The severity of andropause symptoms and its relationship with social well-being among retired male nurses: a preliminary cross-sectional study. BMC Geriatr 2024; 24:184. [PMID: 38395767 PMCID: PMC10893613 DOI: 10.1186/s12877-024-04805-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 02/13/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Andropause is a syndrome that occurs due to decreased androgen levels in men. Various aspects of health, such as social well-being, can affect andropause status during men's retirement. This study aimed to determine the severity of andropause symptoms and its relationship with social well-being among retired male nurses. METHODS This preliminary cross-sectional study was conducted on 284 retired male nurses in Ardabil (northwest of Iran). The participants were selected through the census sampling method. Data were collected using a demographic information form, the Male Andropause Symptoms Self-Assessment Questionnaire (MASSQ), and the Social Well-Being Scale (SWBS). Data were analyzed using SPSS software (version 22.0). RESULTS The study found that the overall mean scores of the severity of andropause symptoms and social well-being among retired male nurses were 57.24 ± 12.62 (range = 35-91) and 94.54 ± 12.77 (range = 75-123), respectively. The highest and lowest mean scores between dimensions of social well-being were related to social contribution (20.26 ± 2.47) and social acceptance (15.26 ± 2.77), respectively. Multiple linear regression analysis revealed that subscales of social well-being, age, marital status, and spouse's menopause were predictors of the severity of andropause symptoms among retired male nurses. The selected predictors accounted for 53.1% of the total variance in severity of andropause symptoms (F = 36.613, p < 0.001). CONCLUSION The results showed a moderate to severe prevalence of andropause among retired male nurses and a significant association between andropause and social well-being. The study suggests further research to examine sexual orientation and other factors that may affect andropause in retired male nurses.

Abstract
OBJECTIVE To investigate non-urological patients with multiple comorbidities for factors contributing towards differences in testosterone concentration in multiethnic Malaysian men. DESIGN An observational study. PATIENTS Sexually active men, ≥40 years, with no known urological problems, were recruited at the phlebotomy clinic at our centre. MEASUREMENTS A brief history along with latest fasting lipid profile and plasma glucose levels were obtained. An Aging Male Symptoms questionnaire was administered; waist circumference (WC) and serum testosterone concentration were measured. STATSTICAL ANALYSIS Analysis of testosterone concentration between Malay, Indian and Chinese men was performed. Statistical tests such as analysis of variance, χ2 test, univariate and multivariable regression were performed. Any p < .05 was noted as statistically significant. RESULTS Among the 604 participants analysed, mean testosterone concentration was significantly lower in Malays (15.1 ± 5.9 nmol/L) compared to the Chinese (17.0 ± 5.9 nmol/L) and Indian (16.1 ± 6.5 nmol/L) participants. The mean WC was also found to be higher among the Malays (96.1 ± 10.9 cm) compared to Chinese (92.6 ± 9.6 cm) and Indians (95.6 ± 9.9 cm). Testosterone concentration tended to be lower with higher age, but this was not statistically significant (p > .05). In the multivariable analysis only Malay ethnicity, WC ≥ 90 cm and low high-density lipoprotein (HDL) were associated with lower testosterone concentration. CONCLUSION In this study, Malaysian men of Malay origin had lower testosterone concentration compared with Indian and Chinese men. WC and low HDL were also associated with lower testosterone concentrations.

Abstract
OBJECTIVE The purpose of the study was to investigate the association between andropause symptoms and sickness absence in Japanese male workers over 2 years. METHODS A baseline survey asking about andropause symptoms, along with blood sampling for testosterone level, was conducted in June 2009. A total of 418 men (mean age = 52.4 years, SD = 8.6) participated and were followed through 2011. Hazard ratios (HRs) and 95% confidence intervals (CIs) for sickness absence were calculated using Cox proportional hazard models. RESULTS During the follow-up period, 31 of 35 participants who took sickness absences had physical illnesses. A higher andropause symptom score was associated with an increased risk of sickness absence. Testosterone deficiency (<350 ng/dL) was not associated with sickness absence. Among the subscales of andropause symptoms, the somatic symptom score was positively associated with sickness absence, whereas testosterone deficiency combined with high sexual symptoms was not associated with sickness absence. Results were similar when limited to sickness absence because of physical illness. No significant interaction between andropause symptoms and testosterone deficiency was found. CONCLUSIONS Non-specific andropause symptoms unrelated to testosterone deficiency were positively associated with sickness absence.

Abstract
INTRODUCTION Andropause is a complicated process in men's life which can negatively affect their quality of life in both physical and psychological dimensions. OBJECTIVES The aim of this study was to determine the prevalence of andropause among Iranian men age 40-85 years and its relationship with quality of life. MATERIALS AND METHODS This was a cross-sectional study among 393 men attending ten urban healthcare centers in Ilam province in southwestern Iran. Study participants were recruited using proportional random sampling. The Male andropause symptoms self-assessment questionnaire (MASSQ) and SF-12 were used for data collection. Data were analyzed using SPSS version 22 (Chicago, IL). RESULTS The mean (SD) of participants scores in MASSQ was 57.46 (17.56). Only 61 (15.5%) men were classified at "don't need testosterone" category based on MASSQ. There were significant associations between the eight aspects of HRQoL and the andropause severity (p < .001). Older age, lower education, having depression, coronary heart disease, and incontinence were associated with increased odds of andropause (p < .05). CONCLUSION This study confirmed findings of previous studies regarding andropause and its relationship with men's quality of life. Future studies in this topic are needed to discover all the factors that may influence men andropause.

Abstract
The aim of this study is to investigate the expression of the luteinizing hormone/choriogonadotropin (LHCG) receptor in the human penis to see, if the luteinizing hormone (LH) effects are possible in the spongious and cavernous tissue of the penis. The number of men with erection disturbances increases significantly simultaneously with the elevated LH concentrations between 40 and 70 years. It is possible that the elevated LH concentrations may influence locally the erectile mechanisms. The precondition for this is the expression of LHCG receptors in the penis. Penile tissue was obtained from three patients undergoing total or partial penectomy due to a rectal cancer with secondary penile metastasis or squamous cell carcinoma of the penis. Immunohistochemistry was used for the detection of the LHCG receptor. Positive immunoreaction for LHCG receptors was discovered in the endothelial cells of cavernous spaces in the corpus cavernosum and corpus spongiosum penis, also in the endothelial cells of the capillary walls in all patients. Our results show that LHCG receptor is expressed in the spongious and cavernous tissue of the human penis. This finding suggests that LH can affect the spongious and cavernous tissue in human and play a significant role in the development of erectile dysfunction among the aging men.

Abstract
BACKGROUND The androgen deficiency in the aging male (ADAM) affects physical, sexual, and psychological aspects with characteristics symptoms of middle-aged men. The practice of regular physical activity and physical exercise can attenuate these symptoms. The aim of this randomized clinical trial is to propose a physical exercise protocol based on concurrent training for middle-aged men with ADAM. METHOD Randomized clinical trial with a 6-month intervention will randomly divided into two groups: experimental group (EG) and control group (CG). Four evaluations will be carried out, (1) pre-intervention; (2) in the first month of intervention; (3) in the third month of intervention; (4) post-intervention, evaluating: physical, psychological, sexual, and hormonal aspects. The intervention protocol with concurrent training will have duration of 6 months; frequency of 3 times weekly, with 60 min per session. The two-way ANOVA test will be used for the inter-group and intra-group comparisons with repeated measurements, and also Sydak's comparison test. CONCLUSION This protocol was developed with the intent of easing the symptoms of ADAM. In addition, it is believed that the concurrent training protocol could be capable to recover hormonal, physical, psychological, and sexual aspect of middle-aged men with ADAM.

Abstract
The objective of this study was to characterise the status of health-related quality of life (HRQOL) in Japanese men with late-onset hypogonadism (LOH) treated with testosterone replacement therapy (TRT). HRQOL in 69 consecutive Japanese men with LOH undergoing TRT for at least 6 months was prospectively evaluated before and 6 months after the initiation of TRT using the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8). All eight-scale scores except for bodily pain (BP) in the 69 patients at 6 months after the introduction of TRT significantly improved compared with those before TRT; however, all scale scores except for BP in the 69 patients were significantly inferior to those in age-matched Japanese controls irrespective of the timing of SF-8. Multivariate analyses of several parameters revealed that both age and Aging Male Symptom (AMS) score had an independent impact on mental health (MH), despite the lack of an independent association between any score and the remaining factors examined. TRT appeared to significantly improve the status of HRQOL in men with LOH; however, even after the introduction of TRT, HRQOL associated with MH remained significantly impaired in elderly men and/or those with a high AMS score.

Abstract
Background Low total testosterone (TT) and sex hormone-binding globulin (SHBG) concentrations have been associated with the metabolic syndrome (MetS) in men, but the reported strength of association varies considerably. Objectives We aimed to investigate whether associations differ across specific subgroups (according to age and body mass index (BMI)) and individual MetS components. Data sources Two previously published meta-analyses including an updated systematic search in PubMed and EMBASE. Study Eligibility Criteria Cross-sectional or prospective observational studies with data on TT and/or SHBG concentrations in combination with MetS in men. Methods We conducted an individual participant data meta-analysis of 20 observational studies. Mixed effects models were used to assess cross-sectional and prospective associations of TT, SHBG and free testosterone (FT) with MetS and its individual components. Multivariable adjusted odds ratios (ORs) and hazard ratios (HRs) were calculated and effect modification by age and BMI was studied. Results Men with low concentrations of TT, SHBG or FT were more likely to have prevalent MetS (ORs per quartile decrease were 1.69 (95% CI 1.60-1.77), 1.73 (95% CI 1.62-1.85) and 1.46 (95% CI 1.36-1.57) for TT, SHBG and FT, respectively) and incident MetS (HRs per quartile decrease were 1.25 (95% CI 1.16-1.36), 1.44 (95% 1.30-1.60) and 1.14 (95% 1.01-1.28) for TT, SHBG and FT, respectively). Overall, the magnitude of associations was largest in non-overweight men and varied across individual components: stronger associations were observed with hypertriglyceridemia, abdominal obesity and hyperglycaemia and associations were weakest for hypertension. Conclusions Associations of testosterone and SHBG with MetS vary according to BMI and individual MetS components. These findings provide further insights into the pathophysiological mechanisms linking low testosterone and SHBG concentrations to cardiometabolic risk.

Abstract
Background: Andropause is a condition of decreasing testosterone in men that usually begins to occur at about 40 years of age. Many men find it difficult to acknowledge there may be a problem by refusing to even talk about the symptoms. Aims: The study was conducted to the standards of MASSQ (2012) within male older adults to introduce a relevant criterion. Materials and Methods: About 382 men with age range of 50-80 and with the mean age of 65.3 ± 2.32 were sampled with the cluster-ratio sampling method from the eight cities of Khuzestan province in southwestern Iran. The aged samples replied to the 25 items of MASSQ. Results: Coefficients of Cronbach's alpha (α = 0.89), split-half (0.91), convergent validity (0.72), divergent validity (−0.32), and criterion validity (0.67) were estimated, which were significant at P < 0.01. The exploratory factor analysis demonstrated that the 25-items of MASSQ for aged samples are organized into four factors (sexual, somatic, psychic, and behavioral) which clarify 79% of the scale's variance. Second-order confirmatory factor analysis pointed out that the factors are well-matched up onto a principal factor. Consequently, the four-factor model was well appropriate for the data by the fit index techniques for adjusting the scale [adjusted goodness of fit index = 0.92, goodness-of-fit statistic = 0.91, root mean square error of approximation = 0.006, incremental fit index = 0.94, normed fit index = 0.91, comparative fit index = 0.97]. Conclusions: The results pointed to the well-adjusted reliability and validity of MASSQ and its usefulness for the relevant studies as well.

Abstract
Many aging male suffer various andropause symptoms including loss of physical and mental activities. This study evaluated the putative alleviative effects of CRS-10 dandelion and rooibos extract complex (CRS-10) on the symptoms of andropause. The survival rate of TM3 Leydig cells (TM3 cells) treated with CRS-10 was measured based on typical physiological stress. After daily intake of CRS-10 for 4 weeks, the level of testosterone, physical activity and both the number and activity of sperm in older rats (18 weeks) were measured. Furthermore, thirty males were surveyed with AMS (Aging Males' Symptoms) questionnaire after intake of 400 mg of CRS-10. Overall, CRS-10 protected TM3 cells from serum restriction and oxidative stress via activation of ERK and Akt pathways. The level of testosterone and activation of spermatogenesis in rats were significantly enhanced. In addition, physical locomotion was markedly improved. Daily intake of 400 mg of CRS-10 improved the quality of life among agingmale respondents, according to a clinical survey using the AMS. The results indicate the potential of CRS-10 as a safe and efficacious natural substance for reducing or alleviating andropause symptoms.
