Hypogonadism is associated with overt depression symptoms in men with erectile dysfunction

The association of hypogonadism with depression and its treatments

According to World Health Organization estimates, 5% of the adult population worldwide suffers from depression. In addition to the affective, psychomotor and cognitive symptoms which characterize this mood disorder, sexual dysfunction has been frequently reported among men suffering from depression. The most common sexual manifestations are decreased libido, erectile dysfunction and orgasmic disorder. In addition, epidemiological studies have documented a reduction of testosterone concentrations in men with depression and, for these reasons, depressive disorders appear as one possible cause of male functional hypogonadism. Moreover, some largely used antidepressant medications can cause or worsen sexual complaints, thus depression and its treatments rise several andrological-relevant issues. The other way round, men with hypogonadism can manifest depressed mood, anxiety, insomnia, memory impairment which, if mild, may respond to testosterone replacement therapy (TRT). However, the prevalence of functional hypogonadism in depression, and of depressive symptoms in hypogonadal men, is not known. Severe depressive symptoms do not respond to TRT, while the effect of treating major depression on functional hypogonadism, has not been investigated. Overall, the clinical relevance of each condition to the other, as well as the physiopathological underpinnings of their relationship, are still to be clarified. The present review summarizes current evidence on the influence of testosterone on mood and of depression on the hypothalamic-pituitary-testis axis; the clinical association between male hypogonadism and depression; and the reciprocal effects of respective treatments.

The Temporal Association of Depression and Anxiety in Young Men With Erectile Dysfunction

BACKGROUND

Erectile dysfunction (ED) is a multidimensional sexual disorder that is being increasingly diagnosed in younger men. Although mental illnesses such as depression and anxiety are known risk factors for ED, the association between these conditions and ED has been understudied in young men.

AIM

To explore the temporal association between depression, anxiety, and ED in a population-based cohort of young men.

METHODS

Using 2009-2018 MarketScan Commercial Claims data, we identified all men with ED aged 18-40 years (cases). Using ICD-9/-10 codes and prescription data, we evaluated the prevalence and incidence of depression and anxiety in this cohort. Cases were matched with men without a diagnosis of ED (controls) based on age, Charlson Comorbidity Index, history of hypertension, geographic region, and year of presentation. We examined the prevalence of depression and anxiety within 12 months prior to ED diagnosis and incidence of depression and anxiety up to 36 months after ED diagnosis in cases vs controls. Differences between cases and controls were tested with Wilcoxon rank-sum test for numerical covariates, and chi-square test for categorical covariates. Significance was set at P < .05.

OUTCOMES

Prevalence and incidence of depression and anxiety in young men with and without ED.

RESULTS

Within the 12-month period preceding ED diagnosis, the prevalence of depression and anxiety in cases vs controls were 17.1% vs 12.9%, respectively (P < .001). The incidence of depression and anxiety were higher amongst cases vs controls at 12- (11.7% vs 6.3%), 24- (14.5% vs 9.0%,) and 36- (15.9% vs 10.6%) months following ED diagnosis (P < .001).

CLINICAL IMPLICATIONS

High incidence and prevalence of depression and anxiety in young men diagnosed with ED highlight the importance of normalizing mental health screenings and routine psychiatric follow-up in this population.

STRENGTHS & LIMITATIONS

Our contemporary, case-control study utilizes a population-based cohort of young men with ED to study the temporal association between depression, anxiety, and ED, which is understudied to date. The MarketScan commercial claims database used in this analysis includes men covered by private insurers only and lacks data on symptoms and treatments.

CONCLUSION

Young men with ED had significantly higher rates of depression and anxiety both before and after ED diagnosis in comparison to young men without ED. Manalo TA, Biermann HD, Patil DH, et al.

Erectile Dysfunction is a Modifiable Risk Factor for Major Depressive Disorder: Analysis of a Federated Research Network

BACKGROUND

Erectile dysfunction is one of many conditions associated with depression, but few studies exist to establish the risk of major depressive disorder (MDD) in the large population of men with erectile dysfunction, and it is unclear whether erectile dysfunction (ED) treatment is associated with decreased rates of MDD.

AIM

We determined the risk of major depressive disorder in men with erectile dysfunction and evaluated whether treatment of ED with phosphodiesterase-5 inhibitor or penile prosthesis is associated with a lower risk of developing major depressive disorder.

METHODS

We reviewed a large, retrospective, cohort that utilized electronic health record data collected by the TriNetX Research Network, a global federated database that provides healthcare data for analysis. We performed multiple comparisons: men with ED against men without ED; men with ED treated with phosphodiesterase-5 inhibitors against untreated ED patients, and of men with ED who received penile prosthesis against those who did not. We assessed major depressive disorder (ICD-10-CM F32-F33) as a primary outcome and used propensity score matching to control for ethnicity, race, type 2 diabetes mellitus (E11), essential hypertension (I10), acute myocardial infarction (I21), chronic ischemic heart disease (I25), cerebral infarction (I63), overweight and obesity (E66), personal history of nicotine (Z87.891), hypogonadism (E29.1), and alcohol related disorders (F10).

OUTCOMES

We assessed new diagnosis of major depressive disorder (F32-F33) within a 3-year time window following index event of ED diagnosis, visit to healthcare organization, or ED treatment with phosphodiesterase-5 inhibitor or penile prosthesis as the primary outcome.

RESULTS

ED was associated with major depressive disorder both before and after (OR 2.00, 95% CI 1.94-2.06) controlling for confounding variables through propensity score matching. Men who received ED therapies had lower rates of depression compared to those who did not, whether they were treated with phosphodiesterase-5 inhibitor (0.80, 0.77-0.83) or penile prosthesis (0.73, 0.60-0.89).

STRENGTHS AND LIMITATIONS

Strengths include a large sample size and robust statistical techniques. Limitations include lack of detailed information regarding clinical severity and socioeconomic factors.

CLINICAL IMPLICATIONS

Our findings indicate that clinicians should consider evaluating depressive symptoms among men with erectile dysfunction and counsel them regarding the risk of developing major depressive disorder.

CONCLUSIONS

Erectile dysfunction is associated with major depressive disorder, but treatment is associated with decreased rates of MDD. S Nackeeran, A Havanur, J Ory, et al.

Evaluation of erectile dysfunction in patients with asthma

OBJECTIVES

The aim of the current study was to investigate Erectile dysfunction (ED) in asthma patients without comorbidity and the relationship between the level of asthma control and ED.

METHODS

Forty male patients aged 24-50 years with controlled-to-uncontrolled asthma and 20 healthy volunteers were included in this study. The International Index of Erectile Function Questionnaire (IIEF) for ED was used.

RESULTS

Evaluation of the IIEF scores for ED showed that 23 (57.5%) of the asthma patients and 4 (20.0%) of the controls had various degrees of ED, and the difference was statistically significant. In total, 25% of asthma patients had mild ED, 22.5% moderate ED, and 10% severe ED. Severe, moderate and mild ED was more frequent in the asthma group. Of the 23 patients who had various degrees of ED, 13 were in the uncontrolled asthma group. While all asthma patients with severe ED were in the uncontrolled asthma group, of the 9 asthma patients with moderate ED, 6 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and one was in the controlled asthma group. Additionally, of the 10 asthma patients with mild ED, 3 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and 5 were in the controlled asthma group.

CONCLUSION

The current study showed that ED is frequent and more severe in asthma patients than controls with same age. A highly negative correlation was found between ED degree and asthma control severity.

Environmental Factors-Induced Oxidative Stress: Hormonal and Molecular Pathway Disruptions in Hypogonadism and Erectile Dysfunction

Hypogonadism is an endocrine disorder characterized by inadequate serum testosterone production by the Leydig cells of the testis. It is triggered by alterations in the hypothalamic–pituitary–gonadal axis. Erectile dysfunction (ED) is another common disorder in men that involves an alteration in erectile response–organic, relational, or psychological. The incidence of hypogonadism and ED is common in men aged over 40 years. Hypogonadism (including late-onset hypogonadism) and ED may be linked to several environmental factors-induced oxidative stresses. The factors mainly include exposure to pesticides, radiation, air pollution, heavy metals and other endocrine-disrupting chemicals. These environmental risk factors may induce oxidative stress and lead to hormonal dysfunctions. To better understand the subject, the study used many keywords, including “hypogonadism”, “late-onset hypogonadism”, “testosterone”, “erectile dysfunction”, “reactive oxygen species”, “oxidative stress”, and “environmental pollution” in major online databases, such as SCOPUS and PUBMED to extract relevant scientific information. Based on these parameters, this review summarizes a comprehensive insight into the important environmental issues that may have a direct or indirect association with hypogonadism and ED in men. The study concludes that environmental factors-induced oxidative stress may cause infertility in men. The hypothesis and outcomes were reviewed critically, and the mechanistic approaches are applied through oxidant-sensitive pathways. This study also provides reccomendations on future therapeutic interventions and protective measures against such adverse environmental factors-induced hypogonadism and ED.

The Steroidogenesis Inhibitor Finasteride Reduces the Response to Both Stressful and Rewarding Stimuli

Finasteride (FIN) is the prototypical inhibitor of steroid 5α-reductase (5αR), the enzyme that catalyzes the rate-limiting step of the conversion of progesterone and testosterone into their main neuroactive metabolites. FIN is clinically approved for the treatment of benign prostatic hyperplasia and male baldness; while often well-tolerated, FIN has also been shown to cause or exacerbate psychological problems in vulnerable subjects. Evidence on the psychological effects of FIN, however, remains controversial, in view of inconsistent clinical reports. Here, we tested the effects of FIN in a battery of tests aimed at capturing complementary aspects of mood regulation and stress reactivity in rats. FIN reduced exploratory, incentive, prosocial, and risk-taking behavior; furthermore, it decreased stress coping, as revealed by increased immobility in the forced-swim test (FST). This last effect was also observed in female and orchiectomized male rats, suggesting that the mechanism of action of FIN does not primarily reflect changes in gonadal steroids. The effects of FIN on FST responses were associated with a dramatic decrease in corticotropin release hormone (CRH) mRNA and adrenocorticotropic hormone (ACTH) levels. These results suggest that FIN impairs stress reactivity and reduces behavioral activation and impulsive behavior by altering the function of the hypothalamus-pituitary-adrenal (HPA) axis.

Association between chronic obstructive pulmonary disease and risk of erectile dysfunction: a systematic review and meta-analysis

Chronic obstructive pulmonary disease (COPD) is a common chronic disease. Mounting evidence shows that male patients with COPD have an increased risk of developing erectile dysfunction (ED). The aim of this meta-analysis was to assess the relationship between COPD and the risk of ED. To identify relevant studies, the PubMed, Cochrane Library and Embase databases, Chinese Biomedical Literature (CBM), China National Knowledge Infrastructure (CNKI) were systematically searched up to September 2018. Relative risks (RR) and corresponding 95% confidence intervals (CI) were used to estimate the strength of association between COPD and the risk of ED by using random-effects models. Finally, four studies (three cross-sectional, one cohort study) involving 58,307 participants were included. Synthesis results demonstrated that patients with COPD was not significantly associated with an increased overall prevalence of ED (RR = 1.31, 95% CI: 0.95-1.81, P = 0.099) compared to the healthy controls. However, the subgroup analyses showed that the prevalence of moderate ED (RR = 2.44, 95% CI: 1.29-4.59, P = 0.006) and severe ED (RR = 2.77, 95% CI: 1.57-4.94, P = 0.001) were significantly higher in patients with COPD. Evidence from this meta-analysis revealed that patients with COPD had a significantly increased susceptibility to moderate and severe ED, which should remind both clinicians and patients to be aware of the potential hazardous effect of COPD for developing ED.

Evaluation of the effectiveness and safety of a daily dose of 5 mg of tadalafil, over an 8-week period, for improving quality of life among Korean men with andropause symptoms, including erectile dysfunction: A pilot study

BACKGROUND

The primary aim of this study was to evaluate the effects of a once-a-day 5 mg dose of tadalafil, prescribed for 8 weeks, on the quality of life (QoL) of South Korean men with andropause symptoms, including erectile dysfunction (ED), using a single group, open-labeled, before-and-after preliminary trial. The secondary objective was to evaluate the effectiveness and safety of tadalafil for ED.

METHODS

Forty South Korean men (>35 years of age) with andropause symptoms including ED were enrolled into our trial. Andropause syndrome was defined using the androgen deficiency in aging males (ADAM) questionnaire and other screening tests, including testosterone levels. The following outcome measures were obtained at baseline and at 4 and 8 weeks of tadalafil treatment: physical examination, adverse effects, Short Form 12 Health Survey (SF-12) score, International Index of Erectile Function (IIEF-5) score, bioelectrical impedance analysis (BIA), and free radical testing.

RESULTS

Treatment increased the SF-12 Mental component score, used as a proxy measure of quality of life, from baseline to at 4 and 8 weeks (P < .05). In addition, the mean IIEF-5 score, which assesses sexual function, increased from baseline at 4 and 8 weeks (P < .05), with this increase being significant at both time points. No adverse effects were noted.

CONCLUSION

Tadalafil (5 mg dose, once daily) is a safe and effective treatment to improve ED, and overall QoL, among Korean men with andropause symptoms, including ED.

Testosterone promotes anxiolytic-like behavior in gonadectomized male rats via blockade of the 5-HT1A receptors

This study was designed to examine an anxiety-like behavior in the adult gonadectomized (GDX) male rats subjected to testosterone propionate (TP) treatment alone or in combination with 8-OH-DPAT, a 5-HT_1A receptor agonist, or with NAN-190, 5-HT_1A receptor antagonist. Two weeks after gonadectomy, GDX rats were subjected by treatments with the solvent, TP (0.5mg/kg, s.c.), 8-OH-DPAT (0.05mg/kg, s.c.), NAN-190 (0.1mg/kg, i.p.), TP in combination with 8-OH-DPAT or NAN-190 during 14days. Anxiety behavior was assessed in the elevated plus maze (EPM) and the open field test (OFT). 8-OH-DPAT treatment failed to modify the anxiety-like behavior of GDX rats in the EPM as compared to the GDX rats given with oil solvent. NAN-190 injected alone or in combination with TP to GDX rats resulted in a significant anxiolytic-like effect as compared to the GDX given with oil solvent or TP application. Our data indicate that the combination of NAN-190 and TP is more effective than TP alone in GDX rats inducing a more profound anxiolytic-like effect in the EPM. Thus, the results of this study suggest that effects of 5-HT_1A receptor agonist/antagonist can modify anxiety level in opposite direction in male rats after gonadectomy.

No effect of testosterone on behavior in aged Wistar rats

In men, aging is accompanied by a gradual decline in androgen secretion. Studies suggest beneficial effects of endogenous and exogenous testosterone on affective behavior and cognitive functions. The aim of this study was to describe behavioral and cognitive sex differences and to analyze the effects of long-term androgen deficiency in aged male rats. Thirty-months old rats divided into three groups (males, females and males gonadectomized as young adults) underwent a battery of behavioral tests assessing locomotor activity, anxiety, memory, anhedonia, sociability and depression-like behavior. No major effect of gonadectomy was found in any of the analyzed behavioral measures in male rats. The only consistent sex difference was confirmed in depression-like behavior with longer immobility time observed in males. In an interventional experiment, a single dose of testosterone had no effect on gonadectomized male and female rats in the forced swim test. In contrast to previous studies this comprehensive behavioral phenotyping of aged rats revealed no major role of endogenous testosterone. Based on our results long-term hypogonadism does not alter the behavior of aged male rats, neither does acute testosterone treatment. Whether these findings have any consequences on androgen replacement therapy in aged men remains to be elucidated.

The Role of Somatic Symptoms in Sexual Medicine: Somatization as Important Contextual Factor in Male Sexual Dysfunction

INTRODUCTION

An important feature of somatic symptom disorder is the subjective perception of the physical symptoms and its maladaptive interpretation. Considering that psychological distress is often expressed through somatic symptoms, it is possible that they underlie at least a part of the symptoms in subjects complaining of sexual dysfunction. Nevertheless, studies on the impact of somatoform disorders in sexual dysfunction are scanty.

AIM

To define the psychological, relational, and organic correlates of somatic symptoms in a large sample of patients complaining of sexual problems.

METHODS

A consecutive series of 2833 men (mean age 50.2 ± 13.5 years) was retrospectively studied.

MAIN OUTCOME MEASURES

Somatic symptoms were assessed using the "somatized anxiety symptoms" subscale of the Middlesex Hospital Questionnaire (MHQ-S). Several clinical, biochemical, psychological, and relational parameters were studied. Patients were interviewed with the previously validated Structured Interview on Erectile Dysfunction (SIEDY), and ANDROTEST (a structured interview for the screening of hypogonadism in patients with sexual dysfunction).

RESULTS

Among the 2833 patients studied, subjects scoring higher on somatic symptoms were older, more obese, reporting unhealthy lifestyle (current smoking, alcohol consumption), and a lower education (all P < .05). Moreover, they reported a general impairment of their sexuality more often, including erectile problems (spontaneous or sexual-related), low sexual desire, decreased frequency of intercourse, and perceived reduction of ejaculate volume (all P < .005). Interestingly, we observed a significant association between MHQ-S scoring with a reduced testosterone level and hypogonadism symptoms (both P < .05). Finally, we found a significant association between somatic symptoms and both SIEDY Scales 1 (organic domain of ED) and 3 (intrapsychic domain of ED) (both P < .0001).

CONCLUSION

The present study demonstrates that the presence of somatic symptoms can represent an important contextual factor in the determination of or in the exacerbation of male sexual dysfunction. High levels of somatic symptoms in subjects with sexual dysfunction can be related to the sexual symptom itself. The consequences of this pattern have great clinical relevance in a sexual medicine setting, considering their severe impact on sexuality.

Prevalence of Sexual Dysfunction and Associated Risk Factors in Middle-Aged and Elderly Korean Men in Primary Care

Although several studies have individually investigated the risk factors for erectile dysfunction (ED), premature ejaculation (PE), and late-onset hypogonadism (LOH), few studies have considered ED, PE, and LOH as categories of sexual dysfunction (SD) within the same population. We therefore aimed to investigate the prevalence of SD and its associated risk factors among men in primary care. Study participants were enrolled by 18 family physicians from 15 hospital-based family practices in Korea between August 2010 and May 2011. Participants answered a questionnaire regarding their demographic characteristics and lifestyle factors as well as the Korean versions of the Androgen Deficiency in the Aging Male, the International Index of Erectile Function, and the Premature Ejaculation Diagnostic Tool questionnaires. SD prevalence was 64.9% among study participants who were ≥ 40 years of age. ED prevalence was 43.7%, PE prevalence was 38.6%, and LOH prevalence was 16.8%. SD prevalence was significantly associated with increased age, overweight, hypertension, diabetes, and depression. These findings highlight the importance of screening questions for SD in primary care, especially among older male patients with the identified risk factors.

The association between erectile dysfunction, depressive symptoms and testosterone levels among middle-aged men

Aims: The aim of this study was to investigate the association between erectile dysfunction and depressive symptoms and testosterone levels among middle-aged men at the community level. Methods: The study population consisted of 614 men born in 1945 and living in the city of Oulu, Finland. Erectile dysfunction was assessed by the erectile function domain of the International Index of Erectile Function questionnaire and depressive symptoms by the Beck Depression Inventory. Blood samples were collected to measure testosterone and sex hormone-binding globulin level. Results: After adjusting for confounders, erectile dysfunction was statistically significantly associated with depressive symptoms (risk ratio (RR) 1.66, 95% confidence interval (95% CI) 1.29–2.15), as well as with obesity (RR 1.72, 95% CI 1.12–2.62). Neither total nor free testosterone level was associated with erectile dysfunction among our study group. Conclusions: Depressive symptoms rather than testosterone levels should be taken into consideration while treating middle-aged men with erectile problems at the community level.

Systematic Literature Review of the Epidemiology of Nongenetic Forms of Hypogonadism in Adult Males

This study summarizes the literature on the prevalence, incidence, and proportion of patients receiving treatment for male hypogonadism and a systematic literature search was performed for articles published in the last 20 years. Of the 97 studies identified, 96 examined the prevalence, 2 examined the incidence, and 4 examined the proportion of males with hypogonadism patients receiving treatment. Based on studies conducted in Europe and USA, the prevalence of hypogonadism in the general population ranged from 2.1% to 12.8% of middle-aged to older men, with an estimated incidence of 12 new cases per 1,000 person-years. Prevalence was higher among patients with comorbid conditions, such as type 2 diabetes mellitus and obesity. Approximately 10–12% of men with hypogonadism were receiving testosterone treatment. This literature review suggests that there is potentially a significant burden of hypogonadism in the general population. Burden seems to increase with age and in the presence of certain disease conditions. Data suggests that many hypogonadal men who may benefit from testosterone replacement are not receiving treatment. This may be the result of underdiagnosis of the disease, lack of awareness by patients or physicians, irregularities surrounding the diagnostic criteria, and deficiency of long-term safety studies.

Erectile dysfunction and sex hormone changes in chronic obstructive pulmonary disease patients

Background

The prevalence of sexual dysfunction in patients with COPD is high and its significance has not been sufficiently stressed. The aim of this study is to investigate the incidence of erectile dysfunction (ED) and the factors affecting its frequency in COPD patients.

Methods

Seventy patients with COPD and 68 healthy volunteers were included in the study. The International Index of Erectile Function questionnaire was used to evaluate ED, and the Beck Depression Inventory was used to evaluate depression.

Results

The smoking rate was higher and oxygen saturation (SaO₂) and body mass index (BMI) were lower in the COPD group. Blood tests revealed higher levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol. Testosterone level was lower but it was not statistically significant. Various degrees of ED were detected in 78.6% of COPD patients and 55.8% of the controls. Depression was more common in the COPD group. There was a negative correlation between forced expiratory volume in 1 sec (FEV1) level and ED and between SaO₂ and ED in the COPD group. A positive correlation was noted between age and ED in both groups. No significant correlation was found among hormonal status and FEV₁, ED, depression, SaO₂, or BMI.

Conclusions

The present study provides further confirmation that COPD is a risk factor for erectile dysfunction. When establishing a treatment plan for improving the pulmonary function of COPD patients, sexual dysfunction and depression, which are usually neglected but diminish quality of life, should also be addressed.

The effect of testosterone supplementation on depression symptoms in hypogonadal men from the Testim Registry in the US (TRiUS)

OBJECTIVE

To determine the effect of long-term testosterone replacement therapy (TRT) on depression symptoms in hypogonadal men.

METHODS

Data were from TRiUS, a multicenter, 12-month observational registry (N = 849) of hypogonadal men prescribed 1% testosterone gel. Measures including total testosterone (TT) were assessed at baseline and months 3, 6, and 12. Depression symptoms were measured with Patient Health Questionnaire-9 (PHQ-9), a validated self-report questionnaire. A PHQ-9 score decrease of ≥5 represents clinical improvement.

RESULTS

PHQ-9 scores were available for 762/849 TRiUS participants at baseline. Overall, 92.4% (704/762) demonstrated some level of depressive symptoms, with 17.3% (132/762) having moderately severe (score 15-19) to severe (score 20-27) symptoms. Subcohorts with significantly (p ≤ 0.03) more moderately severe to severe symptoms were: <60 years old, TT levels <250 ng/dl (<8.68 nmol/l), HIV/AIDS-positive, or used antidepressants or opioids. TT levels and PHQ-9 scores improved significantly (p < 0.01) by 3 months of TRT. At 12 months PHQ-9 scores showed a clinically meaningful mean improvement of 5.62 points, patients with moderately severe to severe symptoms decreased from 17.3% to 2.1% (5/233), and subcohorts, including those defined by age (<60 years) and antidepressant use, had improved PHQ-9 scores ≥5.

CONCLUSION

TRT may reduce depression symptoms in hypogonadal men, including middle-aged men and those using antidepressants.

Partial androgen deficiency, depression, and testosterone supplementation in aging men

The aim of this review was to summarize current knowledge on the correlation between depressive symptoms with a syndrome called partial androgen deficiency of the aging male (PADAM) and on the potential benefits of testosterone (T) treatment on mood. Despite, the causative nature of the relationship between low T levels and depression is uncertain, many hypogonadal men suffer from depression and vice versa several depressed patients are affected by hypogonadism. Supplementation with testosterone failed to show sound evidence of effectiveness in the treatment of depression. Nevertheless, testosterone supplementation has proved to be effective on some domains significant for the quality of life of aged patients with PADAM (sexual function and cognitive functions, muscular strengths).

International web survey shows high prevalence of symptomatic testosterone deficiency in men

INTRODUCTION

Though the clinical significance of testosterone deficiency is becoming increasingly apparent, its prevalence in the general population remains unrecognised. A large web-based survey was undertaken over 3 years to study the scale of this missed diagnosis.

METHODS

An online questionnaire giving the symptoms characterising testosterone deficiency syndrome (Aging Male Symptoms-AMS-scale) was set up on three web sites, together with questions about possible contributory factors.

RESULTS

Of over 10,000 men, mainly from the UK and USA, who responded, 80% had moderate or severe scores likely to benefit from testosterone replacement therapy (TRT). The average age was 52, but with many in their 40s when the diagnosis of 'late onset hypogonadism' is not generally considered. Other possible contributory factors to the high testosterone deficiency scores reported were obesity (29%), alcohol (17.3%), testicular problems such as mumps orchitis (11.4%), prostate problems (5.6%), urinary infection (5.2%) and diabetes 5.7%.

CONCLUSIONS

In this self-selected large international sample of men, there was a very high prevalence of scores which if clinically relevant would warrant a therapeutic trial of testosterone treatment. This study suggests that there are large numbers of men in the community whose testosterone deficiency is neither being diagnosed nor treated.

Hypogonadism in men with erectile dysfunction may be related to a host of chronic illnesses

The prevalence of hypogonadism has been found to be increased in certain chronic illnesses, especially diabetes, hypertension and obesity. Recently, the prevalence of hypogonadism in primary care practices mirrored that in our population of men with erectile dysfunction (ED). In this study, the prevalence of hypogonadism in nearly 1000 men with ED was tabulated, using a retrospective chart review, and analyzed for association with the various contributing medical and psychological factors. The prevalence of hypogonadism was determined in men with a variety of chronic illnesses, and was further characterized by decade. We observed an association between hypertension (P=0.025), tobacco abuse (P=0.0059), sleep apnea (P=0.0001), work stress (P=0.041) and hypogonadism. These data were further analyzed for the odds ratio and confidence interval (Forest plot), which showed strong association for sleep apnea and work stress. We did not observe any significant association between diabetes, atherosclerosis, alcohol abuse, multiple medications, asthma, seizure disorder, anxiety/depression and hypogonadism (P values for Cochran-Mantel-Haenszel general association were 0.48, 0.97, 0.25, 0.69, 0.22, 0.76 and 0.98, respectively). We suggest that a host of chronic illnesses have a high prevalence of secondary hypogonadism. Men who have chronic medical or psychological illnesses should have their testosterone level checked, especially when sexual dysfunction symptoms or signs are present.
