Abstract
Use of anabolic androgenic steroids (AAS) causes drastic changes in hormonal milieu and is associated with a range of medical and psychological consequences. Sleep pathology is a common side-effect of AAS use but few have studied these relations. This study examined the relationship between AAS use, psychological distress and sleep quality, and how phases of heavy use and abstinence influence sleep. The Pittsburgh-Sleep-Quality-Index (PSQI) and Jenkins Sleep Scale (JSS) were used to assess sleep quality, and psychological distress was measured with the Hopkins Symptoms Checklist (HSCL). Participants comprised men who have previous or current long-term use of AAS (n = 68) and non-using weightlifting controls (WLC) (n = 58), where a subgroup of participants (n = 22) was monitored over ~ 6 months during phases of AAS use and withdrawal. Group differences on PSQI and JSS were evaluated with Kruskal-Wallis H tests, and the mediating role of psychological distress was evaluated using structural equation modeling. Linear mixed models were used to assess the role of AAS use and withdrawal on sleep quality. Among the AAS group, 66% reported sleep problems as a side effect, and 38% had used sleep medication. PSQI scores showed significantly lower sleep quality in the AAS group compared to WLC (p < 0.001) on all subscales except "sleep latency". Furthermore, sleep quality was significantly poorer during withdrawal-phases than periods with AAS use (p < .001). Our findings provide key insight into sleep disturbances among men who use AAS, suggesting a link between sleep disturbances and hormone levels that deviate from physiologically normal levels in both directions.

Sleep 2023; 46:zsad249. [PMID: 37715990 PMCID: PMC10636253 DOI: 10.1093/sleep/zsad249] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/05/2023] [Indexed: 09/18/2023] Open
Abstract
STUDY OBJECTIVES Sex differences in sleep architecture are well-documented, with females experiencing longer total sleep time, more slow wave sleep (SWS), and shorter Rapid Eye Movement (REM) sleep duration than males. Although studies imply that sex hormones could affect sleep, research on exogenous sex hormones on sleep architecture is still inconclusive. This study examined sleep architecture changes in transgender individuals after 3 months of gender-affirming hormone therapy (GAHT). METHODS We assessed sleep architecture in 73 transgender individuals: 38 transmasculine participants who started using testosterone and 35 transfeminine participants who started using estrogens and antiandrogens. Sleep architecture was measured before GAHT and after 3 months of GAHT for 7 nights using an ambulatory single-electrode sleep EEG device. Changes in sleep architecture were analyzed using linear mixed models, and non-normally distributed outcomes were log-transformed and reported as percentages. RESULTS In transmasculine participants, SWS decreased by 7 minutes (95% CI: -12; -3) and 1.7% (95% CI: -3%; -0.5%), REM sleep latency decreased by 39% (95% CI: -52%; -22%) and REM sleep duration increased by 17 minutes (95% CI: 7; 26) after 3 months of GAHT. In transfeminine participants, sleep architecture showed no significant changes after 3 months of GAHT. CONCLUSIONS Sleep architecture changes after 3 months of masculinizing GAHT in line with sleep in cisgender males, while it shows no changes after feminizing GAHT. The sex-specific nature of these changes raises new questions about sex hormones and sleep. Future research should focus on studying possible underlying neural mechanisms and clinical consequences of these changes.

Graziani A, Grande G, Ferlin A. The complex relation between obstructive sleep apnoea syndrome, hypogonadism and testosterone replacement therapy. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1219239. [PMID: 37881222 PMCID: PMC10597633 DOI: 10.3389/frph.2023.1219239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 08/22/2023] [Indexed: 10/27/2023] Open
Abstract
Obstructive sleep apnoea syndrome (OSAS) is an under-recognized medical disease. The main risk factors for OSAS are male sex, older age, obesity, and metabolic syndrome, that are also associated with male hypogonadism (MH). Therefore, obesity has been classically identified as the most evident link between OSAS and MH. However, OSAS is per se linked to the development of MH by a combined effect of hypoxia, increased night-time awakenings, reduced sleep efficiency and fragmented sleep. Similarly, MH might represent a risk factor for OSAS, mainly related to sleep disturbances that are frequently associated with low testosterone. Data on testosterone replacement therapy (TRT) in patients with OSAS are limited. Nevertheless, TRT is generally contraindicated by guidelines in the presence of untreated or severe OSAS. TRT might in fact worse OSAS symptoms in different ways. Furthermore, OSAS has been proposed to be a risk factor for secondary polycythaemia and TRT might exacerbate polycythaemia. Therefore, TRT in hypogonadal men affected by untreated OSAS or severe OSAS should be considered with caution and in a personalised way. Nevertheless, the type and dosage of TRT should be considered, as short-term high-dose TRT might worsen OSAS, whereas long-term lower doses could eventually determine a clinical improvement of symptoms of OSAS. Here we reviewed the data on the association between OSAS, MH and TRT, including the opportunity of assessment of patients who develop signs and symptoms of OSAS during TRT by polysomnography.

Abstract
STUDY OBJECTIVES Transgender persons can use gender-affirming hormone therapy (GAHT) to align their physical appearance with their identified gender. Many transgender persons report poor sleep, but the effects of GAHT on sleep are unknown. This study examined the effects of a 12 months of GAHT use on self-reported sleep quality and insomnia severity. METHODS A sample of 262 transgender men (assigned female at birth, started masculinizing hormone use) and 183 transgender women (assigned male at birth, started feminizing hormone use), completed self-report questionnaires on insomnia (range 0-28), sleep quality (range 0-21) and sleep onset latency, total sleep time and sleep efficiency before start of GAHT and after 3, 6, 9, and 12 months of GAHT. RESULTS Reported sleep quality showed no clinically significant changes after GAHT. Insomnia showed significant but small decreases after 3 and 9 months of GAHT in trans men (-1.11; 95%CI: -1.82; -0.40 and -0.97; 95%CI: -1.81; -0.13, respectively) but no changes in trans women. In trans men, reported sleep efficiency decreased by 2.8% (95%CI: -5.5%; -0.2%) after 12 months of GAHT. In trans women, reported sleep onset latency decreased by 9 min (95%CI: -15; -3) after 12 months of GAHT. CONCLUSIONS These findings show that 12 months of GAHT use did not result in clinically significant changes in insomnia or sleep quality. Reported sleep onset latency and reported sleep efficiency showed small to modest changes after 12 months of GAHT. Further studies should focus on underlying mechanisms by which GAHT could affect sleep quality.

Abstract
PURPOSE To provide the evidence-based recommendations on the role of testosterone (T) on age-related symptoms and signs remains. METHODS The Italian Society of Andrology and Sexual Medicine (SIAMS) and the and the Italian Society of Endocrinology (SIE) commissioned an expert task force to provide an updated guideline on adult-onset male hypogonadism. Derived recommendations were based on Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. RESULTS Clinical diagnosis of adult-onset hypogonadism should be based on a combination of clinical and biochemical parameters. Testosterone replacement therapy (TRT) should be offered to all symptomatic subjects with hypogonadism after the exclusion of possible contraindications. T gels and the long-acting injectable T are currently available preparations showing the best efficacy/safety profile. TRT can improve all aspects of sexual function, although its effect is limited in more complicated patients. Body composition (reducing fat mass and increasing lean mass) is improved after TRT, either in subjects with or without metabolic syndrome or type 2 diabetes. Conversely, the role of TRT in improving glycometabolic control is more conflicting. TRT can result in increasing bone mineral density, particularly at lumbar site, but no information on fracture risk is available. Limited data support the use of TRT for improving other outcomes, including mood frailty and mobility. CONCLUSIONS TRT can improve sexual function and body composition particularly in less complicated adult and in aging subjects with hypogonadism. When hypogonadism is adequately diagnosed, T appropriately prescribed and subjects correctly followed up, no short-term increased risk of adverse events is observed. Longer and larger studies are advisable to better clarify TRT long-term efficacy/safety profile.

Abstract
Hypogonadism has been associated with significant deterioration of well-being. In the aging male, late-onset hypogonadism affects sexual life, mental health, levels of energy, lower urinary tract symptoms and, therefore, quality of life may be found significantly deteriorated. Testosterone replacement or supplementation therapy has been found efficient to reverse the adverse effects of hypogonadism and improve quality of life. Scales and questionnaires assessing the general health, urinary symptoms, sexual health, and cognition can provide a thorough assessment of the clinical syndrome, optimize treatment, assist the follow-up, and facilitate referrals to other specialties depending on the chief complaint. A systematic assessment might combine several tools, but the optimal ones and the exact usage is unknown. In this narrative review, we are flipping through the literature presenting the available tools per domain for the assessment of quality of life in men on testosterone replacement therapy and we discuss the optimal usage.

Abstract
Several questionnaires have been developed to assist the diagnostic process in obstructive sleep apnea syndrome (OSAS). Berlin Sleep Questionnaire (BSQ) represents a validated screening tool for OSAS. Totally 450 patients admitted to the Sleep Center at Dicle University Medical Faculty were included prospectively. A risk analysis was performed for presence of OSAS using the BSQ. Arterial blood gas measurements were performed including bicarbonate (HCO3) level. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of BSQ for presence of OSAS and severe OSAS were determined. In patients with arterial HCO3 >24.94 mEq/L; sensitivity, specificity, PPV and NPV, of the BSQ were 93.04, 57.1, 98.3, and 23.5%, respectively. The addition of arterial HCO3 value increased the sensitivity of the BSQ in detecting OSAS patients. Although the cost of sleep studies is high for false positives from the BSQ plus arterial HCO3 level, this cost should be compared with the loss of work efficiency and severe healthcare costs of undiagnosed cases in the future. Therefore, finding possible OSAS cases in primary care health centers is important and adding serum HCO3 value to BSQ questionnaire may contribute to this topic.

Abstract
OBJECTIVE To evaluate the effect of the If channel inhibitor, ivabradine on human corpus cavernosum (HCC) smooth muscle tone. METHODS HCC samples were obtained from erectile dysfunction(ED) patients (n = 12) undergoing penile prosthesis surgery. Concentration-response curves for ivabradine were exposed to various inhibitory and stimulatory agents. The relaxant and contractile responses to electrical field stimulation (EFS, 10 Hz and 80 Hz) were examined in the presence or absence of ivabradine (10 μM). HCN3 and HCN4 channel expression and localization were determined by Western blot and immunohistochemical analyses of HCC tissues. RESULTS Increasing ivabradine concentrations dependently reduced the maximal contractile responses of isolated HCC strips induced by KCl (59.5 ± 2.5%) and phenylephrine (84.0 ± 9.8%), which was not affected by nitric oxide synthase and soluble guanylyl cyclase inhibitors after phenylephrine-induced contraction. Nifedipine and tetraethylammonium inhibited the maximum relaxation to ivabradine by 75% and 39.3%, respectively. Fasudil and sildenafil increased the relaxation response to ivabradine without altering the maximum response. Pre-incubation with ivabradine significantly increased relaxant responses to EFS (p < 0.01) and reduced the contractile tension evoked by EFS (72.3%) (p < 0.001). Ivabradine incubation did not affect the expression and localization of HCN3 and HCN4 channels in the HCC smooth muscle cells. CONCLUSIONS Ivabradine exhibits a relaxant effect on HCC tissues, which is likely to be attributed to the blocking of L-type Ca2+ channels and the opening of K+ channels, independent of changes in the activation of the nitric oxide/cyclic guanosine monophosphate system. Inhibition of HCN channels localized in cavernosal smooth muscle cells may offer pharmacological benefits for patients with cardiovascular risk factors.

Abstract
AIM Obstructive sleep apnea syndrome (OSAS) is a chronic and incapacitating disease that often requires lifelong care. This study aimed to evaluate the thiol/disulfide homeostasis in patients with OSAS, to compare the thiol/disulfide levels with the control group and to investigate their relationship with the severity of the disease. MATERIAL AND METHODS Patients who were admitted to the department of chest diseases, and diagnosed with OSAS using polysomnographic analysis (n = 186) and 144 patients who underwent polysomnography due to some reasons but ruled out of having OSAS were included in the study. Serum total thiol (TT), native thiol (SH), and disulfide thiol (SS) levels were measured from the participants; SS/SH, SS/TT, and SH/TT percent ratios were calculated and compared between the patient and control groups. RESULTS The mean (±SD) age of the patients and control participants was 52.0 ± 11.5 years and 44.9 ± 13.2 years, respectively. Compared to the control group, patients with OSAS had significantly lower SH (239.3 ± 56.3 μmol/L vs. 258.6 ± 65.3μmol/L, t = 2.70, p =.007) and TT levels (273.2 ± 60.1 μmol/L vs. 292.9 ± 67.5μmol/L, t = 2.64, p=.010). Age (OR = 1.04), serum albumin (OR = 12.67), ischemia-modified albumin (IMA) (OR = 0.12), SH (OR = 0.81), and TT (OR = 1.17) were independent predictors of OSAS. CONCLUSIONS These results support the idea that decreased ST and TT levels are related to increased oxidative stress. On the other hand, impaired thiol balance may play a significant role in the pathogenesis of OSAS.

Demographic, clinical, and polysomnographic variables of patients were compared as well as the PAP device usage compliance. RESULTS The study was conducted with 183 patients (81 females and 102 males) having the diagnosis of OSAS. The ages of the patients ranged from 37 to 85 years (mean: 58.77 ± 12.59). The incidence of apnea, chest pain, arrhythmia, headache, non-concentration, forgetfulness, psychiatric disorders, motor activity, enuresis, libido and impotence complaints as well as the sedative usage rates and incidence of additional diseases were higher in elderly patients. Apnea hypopnea index, inspiratory positive airway pressure, and expiratory positive airway pressure measurements were significantly higher in the elderly group. The rates of NREM2 (%) and NREM3 (%) were lower in elderly patients. CONCLUSION Many comorbid medical conditions, concomitant drug use, and age-related physiological changes in sleep architecture and circadian rhythm and their effects on sleep should be considered in the elderly sleep.

Abstract
OBJECTIVES Obstructive Sleep apne syndrome is a disease with high morbidity and mortality. The aim of this study was to investigate the conditions affecting the mortality of patients diagnosed with OSAS at six year follow up. METHODS 970 patients who admitted to Sleep laboratory between 2011-2013 were evaluated retrospectively. 74 patients whose mortality data could not be accessed through the system were excluded. The patients who died until April 2019 were compared with the surviving group in terms of demographic, clinical, comorbidities and polysomnographic findings. RESULTS Total 47 patients who died were older, had higher BMI, AHI and ODI values, lower minimum oxygen saturations compared with the survival group (p < .001). In the Cox-hazard regression analysis, BMI (hazard ratio (HR), 1.08; 95% CI, 1.04-1.12), age (1.12, 1.08-1.15), accompanying COPD (2.19, 1.08-4.43), accompanying CAD (2.76, 1.34-5.67) and AHI of >50/h (2.19, 1.19-1.4.05) were reported. CONCLUSION This study showed that OSAS increases the risk of death accompanied by CAD and COPD. It has also been shown that patients with higher AHI (AHI > 50/h) values die more. Therefore, it may be useful to classify the AHI> 50/h group as very severe OSAS instead of severe OSAS.

Abstract
The present study aimed to investigate the frequency of deep venous thrombosis (DVT) among patients with obstructive sleep apnea syndrome (OSAS). Patients who referred the preliminary diagnosis of OSAS were included in this study. D-dimer levels of all patients were measured, and D-dimer (+) patients were evaluated by Doppler USG of the lower-extremity. Mean age of the patient group was 52 ± 12 years and 31.8% (76/239) were women. The rate of D-dimer positivity among severe-OSAS cases (15/85) was significantly higher compared to the rest (13/154) (17.6% and 8.4%, respectively; p = 0.034). The risk of D-dimer positivity was elevated by 2.3 folds in severe-OSAS cases (OR: 2,324, 95% confidence interval: 1.048-5.152). Among 28 D-dimer (+) cases, 4 (14.2%) had DVT as demonstrated by USI of the lower-extremity. All four cases with DVT had severe OSAS. D-dimer was positive in 17.6% (15/85) of all severe OSAS cases. DVT was diagnosed in 4.7% (4/85) of severe-OSAS cases. DVT frequency was 26.6% (4/15) in D-dimer (+) severe-OSAS. Findings of this study indicate that severe-OSAS can be a significant risk factor for DVT. Additionally, data obtained in this study underline the benefits of questioning severe-OSAS patients with respect to DVT symptoms, investigating D-dimer levels and evaluating D-dimer (+) severe-OSAS cases for DVT prophylaxis.

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
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
INTRODUCTION As men age, progressive testosterone deficiency syndrome becomes an increasingly common problem. However, the decreased testosterone levels are not only the result of advanced age. AREAS COVERED PubMed search of published data on testosterone, nutritional deficiency, stress, sleep, and obesity. Many factors impact the male HPG axis (the hypothalamic-pituitary-adrenal), including body weight, calorific and nutritional value of a diet, the amount and quality of sleep, as well as the level of stress. In the case of persons of healthy weight, a below-average calorific value of a diet may decrease the levels of testosterone in men. On the other hand, the same caloric deficiency in obese persons may result in a neutral or positive impact on testosterone levels. EXPERT OPINION Many factors, including external, environmental and internal factors, influence testosterone levels. Undoubtedly, nutritional deficiency, and particularly of such nutrients as zinc, magnesium, vitamin D, together with low polyphenols intake, affects the HPG axis. The levels of mental and oxidative stress can also adversely impact the axis. Hence, a diagnosis of the cause of disturbance in testosterone levels depends on many factors and requires a broad range of research, as well as a change of patients' lifestyle.

Abstract
Aim: The aim of this study was to compare hematological parameters with the mean obstructive apnea duration (MOAD), mean mixed apnea duration (MMAD), mean central apnea duration (MCAD), mean total apnea duration (MTAD) and mean hypopnea duration (MHD), and blood oxygenation, other polysomnographic sleep parameters in patients with severe OSA.Material and methods: A retrospective study included 120 patients with severe OSA. The correlations between the hematological parameters with MOAD, MMAD, MCAD, MTAD, MHD, and blood oxygenation, other polysomnographic sleep parameters were analyzed.Results: There was a positive correlation between hgb with MOAD, MMAD, MTAD MCAD, MHD; mean oxygen desaturation, and the number of desaturation (≥5%). Also, hgb associated negatively with N1 sleep, WASO (wake time after sleep onset) and positively with REM, N2 sleep, total sleep time, and sleep efficiency. RDW and MOAD, MTAD, MHD were negatively related. Also, RDW related positively with sleep latency, WASO, and N1 sleep; negatively with sleep efficiency and REM sleep. There was no relationship between duration of respiratory events with NLR, PRL, and MPV.Conclusions: Hematological parameters, especially hgb and RDW, can be used to assess the severity of the disease in severe OSA patients in addition to AHI.
