318 nonoffending adult males in the United States. Participants were recruited via Amazon Mechanical Turk™. Participants took two inventories that assessed demographics and types of sexual fantasies. Normality tests, means tests, Kruskal-Wallis 1-way analyses of variance (ANOVAs), binary logistic regressions, and odds ratio post hoc analyses were conducted. Deviant sexual fantasies progressively declined across all three age groups, while normative sexual fantasy did not. Results suggest that deviant sexual fantasy changes across the lifespan. Applicability of the findings to applied settings, such as sexually violent predator evaluations, is discussed. Limitations and future considerations are addressed.

Abstract
The goal of this study was to investigate the association between serum oestradiol levels and clinically significant erectile dysfunction in a cohort of men presenting for andrological evaluation. Retrospective review was conducted of patients that presented to a urologist with practice in andrology over an 18-month period. Patients completed the Male Sexual Health Questionnaire and had serum total testosterone and oestradiol measurements prior to 10:30 a.m. via immunoassay. t Tests, chi-square tests and multivariate logistic regression were used to compare clinical characteristics between those with adequate erectile function (erection scale score > 2) vs. clinically significant erectile dysfunction (erection scale score ≤ 2). Among 256 patients, average age was 49 years (SD 15), average serum oestradiol was 22.3 pg/ml (SD 10.6), and average serum total testosterone was 465.9 pg/ml (SD 206.3). On multivariate logistic regression, serum oestradiol was associated with clinically significant erectile dysfunction (OR 1.52 per SD increase, 95% CI 1.11-2.09, p = 0.009) when controlling for serum total testosterone, age, body mass index and smoking status. These results warrant future studies on the utility of measuring serum oestradiol in patients with erectile dysfunction and the use of aromatase inhibitors in patients with erectile dysfunction and elevated serum oestradiol.

Abstract
Erectile dysfunction (ED) due to androgen deficiency is rare in the young population. We retrospectively evaluated in this study men aged 18-40 years presenting with ED from 2015 to 2017. The International Index of Erectile Function-5 (IIEF-5) and Erection Hardness Grade Scores (EHGS) were used to assess erectile function. Total testosterone (TT), sex hormone-binding globulin (SHBG), lipid profile, and glycometabolic indicators were tested in fasting blood sample. TT and SHBG were detected by electrochemiluminescence immunoassay, and free (FT) and bio-available testosterone (BT) were calculated from a validated formula. Linear regression was used to analyze the data. In total, 140 cases (30.56 ± 4.81 years) with a mean TT levels of 6.15 ± 2.17 ng/ml were enrolled. Decreased levels of FT were associated with lower IIEF-5 scores(β = 0.176, P = 0.048) and EHGS (β = 0.198, P = 0.026) after adjustment for age, body mass index (BMI), smoking, comorbidities, high-sensitive C-reactive protein (hsCRP), uric acid, fructosamine, and quantitative insulin sensitivity check index (QUICKI). TT was only associated with EHGS in the crude model (β = 0.177, P = 0.037) and some single factor adjustment models, whereas BT and SHBG were not related with erectile function in any model. Low FT level, even in the presence of normal TT, is associated with ED severity in young men. FT levels should be screened in ED patient even with normal total testosterone.

Abstract
Objectives Determination of free testosterone (FT) serum level is an efficient method to evaluate bioavailable testosterone. We analyzed the behavior of serum FT in patients with prostate cancer receiving androgen deprivation therapy (ADT) and correlated FT with total testosterone (TT). We also analyzed the efficiency of both isoforms in the evaluation of the ADT. Methods Serum levels of TT and FT were determined in 191 patients with prostate cancer in a cross-sectional study. A subset of 56 patients submitted only to radical prostatectomy served as control group. The remaining 135 patients with advanced prostate cancer on three-month LHRH agonist treatment comprised the study group. The median age of the population was 73 years (range, 53–86 years) and the median time on ADT was 42 months (6–198). Results A significant correlation and linear regression between TT and FT was observed (r2 0.948). The efficiency of TT and FT to discriminate patients with and without ADT was similar (AUC: 0.993 and 0.995, respectively, p>0.05). A castration level of serum FT established at 1.7 pg/mL had a sensitivity of 85.9% and a specificity of 100%, which are similar to the sensitivity and specificity of 50 ng/dL of TT. All patients without ADT had levels of serum TT and FT above the castration level. In 19 of the 135 (14.1%) patients on ADT serum TT was above 50 ng/dL. In 12 of these 19 patients (63.2%) serum FT was below 1.7 pg/mL while in seven patients (5.2%) FT was also above the castration level. Conclusions The castration level of FT was established at 1.7 pg/mL. Serum TT and TF correlated very well; however, they seemed to provide complementary information in the evaluation of ADT efficiency. 14.1% of the patients on ADT failed to reach the castration level of serum TT; determination of serum FT in these patients would reduce this rate to 5.2%.

Abstract
OBJECTIVE To analyze the impact of age, BMI and sex hormone on aging males' symptoms (AMS) and the 5-item version of the international index of erectile function (IIEF-5) scores in middle-aged and elderly Chinese men. METHODS A population-based cross-sectional study was conducted in Jiashan County. A total of 969 men, aged between 40 and 80 years old, were admitted. Physical examination and the sex hormones were measured, and AMS and IIEF-5 scores were assessed. RESULTS The oneway ANOVA analysis indicated older age groups had higher AMS total-scores, somatic and sexual sub-scores, and lower IIEF5 scores (all p < .01). Pairwise correlation (rpairwise) analyses showed the significant associations between AMS and age or sex hormone (cFT, Bio-T, SHBG, and LH) levels, and similar for IIEF5. However, when age was adjusted, the correlation coefficients (rpartial) weakened, and correlation significance disappeared, except LH (for AMS: rpartial = 0.096, p = .009; for IIEF-5: rpartial = -0.140, p = .001). Multiple linear regressions confirmed the influence of increased age and LH on the AMS and IIEF5 scores. CONCLUSION CFT, Bio-T and SHBG failed to yield any additional predicting information when age was adjusted. To improve the male reproductive health, future research should pay more attention on aging-related comorbidities and how to improve general wellness.

Abstract
BACKGROUND Although delayed ejaculation (DE) is typically characterized as a persistently longer than anticipated or desired time to ejaculation (or orgasm) during sexual activity, a timing-based definition of DE and its association with serum testosterone has not been established in a large cohort. AIM To examine in an observational study estimated intravaginal ejaculatory latency time (IELT) and masturbatory ejaculation latency time (MELT) in men self-reporting DE, assess the association of IELT and MELT with serum testosterone levels, and determine whether correlation with demographic and sexual parameters exist. METHODS Men who resided in the United States, Canada, and Mexico were enrolled from 2011 to 2013. Self-estimated IELT and MELT were captured using an Ejaculatory Function Screening Questionnaire in a sample of 988 men screened for possible inclusion in a randomized clinical trial assessing testosterone replacement therapy for ejaculatory dysfunction (EjD) and who self-reported the presence or absence of DE and symptoms of hypogonadism. Additional comorbid EjDs (ie, anejaculation, perceived decrease in ejaculate volume, and decreased force of ejaculation) were recorded. Men with premature ejaculation were excluded from this analysis. IELT and MELT were compared between men self-reporting DE and men without DE. The associations of IELT and MELT with serum testosterone were measured. OUTCOMES IELT, MELT, and total testosterone levels. RESULTS Sixty-two percent of screened men self-reported DE with or without comorbid EjDs; 38% did not report DE but did report at least one of the other EjDs. Estimated median IELTs were 20.0 minutes for DE vs 15 minutes for no DE (P < .001). Estimated median MELTs were 15.0 minutes for DE vs 8.0 minutes for no DE (P < .001). Ejaculation time was not associated with serum testosterone levels. Younger men and those with less severe erectile dysfunction had longer IELTs and MELTs. CLINICAL IMPLICATIONS Estimated ejaculation times during vaginal intercourse and/or masturbation were not associated with serum testosterone levels in this study; thus, routine androgen evaluation is not indicated in these men. STRENGTHS AND LIMITATIONS This large systematic analysis attempted to objectively assess the ejaculation latency in men with self-reported DE. Limitations were that ejaculation time estimates were self-reported and were queried only once; the questionnaire did not distinguish between failure to achieve orgasm and ejaculation; and assessment of DE was limited to heterosexual vaginal intercourse and masturbation. CONCLUSION IELT and MELT were longer in men with DE, and there was no association of ejaculation times with serum testosterone levels in this study population.

Abstract
Sexual dysfunctions are common, but underrecognized, in patients with chronic kidney disease (CKD) and are inversely associated with the glomerular filtration rate (GFR). Sexual dysfunctions may affect quality of life in males with CKD. The aim of this study was to analyze the relationship among sex hormones, sexual function, and sexual satisfaction in a group of men between 18 and 50 years of age with CKD Stages 1 to 5 not treated with hemodialysis or peritoneal dialysis. Fasting blood samples for hemoglobin, testosterone, prolactin, and luteinizing hormone and questionnaire surveys (Sexual Complaints Screener for Men, International Index of Erectile Function, and Aging Male Symptom scale) were evaluated in 100consecutive men. Higher CKD stage (i.e., lower renal function) had a statistically significant ( p < .01) correlation with lower total testosterone, free testosterone, and hemoglobin levels, and higher luteinizing hormone and prolactin levels. Sexual function/dysfunctions were not significantly associated with CKD stage, even after adjustment for age and serum testosterone. The results indicate that CKD stage is a factor affecting testosterone levels in combination with age in men between 18 and 50 years of age at different stages of CKD but not treated with hemodialysis or peritoneal dialysis. Sexual dysfunctions are common but not strongly correlated to testosterone levels, prolactin levels, and survey (Sexual Complaints Screener for Men, International Index of Erectile Function, and Aging Male Symptom scale) responses in patients with CKD.

Abstract
Erectile dysfunction and low sexual desire are multifactorial diseases. The decrease in testosterone levels is one of the causes, but the effect of estradiol is not well known. Moreover, study has shown that the testosterone/estradiol ratio has more influence over sexuality than does estradiol alone. The aim of the study was to determine whether the balance between testosterone and estradiol has any relation to some aspects of sexual function. It was an ambispective study of 230 patients with urological problems unrelated to sexuality. They underwent a detailed history and hormone study including total, free, bioavailable testosterone and estradiol. They completed the Sexual Health Inventory for Men and questions 11 and 12 of the IIEF15 were used to assess impairment in sexual desire. The T/E ratio was calculated, and the relationship between the different parameters and erectile function and sexual desire were studied by univariate and multivariate analysis. The mean age was 66.32 ± 8.17 years. The percentage of patients with erectile dysfunction was 60.9% (7% severe, 14.3% moderate, 12.6% mild to moderate and 27% mild) and decreased sexual desire was 46.5%. Age, free and biodisponible testosteron were the only variables with a positive linear association with erectile dysfunction and decreased sexual desire. Age was the only independent variable for both, erectile dysfunction and sexual desire, in the multiple linear regression. There was no association between a testosterone/estradiol imbalance and an alteration in erectile function and sexual desire. Consequently, in the clinical study of these patients, it is not necessary to request estradiol in the laboratory analyses.

Abstract
Delayed ejaculation (DE) is probably least studied, and least understood of male sexual dysfunctions, with an estimated prevalence of 1–4% of the male population. Pathophysiology of DE is multifactorial and including psychosexual-behavioral and cultural factors, disruption of ejaculatory apparatus, central and peripheral neurotransmitters, hormonal or neurochemical ejaculatory control and psychosocial factors. Although knowledge of the physiology of the DE has increased in the last two decade, our understanding of the different pathophysiological process of the causes of DE remains limited. To provide a systematic update on the pathophysiology of DE. A systematic review of Medline and PubMed for relevant publications on ejaculatory dysfunction (EjD), DE, retarded ejaculation, inhibited ejaculation, and climax was performed. The search was limited to the articles published between the January 1960 and December 2015 in English. Of 178 articles, 105 were selected for this review. Only those publications relevant to the pathophysiology, epidemiology and prevalence of DE were included. The pathophysiology of DE involves cerebral sensory areas, motor centers, and several spinal nuclei that are tightly interconnected. The biogenic, psychogenic and other factors strongly affect the pathophysiology of DE. Despite the many publications on this disorder, there still is a paucity of publications dedicated to the subject.

Abstract
AIM To develop a management strategy (rehabilitation programme) for erectile dysfunction (ED) after radiotherapy (RT) or androgen deprivation therapy (ADT) for prostate cancer that is suitable for use in a UK NHS healthcare context. METHODS PubMed literature searches of ED management in this patient group together with a survey of 28 experts in the management of treatment-induced ED from across the UK were conducted. RESULTS Data from 19 articles and completed questionnaires were collated. The findings discussed in this article confirm that RT/ADT for prostate cancer can significantly impair erectile function. While many men achieve erections through PDE5-I use, others need combined management incorporating exercise and lifestyle modifications, psychosexual counselling and other erectile aids. This article offers a comprehensive treatment algorithm to manage patients with ED associated with RT/ADT. CONCLUSION Based on published research literature and survey analysis, recommendations are proposed for the standardisation of management strategies employed for ED after RT/ADT. In addition to implementing the algorithm, understanding the rationale for the type and timing of ED management strategies is crucial for clinicians, men and their partners.

Abstract
Androgens are essential for the development and growth of the genitalia. They regulate the erectile physiology by multiple mechanisms. Several studies have examined associations among sex hormones' serum levels, erectile function and sex drive. We sought to identify a protocol for using testosterone in men with erectile dysfunction and late-onset hypogonadism (LOH). During a 16-month period, men with erectile dysfunction who presented to the andrology clinic were selected. They underwent a complete physical examination and filled out the International Index of Erectile Function-5 questionnaire. Serum luteinising hormone (LH) and testosterone levels were evaluated. Patients received a single intramuscular injection of 250 mg testosterone. Thereafter, serum levels of LH and testosterone were measured 3 weeks later. The mean age was 53 years old. After treating patients with testosterone, 45 (94%) showed improvement in LOH symptoms including libido, loss of energy, irritability and quality of life. The mean International Index of Erectile Function was 9 and 13.1, prior to and after treatment respectively. Mean serum testosterone levels before and after treatment were 4.2 and 4.1 ng ml(-1) respectively (P = 0.849). Mean serum LH revealed a significant decrease after the study (P = 0.004) (6.12 and 5.1 ng ml(-1) , before and after the study respectively). Our findings suggested that testosterone replacement therapy improves libido and LOH symptoms in individuals with almost normal or lower limit normal value of serum testosterone levels.

Abstract
INTRODUCTION A better understanding of ejaculatory disorders has led to an increasing interest in nonpremature ejaculatory dysfunction (non-PE EjD). Current reviews on the subject use a symptom-based classification to describe ejaculatory dysfunction even when it is a single case report. While these reviews provide important information on the disorder, a clearer picture of the prevalence of non-PE EjD in relation to the community and various pathophysiologic states is needed. OBJECTIVES The objective of this study was to provide a systematic review of studies of non-PE EjD excluding single case reports. METHODS A systematic review of Medline for terms including ejaculation, orgasm or hematospermia. Association with terms delay, pain or headache was made. The search was restricted to male gender and articles written in English. Abstracts were reviewed and those mainly concerned with premature ejaculation were excluded. RESULTS A total of 333 articles on non-PE EjD were identified. The condition was reported in community-based studies. In certain patient populations, non-PE EjD was commonly reported in association with antidepressant and antipsychotic treatments, in patients with chronic prostatitis/chronic pelvic pain syndrome, patients with lower urinary tract symptoms particularly in association with medical or surgical treatment, patients with retroperitoneal surgery and in patients with neurological diseases. Few articles were concerned with treatment options. CONCLUSION There is a significant prevalence of non-PE EjD in the community and in association with particular disease states or as a side effect of medical or surgical interventions. There is a need to direct efforts to prevent and treat these conditions.

Abstract
Testosterone is important in the physiology of various organs and tissues. The serum testosterone concentration gradually declines as one of the processes of aging. Thus, the concept of late-onset hypogonadism has gained increasing attention in the last few years. Reported symptoms of late-onset hypogonadism are easily recognized and include diminished sexual desire and erectile quality, particularly in nocturnal erections, changes in mood with concomitant decreases in intellectual activity and spatial orientation, fatigue, depression and anger, a decrease in lean body mass with associated decreases in muscle volume and strength, a decrease in body hair and skin alterations, and decreased bone mineral density resulting in osteoporosis. Among these various symptoms, sexual dysfunction has been the most common and necessary to treat in the field of urology. It is well known that a low serum testosterone level is associated with erectile dysfunction and hypoactive sexual libido and that testosterone replacement treatment can improve these symptoms in patients with hypogonadism. Recently, in addition to sexual dysfunction, a close relationship between metabolic syndrome, characterized by central obesity, insulin resistance, dyslipidemia, and hypertension, and late-onset hypogonadism has been highlighted by several epidemiologic studies. Several randomized control trials have shown that testosterone replacement treatment significantly decreases insulin resistance in addition to its advantage for obesity. Furthermore, metabolic syndrome is one of the major risk factors for cardiovascular disease, and a low serum testosterone level is closely related to the development of atherosclerosis. Presently, it is speculated that a low serum testosterone level may increase the risk for cardiovascular disease. Thus, testosterone is a key molecule in men's health, especially that of elderly men.

Abstract
BACKGROUND Symptoms of the "male climacteric" are often at least in part referred to an age-dependent decline of serum androgen levels. Therefore, we evaluated the relationship of climacteric symptoms as assessed by the "Aging Males' Symptoms" (AMS) Questionnaire with circulating androgen levels. METHODS 146 ambulatory men (age, 27-85 years) were surveyed with the AMS Questionnaire and sampled for serum values of total testosterone (tT) and sexual hormone binding globulin (SHBG). Free testosterone (fT) was calculated from tT and SHBG. A total AMS score ≥37 was considered pathological; the lower limits for tT and fT were set to 8 nmol/l and 180 pmol/l, respectively. RESULTS A significant deficit in tT and fT was shown in 25 (17.1%) and 34 (24.5%) men, respectively; the AMS Questionnaire showed pathological results for 66 (45.2%) men. In predicting a tT deficit, the AMS Questionnaire rendered a sensitivity of 76% and a specificity of 61.6%, only. However, multiple regression analysis revealed a significant correlation of lowered tT with a pathological somatovegetative and psychological AMS subscore (p = 0.042 and p = 0.01) and a correlation of lowered fT with a pathological sexual subscore (p = 0.039). CONCLUSION In predicting hypogonadism the AMS Questionnaire in total did not render a sufficient diagnostic efficiency.

Abstract
BACKGROUND Testosterone is essential for the regulation of erectile physiology, but the relationship between low testosterone and erectile dysfunction (ED) has not been firmly established. PURPOSE To examine the association between serum total, free and bio-available testosterone and ED in a population-based sample. METHODS A consecutive series of 1776 men aged 20-77 participated in the routine physical examination from September 2009 to December 2009 in Guangxi, China. ED was assessed using the five-item International Index of Erectile Function (IIEF-5) questionnaire. Total testosterone (TT), sex hormone binding globulin (SHBG) and other biochemical profiles were measured. Free testosterone (FT) and bio-available testosterone (BT) were calculated based on Vermeulen's formula. Data were collected with regard to smoking, alcoholic drinking, physical activity and metabolic syndrome. RESULTS The prevalence of ED (IIEF-5<22) was 47.6%. Men with ED were significantly older, and more prone to smoke cigarettes (≥20 cigarettes/day) or drink alcohol (≥3 drinks/week), and more likely to have elevated blood pressure (P = 0.036) or hyperglycemia (P<0.001) compared with those without ED. The significant increase in SHBG with age was parallel to its increase with increasing severity of ED (P<0.001). The obscure increase in TT across the ED status was detected without significance (P = 0.418), but TT was positively associated with ED after adjustment for age [odds ratio (OR) = 1.02, 95% CI (confidence internal): 1.00-1.04]. FT and BT were inversely associated with ED (OR = 0.14, 95%CI: 0.06-0.33; OR = 0.92 (95%CI: 0.89-0.96, respectively) in the univariate analysis, and this inverse association appeared to be independent of smoking status, alcoholic drinking, physical activity, hyper-triglyceridemia and hyperglycemia. CONCLUSIONS FT and BT are inversely related to worsening ED, whereas the positive association between TT and ED is most likely due to the increase in SHBG.

Abstract
Many patients with prostate cancer for whom androgen deprivation therapy (ADT) is indicated are young and desire to remain sexually active. In such patients, the side effects of androgen therapy on sexual function can be a source of serious reduction in overall quality of life. Providing the appropriate treatment options in this patient population is therefore essential. Nevertheless, treating such patients is challenging and an understanding of the underlying mechanisms of sexual physiology and pathophysiology is crucial to optimal patient care. In this paper, we reviewed what was known regarding the effects of ADT on sexual function in animal models and we also provided a detailed review on the effects of ADT on sexual health in humans and its treatment.

Abstract
BACKGROUND The time of ovulation has since long been believed to be concealed to male heterosexual partners. Recent studies have, however, called for revision of this notion. For example, male testosterone concentrations have been shown to increase in response to olfactory ovulation cues, which could be biologically relevant by increasing sexual drive and aggressiveness. However, this phenomenon has not previously been investigated in real-life human settings. We therefore thought it of interest to test the hypothesis that males' salivary testosterone concentrations are influenced by phases of their female partners' menstrual cycle; expecting a testosterone peak at ovulation. METHODS Thirty young, healthy, heterosexual couples were recruited. During the course of 30-40 days, the women registered menses and ovulation, while the men registered sexual activity, physical exercise, alcohol intake and illness (confounders), and obtained daily saliva samples for testosterone measurements. All data, including the registered confounders, were subjected to multiple regression analysis. RESULTS In contrast to the hypothesis, the ovulation did not affect the testosterone levels, and the resulting testosterone profile during the menstrual cycle was on the average flat. The specific main hypothesis, that male testosterone levels on the day of ovulation would be higher than day 4 of the cycle, was clearly contradicted by a type II error(β)-analysis (< 14.3% difference in normalized testosterone concentration; β = 0.05). CONCLUSIONS Even though an ovulation-related salivary testosterone peak was observed in individual cases, no significant effect was found on a group level.

Abstract
Androgens, the levels of which decrease with ageing, play many physiological roles in various organs. Testosterone deficiency syndrome (TDS) has received widespread attention in the last several years. First-line treatment for TDS should be testosterone replacement therapy (TRT), which is reported to improve several TDS symptoms. Recently, a clinical practice manual for TDS was written and published by a collaborative team from the Japanese Urological Association and the Japanese Society for the Study of the Aging Male to recommend standard procedures for the diagnosis, treatment, prevention and monitoring of adverse reactions to TRT and for post-treatment assessment. In this manual, intramuscular injection of testosterone enanthate or human chorionic gonadotropin and the testosterone gel 'Glowmin' were recommended as TRT. Currently, two topics related to TDS are being focused on in Japan: the relationship between TDS and metabolic syndrome and treatment options for eugonadal patients with TDS symptoms. In this review, the possibility of TRT for metabolic syndrome as well as the relationship between testosterone and adiponectin, which is a key molecule in metabolic syndrome, is discussed. Finally, the possibility of herbal medicines as a treatment option for patients with TDS is addressed, especially for eugonadal patients, because eugonadal men with TDS symptoms account for approximately 30% of the general population. The increase in the levels of several cytokines, such as IL-8, IL-13, interferon-γ and tumor necrosis factor-α, after herbal medicine treatment may be the reason for this efficacy.

Abstract
The aim of this study was to evaluate the main predictive factors of male sexual desire, considering medical, psychological, and relationship factors. The study assessed 205 men from the general population on the following variables: psychological adjustment, dysfunctional sexual beliefs, automatic thoughts and emotions during sexual activity, dyadic adjustment, and the presence of medical conditions. Regarding cognitive and emotional factors, restrictive attitudes toward sexuality (β = -.27), lack of erotic thoughts during sexual activity (β = -.35), concerns about erection (β = -.26), emotions of sadness (β = -.23), and shame (β = -.23) in a sexual context were significant predictors of sexual desire. Dyadic adjustment and the presence of medical conditions were not significant predictors of male sexual desire. A multiple regression analysis including all these variables, in addition to age, indicated that lack of erotic thoughts during sexual activity was the only significant predictor of sexual desire (β = -.28). These findings suggest the importance of cognitive dimensions in sexual desire, particularly the role of attentional focus and lack of erotic thoughts during sexual activity.

Abstract
OBJECTIVES To investigate clinical features of Chinese patients with severe primary erectile dysfunction (S-PED) and to identify the ideal treatment options for this population. METHODS Patients with PED were screened for enrollment in our study. Sexual history, marital status, and erectile function were evaluated by inquiry including International Index of Erectile Function-5. Individuals with severe PED (defined as refractory to management with phosphodiesterase type 5 inhibitor [PDE5i]) underwent serum hormone analysis, penile color duplex Doppler ultrasound, neuroelectromyogram, and cavernosography as appropriate. Long-term treatment results were determined. RESULTS Among 220 PED patients, 72 (32.7%) suffered from severe PED (PDE5i nonresponse). Mean age was 31.5 +/- 4.5 years and mean duration of attempts at sexual activity was 2.4 +/- 3.2 years, Sixty-eight men (94.5%) had organic etiologies for erectile dysfunction, including arteriogenic (n = 13), venogenic (n = 35), endocrinologic (n = 6), neurologic (n = 9), and cavernosal fibrosis (n = 5). Sixteen men (22.2%) had been divorced. Mean erectile function and quality-of-life were significantly improved (P <.001) in the 25 men (34.7%) who were treated by penile prosthesis implantation, at a mean follow-up of 5.6 years. Satisfaction with penile prosthesis for patients and partner was 93.4% and 92.3%, respectively. CONCLUSIONS Severe PED has a major impact on young couple's life quality. Venous leak is the most common cause of severe PED. Penile prosthesis implantation is safe and effective for severe PED.

Abstract
PURPOSE Sexual function in male lymphoma survivors was examined and compared with that of age-matched controls. PATIENTS AND METHODS This cross-sectional study included serum gonadal hormone levels (testosterone, sex hormone-binding globulin, luteinizing hormone [LH], and follicle-stimulating hormone) and responses to questionnaires assessing sexual function (Brief Sexual Function Inventory [BSFI]), socioeconomic factors, quality of life, emotional distress, and fatigue. The lymphoma group included 246 men < or = 50 years old at diagnosis who were diagnosed from 1980 to 2002 and treated at the Norwegian Radium Hospital. For each lymphoma survivor, two age-matched controls (n = 492) were drawn from a normative sample with BSFI scores. RESULTS The lymphoma survivors had a mean age at survey of 47.4 years, the mean duration of follow-up was 14.8 years, and 79% lived in committed relationships. All BSFI domain scores decreased significantly with age. Lymphoma survivors having low testosterone and/or elevated LH had lower BSFI scores than survivors with normal gonadal hormones. Multivariate analyses showed that increasing age, more emotional distress, poor physical health, and low testosterone and/or elevated LH were significantly associated with reduced sexual function within the lymphoma group. Lymphoma survivors had significantly lower BSFI domain scores than did controls on erection, ejaculation, and sexual satisfaction. CONCLUSION Lymphoma survivors had significantly poorer sexual function than normative controls. It is unclear whether the abnormal hormone levels directly cause the reduced sexual function within the lymphoma group or if a mediating factor is involved, such as aging, emotional distress, or perceived health status.

Abstract
INTRODUCTION In middle-aged men, the associations between long-term depressive symptoms and circulating testosterone levels are poorly known, although it is known that testosterone levels decrease with age. METHODS A health questionnaire was mailed to a population-based sample from the National Population Register in 1998, 1999, and 2001. Based on their self-reported mental symptoms, a total of 116 men were selected for clinical examination in 2005. Half of them had high and the others low levels of adverse mental symptoms in all three previous follow-ups. A structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-IV was performed. Depressive symptoms were assessed with the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HDRS). The Aging Males' Symptoms scale was also compiled and testosterone levels were determined. RESULTS In the entire study sample, serum free testosterone levels correlated negatively with both BDI and HDRS scores. In the hypogonadism group (based on free testosterone, 19.8% of the sample), clinically significant depression (BDI score > or = 13) was more than three times as frequent as in the other men (34.8% vs. 10.4%), the odds ratio after multiple adjustments being 4.98 (95% confidence interval 1.66-14.95). A decrease in sexual desire was common in hypogonadism (36%). Nevertheless, it also associated with clinically significant depression, irrespective of free testosterone levels. DISCUSSION Long-term and current depressive symptoms, a decreased sexual desire, and low serum free testosterone levels are associated in middle-aged men. Hypogonadism per se and as a cause of decreased sexual desire may be a contributory and possibly treatable factor underlying male depression. CONCLUSIONS The findings highlight the need for hormonal status assessment in middle-aged depressive men.

Abstract
INTRODUCTION Testosterone replacement therapy has been used in the treatment of sexual dysfunction; however, its use remains controversial, and the effectiveness and long-term health implications are unknown. AIM To evaluate the association between sex hormone serum levels, erectile function, and sexual drive in a population-based sample of men. METHODS A stratified random sample of men residing in Olmsted County, Minnesota, completed a questionnaire containing questions from the Brief Male Sexual Function Inventory (BMSFI), and participated in a clinical exam, which included serum hormone measurements. MAIN OUTCOME MEASURES Levels of sexual drive (libido) and erectile function as assessed by the BMSFI and serum testosterone, bioavailable testosterone, and estradiol measurements. RESULTS Out of 414 men, 294 had a regular sexual partner and androgen measurements at the 14th year of follow-up. Total testosterone and erectile function were significantly correlated even after adjustment for age (r = 0.12, P = 0.04). Conversely, total testosterone was not significantly correlated with sex drive (r = 0.08, P = 0.17). Bioavailable testosterone was significantly correlated with both erectile function and sex drive (r = 0.16, P = 0.01 and r = 0.20, P = 0.001, respectively). However, these associations disappeared after age adjustment (r = 0.04 and r = 0.09). CONCLUSIONS These cross-sectional results suggest the relationship between sex hormones and sexual function is complex, and that the age-related decline in sexual function may be due to age-related declines in levels of bioavailable testosterone rather than total testosterone levels.

Abstract
BACKGROUND Erectile dysfunction (ED) has a profound impact on the quality of life of many men. Many risk factors are associated with ED, such as aging, sex hormone levels, hypertension, cardiovascular diseases, and diabetes mellitus. Arsenic exposure could damage peripheral vessels and increase the risk of cardiovascular disease. However, the relationship between arsenic exposure and ED has seldom been evaluated. OBJECTIVES In this study we aimed to investigate whether exposure to arsenic enhances the risk of ED. METHODS We recruited 177 males >or= 50 years of age through health examinations conducted in three hospitals in Taiwan. We used a questionnaire (International Index of Erectile Function-5) to measure the level of erectile function. Sex hormones, including total testosterone and sex hormone-binding globulin, were determined by radioimmunoassay. We used another standardized questionnaire to collect background and behavioral information (e.g., cigarette smoking; alcohol, tea, or coffee drinking; and physical activity). RESULTS The prevalence of ED was greater in the arsenic-endemic area (83.3%) than in the non-arsenic-endemic area (66.7%). Subjects with arsenic exposure > 50 ppb had a significantly higher risk of developing ED than those with exposure <or= 50 ppb, after adjusting for age, cigarette smoking, diabetes mellitus, hypertension, and cardiovascular disease [odds ratio (OR) = 3.4]. Results also showed that the risk of developing severe ED was drastically enhanced by arsenic exposure (OR = 7.5), after adjusting for free testosterone and traditional risk factors of ED. CONCLUSIONS Results suggested that chronic arsenic exposure has a negative impact on erectile function.

Abstract
BACKGROUND Not only the most frequent causes of endocrine sexual dysfunction, such as hypogonadism and hyperprolactinemia, but almost all extragonadal endocrinopathies (hyper- and hypothyroidism, hyper- and hypocortisolism, steroidal secreting tumors, etc.) may have a greater or lesser effect on sexual function. METHODS We analyzed scientific literature on the correlations between hormones and sexual behavior, analyzing the most important issue from a practical point of view. The aim of this review article was thus to summarize the sexual symptoms that may be observed with endocrine diseases. RESULTS Hormones directly or indirectly regulate all human sexual functions (desire, erection/lubrication, ejaculation, orgasm). Some sexual symptoms may occur as a psychosomatic consequence of hormonal impairment. However, in other cases, endocrine failure may be generated by the psychosomatic involvement. CONCLUSIONS The endocrinologist, as an expert in body chemistry, is ideally positioned to identify and evaluate the full range of medical, physical, and psychiatric problems disrupting sexual function.

Abstract
To review the role and significance of hypogonadism, defined as a low testosterone (T) level, in erectile dysfunction (ED). Review of literature. Serum T is below 3 ng/ml in 12% of ED patients, including 4% before and 15% after the age of 50. Replacement studies in men with severe hypogonadism demonstrate that sexual desire and arousal, as well as the frequency of sexual activity and spontaneous erections are clearly T-dependant. Psychic erections are partly T-dependant. The effects of T upon sexual function are dose-dependant up to a threshold level that is consistent within an individual, but markedly variable between individuals, ranging from 2 to 4.5 ng/ml. More evidence is required to confirm a significant impact of T on the intrapenile vascular mechanisms of erections in men as it is the case in animals. No convincing association of T with ED has been found in epidemiological studies. As concerns clinical experience, although a meta-analysis of the randomized controlled trials established that T therapy consistently restores erectile function in young hypogonadal patients with T below 3.46 ng/ml, the effects of this treatment have been mostly disappointing when used alone in older patients consulting for ED who are subsequently diagnosed to have hypogonadism following routine T measurement. These poor results may probably be explained by the high prevalence of co-morbidities, and by the fact that ED itself may induce hypogonadism. Combination therapy with T and PDE5 inhibitor (PDE5I) may be effective in the hypogonadal ED patients when T therapy alone fails. However, more evidence is required to confirm the hypothesis that a minimum level of T is required for a complete effect of PDE5I in certain men, since a PDE5I was able to restore complete erections in severely hypogonadal men. Though a low T level is not always the only cause of ED in hypogonadal ED patients, there are important benefits in screening for hypogonadism in ED. A low T level justifies a 3 month trial of T therapy, before combining a PDE5I if T therapy alone fails.

Abstract
PURPOSE There is a growing body of evidence in the literature correlating erectile dysfunction to obesity. We investigated the correlation of different anthropometric indexes of central obesity to erectile dysfunction. MATERIALS AND METHODS A cross-sectional study was performed including 256 consecutive men 40 years old or older. All men completed the International Index of Erectile Function, and were evaluated routinely with a clinical history, physical examination and blood analysis for fasting serum glucose, lipid profile and serum testosterone. Anthropometric measures included body mass index, waist circumference, sagittal abdominal diameter, maximal abdominal circumference, and waist-hip, waist-thigh, waist-height, sagittal abdominal diameter-thigh and sagittal abdominal diameter-height indexes. RESULTS In men 40 to 60 years old the different anthropometric indexes of central obesity were not correlated with the presence of erectile dysfunction (p > 0.05). Men older than 60 years (41%, range 61 to 81) demonstrated an association among erectile dysfunction and waist-hip index (p = 0.04), waist-thigh index (p = 0.02), sagittal abdominal diameter (p = 0.03), sagittal abdominal diameter-height index (p = 0.02) and maximal abdominal circumference (p = 0.04). After logistic regression analysis an independent effect on the presence of erectile dysfunction was observed for waist-hip index (OR 8.56, 95% CI 1.44-50.73), sagittal abdominal diameter (OR 7.87, 95% CI 1.24-49.75), sagittal abdominal diameter-height index (OR 14.21, 95% CI 1.11-182.32), maximum abdominal circumference (OR 11.72, 95% CI 1.73-79.18) and waist circumference (OR 19.37, 95% CI 1.15-326.55). CONCLUSIONS This study suggests that central obesity, assessed by several anthropometric indicators, is associated to the presence of erectile dysfunction in men older than 60 years. Sagittal abdominal diameter, sagittal abdominal diameter-height index, maximum abdominal circumference, waist circumference and waist-hip index were useful indicators to predict the presence of erectile dysfunction.

Abstract
OBJECTIVE To investigate the frequency of hypogonadism in men with erectile dysfunction (ED) and to assess which factors are related with low testosterone levels. PATIENTS AND METHODS In all, 165 men with ED were assessed; the evaluation included: hormonal profiles, serum total and free testosterone (using Vermeulen's formula) levels, and self-reported questionnaires on erectile function and desire domains of the International Index of Erectile Function. The frequency of hypogonadism was established using total and free testosterone levels as diagnostic criteria. The factors that might influence testosterone levels were evaluated by univariate and multivariate statistical analysis, and a logistic regression was used to determine which factors can predict free testosterone levels below normal limits (biochemical hypogonadism). RESULTS Using the total testosterone levels, 4.8% of the men were hypogonadal, whereas when using the free testosterone levels, 17.6% were hypogonadal. In the univariate analyses, not smoking and hypertension were associated with lower total and free testosterone levels. Ageing, absence of nocturnal erections and a lower erectile function score were only associated with lower free testosterone serum levels. There was no association between total and free testosterone levels and desire. In the multivariate analysis, only total testosterone levels were related to hypertension, while free testosterone levels were related to age and nocturnal erections. For biochemical hypogonadism, simple logistic regression analysis selected age, erectile function score and aetiological diagnosis of ED as predictors. In the multivariate analysis only the erectile function score had significant independent prognostic value. CONCLUSIONS The frequency of hypogonadism is higher when free testosterone levels are used for diagnosis. The total and free testosterone levels were not related to the level of sexual desire in men with ED. The free testosterone levels could be related to the quality and frequency of nocturnal erections, and when ED is more severe, it is more probable that free testosterone levels are below the 'normal' limit.

Abstract
The association between hypogonadism, quality of life (QoL), and erectile dysfunction (ED) among the middle-aged and aged male in Taiwan is evaluated. A total of 680 study subjects aged >or=40 years old were recruited from Northern (n=276), Middle (n=238), and Southern (n=202) Taiwan, respectively. ED was diagnosed by score of International Index of Erectile Function (IIEF-5). Taiwan version questionnaire for QoL includes domain 1 (physical domain), domain 2 (psychological domain), domain 3 (social relationship domain), and domain 4 (environmental domain) was used to measure QoL. Blood hormones, including FSH, LH, Prolactin, SHBG, total testosterone (TT), calculated free testosterone (cFT), and bioavailable testosterone (Bio-T), were determined. Logistic regression analysis was used to estimate crude and multivariate-adjusted odds ratio of risk factors and its 95% confidence interval. A significantly inverse association between concentration of serum cFT and Bio-T, and severity of ED was observed. Scores of QoL of Domain 1-4 were significantly decreased with the increament of severity of ED. Significant correlations were found between IIEF scores and four domains of QoL, respectively. After adjustment for age, cFT and Bio-T, study subjects with ED (IIEF<or=21) would have significantly high risk of low level of QoL in four domains. In conclusion, a significant association between low levels of serum calculated cFT, Bio-T, and severity of ED was found. In addition, abnormal erectile function significantly associated with low level of QoL in four domains.

Abstract
The change in sexual hormones with age in middle-aged and elderly Chinese men, with and without erectile dysfunction (ED), was investigated. Total testosterone (TT), free testosterone (FT), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG) were determined from fasting serum samples by radioimmunoassay in 627 middle-aged and elderly ethnic Chinese men with and without ED. Calculated FT was derived from TT and SHBG. Patients with ED were subdivided into groups having low serum TT (<2.7 ng/ml) and normal TT (> or =2.7 ng/ml). FT and DHEAS declined and SHBG rose with age in both normal patients and in patients with ED. TT and SHBG were lower in patients with ED than in normal subjects at all ages. In contrast to findings in previous studies, levels of FT were higher in patients with ED than in normal subjects. Hormonal changes in this Chinese population generally mirrored those in previously studied ethnic populations, except for higher FT in patients with ED. This suggests that hormonal levels in patients with ED may vary in different populations. The significance and reproducibility of this finding remains to be determined.

Abstract
Prevalence and severity of erectile dysfunction (ED) increase with aging and are often associated with illnesses, like diabetes mellitus, heart disease, and hypertension, pathologically characterized by endothelial dysfunction and whose prevalence increases with age. The assumption that ED is mainly a neurovascular disease is supported by the evidence that specific phosphodiesterase type 5 (PDE5) inhibition produces an efficient erection in a wide range of ages and conditions. The availability of specific PDE5 inhibitors has enabled the development of effective treatment strategies, in this contest, tadalafil may be considered as the least "typical" PDE5 inhibitor. In clinical trials, tadalafil significantly enhanced, in patients of different ages, all efficacy outcomes across disease etiologies and severities. With an effectiveness lasting up to 36h, tadalafil allows patients to choose when to have sexual activities without the need to time it, showing positive feedback in terms of quality of life related to the treatment. Headache and dyspepsia were the most frequent side-effects of tadalafil, followed by back pain, nasal congestion, myalgia, and flushing, but the impact that long time action could have on effectiveness and safety is not yet entirely defined. The aim of this article is to critically review the available evidence from the tadalafil clinical research program and give the physician a rational approach for intervention in the treatment of ED and related diseases.

[PMID: 16040104 DOI: 10.1016/j.urology.2005.03.050] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2005] [Revised: 02/24/2005] [Accepted: 03/22/2005] [Indexed: 11/22/2022]
Abstract
OBJECTIVES To investigate the influence of treatment for testicular cancer on the pituitary-gonadal axis and sexual function in long-time survivors after unilateral orchiectomy. METHODS Blood was drawn from patients treated for testicular cancer during routine oncologic follow-up for measurement of luteinizing hormone, follicle-stimulating hormone, sexual hormone-binding globulin, testosterone, and bioavailable testosterone. Sexual function was evaluated using the International Index of Erectile Function 15-item (IIEF-15) questionnaire. Patients were grouped according to treatment: group 1 followed a surveillance strategy, group 2 received two cycles of carboplatin monotherapy, and group 3 underwent cisplatin, etoposide, and bleomycin chemotherapy. RESULTS No statistically significant difference was found in the serum hormonal levels among the three groups, and all hormonal levels were within the 95% confidence range, except for follicle-stimulating hormone. The median serum testosterone level was 3.5 ng/mL in group 1, 3.9 ng/mL in group 2, and 4.2 ng/mL in group 3. In group 1, the median IIEF-15 score was 64.0, and the median Erectile Function (EF) domain score was 28. The median scores in groups 2 and 3 were 62.5 for IIEF-15 and 27.5 for EF and 65.0 for IIEF-15 and 30.0 for EF, respectively. No correlation was found between testosterone level and IIEF-15 or EF score. CONCLUSIONS None of the treatments investigated had a significant influence on the serum hormonal levels in long-time survivors of testicular cancer. Patients undergoing chemotherapy have no greater risk of developing a hormonal disorder than those following a surveillance strategy, and therapy for testicular cancer is not a risk factor for erectile dysfunction.
