- Background: Few data have looked at the occurrence and clinical correlates of self-reported shorter than desired ejaculation latency (rapid ejaculation, RE) and its related distress in the general population. Aim: To determine the prevalence and clinical correlates of self-reported RE and RE- related distress in middle age and older European men. Methods: Subjects were recruited from population samples of men aged 40-79 years across 8 European centers. Outcomes: Self-reported RE and its related distress were derived from the European male Aging Study (EMAS) sexual function questionnaire (EMAS-SFQ). Beck's depression Inventory (BDI) was used for the quantification of depressive symptoms, the Short Form 36 health survey (SF-36) for the assessment of the quality of life, the International Prostate Symptom Score (IPSS) for the evaluation of lower urinary tract symptoms. Results: About 2,888 community dwelling men aged 40-79 years old (mean 58.9 ± 10.8 years) were included in the analysis. Among the subjects included, 889 (30.8%) self-reported RE. Among them, 211 (7.3%) claimed to be distressed (5.9% and 1.4% reported mild or moderate-severe distress, respectively). Increasing levels of RE-related distress were associated with a progressive worse sexual functioning, higher risk of ED and with couple impairment, along with a higher prevalence of depressive symptoms (all P < 0.05). Furthermore, a worse quality of life and higher IPSS score were associated with RE-related distress (all P < 0.05). The aforementioned results were confirmed even when patients using drugs possibly interfering with ejaculation or those without a stable relationship were excluded from the analysis. Clinical Implications: RE is a frequent condition in men from the general population; however, its related distress is relatively modest. Nonetheless, men with any degree of self-reported RE show increasing levels of depression, worse quality of life and worse couple satisfaction. Strengths & Limitations: This is the first study estimating the prevalence of self-reported RE and its related distress, along with their biological and psychological correlates, in a population sample of European middle age and older men. However, is should be recognized that the diagnosis of RE was derived from patient reports and not supported by Intra-ejaculatory-Latency-Time (IELT) measurements. Conclusion: Self-reported RE is relatively common in European men aged more than 40 years. The reported limited RE-related distress may explain the relatively low number of medical consultations for RE. RE-related distress is associated with worse sexual function, couple impairment, and more LUTS resulting in a worse quality of life and mood disturbances. Corona G, Rastrelli G, Bartfai G, et al.

- Background: Age-related chronic low-grade inflammation (inflammaging) is one of the proposed mechanisms behind sarcopenia. However, findings regarding inflammatory markers in sarcopenic older adults are conflicting. This study aimed to determine the association between inflammatory markers, prevalent as well as incident sarcopenia, sarcopenia-defining parameters, quality of life (QoL), and physical activity in middle-aged and older men. Methods: Men aged 40–79 years (mean 59.66 ± 11.00y) were recruited from population registers in eight European centres for participation in the European Male Aging study (EMAS). Subjects were assessed at baseline (2003–2005) and again after a median follow-up of 4.29 years. In 2577 participants, associations between baseline inflammatory markers [high-sensitive C-reactive protein (hs-CRP), white blood cell count (WBC), albumin] and baseline physical activity (PASE) and QoL (SF-36) were analysed. In the Leuven and Manchester cohort (n = 447), data were available on muscle mass (whole-body dual X-ray absorptiometry) and strength. In this subgroup, cross-sectional associations between baseline inflammatory markers and sarcopenia-defining parameters (handgrip strength, chair stand test, appendicular lean mass, and gait speed) and prevalent sarcopenia were examined. In a further subgroup (n = 277), associations with knee extensor strength were explored. Longitudinally, predictive value of baseline inflammation on functional decline, physical activity, QoL, and incident sarcopenia was examined. Subgroup analyses were performed in subgroups with chronic inflammation and stratified by age. Linear and logistic regressions were used, adjusted for age, body mass index, centre, and smoking. Results: At baseline, hs-CRP and WBC were negatively associated with PASE score (hs-CRP: β = −7.920, P < 0.001; and WBC: β = −4.552, P < 0.001) and the physical component score of SF-36 (hs-CRP: β = −1.025, P < 0.001; and WBC: β = −0.364, P < 0.001). Baseline WBC levels were negatively associated with gait speed (β = −0.013; P = 0.025), quadriceps isometric 90° (β = −5.983; P = 0.035) and isokinetic 60°/s peak torque/body weight (β = −5.532; P = 0.027). The prevalence of sarcopenia at baseline was 18.1% (n = 81). Of those without sarcopenia at baseline, 64 (18.6%) satisfied criteria for sarcopenia at follow-up. There were no significant associations between baseline inflammatory markers and either prevalent or incident sarcopenia, or change in level of sarcopenia-defining parameters between baseline and follow-up. Conclusions: In middle-aged and older men, hs-CRP and WBC were negatively associated with QoL and PASE scores, while WBC was negatively associated with gait speed and knee strength. Associations with hs-CRP remained significant in all ages, whereas WBC levels were only associated with PASE, gait speed and knee strength in older adults (60–79 years). Baseline inflammatory markers (hs-CRP, WBC and albumin) did not predict functional decline, decline in physical activity, decreased QoL or incident sarcopenia.

- Objective: Elevated luteinizing hormone (LH) with normal testosterone (T) suggests compensated dysregulation of the gonadal axis. We describe the natural history, risk factors and clinical parameters associated with the development of high LH (HLH, LH >9.4 U/L) in ageing men with normal T (T ≥ 10.5 nmol/L). Design, Patients and Measurements: We conducted a 4.3-year prospective observational study of 3369 community-dwelling European men aged 40-79 years. Participants were classified as follows: incident (i) HLH (n = 101, 5.2%); persistent (p) HLH (n = 128, 6.6%); reverted (r) HLH (n = 46, 2.4%); or persistent normal LH (pNLH, n = 1667, 85.8%). Potential predictors and changes in clinical features associated with iHLH and rHLH were analysed using regression models. Results: Age >70 years (OR = 4.12 [2.07-8.20]), diabetes (OR = 2.86 [1.42-5.77]), chronic pain (OR = 2.53 [1.34-4.77]), predegree education (OR = 1.79 [1.01-3.20]) and low physical activity (PASE ≤ 78, OR = 2.37 [1.24-4.50]) predicted development of HLH. Younger age (40-49 years, OR = 8.14 [1.35-49.13]) and nonsmoking (OR = 5.39 [1.48-19.65]) predicted recovery from HLH. Men with iHLH developed erectile dysfunction, poor health, cardiovascular disease (CVD) and cancer more frequently than pNLH men. In pHLH men, comorbidities, including CVD, developed more frequently, and cognitive and physical function deteriorated more, than in pNLH men. Men with HLH developed primary hypogonadism more frequently (OR = 15.97 [5.85-43.60]) than NLH men. Men with rHLH experienced a small rise in BMI. Conclusions: Elevation of LH with normal T is predicted by multiple factors, reverts frequently and is not associated with unequivocal evidence of androgen deficiency. High LH is a biomarker for deteriorating health in aged men who tend to develop primary hypogonadism.

Tidskriftsartikel (refereegranskat)abstract
- Context: The androgen receptor (AR) gene exon 1 CAG repeat length has been proposed to be a determinant of between-individual variations in androgen action in target tissues, which might regulate phenotypic differences of human ageing. However, findings on its phenotypic effects are inconclusive. Objective: To assess whether the AR CAG repeat length is associated with longitudinal changes in endpoints that are influenced by testosterone (T) levels in middle-Aged and elderly European men. Design: Multinational European observational prospective cohort study. Participants: A total of 1887 men (mean ± s.d. age: 63 ± 11 years; median follow up: 4.3 years) from centres of eight European countries comprised the analysis sample after exclusion of those with diagnosed diseases of the hypothalamic-pituitary-testicular (HPT) axis. Main outcome measures: Longitudinal associations between the AR CAG repeat and changes in androgen-sensitive endpoints (ASEs) and medical conditions were assessed using regression analysis adjusting for age and centre. The AR CAG repeat length was treated as both a continuous and a categorical (6-20; 21-23; 24-39 repeats) predictor. Additional analysis investigated whether results were independent of baseline T or oestradiol (E2) levels. Results: The AR CAG repeat, when used as a continuous or a categorical predictor, was not associated with longitudinal changes in ASEs or medical conditions after adjustments. These results were independent of T and E2 levels.

Tidskriftsartikel (refereegranskat)abstract
- Background: Social and lifestyle influences on age-related changes in body morphology are complex because lifestyle and physiological response to social stress can affect body fat differently. Objective: We examined the associations of socioeconomic status (SES) and lifestyle factors with body mass index (BMI) and waist circumference (WC) in middle-aged and elderly European men. Design and setting: Cross-sectional study of 3,319 men aged 40-79 recruited from eight European centres. Outcomes: We estimated relative risk ratios (RRRs) of overweight/obesity associated with unfavourable SES and lifestyles. Results: The prevalence of BMI 30kg/m2 or WC 102cm rose linearly with age, except in the 8th decade when high BMI, but not high WC, declined. Among men aged 40-59y, compared to non-smokers or most active men, centre and BMI adjusted RRRs for having a WC between 94-101.9cm increased by 1.6-fold in current smokers, and 2.7-fold in least active men, maximal at 2.8-fold in least active men who smoked. Similar patterns but greater RRRs were observed for men with WC≥102cm, notably 8.4-fold greater in least active men who smoked. Compared to men in employment, those who were not in employment had increased risk of having a high WC by 1.4-fold in the 40-65y group and by 1.3-fold in the 40-75y group. These relationships were weaker among elderly men. Conclusion: Unfavourable SES and lifestyles associate with increased risk of obesity, especially in middle-aged men. The combination of inactivity and smoking was the strongest predictor of high WC, providing a focus for health promotion and prevention at an early age.

- Background: Few published data link overweight and obesity with measures of quality of life (QoL) including sexual health in men. Objective: To assess the association of overweight/obesity with impairment of physical and psychological QoL and sexual functions in men. Design and setting: Cross-sectional, multicentre survey of 3369 community-dwelling men aged 40-79 (mean +/- S.D., 60 +/- 11) years randomly selected from eight European centres. Outcomes: Adiposity was assessed by body mass index (BMI) and waist circumference (WC), QoL and functional impairments by physical and psychological function domains of the Short Form-36 questionnaire, Beck's Depression Inventory and the European Male Ageing Study sexual function questionnaire. Results: Complete data on sexual activities and erectile function were available in 2734 (92%) and 3193 (95%) of the participants respectively. From the population studied, 814 men were obese (BMI >= 30 kg/m(2)) and 1171 had WC >= 102 cm, 25% of all men were unable to do vigorous activity and 2-13% reported depressive symptoms. Symptoms of sexual dysfunction ranged between 22% (low sexual desire) and 40% (infrequent morning erections) of the participants. Among obese men with both BMI >= 30 kg/m(2) and WC >= 102 cm, at least one symptom of impaired physical, psychological and sexual function was reported by 41, 43 and 73% of the participants respectively. Compared with the reference group of non-obese men (BMI < 30 kg/m(2) and WC < 102cm), men with BMI >= 30 kg/m(2) and WC >= 102 cm more frequently reported at least one symptom of impaired physical function (odds ratio (OR)=2.67; confidence interval (CI): 2.07-3.45, P < 0.001), impaired psychological function (OR=1.48; CI: 1.14-1.90, P < 0.01) and impaired sexual function (OR=1.45; CI: 1.14-1.85, P < 0.01). These functional impairments were also more prevalent in men who had WC >= 102 cm even with BMI < 30 kg/m(2), but those with BMI >= 30 kg/m(2) and WC < 102 cm generally did not suffer from increased impaired physical or sexual health. Men with high BMI and WC were at even greater likelihood of having a composite of two or more or three or more symptoms compared with those with normal BMI and WC. Conclusions: Men with high WC, including those who are 'non-obese' with BMI < 30 kg/m(2), have poor QoL with symptoms of impaired physical, psychological and sexual functions. Health promotion to improve QoL should focus on prevention of obesity and central fat accumulation.

The ESR1 (6q25) Locus Is Associated with Calcaneal Ultrasound Parameters and Radial Volumetric Bone Mineral Density in European Men
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Genome-wide association studies (GWAS) have identified 6q25, which incorporates the oestrogen receptor alpha gene (ESR1), as a quantitative trait locus for areal bone mineral density (BMDa) of the hip and lumbar spine. The aim of this study was to determine the influence of this locus on other bone health outcomes; calcaneal ultrasound (QUS) parameters, radial peripheral quantitative computed tomography (pQCT) parameters and markers of bone turnover in a population sample of European men. Methods: Eight single nucleotide polymorphisms (SNP) in the 6q25 locus were genotyped in men aged 40-79 years from 7 European countries, participating in the European Male Ageing Study (EMAS). The associations between SNPs and measured bone parameters were tested under an additive genetic model adjusting for centre using linear regression. Results: 2468 men, mean (SD) aged 59.9 (11.1) years had QUS measurements performed and bone turnover marker levels measured. A subset of 628 men had DXA and pQCT measurements. Multiple independent SNPs showed significant associations with BMD using all three measurement techniques. Most notably, rs1999805 was associated with a 0.10 SD (95%CI 0.05, 0.16; p = 0.0001) lower estimated BMD at the calcaneus, a 0.14 SD (95%CI 0.05, 0.24; p = 0.004) lower total hip BMDa, a 0.12 SD (95%CI 0.02, 0.23; p = 0.026) lower lumbar spine BMDa and a 0.18 SD (95%CI 0.06, 0.29; p = 0.003) lower trabecular BMD at the distal radius for each copy of the minor allele. There was no association with serum levels of bone turnover markers and a single SNP which was associated with cortical density was also associated with cortical BMC and thickness. Conclusions: Our data replicate previous associations found between SNPs in the 6q25 locus and BMDa at the hip and extend these data to include associations with calcaneal ultrasound parameters and radial volumetric BMD.

Comparison of serum testosterone and estradiol measurements in 3174 European men using platform immunoassay and mass spectrometry; relevance for the diagnostics in aging men
- 2012
-
Ingår i: European Journal of Endocrinology. - 1479-683X. ; 166:6, s. 983-991

Tidskriftsartikel (refereegranskat)abstract
- Background: The limitations of serum testosterone and estradiol (E-2) measurements using nonextraction platform immunoassays (IAs) are widely recognized. Switching to more specific mass spectrometry (MS)-based methods has been advocated, but directly comparative data on the two methods are scarce. Methods: We compared serum testosterone and E-2 measurements in a large sample of middle-aged/elderly men using a common platform IA and a gas chromatography (GC)-MS method, in order to assess their limitations and advantages, and to diagnose male hypogonadism. Of subjects from the European Male Aging Study (n = 3174; age 40-79 years), peripheral serum testosterone and E-2 were analyzed using established commercial platform IAs (Roche Diagnostics E170) and in-house GC MS methods. Results: Over a broad concentration range, serum testosterone concentration measured by IA and MS showed high correlation (R=0.93, P<0.001), which was less robust in the hypogonadal range (<11 nmol/l; R=0.72, P<0.001). The IA/MS correlation was weaker in E-2 measurements (R=0.32, P<0.001, at E-2 <40.8 pmol/l, and R=0.74, P<0.001, at E-2 >40.8 pmol/l). Using MS as the comparator method, IA ascertained low testosterone compatible with hypogonadism (<11 nmol/l), with 75% sensitivity and 96.3% specificity. The same parameters with IA for the detection of low E-2 (<40.7 pmol/l) were 13.3 and 99.3%, and for high E-2 (>120 pmol/l) 88.4 and 88.6%. Conclusion: A validated platform IA is sufficient to detect subnormal testosterone concentrations in the diagnosis of male hypogonadism. The IA used for E-2 measurements showed poor correlation with MS and may only be suitable for the detection of high E-2 in men.

- Context: Polymorphisms in genes involved in regulation, biosynthesis, metabolism, and actions of testicular sex hormones may influence hormone balance and phenotype of aging men. Objective: We investigated the relationships between polymorphisms in genes related to pituitary-testicular endocrine function and health status. Design and Setting: Using cross-sectional baseline data, we conducted a multinational prospective cohort observational study consisting of a population survey of community-dwelling men. Participants: A total of 2748 men, aged 40-79 (mean +/- SD, 60.2 + 11.2) yr, were randomly recruited from eight European centers. Forty-three polymorphisms were genotyped in the following genes: androgen receptor (AR), estrogen receptor-alpha and -beta (ESR1 and ESR2), steroid 5alpha-reductase type II (SRD5A2), 17alpha-hydroxylase/17,20-lyase (CYP17A1), aromatase (CYP19A1), sex hormone-binding globulin (SHBG), LH beta-subunit (LHB), and LH receptor (LHCGR). Main Outcome Measures: We measured the associations between gene polymorphisms and endocrine, metabolic, and phenotypic parameters related to aging and sex hormone action. Results: Several polymorphisms in SHBG, ESR2, AR, CYP19A1, and LHB were significantly associated with circulating levels of SHBG, LH, total, free, and bioavailable testosterone and estradiol, the LH x testosterone product, and indices of insulin sensitivity. Apart from several previously reported associations between genes affecting estrogen levels and heel ultrasound parameters, no associations existed between polymorphisms and nonhormonal variables (anthropometry, blood lipids, blood pressure, hemoglobin, prostate symptoms, prostate-specific antigen, sexual dysfunction, cognition). Conclusion: In aging men, polymorphisms in genes related to the pituitary-testicular endocrine function significantly influence circulating LH, testosterone, and estradiol levels, but the downstream effects may be too small to influence secondary phenotypic parameters.

- Context: The individual variability in the waning androgenic-anabolic functions of aging men may be influenced by the CAG repeat polymorphism in exon 1 of the androgen receptor (AR), affecting androgen sensitivity. However, findings on its phenotypic effects are inconclusive. Objective: To investigate the relationships between health status, various reproductive hormones and the AR CAG repeat length. Design: A multi-national prospective cohort observational study - cross-sectional baseline data. Setting: Population survey of community-dwelling men. Participants: Men (40-79-yr-old; n=3,369) randomly recruited from centers in eight European countries; CAG repeat analysis was performed in 2,878 men. Main outcome measures: The correlations of the CAG repeat length with selected endocrine, metabolic and phenotypic parameters related to aging and sex hormone action. Results: Only minor differences were found in CAG repeat lengths between the eight European countries. They showed significant positive association with total, free and bioavailable levels of testosterone (T) and estradiol (E2). FSH but not LH correlated inversely with CAG repeat length. Significant associations were found with bone ultrasound parameters at the calcaneus. Negative correlation was found with triglycerides, but not with other blood lipids, or with anthropometry, blood pressure, hemoglobin, insulin sensitivity, or sexual and prostatic functions. Conclusions: The AR CAG repeat length correlates significantly with serum T and E2 of aging men. Weaker transcriptional activity of the AR with longer CAG-encoded polyglutamine repeats appears to be totally or near-totally compensated for by higher T levels. The residual phenotypic correlations may reflect differences in estrogen levels/actions following aromatization of the higher T levels.
