The global epidemiology of anabolic-androgenic steroid use: a meta-analysis and meta-regression analysis

Coal to swole: A survey of anabolic steroid use and muscularity concerns in coalfield areas of Wales

BACKGROUND

Growing male anabolic steroid use is often framed as symptomatic of a post-industrial masculinity crisis, but little quantitative evidence exists for this account. We examine whether steroid use is associated with geographic exposure to industrial decline, namely historical coal mining, and whether any association is mediated by masculine norms.

METHODS

We fielded a quota-sampled survey of 18-49 year-old men in Wales (N = 1425). Data were geo-linked to the extent of historic coal mining locally to respondents. Generalised linear mixed models were fitted to test our hypotheses.

RESULTS

Steroid use (odds ratio = 1.99, 1.10-3.60), but not body image (B = 1.06, -2.02-4.13), was positively associated with mining extent. However, this was not mediated by conformity to masculine norms.

DISCUSSION

While use of steroids is more common in former mining areas, this is not due to more prevalent body image issues nor mediated by masculine norms. Thus, accounts of a post-industrial 'thwarted masculinity' do not fit the data. Steroid use in post-industrial areas is an issue for public health and these communities may benefit from targeted interventions to reduce risk of harms.

Prevalence and Correlates of Anabolic-Androgenic Steroid Use in Australian Adolescents

BACKGROUND

Within recent years, there has been a notable lack of research examining the factors associated with adolescent use of anabolic-androgenic steroids (AASs) in Australia, meaning information regarding risk factors of Australian adolescent AAS use is outdated and potentially inaccurate.

METHODS

To address this omission, the present study examined the prevalence and correlates of adolescent (aged 11 to 19 years) AAS use within the EveryBODY study, a large-scale representative survey of adolescents' disordered eating behaviours and body image concerns, involving 5071 adolescents across thirteen schools within the Sydney and Newcastle/Hunter region of New South Wales, Australia.

RESULTS

A total of 1.1% of adolescents reported lifetime use of AAS to increase muscularity. In univariate analyses, increased prevalence of AAS use was associated with male sex (OR = 5.67), identifying as Aboriginal or Torres Strait Islander (OR = 3.80), identifying as same-sex or questioning sexual attraction (OR = 3.17), higher drive for muscularity (OR = 2.19) and weight/shape concerns in the past month (OR = 1.28), and higher frequency of purging (OR = 1.11) and binge eating (OR = 1.09) in the past month. In multivariate analysis, only drive for muscularity (OR = 2.44) and purging behaviours (OR = 1.10) remained as significant correlates. Finally, adolescents who reported lifetime AAS use also reported feeling significantly higher levels of distress and physical and psychosocial impairment compared to adolescents who reported never having used AAS to increase muscularity.

CONCLUSIONS

Positive correlations between disordered eating and weight and shape concerns with AAS use suggests that adolescent AAS use may be conceptualised within the spectra of disordered eating among youth. These findings provide clinicians, carers, and educators with prototypical factors that should assist in the screening of adolescent AAS use to facilitate early intervention.

Adverse Effects of Anabolic Androgenic Steroid Abuse in Athletes and Physically Active Individuals: A Systematic Review and Meta-Analysis

BACKGROUND

Anabolic-androgenic steroids (AAS) are synthetic derivatives of testosterone, primarily used for their anabolic effects in increasing muscle mass. However, AAS have been increasingly abused, posing significant health risks due to their severe effects.

OBJECTIVES

This study aimed to quantify the adverse effects of AAS abuse across a diverse population of various ages. The effects were categorized across cardiovascular, hepatic, endocrine, musculoskeletal, and psychiatric domains.

METHODS

A comprehensive search was conducted across multiple databases following PRISMA guidelines. Study quality was assessed using a modified QUADAS-2 tool, and meta-analyses were performed.

RESULTS

Meta-analysis revealed significant adverse outcomes. AAS use was linked to an increase in systolic blood pressure (BP) by a pooled mean difference (MD) of 12.43 mmHg (95% CI: 9.59 to 15.26) and diastolic BP by 8.09 mmHg (95% CI: 5.62 to 10.57). There was also a significant rise in LDL-C levels, with an MD of 9.12 mg/dL (95% CI: 6.75 to 11.49), indicating heightened cardiovascular risk. Hepatic effects were marked by elevated levels of AST and ALT, with MD of 14.47 U/L (95% CI: 12.41 to 16.52) and 12.16 U/L (95% CI: 3.28 to 21.04), respectively, suggesting significant liver stress or damage. Endocrine disruptions were profound, with a substantial reduction in testosterone levels observed, showing an MD of -141.57 ng/dL (95% CI: -160.42 to -122.72).

CONCLUSIONS

Raising awareness among athletes and physically active people using AAS is crucial. Future research should focus on elucidating the long-term effects of AAS and developing strategies to mitigate the associated risks.

Feasibility of implementing current best clinical practice for people who are using anabolic androgenic steroids within a Swiss primary care practice: a quality assurance study

BACKGROUND

The non-medical use of anabolic androgenic steroids for the improvement of aesthetic and sports performance purposes has become a global substance use disorder, particularly among men in recreational sports. Health outcomes among people who are using anabolic androgenic steroids may be detrimental, yet healthcare services for these users are scarce. Therefore, the aim of this project was to conduct a quality assurance study to evaluate the feasibility of providing current best clinical practice for anabolic androgenic steroids users based on the published literature within a primary care practice in Zurich (Switzerland).

METHODS

A primary healthcare practice for current or past anabolic androgenic steroids use was established at the Arud Centre for Addiction Medicine in Zurich providing specialised medical care for this population. The reporting and methodology to evaluate feasibility of this quality assurance study follow a checklist for pilot studies. The primary feasibility outcomes for this study were satisfaction with the services received (customer satisfaction score), as well as loyalty towards the services (net promoter score). These customer metrics have been used successfully in the medical field to measure patient experiences, as well as infer future word-of-mouth advertisement (i.e. return and refer). Furthermore, the objective was to describe patient characteristics and substance use behaviours in a Swiss context. Patients could access these services in Zurich from 1 June 2023 onwards. The recruitment strategy was word-of-mouth advertising among anabolic androgenic steroids users and paper advertisement (i.e. flyers) about the healthcare service. Eligibility criteria were based on legal restrictions regarding doping laws and professional ethical principles of medicine. In an initial visit at the practice, a focused patient history was assessed, and patients received a physical, psychometric, instrumental as well as laboratory examination. Datasets are summarised using descriptive statistics.

RESULTS

Overall, 34 eligible patients were seen over the period from June until December 2023. Excellent results regarding loyalty towards the service (net promoter score: 100; integer) as well as patient satisfaction with the received services (customer satisfaction score: 100%) were achieved. Patients were commonly young professional males (mean: 38.5 years, standard deviation: 8 years), with educational level beyond compulsory schooling. The main motivation for using anabolic androgenic steroids was aesthetic purposes. Acquisition of these substances occurred mostly through non-medical sources. Patterns of anabolic androgenic steroids use were complex with extensive polypharmacy and concomitant illicit substance use. Most patients suffered from side effects with multiple physical as well as mental health complications. Many abnormal findings were found regarding the physical as well as laboratory and instrumental examination, although mostly mild and transient, some possibly severe regarding health outcomes.

CONCLUSION

With this first quality assurance study, we demonstrate that integration of current best clinical practice for anabolic androgenic steroids users in recreational sports appears to be feasible with high acceptance in a Swiss primary care practice. Furthermore, those patients may engage in high-risk behaviours and a high prevalence of comorbid medical conditions was demonstrated. Anabolic androgenic steroids users likely benefit from integrated medical care provided and coordinated in a primary health care setting. On the basis of the initial study results, these services were continued at a larger scale to further assess as well as mitigate health risks among this user population. Importantly, current doping legislation was demonstrated to be a major limitation to provision of adequate medical care for this user population, thus changes in legislation are crucial to avert this growing public health threat.

The world's first anabolic-androgenic steroid testing trial: A two-phase pilot combining chemical analysis, results dissemination and community feedback

BACKGROUND AND AIMS

The clandestine production and distribution of anabolic-androgenic steroids (AAS) poses health risks due to the uncertainty of their contents. This study aimed to test the chemical content of AAS samples and provide aggregate results back to the community, exploring how these results influenced usage decisions and risk management.

DESIGN

A mixed-methods approach was used, combining chemical analysis of AAS samples with qualitative interviews. Participants submitted samples for testing, and the results were later shared with them. Semi-structured interviews explored participants' perceptions of AAS risks and the impact of testing results on their behaviour.

SETTING

The study was conducted at CheQpoint drug checking service in Brisbane, Australia.

PARTICIPANTS

Thirty-two samples were submitted for testing between 19 April and 7 June 2024, with 23 samples analysed. A total of 25 active AAS users participated in interviews.

MEASUREMENTS

Chemical analyses identified substances present and assessed active ingredient concentrations. Qualitative interviews gathered participants' perceptions, and these data were analysed through iterative categorisation, guided by the Health Belief Model.

FINDINGS

Chemical analysis identified that 13% of samples contained substances different from what was expected. Concentrations of active ingredients were close to expected levels [e.g. testosterone propionate at 96.2 mg/mL (range = 91.39-101.01 mg/mL)]. Interviews identified four key theme categories. Participants sought testing primarily for substance verification, expressing concerns about contamination and dosage. Barriers to testing included limited access and fear of disclosure. While testing was seen as a valuable harm reduction tool, gaps in health guidance and follow-up support were identified as areas for improvement.

CONCLUSIONS

Thirteen percent of 23 anabolic-androgenic steroid (AAS) samples analysed contained substances different from what was expected. Interviews with active AAS users highlighted the need for reliable information, accessible testing services and tailored health approaches for AAS use.

Coordination in treatments for people who use anabolic androgenic steroid (AAS) - Experiences of professionals

Aims: Research has identified the use of anabolic-androgenic steroids (AAS) as a gap between treatment needs and available facilities for substance use disorder (SUD) treatment in Norway. State policy emphasizes the need for measures to ensure coordinated treatment services. This study aims to explore whether clinical pathways of mental health and substance abuse and team-based organisation function as intended in the treatment of patients with AAS use. Design: A qualitative research design was used. Individual semi-structured in-depth interviews were conducted with eight professionals who we assumed had experience with this patient group. The participants were asked about the clarification process regarding assessment and treatment for AAS and internal and external cooperation. Everyday work, roles and task distribution, structure and routines, and knowledge of AAS were topics that were addressed. We analysed by interpreting the data considering relevant theoretical perspectives of organisational- and sociology of profession perspective. Results: We found that it was arbitrary whether AAS use was discovered, which may indicate a lack of attention to this form of abuse. Organisation in teams seems to as an adequate horizontal coordination mechanism within SUD treatment. However, the teams lacked both knowledge of AAS as well medical expertise, which may lead to a lack of a treatment programme that is in line with the patient's needs. Conclusion: There still seems to be a need for increased awareness of AAS among the professionals and organisations involved. Team-based organisation within SUD seemed to function well, however loss of coordination between SUD and local services may indicate that the clinical pathway for mental health and substance abuse do not function as intended.

Excessive androgen exposure and risk of malignancies: A cohort study

BACKGROUND

A link between androgen use and the risk of cancers, especially prostate and breast cancer, has been suggested. The knowledge about a possible association is limited.

OBJECTIVE

The study aimed to investigate cancer incidence rates, particularly those related to prostate and breast cancer, in male androgen users and compare them to a control group.

METHODS

We included male androgen users identified through a nationwide anti-doping testing program in Danish fitness centers from 2006 to 2018. We paired each case with 50 male controls of the same age, selected randomly. The cohort was followed from baseline and until 2023. The outcome was the incidence of prostate cancer, breast cancer, or any cancer excluding non-melanoma skin cancer.

RESULTS

The study included 1,189 androgen users and 59,450 controls, with a mean age of 27 years at enrolment. During the follow-up period with a mean length of 11 years, 13 androgen users, and 612 controls were diagnosed with cancer. This resulted in an incidence rate ratio of 1.05 (95% CI: 0.55-1.81). None of the androgen users were diagnosed with prostate or breast cancer.

DISCUSSION AND CONCLUSION

Male androgen users did not face an increased short-term risk of cancer, neither overall nor related to prostate or breast cancer. Our study indicates that the absolute risk of malignancies in androgen users is comparable to that in the background population. However, we cannot exclude androgens as a cancer risk factor due to the limited sample size, relatively short follow-up period, and subject age.

Abnormalities in Blood Parameters in Athletes Taking Anabolic Androgenic Steroidal Agents; an Observational Clinical Study

Background

Many studies indicate that high and multiple doses of anabolic-androgenic steroids (AAS) for athletic enhancement can result in serious and irreversible adverse effects. A study that includes laboratory blood testing to evaluate the direct effects of AAS agents among users has not been previously undertaken. The purpose of this study was to investigate the adverse effects of the use of AAS by athletes and to determine whether AAS use leads to changes in certain blood parameters.

Methods

This is an observational study consisting of two stages. First, the participants completed an online questionnaire assessing sociodemographic characteristics, and knowledge and attitudes towards AAS. Second, volunteers underwent laboratory blood testing. Analysis was conducted using frequency distributions and percentages of responses across various variables.

Results

Thirty-one individuals completed the online questionnaire, 18 of whom continued to stage 2, where blood samples were taken to trace any changes in blood parameters. All the participants were male, with an age range of 24-45 years. The results showed that 94% of the participants used AAS for nontherapeutic purposes. Most participants reported that they take a combination of AAS (96%), as well as in combination with other supplements (74%). The most used combination was testosterone plus growth hormone (45%), and the most used supplements were liver protectors (84%). Seventy-four percent of the participants reported side effects, and 28% had received a medical diagnosis, such as hypertension, hyperlipidemia or an infertility. High levels of testosterone, prolactin, alanine transaminase (ALT), aspartate transferase (AST) and lipid profile, and low luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were observed.

Conclusion

The unsupervised use of AAS alone or in combination with other hormones and/or supplements may lead to adverse effects. Further studies with larger samples are needed to draw significant conclusions about the safety of using AAS.

Clinician's guide to the management of azoospermia induced by exogenous testosterone or anabolic-androgenic steroids

ABSTRACT

Azoospermia, defined as the absence of sperm in the ejaculate, is a well-documented consequence of exogenous testosterone (ET) and anabolic-androgenic steroid (AAS) use. These agents suppress the hypothalamic-pituitary-gonadal (HPG) axis, leading to reduced intratesticular testosterone levels and impaired spermatogenesis. This review examines the pathophysiological mechanisms underlying azoospermia and outlines therapeutic strategies for recovery. Azoospermia is categorized into pretesticular, testicular, and post-testicular types, with a focus on personalized treatment approaches based on the degree of HPG axis suppression and baseline testicular function. Key strategies include discontinuing ET and monitoring for spontaneous recovery, particularly in patients with shorter durations of ET use. For cases of persistent azoospermia, gonadotropins (human chorionic gonadotropin [hCG] and follicle-stimulating hormone [FSH]) and selective estrogen receptor modulators (SERMs), such as clomiphene citrate, are recommended, either alone or in combination. The global increase in exogenous testosterone use, including testosterone replacement therapy and AAS, underscores the need for improved management of associated azoospermia, which can be temporary or permanent depending on individual factors and the type of testosterone used. Additionally, the manuscript discusses preventive strategies, such as transitioning to short-acting testosterone formulations or incorporating low-dose hCG to preserve fertility during ET therapy. While guidelines for managing testosterone-related azoospermia remain limited, emerging research indicates the potential efficacy of hormonal stimulation therapies. However, there is a notable lack of well-structured, controlled, and long-term studies addressing the management of azoospermia related to exogenous testosterone use, highlighting the need for such studies to inform evidence-based recommendations.

Is genotoxicity a suitable biomarker for monitoring anabolic-androgenic steroids exposure in vivo? A systematic review and meta-analysis

Steroids stand for a class of hormones (natural and synthetic) known to be helpful for a number of disorders. Despite the aforementioned beneficial effects of using these hormones, anabolic-androgenic steroids (AAS) are also widely abused in a non-therapeutic manner for muscle-building and strength-increasing properties that may lead to genotoxicity in different tissues. The present study aims to understand whether genotoxicity may be a suitable biomarker for AAS exposure in vivo in both experimental animal and human studies. All studies published in PubMed/Medline, Scopus, and Web of Science electronic databases that presented data on DNA damage caused by AAS were analyzed. A total of 15 articles were included in this study, and after thoroughly reviewing the studies, a total of 8 articles were classified as Strong, 6 were classified as Moderate, and only 1 was classified as Weak, totaling 14 studies being considered either Strong or Moderate. This classification makes it possible to consider the present findings as reliable. The meta-analysis data revealed a statistically significant difference in Wistar rat testis cells with AAS compared to control for tail length and % tail DNA (p < 0.001), so that the selected articles were considered homogeneous and the I2 of 0% indicated low heterogeneity. In summary, genotoxicity can be considered a suitable biomarker for monitoring AAS exposure as a result of DNA breakage and oxidative DNA damage.

What is the prevalence of anabolic-androgenic steroid use among women? A systematic review

BACKGROUND AND AIM

Evidence suggests there has been an increase in anabolic-androgenic steroid (AAS) use among women, driven by the evolving landscape of women's participation in sport. However, the extent of use is unknown. This systematic review aimed to estimate the prevalence of women's AAS use.

METHOD

We conducted a systematic review of peer-reviewed articles in English, focusing on AAS use among women aged 18 and above. We excluded grey literature and studies that measured doping through some form of analysis (e.g. urine or hair). Searched databases were MEDLINE, CINAHL, PsycINFO, SocINDEX, SPORTDiscus, Embase and Cochrane Library. Titles and abstracts for all articles were screened, followed by full-text assessment and data extraction of included articles by multiple authors for accuracy. The pooled prevalence of lifetime use was determined using a random effects model and the risk of bias was assessed using the Joanna Briggs Institute Prevalence Critical Appraisal Tool.

RESULTS

Based on 18 studies, participant numbers averaged 669 per study (median = 189; range = 16 to 7051). The overall pooled AAS use prevalence was 4% (95% confidence interval [CI] = 2-9%) with high heterogeneity overall (I2 = 95%). In the subgroup analysis, AAS use prevalence was 16.8% (95% CI = 11.0-24.9%, I2 = 44%) in the bodybuilder subgroup, 4.4% (95% CI = 1.2-15.1%, I2 = 93%) in athletes/recreational gym user subgroup, and 1.4% (95% CI = 0.4-4.7%, I2 = 96%) in the general population/other subgroup. Meta-regression demonstrated significantly higher AAS use in bodybuilders compared with the other subgroup (P = 0.011).

CONCLUSION

Anabolic-androgenic steroid use among women appears to be substantially higher among bodybuilders and athletes/recreational gym users than the general female population.

Off-label use of clomiphene citrate to treat anabolic androgenic steroid induced hypogonadism upon cessation among men (CloTASH) - A pilot study protocol

Background

Non-prescribed anabolic androgenic steroid (AAS) use is associated with AAS-induced hypogonadism (ASIH), and metabolic, cardiovascular, and mental health risks. Symptoms of ASIH (fatigue, depression, anxiety, sexual dysfunction) are hard to endure following cessation, but there is no consensus on whether endocrine treatment should be used to treat ASIH. This proof-of-concept study aims to explore safety of off-label clomiphene citrate therapy, whether the treatment will reduce the symptoms of androgen deficiency, and to study changes in health risks after cessation.

Methods

In this open-labeled non-randomized off-label hormone intervention pilot study, we shall include males with AAS dependence intending to cease use. The 16-week intervention included clomiphene citrate, transdermal testosterone gel for the first four weeks and optional human chorionic gonadotropin (hCG) from week 4 if low treatment response. Measures of physical and mental health will be examined from ongoing AAS use, during the intervention, and at 6- and 12 months post cessation. Change in self-reported symptoms of hypogonadism and other withdrawal symptoms will be compared with data from a group of men who ended AAS use temporarily without the medical intervention. The study may provide valuable clinical insights and may be used to inform the design of future intervention studies.

"The compounds for females are really commonly faked!": Women's challenges in anabolic steroid acquisition and the place of drug checking interventions

INTRODUCTION

Women who use drugs, particularly those using anabolic-androgenic steroids (AAS), encounter heightened social risks influenced by the legal status of AAS, varying regionally. In jurisdictions where AAS are legal, medical guidance and prescription are common, while in illegal regions, there are challenges associated with acquisition and safer usage. Therefore, we aimed to explore the experiences of women who use AAS in Australia, where these substances are criminalised, with a focus on the challenges they encounter in acquiring and using these drugs.

METHODS

We focused on data from six women in a broader study interviewing 15 AAS users. The data were subjected to iterative inductive analysis, resulting in two theme-categories.

RESULTS

Women who use AAS face distinct challenges in accessing reliable suppliers, with men seemingly having 'easier' access. Women experience this disparity as increasing their vulnerability to unsafe products, further compounded by their lack of knowledge regarding these substances. Moreover, mislabelling and counterfeiting of female-specific AAS substances is described to further compound these risks, reflecting the participants' expressed need for enhanced intervention and quality control in the AAS market.

DISCUSSION AND CONCLUSIONS

Ensuring product reliability, transparency and accountability are perceived as essential for the health and safety of women who use AAS. To address these issues, interventions should provide women with comprehensive drug checking services tailored to their health needs. 'Steroid literacy' must be an integral component, equipping women with knowledge to make informed decisions in the gendered AAS market.

The health effects of non-prescribed anabolic-androgenic steroid use: Findings from The Performance and image-enhancing drugs UseRS' Health (PUSH) audit

INTRODUCTION

To ascertain the adverse health outcomes experienced by those using prescribed testosterone and non-prescribed anabolic-androgenic steroids presenting to general practitioner (GP) clinics.

METHODS

Retrospective clinical audit from nine GP clinics in major metropolitan areas across three Australian states. Data included demographic and individual characteristics (age, sexuality, body mass index, smoking status and HIV status); performance and image-enhancing drug use (type, reasons for use, patient-reported adverse effects); and blood biochemistry measurements (lipid profiles, liver function tests and red blood cell tests). Adverse health outcomes included evidence of polycythaemia, hypertension, liver abnormalities and hypercholesterolemia.

RESULTS

Three hundred men were identified as either using prescribed testosterone (66%; n = 197) or non-prescribed anabolic-androgenic steroids (AAS) (34%; n = 103). Individuals in the prescribed group were more likely to be older (p < 0.001), gay or bisexual (p < 0.001) and living with diagnosed HIV (p < 0.001) compared to individuals in the non-prescribed group. Abnormal liver function, polycythemia and gynecomastia were the top three adverse events experienced. When adjusting for age, sexuality, HIV status and smoking status, those who used non-prescribed AAS were more likely to experience any adverse event (aPR = 1.28; 95% CI 1.01-1.60; p = 0.038), hypertension (aPR = 1.86; 95% CI 1.19-2.91; p = 0.006) and liver abnormalities (aPR = 1.51; 95% CI 1.04-2.20; p = 0.030) compared to those using prescribed testosterone.

DISCUSSION AND CONCLUSION

For GPs who have clients who may be using, or who they suspect of using, AAS, these findings highlight the importance of not only exploring a patient's history of the adverse effects they have experienced, but that measuring for these other conditions may provide a more accurate clinical picture.

Abuse of Anabolic-Androgenic Steroids as a Social Phenomenon and Medical Problem-Its Potential Negative Impact on Reproductive Health Based on 50 Years of Case Report Analysis

Background/Objectives: Illegal anabolic-androgenic steroids are a significant lifestyle factor in infertility. The aim of our study was to analyze clinical cases resulting from their use for their frequency, geographical location, dynamics, substances used, the age and gender of the users, and the types of clinical complications. Methods: Publications were obtained by searching PubMed for the following terms: 'anabolic-androgenic steroids' and 'clinical case'. Publications from 1973 to 2022 were qualified for the analysis. Results: An increasing trend in the number of clinical cases resulting from the use of steroids, as well as the number of substances used simultaneously, was observed. The substances changed over the decades, but in the last 20 years, testosterone, nandrolone, stanozolol, methandienone, trenbolone, and methenolone have predominated. Cardiological side effects predominated in each period, with a continuous increase in their occurrence. The most common among these were myocardial infarctions and hypertrophic cardiomyopathy. The next most numerous adverse events involved psychiatric, endocrinological, hepatic, and oncological problems. We demonstrated a possible relationship between the use of individual steroids and medical issues; the strongest associations were between testosterone and endocrine complications, and methylstenbolone and hepatic complications. Conclusions: There has been an increasing trend in case reports describing serious health problems associated with the use of anabolic-androgenic steroids, a tendency to use several substances simultaneously, and a preferential use of substances with a high potential of causing serious side effects. These phenomena mainly concern men, with an average age of 30, and the health problems that dominate in clinical case reports-including serious cardiological, psychiatric, endocrinological, hepatic, and oncological diseases-may potentially affect reproductive health and pose a challenge for reproductive medicine.

Effects of a supraphysiological dose of testosterone cypionate on salivary gland function in adult male Wistar rats

The abusive use of anabolic androgenic steroids has become a serious health problem worldwide, but its effects on oral health are still poorly understood. Therefore, the objective of this study was to evaluate the effects of a supraphysiological dose of testosterone cypionate (TC) on salivary biochemical, histomorphology, immunohistochemistry, and redox state parameters of parotid and submandibular glands. Twenty male Wistar rats, 12 weeks old, were divided into two groups (n=10/group): a control group and TC group, which received a dose of 20 mg/kg, once a week, for 6 weeks. Post treatment, the saliva and glands were collected. A supraphysiological dose of TC increased plasma and salivary testosterone concentrations. Although TC did not alter salivary flow, pH, and buffering capacity, the treatment increased the salivary secretion of total protein and reduced amylase, calcium, phosphate, and potassium. TC reduced the connective tissue area in the parotid gland and acinar area of the submandibular gland, while increasing the granular convoluted tubule area in the submandibular gland. Proliferating cell nuclear antigen was higher in the acinar cells of the submandibular glands from the TC group. Moreover, TC increased concentrations of total oxidant capacity and damaged lipids in both salivary glands, while total antioxidant activity and uric acid were lower in the submandibular gland, and reduced glutathione was higher in both glands. Superoxide dismutase, catalase, and glutathione peroxidase activities were higher in the parotid gland, while only glutathione peroxidase activity was lower in the submandibular gland of the TC group. In conclusion, TC abuse may be a potential factor for dysfunction of the parotid and submandibular glands, becoming a risk factor for the oral and systemic health of users.

Some for a Good Time, Some for a Long Time: Women's Ratings of the Mate Value of Men with Different Addictions - An Experimental Study

Background: The present study aimed to explore women's perception of men with different addictions in terms of their short- and long-term mate value. Objectives: 2,525 women (age range: 18-40, M = 28.35, SD = 6.39) were randomized to six conditions in a vignette-based experiment where a male of otherwise high mating value was described as suffering from either gambling, gaming, cannabis, anabolic androgenic steroid, and alcohol addiction or as not suffering from addiction (control). Results: Regarding long-term mate value of the target, the control target was rated higher than each of the targets. The gaming target was rated higher than the alcohol, cannabis, and gambling targets. Finally, the AAS target was rated as higher on long-term mate value than the alcohol and gambling addiction targets. Conclusions: Overall, women seem to perceive risk-taking in the face of uncertainty, reflected by gambling addiction, as an attractive behavioral tendency in men in terms of short-term mating. In contrast, potential long-term mates with gaming or chemical addictions are viewed more negatively, probably because it signals inadequate time and resources to be invested in a relationship.

Evaluation of structural features of anabolic-androgenic steroids: entanglement for organ-specific toxicity

Anabolic-androgenic steroids (AASs), more correctly termed "steroidal androgens", are a broad category of compounds including both synthetic derivatives and endogenously produced androgens like testosterone, which have long been employed as performance-enhancing substances, primarily among recreational athletes and some professionals. While their short-term effects on muscle physiology are well-documented, the long-term health consequences remain inadequately understood. A key finding is the disruption of hormone production, leading to reversible and irreversible changes, particularly with prolonged use. While debate exists over the prevalence of adverse effects, studies suggest a spectrum of somatic and psychiatric consequences, highlighting the need for improved understanding and prevention strategies. AASs are not only affect muscle structure but also influence mood, behavior, and body image, potentially exacerbating substance dependence and psychological distress. Liver alterations are a prominent concern, with oxidative stress implicated in AAS-induced hepatotoxicity. Reproductive complications, including gonadal atrophy and infertility, are common, alongside virilization and feminization effects in both genders. Cardiovascular effects are particularly worrisome, with AASs implicated in hypertension, dyslipidemia, and increased thrombotic risk, contributing to cardiovascular morbidity and mortality. Moreover, AASs may enhance cancer risks, potentially accelerating carcinogenesis in various tissues, including the prostate. The review emphasizes the need for comprehensive public health initiatives to mitigate harm, including harm minimization strategies, routine health screenings, and targeted interventions for AAS users. Understanding the complex interplay of biological mechanisms and systemic effects is crucial for informing clinical management and preventive measures. This review also examines the biological impact of AASs on human muscles, detailing mechanisms of action, chemistry, and associated health risks such as liver damage, cardiovascular disease, and endocrine dysfunction.

Nandrolone Abuse Prior to Head Trauma Mitigates Endoplasmic Reticulum Stress, Mitochondrial Bioenergetic Deficits, and Markers of Neurodegeneration

The abuse of synthetic steroids, such as nandrolone decanoate (ND), is often associated with violent behavior, increasing the risk of traumatic brain injury (TBI). After a TBI, proteins like APP, β-amyloid peptide-42 (Aβ42), and phosphorylated tau (pTau) accumulate and trigger endoplasmic reticulum (ER) stress associated with an unfolded protein response (UPR). The involvement of mitochondrial bioenergetics in this context remains unexplored. We interrogate whether the abuse of ND before TBI alters the responses of ER stress and mitochondrial bioenergetics in connection with neurodegeneration and memory processing in mice. Male CF1 adult mice were administered ND (15 mg/kg) or vehicle (VEH) s.c. for 19 days, coinciding with the peak day of aggressive behavior, and then underwent cortical controlled impact (CCI) or sham surgery. Spatial memory was assessed through the Morris water maze task (MWM) post-TBI. In synaptosome preparations, i) we challenged mitochondrial complexes (I, II, and V) in a respirometry assay, employing metabolic substrates, an uncoupler, and inhibitors; and ii) assessed molecular biomarkers through Western blot. TBI significantly increased APP, Aβ42, and pTauSer396 levels, along with ER-stress proteins, GRP78, ATF6, and CHOP, implying it primed apoptotic signaling. Concurrently, TBI reduced mitochondrial Ca2+ efflux in exchange with Na+, disturbed the formation/dissipation of membrane potential, increased H2O2 production, decreased biogenesis (PGC-1⍺ and TOM20), and ATP biosynthesis coupled with oxygen consumption. Unexpectedly, ND abuse before TBI attenuated the elevations in APP, Aβ42, and pTauSer396, accompanied by a decrease in GRP78, ATF6, and CHOP levels, and partial normalization of mitochondrial-related endpoints. A principal component analysis revealed a key hierarchical signature featuring mitochondrial Ca2+ efflux, CHOP, GRP78, TOM20, H2O2, and bioenergetic efficiency as a unique variable (PC1) able to explain the memory deficits caused by TBI, as well as the preservation of memory fitness induced by prior ND abuse.

Elevated interleukin 8 and matrix metalloproteinase 9 levels are associated with myocardial pathology in users of anabolic-androgenic steroids

AIMS

In the current paper, we aim to explore the effect of both current and former long-term anabolic-androgenic steroid (AAS) use on regulation of systemic inflammatory markers and mediators of extracellular matrix (ECM) remodelling and their association with hormones and echocardiographic myocardial pathology in weightlifters.

METHODS AND RESULTS

In a cross-sectional study, 93 weightlifting AAS users, of whom 62 were current and 31 were past users, with at least 1-year cumulative AAS use (mean 11 ± 7 accumulated years of AAS use), were compared with 54 non-using weightlifting controls (WLCs) using clinical interview, blood pressure measurements, and echocardiography. Serum levels of interleukin (IL)-6, IL-8, tumour necrosis factor (TNF), interferon (IFN)-γ, growth differentiation factor (GDF)-15, and matrix metalloproteinase (MMP)-9, sex hormones, and lipids were analysed. It was found that serum levels of IL-8, GDF-15, and MMP-9 were significantly increased in current AAS users compared with former users and WLCs. Matrix metalloproteinase 9, but not IL-8, correlated consistently with sex hormone levels, and sex hormone levels correlated consistently with mean wall thickness, in current users. Moreover, HDL cholesterol was significantly lower in current vs. former AAS users and significantly inversely correlated with MMP-9 in current users. Further, in current users, MMP-9 and IL-8 correlated with markers of myocardial strain, and MMP-9 also correlated with indices of cardiac mass, which was not seen in former users. Mediation analyses suggested that MMP-9 could partly explain hormone-induced alterations in markers of myocardial damage in current users.

CONCLUSION

Long-term AAS is associated with increased levels of markers of inflammation and ECM remodelling, which seems to have a hormone-dependent (MMP-9) and a hormone-independent (IL-8) association with markers of myocardial dysfunction.

Prediction model for anabolic androgenic steroid positivity in forensic autopsy cases - a new tool to the autopsy room

Non-prescription use of anabolic androgenic steroids (AAS) is associated with an increased risk of premature death. However, these substances are seldom screened in connection with forensic cause-of-death investigation, unless the forensic pathologist specifically suspects use, often based on a positive AAS use history. Since AAS use is often concealed from others, this practice may lead to mistargeting of these analyses and significant underestimation of the true number of AAS positive cases undergoing forensic autopsy. Thus, more accurate diagnostic tools are needed to identify these cases. The main objective of this study was to determine, whether a multivariable model could predict AAS urine assay positivity in forensic autopsies. We analyzed retrospectively the autopsy reports of all cases that had been screened for AAS during forensic cause-of-death investigation between 2016-2019 at the Finnish Institute for Health and Welfare forensic units (n = 46). Binary logistic regression with penalized maximum likelihood estimation was used to generate a nine-variable model combining circumferential and macroscopic autopsy-derived variables. The multivariable model predicted AAS assay positivity significantly better than a "conventional" model with anamnestic information about AAS use only (area under the receiver operating characteristic curve [AUC] = 0.968 vs. 0.802, p = 0.005). Temporal validation was conducted in an independent sample of AAS screened cases between 2020-2022 (n = 31), where the superiority of the multivariable model was replicated (AUC = 0.856 vs. 0.644, p = 0.004). Based on the model, a calculator predicting AAS assay positivity is released as a decision-aiding tool for forensic pathologists working in the autopsy room.

Reduced plakoglobin increases the risk of sodium current defects and atrial conduction abnormalities in response to androgenic anabolic steroid abuse

Androgenic anabolic steroids (AAS) are commonly abused by young men. Male sex and increased AAS levels are associated with earlier and more severe manifestation of common cardiac conditions, such as atrial fibrillation, and rare ones, such as arrhythmogenic right ventricular cardiomyopathy (ARVC). Clinical observations suggest a potential atrial involvement in ARVC. Arrhythmogenic right ventricular cardiomyopathy is caused by desmosomal gene defects, including reduced plakoglobin expression. Here, we analysed clinical records from 146 ARVC patients to identify that ARVC is more common in males than females. Patients with ARVC also had an increased incidence of atrial arrhythmias and P wave changes. To study desmosomal vulnerability and the effects of AAS on the atria, young adult male mice, heterozygously deficient for plakoglobin (Plako+/-), and wild type (WT) littermates were chronically exposed to 5α-dihydrotestosterone (DHT) or placebo. The DHT increased atrial expression of pro-hypertrophic, fibrotic and inflammatory transcripts. In mice with reduced plakoglobin, DHT exaggerated P wave abnormalities, atrial conduction slowing, sodium current depletion, action potential amplitude reduction and the fall in action potential depolarization rate. Super-resolution microscopy revealed a decrease in NaV1.5 membrane clustering in Plako+/- atrial cardiomyocytes after DHT exposure. In summary, AAS combined with plakoglobin deficiency cause pathological atrial electrical remodelling in young male hearts. Male sex is likely to increase the risk of atrial arrhythmia, particularly in those with desmosomal gene variants. This risk is likely to be exaggerated further by AAS use. KEY POINTS: Androgenic male sex hormones, such as testosterone, might increase the risk of atrial fibrillation in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), which is often caused by desmosomal gene defects (e.g. reduced plakoglobin expression). In this study, we observed a significantly higher proportion of males who had ARVC compared with females, and atrial arrhythmias and P wave changes represented a common observation in advanced ARVC stages. In mice with reduced plakoglobin expression, chronic administration of 5α-dihydrotestosterone led to P wave abnormalities, atrial conduction slowing, sodium current depletion and a decrease in membrane-localized NaV1.5 clusters. 5α-Dihydrotestosterone, therefore, represents a stimulus aggravating the pro-arrhythmic phenotype in carriers of desmosomal mutations and can affect atrial electrical function.

Anabolic steroid consumption among gym-goers in Amman: knowledge, attitudes, and behaviors

Background

The use of Anabolic-androgenic steroids (AAS) among gym members has become a significant concern due to their impact on physical training and performance. Research worldwide indicates a notable prevalence of AAS use among athletes and gym attendees, often involving substances that are neither safe nor legal.

Objectives

This study aims to determine the prevalence of AAS use among gym attendees in Amman, Jordan, and to explore the knowledge, attitudes, and behaviors associated with AAS use.

Methods

The study involved 399 participants from 35 randomly selected gyms in the metropolitan area of Amman, Jordan. A cluster sampling technique was used to select a diverse and representative sample of gym attendees. Data was collected using a self-administered questionnaire that assessed AAS use, knowledge, attitudes, and behavioral factors. Statistical analyses were conducted using chi-square tests to explore the relationships between AAS use and categorical variables, while logistic regression was employed to identify predictors of AAS use.

Results

The analysis revealed significant associations between AAS use and various factors, including knowledge, attitudes, behavioral factors, and demographic variables such as gender, age, exercise frequency, reasons for exercise, and total exercise duration. The study identified key predictors of AAS use among gym attendees in Amman, highlighting the importance of demographic and behavioral factors.

Conclusion

The findings underscore the need for targeted interventions to address misconceptions and promote safer practices among gym-goers in Amman. The study provides critical insights that can guide the development of strategies, policy adjustments, and educational initiatives aimed at reducing AAS misuse and fostering a healthier gym culture in the region.

Changing trends in anabolic-androgenic steroid use within Scottish prisons: Detection, prevalence, and quantitation

Anabolic-androgenic steroids (AASs) are a subclassification of image performance enhancing drugs (IPEDs). While AAS use is most prevalent among people in athletics, there is also high lifetime prevalence of AAS use among prisoners. This study reports the qualitative detection of AASs in seized samples from the Scottish prisons from 2019-2023. Additionally, methods were developed for the quantitative analysis of AASs using gas chromatography-mass spectrometry (GC-MS) and applied to 61 samples of tablets or powders seized from Scottish prisons between July 2022 and July 2023. Since 2022, there has been an increase in AAS detections in the Scottish prisons. Oxymetholone was the most prevalent AAS, followed by metandienone (methandrostenolone, methandienone), methyltestosterone, oxandrolone, mestanolone (methylandrostanolone), stanozolol, and androstenedione. Multiple AASs were found in 21 samples and 10 samples contained other drugs, including amitriptyline, sertraline, zopiclone, mirtazapine, sildenafil, etizolam, Δ9-tetrahydrocannabinol, and the synthetic cannabinoid MDMB-INACA. Most AAS samples were tablets (77.0%), although they were also detected in powders, herbal material, e-cigarettes, and a fragmented soap bar-type sample. There was a large variation in the concentration of AASs in the tablets and powders seized from the Scottish prisons, demonstrating AASs are another highly variable component of the polydrug use situation in prisons, the effects of which need to be examined further.

Distal Triceps Tendon Repair in Strength Athletes Leads to Satisfactory Return to Sports: A Retrospective Analysis of 22 Cases

Background: Distal triceps brachii tendon rupture (DTTR) is a relatively rare injury that is common in bodybuilding and high-intensity contact sports and can lead to significant functional impairment of the elbow joint. This study was conducted to evaluate clinical outcomes and the rate of return to sports among competitive bodybuilders and high-demand strength athletes after surgical repair of DTTR. Methods: This retrospective case series was performed in an institutional setting in tertiary health care. Return to sports of 22 competing or high-demand strength athletes (meaning three or more exercises per week) were analyzed pre- and postoperatively after surgical repair of DTTR using a hybrid technique of transosseous sutures and anchor fixation. Descriptive statistics were used to analyze demographic variables, and independent and paired t-tests were used to assess clinical outcomes. Results: The follow-up showed that from pre- to postoperatively, there was no deterioration in the number of sports disciplines (2.4 and 2.5 sporting activities per person, respectively; p = 0.540) or in the frequency of weekly training (4.1 and 4.1 times per person, respectively; p = 0.329). The postoperative visual analog scale for pain (from 6.0 to 1.6, p < 0.001), level of fitness (from 5.1 to 2.6, p = 0.002), and ability to train (from 5.2 to 1.3, p < 0.001) improved significantly. The time of return to sports was 1.5-3 months and 4-6 months after the surgery for ten patients each. The overall rate of return to sports was 95%, whereas 86% returned to the preinjury level of sporting activity. Conclusions: Repair of DTTR leads to high rates of return to sports in competitive athletes.

Impaired vascular function among young users of anabolic-androgenic steroids

Supraphysiological doses of anabolic-androgenic steroids (AAS) is popular among recreational weightlifters and bodybuilders due to the performance-enhancing properties but is also associated with adverse cardiovascular effects. The knowledge about how AAS affect the vasculature is limited, although results from previous studies suggest alterations in vasoreactivity and morphology. In the present study we investigate the association between long-term use of AAS and vascular function. Hundred and twenty-three males were included in the study, 56 of them current AAS users and 67 weightlifting controls. Vascular function was evaluated by carotid artery reactivity and flow-mediated dilation. AAS users had significantly reduced carotid artery reactivity (p < 0.001) and flow-mediated dilation (p < 0.001) compared to weightlifting controls. Results from the present study indicate that long-term use of AAS affect the cardiovascular system negatively, measured as reduced carotid artery reactivity and flow-mediated dilation. These findings could partly explain sudden cardiovascular events among young long-term users of AAS.

Non-ischemia Cardiomyopathy and Polycythemia Secondary to Anabolic-Androgenic Steroid Use

Athletes and bodybuilders use anabolic-androgenic steroids (AAS) to increase muscle mass and enhance performance. Its use is widespread among competitive athletes in order to enhance athletic performances. However, the use of AAS has been linked to many deleterious adverse effects, including cardiomyopathy and polycythemia. We present the case of a young man in his late 20s who presented with uncontrolled hypertension and elevated hemoglobin. He was found to have a reduced left ventricular ejection fraction of 20-25%. Further workup showed dilated cardiomyopathy and low normal erythropoietin (EPO) levels. Evaluation for polycythemia vera was negative, and there was no evidence of ischemic cardiomyopathy. The patient later admitted to using injected AAS for professional bodybuilding. The coexistence of both these conditions can be challenging to diagnose and treat. While primary and secondary polycythemia can lead to hyperviscosity and result in ischemic cardiomyopathy from coronary occlusion, anabolic steroids can directly result in cardiomyopathy and polycythemia. This case points to the importance of identifying cardiomyopathy and polycythemia from illicit drug use, which can often be missed, and the workups needed to identify the etiology.

The relationship between anabolic androgenic steroid use and body image, eating behavior, and physical activity by gender: A systematic review

The prevalence of anabolic androgenic steroids (AAS) is rising, especially in recreational sports and the general population. While body image significantly influences AAS use, gender differences remain unclear. We examined gender-related connections between AAS use, body image, eating behavior, and physical activity. Following PRISMA guidelines, we analyzed 22 studies: 14 with male-only samples, 5 mixed-gender, 2 with sexual and gender minorities, and 1 with a female-only sample. FINDINGS: confirm body image as a key predictor of AAS use. Though AAS use correlates with eating disorders, outcomes vary by context; for instance, no discernible difference in eating behavior was observed between AAS users and non-users in bodybuilding. Physical activity findings varied, with some studies showing no significant differences between AAS users and non-users. Due to limited gender-comparison studies, conclusive gender-related differences cannot be drawn. This systematic review underscores the complex interplay between AAS use, body image, eating behavior, and physical activity, emphasizing the necessity for further research to develop targeted interventions for diverse populations, addressing AAS-related concerns and promoting overall well-being.

Selective Androgen Receptor Modulators Leading to Liver Injury: A Case Report

Selective androgen receptor modulators (SARMs) have gained popularity for their alleged ability to selectively target androgen receptors, potentially offering muscle-building benefits with fewer side effects than traditional steroids. However, the safety profile of SARMs, including RAD-140, is not fully understood. This case report presents a 29-year-old male who developed liver injury after taking RAD-140. The patient experienced jaundice and elevated liver enzymes after three months of RAD-140 use. A liver ultrasound revealed hepatic steatosis and a hyperechoic lesion. Symptoms resolved after discontinuing RAD-140. Similar cases of liver injury associated with RAD-140 have been reported, highlighting the potential hepatotoxicity of this SARM. Discontinuation of RAD-140 appears to reverse liver injury, but the long-term effects and risks of SARM use remain unclear. This case highlights the need for caution and monitoring when considering SARMs for performance enhancement.

Androgen abuse: Risks and adverse effects in men

Androgens, formerly known as anabolic-androgenic steroids, mimic the effects of testosterone and are being increasingly abused for nonmedical purposes such as body and performance enhancement. Androgen abuse is associated with increased mortality, and multisystem adverse effects have been reported, including cardiovascular toxicity, infertility, hypogonadism, hepatotoxicity, and mental health disorders. Men may present with the negative health consequences of androgen abuse even despite cessation for a number of years. There is frequently a reluctance to disclose androgen abuse, and substances are often sourced from the black market, which is not regulated and where the products sold may be counterfeit. All men should be encouraged to stop androgen abuse. Managing associated adverse effects will be organ-specific and is complex due to physical and neuropsychiatric symptoms, substance dependence, and high rates of relapse. Given the broad reach and prolonged adverse effects of androgen abuse, clinicians across medical specialties should have an awareness of androgen abuse, its increasing prevalence, and the harms it poses to men and their families. This narrative review aims to summarize the adverse effects and risks associated with androgen abuse.

Illegal Use of Testosterone and Other Anabolic-Androgenic Steroids in the Population of Amateur Athletes in Wrocław, Poland-An Unfavorable Lifestyle Trend in the Population of Men of Reproductive Age

Background: One factor that may negatively impact male reproductive health is the illegal use of testosterone and anabolic-androgenic steroids. This study aimed to evaluate the prevalence of testosterone use in recreational athletes, as well as factors associated with its use, and to determine the profile of a person using testosterone. Methods: A cross-sectional analysis of data from an anonymous, online questionnaire of men recruited from gyms, randomly selected in Wrocław, Poland, has been performed. The minimal sample size was evaluated with the univariate logistic regression model. The association between testosterone use and other factors was also evaluated with the univariate logistic regression model. Results: A total of 35% of respondents used testosterone. The main purposes of testosterone use were the improvement of training effects and the improvement of body shape. The respondents most likely to use testosterone and other anabolic-androgenic steroids were men aged 26-35, whose earnings were at the level of the middle class or higher, who were married, had children, had training experience of at least 6 months, exercised at least once a week, took part in weightlifting competitions, were managers in a corporation or enterprise, or were self-employed. Most of the people using testosterone had self-treated side effects. Conclusions: The profile of the person most likely to use testosterone corresponds to the characteristics of men in optimal socio-demographic conditions for reproduction. These results indicate that this is a significant social problem that may impact male reproductive health.

Muscle dysmorphia: an under-recognised aspect of body dissatisfaction in men

Although men and women both experience eating disorders such as anorexia nervosa and bulimia nervosa, there are differences in the way their eating disorder may present. Body dissatisfaction or body dysmorphia in men may be more related to a drive for muscularity as opposed to thinness. Muscle dysmorphic disorder (also known as muscle dysmorphia) is a form or subtype of body dysmorphia that is characterised by an extreme desire for muscularity and a preoccupation with the idea that one's physique is too small or not sufficiently muscular. It is more common in men than women and is associated with body image distortion, excessive exercise routines, muscularity-orientated disordered eating and the use of appearance- and performance-enhancing drugs such as anabolic androgenic steroids. Risk factors for muscle dysmorphic disorder include social pressure (including to conform to gender stereotypes) and low self-esteem. The condition has negative psychological, physical, relational and financial effects. Nurses can play a role in health promotion as well as in the assessment, care and referral of men with muscle dysmorphic disorder.

Testosterone: A Review for Orthopaedic Surgeons

» Testosterone replacement treatment (TRT) and anabolic androgenic steroid (AAS) use is common and possibly increasing.» Diagnosing and treating hypogonadism in men is controversial.» Hypogonadism and the use of AASs seem to have a detrimental effect on the musculoskeletal system. The current literature on TRT and the musculoskeletal system shows an increased risk of tendon injury.» There may be a role for testosterone supplementation in the postoperative period.

Assessment of Anabolic Androgenic Steroids Use Among Professional CrossFit® Athletes: Motives, Perception, and Safety

BACKGROUND

Anabolic androgenic steroids (AAS) are traditionally used for the treatment/control of various diseases; however, they are being used for non-therapeutic and indiscriminate purposes to enhance sports performance and physical appearance. This study aimed to assess the prevalence and associated factors of AAS use among professional CrossFit® competitors.

METHODS

We conducted an observational cross-sectional survey in which an anonymous questionnaire was applied to professional CrossFit® athletes.

RESULTS

The prevalence of AAS usage was 33.3%. Most users were male (74.2%), aged between 30 and 39 years (51.6%), with completed higher education (83.9%), and had been training for more than 5 years (77.4%); the primary motivation for AAS use was performance enhancement (77.4%). Individuals who were older (p < 0.05) and more experienced in competitions (p < 0.01) are more likely to use AAS. Testosterone was the most employed AAS (71.0%); CrossFit® athletes typically used an average of 2 different AAS. The majority of users had notably sought advice from a physician (74.2%), and AAS were acquired from either drugstores (80.6%) or through illicit channels (29.0%). Moreover, 61.3% of AAS users reported experiencing adverse effects.

CONCLUSIONS

Our results demonstrated a higher prevalence of AAS users among professional competitors in CrossFit® compared to the general population; older age and greater experience in official competitions were decisive factors for a greater inclination toward AAS use. A significant percentage of athletes seek drugs through illegal channels. Despite the majority of users experiencing adverse effects, athletes report satisfaction with use, believing that the benefits still outweigh the drawbacks.

Impact of androgenic anabolic steroid use on cardiovascular and mental health in Danish recreational athletes: protocol for a nationwide cross-sectional cohort study as a part of the Fitness Doping in Denmark (FIDO-DK) study

INTRODUCTION

The use of androgenic anabolic steroids (AASs) among recreational athletes is steadily increasing. However, knowledge regarding the potentially harmful effects of AAS primarily originates from case reports and small observational studies. This large-scale study aims to investigate the impact of AAS use on vascular plaque formation, preclinical coronary disease, cardiac function, circulating cardiovascular risk markers, quality of life (QoL) and mental health in a broad population of illicit AAS users.

METHODS AND ANALYSES

A nationwide cross-sectional cohort study including a diverse population of men and women aged ≥18 years, with current or previous illicit AAS use for at least 3 months. Conducted at Odense University Hospital, Denmark, the study comprises two parts. In part A (the pilot study), 120 recreational athletes with an AAS history will be compared with a sex-matched and age-matched control population of 60 recreational athletes with no previous AAS use. Cardiovascular outcomes include examination of non-calcified coronary plaque volume and calcium score using coronary CT angiography, myocardial structure and function via echocardiography, and assessing carotid and femoral artery plaques using ultrasonography. Retinal microvascular status is evaluated through fundus photography. Cardiovascular risk markers are measured in blood. Mental health outcomes include health-related QoL, interpersonal difficulties, body image concerns, aggression dimensions, anxiety symptoms, depressive severity and cognitive function assessed through validated questionnaires. The findings of our comprehensive study will be used to compose a less intensive investigatory cohort study of cardiovascular and mental health (part B) involving a larger group of recreational athletes with a history of illicit AAS use.

ETHICS AND DISSEMINATION

The study received approval from the Regional Committee on Health Research Ethics for Southern Denmark (S-20210078) and the Danish Data Protection Agency (21/28259). All participants will provide signed informed consent. Research outcomes will be disseminated through peer-reviewed journals and scientific conferences.

TRIAL REGISTRATION NUMBER

NCT05178537.

The decanoate esters of nandrolone, testosterone, and trenbolone induce steroid specific memory impairment and somatic effects in the male rat

Long-term use of anabolic androgenic steroids (AAS) in supratherapeutic doses is associated with severe adverse effects, including physical, mental, and behavioral alterations. When used for recreational purposes several AAS are often combined, and in scientific studies of the physiological impact of AAS either a single compound or a cocktail of several steroids is often used. Because of this, steroid-specific effects have been difficult to define and are not fully elucidated. The present study used male Wistar rats to evaluate potential somatic and behavioral effects of three different AAS; the decanoate esters of nandrolone, testosterone, and trenbolone. The rats were exposed to 15 mg/kg of nandrolone decanoate, testosterone decanoate, or trenbolone decanoate every third day for 24 days. Body weight gain and organ weights (thymus, liver, kidney, testis, and heart) were measured together with the corticosterone plasma levels. Behavioral effects were studied in the novel object recognition-test (NOR-test) and the multivariate concentric square field-test (MCSF-test). The results conclude that nandrolone decanoate, but neither testosterone decanoate nor trenbolone decanoate, caused impaired recognition memory in the NOR-test, indicating an altered cognitive function. The behavioral profile and stress hormone level of the rats were not affected by the AAS treatments. Furthermore, the study revealed diverse AAS-induced somatic effects i.e., reduced body weight development and changes in organ weights. Of the three AAS included in the study, nandrolone decanoate was identified to cause the most prominent impact on the male rat, as it affected body weight development, the weights of multiple organs, and caused an impaired memory function.

Abusive use of anabolic androgenic steroids, male sexual dysfunction and infertility: an updated review

The evolving prevalence of anabolic androgenic steroids (AAS) abuse among nonathletes is alarming because of the known harm to an individual's health. Among the adverse effects of AAS abuse, male infertility and sexual dysfunction have been often reported in the literature, but little is known regarding its actual prevalence, possible underpinning mechanisms, and potential treatments either during or post-AAS usage. Thus, the current narrative review summarizes the state-of-art regarding the effects of AAS on male fertility and sexual function. Evidence was gathered from the latest reviews and recent original studies, specifically from prospective cohorts and clinical trials, ultimately resulting in five main topics of discussion. First, AAS usage is briefly characterized by its historical background, main physiological mechanisms, and the most frequently used AAS substances. Second, data on the prevalence of AAS-induced male infertility and sexual dysfunction are described. Third, some new insights on possible underpinning mechanisms of AAS-induced male infertility and sexual dysfunction are thoroughly discussed, with particular attention to histological data derived from animal models and the latest insights from prospective cohorts in humans. Fourth, the potential treatments during and after the AAS usage are presented, highlighting the odds of resolving male infertility and sexual dysfunction. Fifth, future directions on this topic are discussed, focusing on the methodological robustness of scientific studies.

Unmasking Distorted Reflections: Exploring Body Image, Alcohol, and Drug Use in Nighttime Entertainment Districts

Background: Violence within nighttime entertainment districts (NEDs) has been blamed on problematic masculinity and has predominantly been attributed to excessive alcohol intake and steroid use in men. In this report we conducted two studies to: (1) ascertain whether researchers could act as third-party raters of body weight and muscle mass in NED patrons; and (2) to examine the relationship between body self-image, inebriation, alcohol preloading behaviors and drug use in the NEDs. Methods: Study 1 employed an observational approach to establish inter-rater reliability for ratings of muscle mass and weight. In Study 2 data (n = 2,745) were collected through breathalyzing and questionnaires to examine individuals' self-image and drinking and drug-taking behaviors. Results: Participants' self-ratings of muscle and weight significantly differed from researchers' ratings, with males perceiving themselves as less muscular and females perceiving themselves as heavier. Perceived weight and muscle size did not relate to alcohol levels, but an interaction was found for female steroid users who perceived themselves as less muscular. Conclusions: Findings indicated a distortion in participants' perceived body image, with a desire for muscularity among both males and females. These results underscore the complex interplay between self-perception, societal ideals, and drug use in young NED patrons.

Understanding the variation in exercise responses to guide personalized physical activity prescriptions

Understanding the factors that contribute to exercise response variation is the first step in achieving the goal of developing personalized exercise prescriptions. This review discusses the key molecular and other mechanistic factors, both extrinsic and intrinsic, that influence exercise responses and health outcomes. Extrinsic characteristics include the timing and dose of exercise, circadian rhythms, sleep habits, dietary interactions, and medication use, whereas intrinsic factors such as sex, age, hormonal status, race/ethnicity, and genetics are also integral. The molecular transducers of exercise (i.e., genomic/epigenomic, proteomic/post-translational, transcriptomic, metabolic/metabolomic, and lipidomic elements) are considered with respect to variability in physiological and health outcomes. Finally, this review highlights the current challenges that impede our ability to develop effective personalized exercise prescriptions. The Molecular Transducers of Physical Activity Consortium (MoTrPAC) aims to fill significant gaps in the understanding of exercise response variability, yet further investigations are needed to address additional health outcomes across all populations.

Supraphysiological testosterone levels from anabolic steroid use and reduced sensitivity to negative facial expressions in men

RATIONALE

Anabolic-androgenic steroids (AAS) are used to improve physical performance and appearance, but have been associated with deficits in social cognitive functioning. Approximately 30% of people who use AAS develop a dependence, increasing the risk for undesired effects.

OBJECTIVES

To assess the relationship between AAS use (current/previous), AAS dependence, and the ability to recognize emotional facial expressions, and investigate the potential mediating role of hormone levels.

METHODS

In total 156 male weightlifters, including those with current (n = 45) or previous (n = 34) AAS use and never-using controls (n = 77), completed a facial Emotion Recognition Task (ERT). Participants were presented with faces expressing one out of six emotions (sadness, happiness, fear, anger, disgust, and surprise) and were instructed to indicate which of the six emotions each face displayed. ERT accuracy and response time were recorded and evaluated for association with AAS use status, AAS dependence, and serum reproductive hormone levels. Mediation models were used to evaluate the mediating role of androgens in the relationship between AAS use and ERT performance.

RESULTS

Compared to never-using controls, men currently using AAS exhibited lower recognition accuracy for facial emotional expressions, particularly anger (Cohen's d = -0.57, pFDR = 0.03) and disgust (d = -0.51, pFDR = 0.05). Those with AAS dependence (n = 47) demonstrated worse recognition of fear relative to men without dependence (d = 0.58, p = 0.03). Recognition of disgust was negatively correlated with serum free testosterone index (FTI); however, FTI did not significantly mediate the association between AAS use and recognition of disgust.

CONCLUSIONS

Our findings demonstrate impaired facial emotion recognition among men currently using AAS compared to controls. While further studies are needed to investigate potential mechanisms, our analysis did not support a simple mediation effect of serum FTI.

The Association Between the Nonmedical use of Anabolic-Androgenic Steroids and Interpersonal Violence: A Meta-Analysis

The nonmedical use of anabolic-androgenic steroids (AAS) by athletes and the general population is a public health concern. One particular concern relates to the link between AAS use and violence. Although there is a growing body of research on the association between AAS and violence, results as to what the relationship is seem to be mixed. The aim of this meta-analysis is to improve our understanding of what the current evidence base indicates regarding the relationship between the use of AAS and interpersonal violence. In total, 14 studies with a total of 16 samples met the inclusion criteria, comprising a total sample size of 137,055 participants. The findings show that there is a significant association between AAS use and interpersonal violence (r = .21 [95% confidence intervals (CI): 0.15, 0.27], p < .00001), although small. It is however unclear what the direction of this relationship is as almost all studies failed to demonstrate whether AAS use occurred prior or subsequent to the violent behavior. Risk of bias for most studies was moderate or high. Three potential moderators, AAS use via self-report or testing, interpersonal violence via self-report or criminal records of violent behavior, and proportion of males, were nonsignificant. Although a meta-analytic relationship between AAS use and interpersonal violence was found, it is unclear to what extent AAS causes violent acts. We need to carefully consider the role of mediating factors, and that the relationship between the two could be part of a broader context as opposed to AAS being the cause of violence.

Androgenic steroid excess in women

Excessive use of anabolic-androgenic steroids (AAS) in sport occurs among professional athletes but increasingly also in amateurs. Prevalence of steroid use has been on the rise for a number of years. While the practice involves mostly men, it also occurs in women with an estimated prevalence of 1.6%. Since 2014, a 'steroid passport' has operated for sports people in competition that is based on longitudinal urinary and blood steroid levels, measured by liquid chromatography and mass spectrometry. Androgen excess stimulates muscle growth and improves muscle performance. However, their consumption carries numerous side effects, including myocardial hypertrophy; altered lipid metabolism and pro-thrombotic effects. The excess of AAS is associated with increased risk of atherosclerosis and cardiovascular events. Data for their effects in women is lacking. Perturbations of the menstrual cycle are common in female athletes, with spaniomenorrhea and even amenorrhea. This can be a consequence of gonadotropin insufficiency due to negative caloric balance, but may also be due to endogenous or exogenous hyperandrogenism. The use of AAS is probably underestimated as a public health issue, particularly in women, and thus presents a prevention challenge for healthcare professionals.

Exploring the prevalence of anabolic steroid use among men and women resistance training practitioners after the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic has had a significant impact on individual health and fitness routines globally. Resistance training, in particular, has become increasingly popular among men and women looking to maintain or improve their physical fitness during the pandemic. However, using Anabolic Steroids (AS) for performance enhancement in resistance training has known adverse effects. Thus, this study aimed to explore the prevalence of AS use among men and women resistance training practitioners after the COVID-19 pandemic.

METHODS

A cross-sectional survey was conducted among 3,603 resistance training practitioners (1,855 men and 1,748 women) in various geographical locations impacted by COVID-19. The participants were asked to complete self-administered questionnaires, which included questions regarding demographic information, training habits, and current or prior usage of AS. The data were analyzed using SPSS statistical software and the chi-square method, with a significance level of (P < 0.05).

RESULTS

A total of 3603 men and women resistance training practitioners completed the survey. In the study, 53.05% of men and 41.99% of women used anabolic and androgenic steroids. Of those men who used steroids, 29.47% used Testosterone, while 31.20% of women used Winstrol. Additionally, 50.30% of men used steroids via injection, while 49.05% of women used them orally. According to the study, 49.99% of the participants had 6 to 12 months of experience with resistance training, and 64.25% of them underwent three training sessions per week. The analysis using the χ2 test did not reveal any significant difference between men and women in terms of duration of bodybuilding, frequency per week, and engagement in other activities.

CONCLUSION

This study shows that a significant proportion of men and women resistance training practitioners used AS, particularly among young adults with limited training experience. Thus, there is a need for targeted education and awareness campaigns to address the hazards of AS use and promote healthy training habits during the COVID-19 pandemic.

Detection of anabolic-androgenic steroids in e-cigarettes seized from prisons: A case study

The administration of new psychoactive substances (NPS), in particular synthetic cannabinoid receptor agonists (SCRAs), via e-cigarettes, within prison settings has been well publicized. This study provides an overview of five e-cigarette case samples seized from Scottish prisons between May 2022 and July 2023 where the anabolic-androgenic steroids (AASs) mestanolone and oxandrolone were identified following gas chromatography-mass spectrometry (GC-MS) analysis. These e-cigarette samples represented 2.9% of all samples containing e-cigarette cartridges (n = 170) and 9.4% of all samples found to contain AASs (n = 53) seized during the same time period. The AASs were detected in combination with other drugs, including cocaine, Δ9-tetrahydrocannabinol (Δ9-THC), SCRAs and nicotine. This represents a new and novel route of administration for AASs.

Purinergic signaling influences the neuroinflammatory outcomes of a testosterone-derived synthetic in female rats: Resistance training protective effects on brain health

Physical exercise is recognized as a non-pharmacological approach to treat and protect against several neuroinflammatory conditions and thus to prevent brain disorders. However, the interest in ergogenic resources by athletes and bodybuilding practitioners is widespread and on the rise. These substances shorten the process of performance gain and improve aesthetics, having led to the prominent use and abuse of hormones in the past years. Recent evidence has shown that the purinergic system, composed of adenine nucleotides, nucleosides, enzymes, and receptors, participates in a wide range of processes within the brain, such as neuroinflammation, neuromodulation, and cellular communication. Here, we investigated the effects of the anabolic androgenic steroid (AAS) testosterone (TES) at a dose of 70 mg/kg/week in female rats and the neuroprotective effect of resistance exercise related to the purinergic system and oxidative stress parameters. Our findings showed a decrease in ATP and ADO hydrolysis in treated and trained animals. Furthermore, there was an increase in the density of purinoceptors (P2X7 and A2A) and inflammatory markers (IBA-1, NRLP3, CASP-1, IL-1β, and IL-6) in the cerebral cortex of animals that received AAS. On the other hand, exercise reversed neuroinflammatory parameters such as IBA-1, NLRP3, CASP-1, and IL-1β and improved antioxidant response and anti-inflammatory IL-10 cytokine levels. Overall, this study shows that the use of TES without indication or prescription disrupts brain homeostasis, as demonstrated by the increase in neuroinflammation, and that the practice of exercise can protect brain health.

Hypertension in Athletes: Clinical Implications and Management Strategies

Hypertension is a leading cardiovascular risk factor in athletes. Sport-specific behaviors including nonsteroidal anti-inflammatory use, stimulant use, and unhealthy diets may promote hypertension among athletes. Strength-trained athletes may be more susceptible to hypertension than endurance-trained athletes, although this may, in part, be due to body size differences and the more potent antihypertensive effects of aerobic exercise. With confirmed hypertension, young athletes require secondary hypertension evaluation while older athletes require full cardiovascular risk stratification. Calcium channel blockers and renin-angiotensin-system inhibitors are often preferred pharmacotherapy agents. Further selection of antihypertensives must include consideration of potential side effects and legality in specific sports.
