Abstract
Acorus gramineus has a number of beneficial effects, including protective effects against age-related disorders. In this study, the effects of A. gramineus on testosterone production and andropause symptoms were evaluated. We first treated TM3 mouse Leydig cells, responsible for testosterone production, with A. gramineus aqueous extract at different concentrations. In TM3 cells, the testosterone concentration increased in a concentration-dependent manner compared with those in the control. In addition, at 400 μg/mL extract, the mRNA expression level of the steroidogenic enzyme CYP11A1 was increased. Subsequently, 23-week-old Sprague-Dawley (SD) rats exhibiting an age-related reduction in serum testosterone (approximately 80% lower than that in 7-week-old SD rats) were administered A. gramineus aqueous extract for 8 weeks. Serum total testosterone and free testosterone levels were higher and serum estradiol, prostate-specific antigen levels, and total cholesterol levels were lower in the AG50 group (A. gramineus aqueous extract 50 mg/kg of body weight/day) than in the OLD (control group). The AG50 group also showed significant elevations in sperm count, grip strength, and mRNA expression of StAR, CYP11A1, 17β-HSD, and CYP17A1 compared with those in the OLD group. In conclusion, A. gramineus aqueous extract facilitated steroidogenesis in Leydig cells, elevated testosterone levels, lowered serum estradiol and total cholesterol levels, and increased muscle strength and sperm count, thus alleviating the symptoms of andropause. These findings suggest that A. gramineus aqueous extract is a potentially effective therapeutic agent against various symptoms associated with andropause.

Testosterone therapy for functional hypogonadism in middle-aged and elderly males: current evidence and future perspectives. Hormones (Athens) 2024:10.1007/s42000-024-00587-2. [PMID: 39060901 DOI: 10.1007/s42000-024-00587-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024]
Abstract
Population aging is a global phenomenon driving research focus toward preventing and managing age-related disorders. Functional hypogonadism (FH) has been defined as the combination of low testosterone levels, typically serum total testosterone below 300-350 ng/dL, together with manifestations of hypogonadism, in the absence of an intrinsic pathology of the hypothalamic-pituitary-testicular (HPT) axis. It is usually seen in middle-aged or elderly males as a product of aging and multimorbidity. This age-related decline in testosterone levels has been associated with numerous adverse outcomes. Testosterone therapy (TTh) is the mainstay of treatment for organic hypogonadism with an identifiable intrinsic pathology of the HPT axis. Current guidelines generally make weak recommendations for TTh in patients with FH, mostly in the presence of sexual dysfunction. Concerns about long-term safety have historically limited TTh use in middle-aged and elderly males with FH. However, recent randomized controlled trials and meta-analyses have demonstrated safe long-term outcomes regarding prostatic and cardiovascular health, together with decreases in all-cause mortality and improvements in various domains, including sexual function, body composition, physical strength, bone density, and hematopoiesis. Furthermore, there are numerous insightful studies suggesting additional benefits of TTh, for instance in cardio-renal-metabolic conditions. Specifically, future trials should investigate the role of TTh in improving symptoms and prognosis in various clinical contexts, including sarcopenia, frailty, dyslipidemia, arterial hypertension, diabetes mellitus, fracture risk, heart failure, stable angina, chronic kidney disease, mood disorders, and cognitive dysfunction.

Abstract
Of all the different risk factors known to cause cardiovascular disease (CVD), age and sex are considered to play a crucial role. Aging follows a continuum from birth to death, and therefore it inevitably acts as a risk for CVD. Along with age, sex differences have also been shown to demonstrate variations in immune system responses to pathological insults. It has been widely perceived that females are protected against myocardial infarction (MI) and the protection is quite apparent in young vs. old women. Acute MI leads to changes in the population of myeloid and lymphoid cells at the injury site with myeloid bias being observed in the initial inflammation and the lymphoid in the late-resolution phases of the pathology. Multiple evidence demonstrates that aging enhances damage to various cellular processes through inflamm-aging, an inflammatory process identified to increase pro-inflammatory markers in circulation and tissues. Following MI, marked changes were observed in different sub-sets of major myeloid cell types viz., neutrophils, monocytes, and macrophages. There is a paucity of information regarding the tissue and site-specific functions of these sub-sets. In this review, we highlight the importance of age and sex as crucial risk factors by discussing their role during MI-induced myelopoiesis while emphasizing the current status of myeloid cell sub-sets. We further put forth the need for designing and executing age and sex interaction studies aimed to determine the appropriate age and sex to develop personalized therapeutic strategies post-MI.

Abstract
OBJECTIVE Aging male syndrome is a clinical biochemical syndrome characterized by typical aging symptoms and serum testosterone deficiency. Although it is accompanied by various health problems, directly affects life satisfaction, and requires proper management, no clear prevention or treatment other than hormone replacement therapy is currently available for this syndrome. Here, we aimed to determine the efficacy and safety of the Lespedeza cuneata extract in the management of the aging male syndrome. METHODS Males aged 43-70 years who provided consent for participation and had a total Aging Males' Symptom questionnaire score ≥ 37 and testosterone level ≤ 500 ng/dL were enrolled in this study. This study was conducted in a randomized, double-blind manner. Participants were randomly assigned to either the experimental or control groups and orally administered the assigned product twice a day. Efficacy was evaluated by measuring changes in Aging Males' Symptom score, Androgen Deficiency in the Aging Male questionnaire score, International Index of Erectile Function score, International Prostatic Symptom Score, blood test results, and body mass index at 8 weeks. RESULTS After 8 weeks, the experimental group had significantly improved symptom scores compared to the control group on the Aging Males' Symptom and Androgen Deficiency in the Aging Male questionnaires. However, no significant differences in the International Index of Erectile Function score, International Prostatic Symptom Score score, blood test results, and body mass index were observed between the experimental and control groups. CONCLUSION Lespedeza cuneata extract safely alleviates andropause symptoms without any significant side effects, suggesting its potential for the treatment of the aging male syndrome.

Abstract
The primary objectives of this study were to assess the inhibitory effects of Allium ampeloprasum L. extract (AAE) and its derived organosulfur and polyphenolic compounds on the enzymatic activities of cGMP-specific PDE V (PDE5) and aminopeptidase N (APN). Additionally, the study aimed to investigate their potential as inhibitors against these two target enzymes through kinetic analyses and molecular docking studies. The in vitro enzyme assays demonstrated that both AAE and its derived compounds significantly decreased the activity of PDE5 and APN. Further analyses involving kinetics and molecular docking provided insights into the specific inhibitor types of AAE and its derived compounds along with the proposed molecular docking models illustrating the interactions between the ligands (the compounds) and the enzymes (PDE5 and APN). In particular, AAE-derived polyphenolic compounds showed relatively stable binding affinity (-7.2 to -8.3 kcal/mol) on PDE5 and APN. Our findings proved the potential as an inhibitor against PDE5 and APN of AAE and AAE-derived organosulfur and polyphenolic compounds as well as a functional material for erectile dysfunction improvement.

Abstract
BACKGROUND AND AIMS This study aimed to explore the proportion of andropause in male patients with type 2 diabetes using an aging male symptoms scale and assess the clinical outcome of testosterone supplementation in patients with deficient testosterone levels at a tertiary care hospital. METHODS Male patients with diabetes and total serum testosterone levels (≤12 nmol/L) were included in the study. Patients with testosterone supplementation, the standard of care among testosterone-deficient male patients, were included in the study (n = 35). Those not exposed to testosterone supplementation were considered controls (n = 35) and reassessed over 14 weeks for aging male symptom scores (AMS). RESULTS The prevalence of andropause among the participants was 11% (117/1057). Data was analyzed as per protocol analysis. Exposure group had a frequency of 25.80%, and 19.35% in moderate and severe symptoms of AMS scores. Non-exposure group had frequency of 26.66% and 23.34% in moderate and severe symptoms of AMS scores. A significant mean difference (t = -2.93, P-value <0.05) was noted between exposure and non-exposure to testosterone supplementation. CONCLUSION Results concluded that andropause is prevalent in patients with type 2 diabetes and low testosterone levels. Testosterone therapy affects aging andropausal symptoms such as the feeling of general well-being, joint pain and muscular ache, sleep problems, anxiety, and libido among patients with type 2 diabetes.

Abstract
Several studies have reported the effects of the consumption of various mushroom species on the testes in animal experimental models. Mushrooms, including enokitake mushrooms (Flammulina velutipes), and vegetables contain adenosine may affect testosterone production. Here, we aimed to elucidate the effects of enokitake and its active component, adenosine, on testosterone production in primary cultures of testicular cells in vivo using mice models and in vitro. The administration of enokitake ethanolic extract increased testosterone production in the cisplatin-impaired mouse model. The direct effect of mushroom extracts on testicular cells was examined and liquid chromatography-mass spectrometry analysis confirmed that the mushroom- and vegetable-induced increase in testosterone production mainly involved adenosine. Additionally, the administration of enokitake extract or adenosine to wet floor fatigue model mice promoted testicular testosterone production and enhanced Leydig cell function through insulin-like peptide three level upregulation. Structurally related compounds, including cordycepin, showed lower bioactivity than adenosine. This study showed that the ingestion of adenosine-containing mushrooms and vegetables may effectively increase testicular testosterone production. We conclude that mushrooms with a relatively high adenosine content, such as enokitake, may be useful against aging and fatigue.

Abstract
Biological sex contributes to phenotypic sex effects through genetic (sex chromosomal) and hormonal (gonadal) mechanisms. There are profound sex differences in the prevalence and progression of age-related brain diseases, including neurodegenerative diseases. Inflammation of neural tissue is one of the most consistent age-related phenotypes seen with healthy aging and disease. The pro-inflammatory environment of the aging brain has primarily been attributed to microglial reactivity and adoption of heterogeneous reactive states dependent upon intrinsic (i.e., sex) and extrinsic (i.e., age, disease state) factors. Here, we review sex effects in microglia across the lifespan, explore potential genetic and hormonal molecular mechanisms of microglial sex effects, and discuss currently available models and methods to study sex effects in the aging brain. Despite recent attention to this area, significant further research is needed to mechanistically understand the regulation of microglial sex effects across the lifespan, which may open new avenues for sex informed prevention and treatment strategies.

Abstract
Objective This study was planned to examine the validity and reliability of the Turkish version of the Male Andropause Symptoms Self-Assessment Questionnaire (MASS-Q). Materials and Methods One hundred and twenty-five men with a mean age of 54.24 ± 6.51 years participated in the study. First, participants' demographic data were recorded. Then, the MASS-Q was adapted to Turkish. The assess the reliability and validity of the Turkish MASS-Q, internal consistency, test-retest reliability, and criterion validity analyses were administered. For the reliability test, the scale was readministered 1 week later. Test-retest reliability was examined with the intraclass correlation coefficients (ICCs). Internal consistency was defined by Cronbach's alpha. Regarding the validity analysis, content validity was determined according to expert opinions. For criterion validity, the Aging Male Symptoms-Questionnaire (AMS-Q) was used. Results According to the results of the analysis, the ICC values between the test-retest scores of the total and subdimensions (sexual, somatic, psychic, and behavior) of the MASS-Q were found to be 0.987, 0.939, 0.973, 0.951, and 0.887, respectively (P < 0.05). Cronbach's alpha values of the total and subdimensions (sexual, somatic, psychic, and behavior) of the MASS-Q were calculated as 0.924, 0.870, 0.747, 0.865, and 0.667, respectively. According to the ICC values obtained, it was found that the MASS-Q had a high degree of reliability. According to the internal consistency results, the sexual and psychic subdimensions were found to be quite reliable, whereas the somatic and behavioral subdimensions were found to be sufficiently reliable. According to the criterion validity results, a very high and high correlations were found between the AMS-Q scores and the MASS-Q scores (r = 0.636-0.938, P = 0.001). Conclusion As a result, it was determined that the Turkish version of the MASS-Q is a valid and reliable scale that can be used in Turkish men.

Int J Mol Sci 2022; 23:ijms232012689.

Abstract
We report herein a novel mechanism, unraveled by proteomics and validated by in vitro and in vivo studies, of the aberrant aging-associated upregulation of ovarian transferrin and ferritin in rat ovaries. The ovarian mass and serum estradiol titer plummeted while the ovarian labile ferrous iron and total iron levels escalated with age in rats. Oxidative stress markers, such as nitrite/nitrate, 3-nitrotyrosine, and 4-hydroxy-2-nonenal, accumulated in the aging ovaries due to an aberrant upregulation of the ovarian transferrin, ferritin light/heavy chains, and iron regulatory protein 2(IRP2)-mediated transferrin receptor 1 (TfR1). Ferritin inhibited estradiol biosynthesis in ovarian granulosa cells in vitro via the upregulation of a nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and p65/p50-induced oxidative and inflammatory factor inducible nitric oxide synthase (iNOS). An in vivo study demonstrated how the age-associated activation of NF-κB induced the upregulation of iNOS and the tumor necrosis factor α (TNFα). The downregulation of the keap1-mediated nuclear factor erythroid 2-related factor 2 (Nrf2), that induced a decrease in glutathione peroxidase 4 (GPX4), was observed. The aberrant transferrin and ferritin upregulation triggered an iron accumulation via the upregulation of an IRP2-induced TfR1. This culminates in NF-κB-iNOS-mediated ovarian oxi-inflamm-aging and serum estradiol decrement in naturally aging rats. The iron accumulation and the effect on ferroptosis-related proteins including the GPX4, TfR1, Nrf2, Keap1, and ferritin heavy chain, as in testicular ferroptosis, indicated the triggering of ferroptosis. In young rats, an intraovarian injection of an adenovirus, which expressed iron regulatory proteins, upregulated the ovarian NF-κB/iNOS and downregulated the GPX4. These novel findings have contributed to a prompt translational research on the ovarian aging-associated iron metabolism and aging-associated ovarian diseases.

Abstract
The effects of androgens have been extensively studied in a variety of organs and cell types with increasing focus on the sexually dimorphic role androgens play not only with respect to cellular functions but also in metabolism. Although the classical mechanism of androgen action is via ligand-dependent binding with the nuclear transcription factor, androgen receptor (AR), cytosolic AR can also activate second messenger signaling pathways. Given that cytosolic AR can signal in this manner, there has been increased interest in the mechanisms by which androgens may control cellular organelle function. This review highlights the effects that androgens have on mitochondrial structure and function with emphasis on biogenesis, fusion/fission, mitophagy, bioenergetics (oxidative phosphorylation), and reactive oxygen species production. There are a number of publications on the effects of androgens in these general areas of mitochondrial function. However, the precise mechanisms by which androgens cause these effects are not known. Additionally, given that the nucleus and mitochondria work in tandem to control mitochondrial function and the mitochondria has its own DNA, future research efforts should focus on the direct, mechanistic effects of androgens on mitochondrial function.

Abstract
OBJECTIVE We aimed to investigate the role of testosterone to estradiol ratio in predicting the effectiveness of human chorionic gonadotropin and testosterone treatments in male hypogonadism. METHODS Thirty-six male patients with hypogonadotropic hypogonadism were included in the study. Seventeen (47.2%) patients received weekly recombinant human choriogonadotropin alpha (hCG) treatment (group-1) and 19 (52.8%) received testosterone replacement therapy (T treatment) every 21 days (group-2). Under these treatments, adequate frequency of morning erection (≥3/week), testosterone to estradiol ratio (T/E), and testicular volume changes were analyzed. RESULTS The mean age of the patients was 28.5 ± 8.7 years. When the frequency of morning erection (≥3/week) was specified as adequate, the cut-off value for effective T/E ratio was found to be 12.0 (sensitivity 93.8%, specificity 90.0%). There was no significant difference between the treatment groups in terms of total testosterone levels, T/E ratio, or frequency of morning erections (≥3/week) (p > 0.05). However, there was a statistically significant difference between the groups in terms of median left-right testicular volume in favor of group-1 (p < 0,05). CONCLUSION In patients with hypogonadism who are under treatment, elevated estradiol-induced erectile dysfunction symptoms may persist even if serum testosterone levels are normal. Testosterone to estradiol ratio can be used as a predictive value in the effective treatment of hypogonadotropic hypogonadism with hCG and T.

Abstract
Objective Morbid obesity may be related to a prolactinoma, although uncommon, and can lead to adverse effects like insulin resistance and metabolic syndrome. Recent research suggests that hyperprolactinemia causes an abnormal lipid profile, weight gain, and cardiovascular diseases. Moreover, high prolactin levels lead to decreased testosterone production by disrupting 17-b-estradiol synthesis. Our objective was to present a case of prolactinoma with morbid obesity, hypogonadism, and then significant weight loss after dopamine agonist treatment. Methods The clinical course, in addition to serial laboratory and imaging results, are presented. These include prolactin levels, testosterone levels, thyroid function tests, blood sugar levels, and serial lipid profiles. Results In this report, we discuss a case of 30-year-old male with prolactin-secreting macroadenoma with clinical features of hypogonadism, hypothyroidism, and morbid obesity. He showed marked improvement in obesity and hypogonadism with dopamine agonist therapy supplemented with clomiphene citrate. Conclusion Prolactinomas with morbid obesity can be successfully treated contingent upon proper medication and compliance with medications. Insulin resistance, hypogonadism, prolactin levels, body mass index, and tumor size all improved by regular follow-up and treatment adherence.

Abstract
Aging is a complex biological process characterized by hallmark features accumulating over the life course, shaping the individual's aging trajectory and subsequent disease risks. There is substantial individual variability in the aging process between men and women. In general, women live longer than men, consistent with lower biological ages as assessed by molecular biomarkers, but there is a paradox. Women are frailer and have worse health at the end of life, while men still perform better in physical function examinations. Moreover, many age-related diseases show sex-specific patterns. In this review, we aim to summarize the current knowledge on sexual dimorphism in human studies, with support from animal research, on biological aging and illnesses. We also attempt to place it in the context of the theories of aging, as well as discuss the explanations for the sex differences, for example, the sex-chromosome linked mechanisms and hormonally driven differences.

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.

METHODS This cross-sectional study was conducted on 80 male employees aged 40-60 years, with hypogonadism, at TUMS. The participants were selected through census sampling. The data collection tools included the demographic questionnaire and the Aging Male Symptoms (AMS) questionnaire. The participants first completed the demographic questionnaire and then the AMS questionnaire. SPSS statistical software version 22 (Chicago, IL) was used to analyze the data, and one-way ANOVA tests, Pearson's correlation coefficient, and stepwise multivariate logistic regression were applied. RESULTS Based on our findings, the mean overall score of hypogonadism symptoms was 41.71 ± 9.20. Based on Pearson's correlation coefficient results, there was a statistically significant association between the severity of hypogonadism symptoms and age (p < .001). Furthermore, there were significant associations between the economic status, cigarette consumption and hours of sleep and the severity of hypogonadism symptoms (p < .001). CONCLUSIONS The current study's results showed that certain factors can affect hypogonadism in males. Thus, it is important to reduce the severity of hypogonadism symptoms and to modify the factors related to this phenomenon.

Abstract
Introduction and objective: With the world's older population continuing to grow, andropause (male menopause or late-onset hypogonadism) is considered as one of the most important issues of this era. In this study, we aimed to assess the effect of andropause health education on the level of knowledge and attitude of retired men.Methods: This controlled trial was conducted on 80 retired men (40 in intervention group, 40 in control group), who had been employed by the Department of Education, Shiraz, Iran. Data collection tool was a 38-item questionnaire, designed by the researcher, on participants' knowledge and attitude about andropause. Data were analyzed using SPSS software, version 22 and statistical tests such as independent and paired t tests were used.Findings: There was no significant difference between the intervention and control groups before the intervention. There was a significant difference in knowledge and attitude scores in each group immediately and 1 month after the intervention. The mean score of knowledge in the intervention group increased from 2.92 ± 1.68 before to 16.22 ± 1.34 after the intervention, and the attitude score increased from 14.9 ± 1.08 to 28.52 ± 1.44. Comparison of the two groups and repeated score analysis showed that there was a significant difference between the two groups over the time (p < .001).Conclusion: Educational intervention improved the knowledge and attitude of retired men toward andropause, which can have a positive impact on the timely recognition and proper treatment of the complications of andropause.

Abstract
Abstract
Andropause, the culminating phase of male ageing, is characterized by deregulation of the hypothalamic-pituitarygonadal axis and low circulating free testosterone. The aim of this study was to investigate the immunohistomorphometric characteristics of the pituitary gonadotropic i.e. follicle-stimulating hormone (FSH) and the luteinizing hormone (LH) producing cells after testosterone application in a rat model of the andropause. Middle-aged Wistar rats were divided into orchidectomized (ORX; n=8) and testosterone treated orchidectomized (ORX+T; n=8) groups. Testosterone propionate (5 mg/kg b.m./day) was administered for three weeks, while the ORX group received the vehicle alone. Immunohistochemically stained FSH and LH cells underwent morphometric and optical density-related analysis, while circulating concentrations of the sex steroids were measured by immunoassays. Serum concentrations of testosterone and estradiol were significantly (p<0.05) increased by 24 and 2.7 fold respectively, compared to the ORX group. The volume of FSH and LH cells was significantly (p<0.05) decreased by 51.3% and 56.6% respectively, in comparison with ORX rats. Relative volume density of FSH and LH cells was also significantly (p<0.05) decreased by 54.0% and 72.8% respectively, compared to the ORX group. Results related to the optical density of gonadotropic cells (reflecting their hormonal content) were in line with the morphometric findings i.e. this parameter of FSH and LH cells was significantly (p<0.05) decreased by 25.7% and 16.2% respectively, in comparison with ORX rats. Conclusion: In conclusion, applied testosterone increased the serum concentrations of sex steroids, as well as it decreased morphometric parameters and optical density of gonadotropic cells in ORX rats.

Findings from the Men's Health 40+ Study. Andrology 2018; 6:896-902. [PMID: 29993200 PMCID: PMC6585816 DOI: 10.1111/andr.12516] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2017] [Revised: 04/29/2018] [Accepted: 05/26/2018] [Indexed: 11/29/2022]
Abstract
In males, age‐related decline in free testosterone (T) and dehydroepiandrosterone (DHEA) by 2–3% per year has been reported. Estradiol (E2) and progesterone (P) seem to decrease as well, but to a lesser extent. Lower sex steroid levels in men have been related to physical and mental symptoms. Low birthweight and left‐/mixed‐handedness (L/MH) are indicators of an adverse fetal environment during pregnancy, and both have been linked to morbidity in later life. The aim of this study is to examine the relationship between lower birthweight as well as L/MH and age‐related sex steroid decline. In a cross‐sectional study design, saliva samples were collected under standardized conditions from healthy men for subsequent steroid hormone analysis using standard luminescence immunoassays. T (M = 67.57 pg/mL), DHEA (M = 247.91 pg/mL), E2 (M = 1.29 pg/mL), and P (M = 28.20 pg/mL) have been quantified leading to a final sample of 256 men providing complete data on sex hormones (MAge=57.8; SDAge = 10.8). Information on participants’ birthweight was obtained from birth reports (N = 134), and participants were asked about their handedness (right‐handed, left‐handed, mixed‐handed) (N = 256). Multivariate‐adjusted linear regression models relating each sex hormone individually and the principal component of declining steroid hormones (DSH)—an integrated hormonal parameter—with handedness and birthweight did not identify significant associations except for handedness and E2. Moderation analysis using robust regression accounting for bias due to influential data points detected a significant association between age and DSH for handedness (β = −0.0314, p = 0.040) but only a trend for birthweight (β = 0.0309, p = 0.073). For lower birthweight, a trend toward intensified age‐related sex steroid decline in men was observed, while for L/MH, a significant association with intensified age‐related sex steroid decline was identified. These results indicate that L/MH and potentially also lower birthweight might be considered as early risk factors for endocrine health in later life.

Abstract
The pathological phenomenon of somatopause, noticeable in hypogonadal ageing subjects, is based on the growth hormone (GH) production and secretion decrease along with the fall in GH binding protein and insulin-like growth factor 1 (IGF-1) levels, causing different musculoskeletal, metabolic and mental issues. From the perspective of safety and efficacy, GH treatment is considered to be highly controversial, while some other therapeutic approaches (application of IGF-1, GH secretagogues, gonadal steroids, cholinesterase-inhibitors or various combinations) exhibit more or less pronounced weaknesses in this respect. Soy isoflavones, phytochemicals that have already demonstrated the health benefits in treated elderly, at least experimentally reveal their potential for the somatopausal symptoms remediation. Namely, genistein enhanced GHRH-stimulated cAMP accumulation and GH release in rat anterior pituitary cells; refreshed and stimulated the somatotropic system (hypothalamic nuclei and pituitary GH cells) function in a rat model of the mild andropause, and stimulated the GH output in ovariectomized ewes as well as the amplitude of GH pulses in the rams. Daidzein, on the other hand, increased body mass, trabecular bone mass and decreased bone turnover in the animal model of severe andropause, while both isoflavones demonstrated blood cholesterol-lowering effect in the same model. These data, which necessarily need to be preclinically and clinically filtered, hint some cautious optimism and call for further innovative designing of balanced soy isoflavone-based therapeutics.

Abstract
Research on healthy aging in men has increasingly focused on age-related hormonal changes. Testosterone (T) decline is primarily investigated, while age-related changes in other sex steroids (dehydroepiandrosterone [DHEA], estradiol [E2], progesterone [P]) are mostly neglected. An integrated hormone parameter reflecting aging processes in men has yet to be identified. 271 self-reporting healthy men between 40 and 75 provided both psychometric data and saliva samples for hormone analysis. Correlation analysis between age and sex steroids revealed negative associations for the four sex steroids (T, DHEA, E2, and P). Principal component analysis including ten salivary analytes identified a principal component mainly unifying the variance of the four sex steroid hormones. Subsequent principal component analysis including the four sex steroids extracted the principal component of declining steroid hormones (DSH). Moderation analysis of the association between age and DSH revealed significant moderation effects for psychosocial factors such as depression, chronic stress and perceived general health. In conclusion, these results provide further evidence that sex steroids decline in aging men and that the integrated hormone parameter DSH and its rate of change can be used as biomarkers for healthy aging in men. Furthermore, the negative association of age and DSH is moderated by psychosocial factors.

Abstract
INTRODUCTION Andropause is a gradual process and more similar to menopause in women. Knowledge and experience of symptoms of andropause is an important discussion is in their lives. OBJECTIVES This study aimed to determine Awareness and Experience of Andropause Symptoms in Men referring to Health Centers in Rasht, Iran. MATERIALS AND METHODS This cross-sectional and analytical study included 140 men over 40 years referring to one of health centers. Collection tool of this study was a questionnaire consisting of three parts. The first part was about demographic characteristics, The second part was a researcher-made questionnaire, The third part was Aging Male Scales (AMS) questionnaire. Data were analyzed by descriptive and analytical statistics. RESULTS This study showed 73.6% had experience symptoms of andropause. The mean knowledge score (of 20 score) for the 3/3 ± 4/9, with the level of education, occupation and income was statistically significant (p < 0.05). There was significant relationship the andropause symptoms with BMI and occupation (p < 0.05). CONCLUSION Based on the results of this study, despite the fact that the majority of men over age 40 had experienced symptoms of andropause, but their awareness about andropause was very low.

Abstract
Male ageing is entwined with a continuous fall in free testosterone levels, which contributes to the pathogenesis of bone loss. Glucocorticoid excess, either dependent on the ageing process or iatrogenically induced, was found to additionally impair the bone structure and metabolism. Cautious testosterone supplementation in this respect may positively affect the glucocorticoid milieu and bone homeostasis, while testosterone-induced changes in the glucocorticoid output could serve as a determinant of bone-related therapeutic outcome. Namely, bone mineral content/density, the parameters of trabecular bone structure as well as bone strength are enhanced, serum calcitonin levels tend to increase, while serum osteocalcin, serum parathyroid hormone and urinary calcium decrease, all upon testosterone administration to the ageing male. In parallel, testosterone application decreases glucocorticoid secretion in the animal models of male ageing, while clinical data in this field are still inconsistent. Importantly, a physiological link exists between testosterone-induced changes in glucocorticoid levels and the tendency of bone status improvement in the ageing male. We believe that the assessment of circulating adrenocorticotropic hormone concentrations together with glucocorticoid levels, reflecting the hypothalamic-pituitary-adrenal axis feedback loop operativeness during testosterone supplementation, represents a well-balanced bone-related therapeutic update.

Bcl-2 expression is a poor predictor for hepatocellular carcinoma prognosis of andropause-age patients. Cancer Biol Med 2016; 13:459-468.

Abstract
OBJECTIVE The expression of B-cell lymphoma 2 (Bcl-2) seems to be influenced by the endocrine environment. Numerous reports demonstrate the diverse expression of Bcl-2 family members under sex steroid regulation. With the exception of estrogen-related tumors, androgen-related tumors have shown their characteristics in Bcl-2 expression. In this study, the status of Bcl-2 expression in male hepatocellular carcinoma (HCC) patients was examined to verify the high incidence of HCC in males. METHODS Tumor tissue microarray was used to examine Bcl-2 expression levels in 374 HCC cases including 306 males and 68 females. Kaplan-Meier method, log-rank test, and Cox proportional hazards model were applied to investigate the predictive value of Bcl-2 in HCC patients. RESULTS Immunohistochemistry analysis showed that male patients with higher Bcl-2 levels had significantly longer median survival time and recurrence time than those with lower levels. However, no significant differences in outcomes were found between different Bcl-2 levels in female patients. When the male patients were stratified into several age points, the level of Bcl-2 expression showed poorer predictive efficiency in the 45-49 and 55-60 age groups in andropause-age patients compared with other age groups. Bcl-2 was an independent prognostic factor for both overall survival (P < 0.0001) and recurrence time (P = 0.0001) in male patients. After excluding male patients in the 45-60 age group, the predictive efficiency was enhanced (n = 147, OS, P = 0.0002, TTR, P < 0.0001). CONCLUSIONS Bcl-2 expression is an independent predictor of survival and recurrence in male HCC. Bcl-2 levels may also be regulated by androgens or androgen receptors in male HCC patients. Bcl-2 levels change and exhibit poor predictive efficiency when androgen levels vary dramatically (andropause age).

Abstract
This study examined the effect of Testofen, a specialised Trigonella foenum-graecum seed extract on the symptoms of possible androgen deficiency, sexual function and serum androgen concentrations in healthy aging males. This was a double-blind, randomised, placebo-controlled trial involving 120 healthy men aged between 43 and 70 years of age. The active treatment was standardised Trigonella foenum-graecum seed extract at a dose of 600 mg/day for 12 weeks. The primary outcome measure was the change in the Aging Male Symptom questionnaire (AMS), a measure of possible androgen deficiency symptoms; secondary outcome measures were sexual function and serum testosterone. There was a significant decrease in AMS score over time and between the active and placebo groups. Sexual function improved, including number of morning erections and frequency of sexual activity. Both total serum testosterone and free testosterone increased compared to placebo after 12 weeks of active treatment. Trigonella foenum-graecum seed extract is a safe and effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged and older men.

Abstract
Late-onset hypogonadism is an underdiagnosed and easily treated condition defined by low serum testosterone levels in men older than 65 years. When treated, a significant improvement in quality of life may be reached in this rapidly rising sector of the population. During the evaluation, laboratory tests and a full medication review should be performed to exclude other illnesses or adverse effects from medications. The major goal of treatment in this population is treating the symptoms related to hypogonadism. There has not been clear evidence supporting universally giving older men with low serum testosterone levels and hypogonadal symptoms testosterone replacement therapy.

Abstract
BACKGROUND Kallmann syndrome (KS) is a rare genetic condition characterized by congenital early-onset hypogonadotropic hypogonadism and anosmia or hyposmia. Male subjects are more frequently affected and present absent/delayed puberty, low testosterone levels with higher risk for osteoporosis. Therefore, to maintain normal levels of sex steroids and prevent bone loss, male KS needs life-long hormonal replacement therapy (HRT). AIMS The objective of our study is to assess bone involvement in subjects with KS currently treated with HRT. METHODS In our retrospective study, we analyzed data from medical records of patients with KS treated with HRT (either gonadotropins or testosterone preparations), including clinical history, biochemical parameters, and the following outcome measures: the bone mineral density (BMD) at the lumbar spine (LS), femoral neck (FN), and total body less head (TBLH); and the Vertebral Fracture Assessment (VFA) by Dual Energy X-ray Absorptiometry (DXA). RESULTS Clinical and instrumental data of 32 patients with KS were evaluated; their mean age was 30.32 (± 10.09) years, their mean body mass index (BMI) was 25.71 (± 3.23) kg/m(2). Four patients (12.5%) had a LS BMD Z score below the expected range for age. Five patients had vertebral deformities observed at VFA. Duration of HRT was related to bone health parameters: BMD at all measured sites were higher in patients receiving adequate HRT for more than 2 years compared with the patients treated for less than 6 months. A deficient vitamin D status was found in 43% of cases and it was prevalent in patients with shorter HRT. DISCUSSION AND CONCLUSION Early starting and adequate duration of HRT are related to bone health parameters in patients with congenital hypogonadotropic hypogonadism due to KS. Restoring vitamin D sufficiency might also be advisable in this condition.

Abstract
The term ‘male menopause’ was first used in 1944 to describe various complaints of ageing men which at least partially mirrored the climacteric symptoms in women. Continuous research resulted in the evolution of opinions about the nature of these complaints, from the clinical syndrome, diagnosed with the use of disease-targeted questionnaires, to a well-defined clinical and biochemical syndrome. The pathophysiological causes – gonad ageing (with a compensatory rise in luteinizing hormone), age-related increase in serum sex hormone-binding globulin (SHBG) levels, the role of visceral adipose tissue as a place for aromatization of androgen to estrogen, and lower sensitivity of testosterone receptors – have been described. However, no consensus was reached as far as the definition, incidence, treatment, and especially testosterone therapy, are concerned. Our review presents the current standpoints, indicating the predictive role of late-onset hypogonadism (LOH) in evaluating male health as well as the current literature reports on the risks and benefits of using testosterone therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paffia spp (Amaranthacea) has a widespread use of in Brazil as a possible hormonal supplement and a substitute of Panax ginseng, although information on its reproductive effects is missing. AIM OF THE STUDY To evaluated possible anabolic-androgenic or anti-androgenic effects of Pfaffia glomerata (PG) extract using intact eight-months-old male rats and pre-pubertal castrated rats. MATERIALS AND METHODS Three different dose levels of PG (8.5, 30 and 85 mg/kg/day) were administered to eight-months-old rats for 28 days or to castrated males for 7 days (Hershberger assay). In the experiment with intact animals, 24h fecal samples were collected for quantification of fecal metabolites of androgens throughout treatment. At the end of the treatment period, animals were euthanized for evaluation of serum testosterone, reproductive organ weights, number of spermatids per testis, diameter of seminiferous tubules and cross-sectional area of soleus muscle fibers. In the Hershberber assay, androgenic or anti-androgenic effects were evaluated by the weights of androgen-dependent tissues: ventral prostate, seminal vesicle, glans penis and levator ani muscle/bulbocavernosus muscle. RESULTS No effects were observed in the concentrations of fecal metabolites of androgens monitored during the treatment of intact eight-months-old rats. Moreover, at the end of treatment, no changes were seen in any of the investigated parameters. In the Hershberger assay, the PG extract did not induce androgenic or anti-androgenic effects at the dose levels tested. Significant effects were only observed in animals treated with testosterone and testosterone plus flutamide, which were used as positive controls for androgenicity and anti-androgenicity, respectively. CONCLUSIONS At the dose levels tested, PG extract does not induce anabolic-androgenic or anti-androgenic effects in rats.
