Abstract
OBJECTIVES To assess the prevalence of anabolic steroid use and the level of knowledge on anabolic steroids among the male athletes in Al Madina Al Munawara, Saudi Arabia. METHODS A cross-sectional study was conducted on male athletes randomly selected from the private athletic centers in Al Madina Al Munawara over 5 months. Data were collected from all participants using a self-administered anonymous questionnaire with 33 questions. The questionnaire covered the socio-demographic characteristics of the participants, and their knowledge, attitudes, and use of anabolic steroids. RESULTS Of the 150 male athletes surveyed, 121 completed the questionnaire (response rate: 80.6%). Over half were aged between 18 and 23 years (56.2%) and were single (79.3%). Thirty-two percent reported using anabolic steroids, mainly to increase muscle mass, following coaches' advice (46.1%). Key sources included the internet (30.7%), coaches (30%), and friends (27.9%), and non-healthcare professionals. The top motivations were price, coach's/physician's advice, and availability. The perceived benefits included increased muscle mass, strength, and endurance, while the perceived adverse effects included kidney/liver damage and sexual problems. CONCLUSION One-third of the male athletes surveyed used anabolic steroids, influenced by accessibility and social contact, rather than healthcare guidance. This highlights the need for greater awareness of the long-term health risks, ideally through education provided by sports medicine specialists.

Involvement of porcine and human carbonyl reductases in the metabolism of epiandrosterone, 11-oxygenated steroids, neurosteroids, and corticosteroids. J Steroid Biochem Mol Biol 2024; 243:106574. [PMID: 38945307 DOI: 10.1016/j.jsbmb.2024.106574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/11/2024] [Accepted: 06/24/2024] [Indexed: 07/02/2024]
Abstract
Porcine carbonyl reductases (pCBR1 and pCBR-N1) and aldo-keto reductases (pAKR1C1 and pAKR1C4) exhibit hydroxysteroid dehydrogenase (HSD) activity. However, their roles in the metabolism of porcine-specific androgens (19-nortestosterone and epiandrosterone), 11-oxygenated androgens, neurosteroids, and corticosteroids remain unclear. Here, we compared the steroid specificity of the four recombinant enzymes by kinetic and product analyses. In C18/C19-steroids,11-keto- and 11β-hydroxy-5α-androstane-3,17-diones were reduced by all the enzymes, whereas 5α-dihydronandrolone (19-nortestosterone metabolite) and 11-ketodihydrotestosterone were reduced by pCBR1, pCBR-N1, and pAKR1C1, of which pCBR1 exhibited the lowest (submicromolar) Km values. Product analysis showed that pCBR1 and pCBR-N1 function as 3α/β-HSDs, in contrast to pAKR1C1 and pAKR1C4 (acting as 3β-HSD and 3α-HSD, respectively). Additionally, 17β-HSD activity was observed in pCBR1 and pCBR-N1 (toward epiandrosterone and its 11-oxygenated derivatives) and in pAKR1C1 (toward androsterone, 4-androstene-3,17-dione and their 11-oxygenated derivatives). The four enzymes also showed different substrate specificity for 3-keto-5α/β-dihydro-C21-steroids, including GABAergic neurosteroid precursors and corticosteroid metabolites. 5β-Dihydroprogesterone was reduced by all the enzymes, whereas 5α-dihydroprogesterone was reduced only by pCBR1, and 5α/β-dihydrodeoxycorticosterones by pCBR1 and pCBR-N1. The two pCBRs also reduced the 5α/β-dihydro-metabolites of cortisol, 11-deoxycortisol, cortisone, and corticosterone. pCBR1 exhibited lower Km values (0.3-2.9 μM) for the 3-keto-C21-steroids than pCBR-N1 (Km=10-36 μM). The reduced products of the 3-keto-C21-steroids by pCBR1 and pCBR-N1 were their 3α-hydroxy-metabolites. Finally, we found that human CBR1 has similar substrate specificity for the C18/C19/C21-steroids to pCBR-N1. Based on these results, it was concluded that porcine and human CBRs can be involved in the metabolism of the aforementioned steroids as 3α/β,17β-HSDs.

Abstract
The study aimed to show the potential clinical application of supplements used among sportsmen for patients suffering from Intensive Care Unit-acquired Weakness (ICUAW) treatment. ICUAW is a common complication affecting approximately 40% of critically ill patients, often leading to long-term functional disability. ICUAW comprises critical illness polyneuropathy, critical illness myopathy, or a combination of both, such as critical illness polyneuromyopathy. Muscle degeneration begins shortly after the initiation of mechanical ventilation and persists post-ICU discharge until proteolysis and autophagy processes normalize. Several factors, including prolonged bedrest and muscle electrical silencing, contribute to muscle weakness, resulting from an imbalance between protein degradation and synthesis. ICUAW is associated with tissue hypoxia, oxidative stress, insulin resistance, reduced glucose uptake, lower adenosine triphosphate (ATP) formation, mitochondrial dysfunction, and increased free-radical production. Several well-studied dietary supplements and pharmaceuticals commonly used by athletes are proven to prevent the aforementioned mechanisms or aid in muscle building, regeneration, and maintenance. While there is no standardized treatment to prevent the occurrence of ICUAW, nutritional interventions have demonstrated the potential for its mitigation. The use of ergogenic substances, popular among muscle-building sociates, may offer potential benefits in preventing muscle loss and aiding recovery based on their work mechanisms.

Pinto TG, Malacarne IT, Takeshita WM, de Barros Viana M, Renno ACM, Ribeiro DA. Is genotoxicity a suitable biomarker for monitoring anabolic-androgenic steroids exposure in vivo? A systematic review and meta-analysis. J Appl Toxicol 2024. [PMID: 38840431 DOI: 10.1002/jat.4656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/22/2024] [Accepted: 05/24/2024] [Indexed: 06/07/2024]
Abstract
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.

Abstract
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.

The decanoate esters of nandrolone, testosterone, and trenbolone induce steroid specific memory impairment and somatic effects in the male rat. Horm Behav 2024; 161:105501.

Abstract
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.

Abstract
Stanozolol shows promise as an anabolic and anti-catabolic agent for treating degenerative joint disease (DJD). This study assessed the clinical efficacy of a single intra-articular stanozolol injection in canine knees with DJD and its correlation with serum IL-1β levels. Thirty dogs (n = 30) were divided into a control group (CG, n = 10) and a study group (SG, n = 20) with DJD. Pain levels were assessed using the Brown query, and radiographs were taken at T0 and T3. IL-1β levels were quantified via ELISA. Apart from 2 patients, all showed reduced pain intensity, with 15 patients showing improvement at T1 and 3 patients at T2. A positive correlation (r = 0.84; p < 0.01) was found between pain level and IL-1β in 15 patients. No systemic effects were observed. Most patients (18/20) experienced reduced pain. This pilot study suggests stanozolol's potential in managing DJD in dogs. Further research is warranted to validate these findings and understand stanozolol's mechanism in DJD treatment.

Abstract
Maca (Lepidium meyenii) is a plant that grows in the central Andes region of Peru, and it has been reported to have various bioactive functions, such as improving or preventing osteoporosis, sexual dysfunction, and memory impairment. In this study, maca roots of various colors (yellow, red, or black) were extracted using different polar solvents (PE, HEX, or BuOH) to compare their effects on muscle differentiation. Among them, the red maca lipophilic extract, which showed the most effectiveness, was chosen for further investigation. Our results show that RMLE enhances muscle differentiation by inducing MyoD-E2A heterodimerization through the activation of the AKT/p38 pathway. Additionally, RMLE attenuated dexamethasone-induced muscle atrophy by inhibiting nuclear translocation of FoxO3a and expression of E3-ligase (MAFbx and MURF1) in vitro and in vivo. Therefore, based on these results suggest that lipophilic extract of maca, which can abundantly contain nonpolar compounds, macamides, can enhance the functional properties of maca in alleviating muscle homeostasis.

Abstract
OBJECTIVE This systematic review aims to evaluate the optimal treatment for male infertility resulting from Anabolic Androgenic Steroids (AAS) abuse. METHODS A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies that compared different protocols for the recovery of spermatogenesis in patients after AAS use were included. RESULTS 13 studies investigating different protocols to restore spermatogenesis in patients with AAS abuse met the inclusion criteria. The available agents that showed restoration of spermatogenesis include injectable gonadotropins, selective estrogen receptor modulators, and aromatase inhibitors, but their use is still poorly described in the literature. CONCLUSIONS Clinicians need to be aware of the detrimental effects of AAS on spermatogenesis. AAS-associated infertility may be reversible, but sperm production may take over a year to normalize. Both conservative and aggressive treatment can boost spermatogenesis with positive results. Further understanding of male reproductive endocrinology and high-quality data on the field of restoration of spermatogenesis after AAS abuse are warranted.

As novel substances, short time windows, and limits of detection increasingly challenge direct methods of doping detection in sports, indirect tools inevitably take a greater role in the fight against it. One such tool is the athlete biological passport (ABP) - a longitudinal profiling of the measured haematological and biochemical biomarkers, combined with calculated scores, against the background of epidemiological data crucial for doping detection. In both of its modules, haematological and steroidal, ABP parameters are analysed with the Bayesian adaptive model, which individualises reference and cut-off values to improve its sensitivity. It takes into account the confounding factors with proven and potential influence on the biomarkers, such as race and altitude exposure. The ABP has already changed the fight against doping, but its importance will further grow with the new modules (e.g., endocrinological), parameters (e.g., plasma volume-independent parameters), and complementing indirect methods (e.g., transcriptomic).

Purinergic signaling influences the neuroinflammatory outcomes of a testosterone-derived synthetic in female rats: Resistance training protective effects on brain health. Steroids 2024; 203:109352.

Abstract
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.

Abstract
In the wake of the Novel Coronavirus arrival, the world witnessed the fragility of healthcare systems and the resilience of healthcare workers who stood on the front lines. SARS-CoV-2, also known as COVID-19 or severe acute respiratory syndrome, first appeared in China in December 2019. The infection quickly spread across the nation and the world. All countries severely restricted social interaction to stop the virus's transmission, impacting all sporting, social, and recreational activities. Anabolic androgenic steroids (AASs) are frequently used illegally to enhance strength and physical attractiveness. However, they could hurt immune system health. Much research hasn't been done yet on the connection between Covid-19 and AASs. Synthetic testosterone analogs known as anabolic androgenic steroids (AASs) can have an immune-system-altering effect. Sportspeople and bodybuilders are vulnerable to AAS abuse. Governmental reactions to the coronavirus infection issue over the last year have drawn much attention and discussion regarding public services, the experience and lessons learned from different limitations, and strategies for dealing with potential future pandemics. Using AAS has the potential to cause a variety of adverse reactions, including cardiovascular issues (including high blood pressure, heart disease, and blood clots), liver damage, renal failure, mood swings, aggressiveness, and psychiatric disorders. Individuals already suffering from severe respiratory conditions like COVID-19 may have these risks increased. This review mainly highlights the anabolic androgen steroids use and its unseen effects on coronavirus patients and gymnastics.

Abstract
Background A growing number of athletes are using synthetic anabolic-androgenic steroids (AAS), comprised of testosterone and other derivatives, to enhance athletic performance and muscle mass. Over the years, numerous reports elucidated the side effects of the illegal use of AAS, such as infertility, and liver disorders. The effect of AAS on the hepatic and reproductive systems in Saudi athletes has not yet been studied. Therefore, this study examined the liver function and sex hormone parameters of AAS users as compared to non-users. Methods Fasting blood samples were collected from 16 male Saudi athletes, 10 AAS-users (cases) and 6 non-users (controls) to measure liver function tests (ALT, AST, GGT, ALP, total protein, albumin, direct and total bilirubin) and muscle enzymes (CK, LDH), Fertility hormones (LH, FSH, total testosterone, estradiol, and prolactin) were included also. Furthermore, a self-reported questionnaire was obtained to identify the type of AAS used, the dosage, and the length of the course before sample collection. Results The results show a statistically significant increase in ALT (P < 0.001), AST (P < 0.001), CK (P < 0.05), and a significant decrease (P < 0.05) in albumin (P < 0.001) and total bilirubin levels (P < 0.01) in AAS-users. Total testosterone increased significantly among AAS (P < 0.05), along with a significant decrease in LH (P < 0.01), and FSH (P < 0.001) levels, while serum prolactin and estradiol levels were significantly increased (P < 0.05). Conclusion AAS can enhance physical performance and appearance, its potential adverse effects on the hepatic and reproductive systems necessitate careful consideration. Our research demonstrates an increase in the liver-specific enzyme ALT in AAS users relative to non-users and the possibility that short-term AAS usage increases the risk of liver injury.

Abstract
The use of androgenic-anabolic steroids (AASs) has increased in recent years, especially among athletes, due to their effect on body shape and performance. These agents could have serious side effects on this highly susceptible population, which tends to use these substances frequently to promote muscle growth and physical performance. Therefore, this study aimed to evaluate the knowledge and attitudes toward the use of anabolic androgenic steroids among physical education university students in Palestine. A cross-sectional study of physical education students from November 2020 to January 2021 was conducted using an electronic questionnaire. The main outcome was to measure the level of knowledge and use of the AAS. A total of 380 students were included. The mean age of the students was 21 years (SD = 4.2), and the study participants were distributed almost equally according to sex. Approximately a quarter of the students were smokers. Eighty percent (80%) of the study participants were from the West Bank, while the remaining 20% were from Jerusalem and 48 territories. Furthermore, most of the students lived with their families; half lived in cities, approximately 152 (40%) lived in villages, and only 29 (8%) lived in camps. The average level of knowledge of the AAS was 2.95 out of 8 (37/100), with a median of three. Furthermore, only 36 (10%) of the participants had satisfactory knowledge, scoring 80% or more. Regarding the use of AAS, 11 (2.9%) participants, all males, confirmed that they were currently using AAS. Additionally, approximately 28 (7%) had previously used them, while 30 (8%) planned to try them in the future. Overall, 221 (58%) patients were confirmed to use vitamins and minerals. Our study showed that most of the participants had a substantial lack of information on the potential side effects of AAS, while the level of use was comparable with that of other populations.

Abstract
Methandienone is an anabolic-androgenic steroid that is prohibited in equine sports due to its potential performance enhancing properties. Metabolism and detection of methandienone in equine urine have been investigated comprehensively in literature; however, there is a limited knowledge about its metabolites in equine plasma and no information about its detection in equine hair. Following a multi-dose oral administration of methandienone to two Thoroughbred horses, 17-epimethandienone, methyltestosterone, two mono-hydroxylated, two di-hydroxylated and three 17α-methylandrostanetriol metabolites were detected in plasma. The majority of these were present as free analytes, whilst the mono-hydroxylated metabolites and one isomer of 17α-methylandrostanetriol were partially conjugated. Estimated peak concentrations of methandienone were 6,000 and 11,100 pg/ml; meanwhile, they were 25.4 and 40.5 pg/ml for methyltestosterone. The most abundant analyte in the post-administration plasma samples of both horses was the mono-hydroxylated metabolite; however, the parent compound provided the longest detection (up to 96 h). Screening analysis of hair enabled the detection of methandienone in mane hair samples only, for up to 3 months. Its mono- and di-hydroxylated metabolites were detected with greater peak responses for up to 6 months post-administration in both mane and tail samples, showing that these metabolites could be better analytical targets for hair analysis when administered orally. A follow-up methodology with an extensive wash procedure confirmed the presence of methandienone and its metabolites in a number of post-administration hair samples. Final wash samples were also analysed to assess the degree of internal incorporation (via bloodstream) against possible external deposition (via sweat/sebum).

Abstract
The use of anabolic androgenic steroids (AAS) for strength training and muscle building is a widespread practice among athletes and young individuals. Athletes and bodybuilders are using these substances for various purposes, such as enhancing muscle mass, strengthening their bodies, and enhancing their performances. AAS exert a wide range of physiological effects that result in the activation of central signaling, resulting in adverse effects. Moreover, excessive use of AAS which can be categorized as AAS abuse; is linked to biological and psychological pathologies, which can lead to mortality. Complications arising from steroid abuse involve both cellular and physiological complications. Cellular complications arise when activation of signaling proteins like mTOR, Akt, etc. leads to alteration in protein synthesis pathways, cell cycle, oxidative stress, and apoptosis, contributing to damage at the cellular level. Physiological complications are evident with cardiovascular pathologies, including an altered lipid profile, cardiac hypertrophy, hypogonadism after discontinuation of AAS, and modulation of GABA receptors in the brain, all contributed by the androgen receptor signaling. Clinical complications budding from these altered physiological processes lead to clinical effects like testicular dysfunction, acne, gynecomastia, and neuropsychiatric disorders. Despite potential therapeutic benefits, AAS use is prohibited by the World Anti-Doping Agency (WADA) due to concerns over adverse health effects. This review highlights the molecular mechanisms, physiological processes, and clinical complications arising from the excessive use of AAS among athletes.

Abstract
Bolasterone (7α,17α-dimethyltestosterone) and anabolic androgenic steroids are included in the World Anti-Doping Agency's Prohibited list of substances. This study aimed to evaluate the metabolism of bolasterone through in vitro experiments using rat liver microsomes and in vivo experiments using rat urine after oral administration. Urine samples were collected over a 168-h period. Bolasterone and its metabolites were detected by liquid chromatography coupled with a Q-Exactive Obitrap mass spectrometry (LC-HRMS). Ultimately 16 hydroxylated metabolites (M1-M16), one metabolite from the reduction of the 3-keto function and 4-ene (M17), and one glucuronic acid conjugated metabolite (M18) were detected. Metabolites M17 and M18 were confirmed by comparison with available reference or authentic standards. Metabolic modifications in the structure of the parent bolasterone result in different fragmentation patterns. Based on the sensitivity of the HRMS data, characteristic ions such as m/z 121.064 (C8 H9 O) generated from ring A of the mono-hydroxylated metabolites and 121.101 (C9 H13 ) generated from ring D of the di-hydroxylated metabolites were observed that helped differentiate between the obtained metabolites. The structures of fragment ions were tentatively proposed based on their fragmentation pathways, where the significant ions were correlated to the possible structural fragments. In conclusion, new metabolites of bolasterone were detected and characterized by the use of the full-scan and dd-MS/MS using LC-HRMS, and this data can be useful for providing metabolite information for the interpretation of mass spectra of anabolic bolasterone analogues for doping screening tests.

Abstract
PURPOSE To review the impact of testosterone and other androgenic-anabolic steroids (AASs) on male fertility, exploring potential drugs that can be used to preserve or restore male fertility upon AAS use or prior contact. METHODS A review was performed to provide a unifying clinical link between drugs used to preserve or restore male fertility (ie, clomiphene citrate, human chorionic gonadotropin, selective estrogen receptor modulators, recombinant luteinizing and follicle-stimulating hormones, and human menopausal gonadotrophin) in the context of AAS-induced infertility and related aspects. FINDINGS Human chorionic gonadotropin (125-500 IU every other day), clomiphene citrate (12.5-50 mg/d), recombinant luteinizing hormone (125-500 IU every other day), recombinant follicle-stimulating hormone (75-150 IU 1-3×/wk), and human menopausal gonadotrophin (75-150 IU 1-3×/wk) are promising early pharmacologic approaches to avert AAS-induced male infertility. Additionally, a full partner assessment is crucial to the success of a couple planning to have children. The partner's age and gynecopathies must be considered. Egg or sperm cryopreservation can also be alternatives for future fertility. Reinforcing AAS cessation is imperative to achieving better success in misusers. IMPLICATIONS The exponential increase in AAS misuse raises concerns about the impact on male fertility. This review suggests that gonadotropin analogs and selective androgen receptor modulators (clomiphene citrate) are viable approaches to early preserve or restore fertility in men on AAS use or with previous contact. However, proper standardization of doses and combinations is required and hence physicians should also be aware of patients' and partners' fertility.

Abstract
Nandrolone (Estr-4-en-17β-ol-3-one) is a derivative of testosterone and a naturally occurring anabolic-androgenic agent which belongs to the steroid group. Crystal structures of four short, medium and long esterified forms of nandrolone, including propionate, phenylpropionate, cypionate and undecanoate were determined using single-crystal X-ray diffraction. Crystal packing, supramolecular features and intermolecular interactions were described based on a quantitative and qualitative Hirshfeld surfaces analysis accompanied by evaluation of crystal energies and intermolecular interactions computation. Also, the solubility of the esters was investigated from a pharmaceutical perspective.

Results Highly competitive athletes consumed nutritional and mechanical aids more (OR = 1.96 CI 95% [1.28-2.9]; OR = 1.79 CI 95% [1.29-2.47]), while the use of psychological EAs decreased [OR = 1.66 95% CI (1.18-2.94); p = 0.001]. Male athletes [OR = 1.44 CI 95% (1.11-2.88)] and individual sports practitioners [OR = 1.78 CI 95% (1.02-3.11)] used nutritional aids more. Triathlon athletes had higher nutritional EA use, while soccer athletes had lower. Combat sports athletes had higher pharmacological EA use. Conclusion Athletes use nutritional and pharmacological aids more to improve performance and gain lean body mass. Mechanical aids were used for recovery and psychological aids for motivation. Self-prescription is common, especially for pharmacological aids.

Abstract
INTRODUCTION There are a variety of harms associated with anabolic-androgenic steroids (AAS), with some AAS associated with an increased risk profile for users. Despite potentially different risk profiles, these harms are seldom discussed with respect to specific compounds although recent ethnographic research has identified a need to do so. Specifically, myth has developed among users with trenbolone reportedly having more dramatic effects on individuals, with reports of aggression, violent behaviour and extreme mood disturbances, and this is reflected in extant literature. This paper aims to report on the narrative surrounding the use of trenbolone among AAS users. METHOD As part of a larger qualitative study, a number of AAS users were interviewed regarding their usage practices. A narrative emerged regarding the physical and psychological harms which accompanied their AAS use of which trenbolone played a central role (N = 16). RESULTS Of all the AAS, trenbolone was viewed as having the most deleterious consequences for those who used it. Users reported an extreme shift in risk profile for psychosocial harms, particularly increased aggression and violent behaviour, as well as impulsivity regulation issues. AAS-using peers and family members of users reported the readily observable effect of trenbolone. DISCUSSION AND CONCLUSIONS Users should be cognisant of the potential for significant harms and health-care providers working with this group may consider more focused screening strategies. Future policy decisions regarding AAS may wish to consider the pivotal role trenbolone plays in adverse outcomes for this unique group of substance users.

Abstract
Exposure to xenobiotics can adversely affect biochemical reactions, including hepatic bile acid synthesis. Bile acids are essential for dissolving lipophilic compounds in the hydrophilic environment of the gastrointestinal tract. The critical micellar concentration of bile acids depends on the Δ4-reduction stereochemistry, with the 3-oxo-5β-steroid-Δ4-dehydrogenase (AKR1D1) introducing the cis ring A/B conformation. Loss-of-function mutations in AKR1D1 cause hepatic cholestasis, which, if left untreated can progress into steatosis and liver cirrhosis. Furthermore, AKR1D1 is involved in clearing steroids with an A-ring Δ4-double bond. Here, we tested whether anabolic-androgenic steroids (AAS), often taken off-label at high doses, might inhibit AKR1D1, thereby potentially causing hepatotoxicity. A computational molecular model was established and used for virtual screening of the DrugBank database consisting of 2740 molecules, yielding mainly steroidal hits. Fourteen AAS were selected for in vitro evaluation, as such compounds can reach high hepatic concentrations in an abuse situation. Nandrolone, clostebol, methasterone, drostanolone, and methenolone inhibited to various extent the AKR1D1-mediated reduction of testosterone. Molecular modeling suggests that 9 out of 14 investigated AAS are competitive inhibitors. Moreover quantum mechanical calculations show that nadrolone and clostebol are substrates of AKR1D1 with different activation energy barriers for the hydrogen transfer from cofactor to the C5 position affecting their turnover. In this multidisciplinary approach, we established a molecular model of AKR1D1, identified several AAS as inhibitors, and described their binding mode. This approach may be applied to study other classes of inhibitors including non-steroidal compounds.

Abstract
Testosterone, many steroidal androgens, and nonsteroidal ligands that bind to androgen receptor and exert tissue-specific transcriptional activity (selective androgen receptor modulators [SARMs]) are being developed as function-promoting therapies to treat functional limitations associated with aging and chronic diseases. This narrative review describes preclinical studies, mechanisms, and randomized trials of testosterone, other androgens, and nonsteroidal SARMs. Sex differences in muscle mass and strength and empiric use of anabolic steroids by athletes to increase muscularity and athletic performance provide supportive evidence of testosterone's anabolic effects. In randomized trials, testosterone treatment increases lean body mass, muscle strength, leg power, aerobic capacity, and self-reported mobility. These anabolic effects have been reported in healthy men, hypogonadal men, older men with mobility limitation and chronic diseases, menopausal women, and HIV-infected women with weight loss. Testosterone has not consistently improved walking speed. Testosterone treatment increases volumetric and areal bone mineral density, and estimated bone strength; improves sexual desire, erectile function, and sexual activity; modestly improves depressive symptoms; and corrects unexplained anemia in older men with low testosterone levels. Prior studies have not been of sufficient size or duration to determine testosterone's cardiovascular and prostate safety. The efficacy of testosterone in reducing physical limitations, fractures, falls, progression to diabetes, and correcting late-onset persistent depressive disorder remains to be established. Strategies to translate androgen-induced muscle mass and strength gains into functional improvements are needed. Future studies should evaluate the efficacy of combined administration of testosterone (or a SARM) plus multidimensional functional exercise to induce neuromuscular adaptations required for meaningful functional improvements.

Abstract
The liver is the most common target organ in toxicology studies. The development of chemical structural alerts for identifying hepatotoxicity will play an important role in in silico model prediction and help strengthen the identification of analogs used in structure activity relationship (SAR)- based read-across. The aim of the current study is development of an SAR-based expert-system decision tree for screening of hepatotoxicants across a wide range of chemistry space and proposed modes of action for clustering of chemicals using defined core chemical categories based on receptor-binding or bioactivation. The decision tree is based on ∼ 1180 different chemicals that were reviewed for hepatotoxicity information. Knowledge of chemical receptor binding, metabolism and mechanistic information were used to group these chemicals into 16 different categories and 102 subcategories: four categories describe binders to 9 different receptors, 11 categories are associated with possible reactive metabolites (RMs) and there is one miscellaneous category. Each chemical subcategory has been associated with possible modes of action (MOAs) or similar key structural features. This decision tree can help to screen potential liver toxicants associated with core structural alerts of receptor binding and/or RMs and be used as a component of weight of evidence decisions based on SAR read-across, and to fill data gaps.

Abstract
INTRODUCTION Prior research has demonstrated that personality disorders and clinical psychiatric syndromes are common among users of anabolic-androgenic steroids (AAS). However, the prevalence, expression, and severity of psychopathology differ among AAS users and remain poorly understood. In this study, we examine the existence of potential clinically coherent psychopathology subgroups, using cluster procedures. METHODS A sample of 118 male AAS users and 97 weightlifting nonusers was assessed using the Millon Clinical Multiaxial Inventory-III (MCMI-III), measuring personality disorders and clinical syndromes. Group differences in MCMI-III scales were assessed using Wilcoxon-Mann-Whitney tests and Fisher's exact test. Agglomerative hierarchical clustering was used to identify clusters based on MCMI-III scale scores from the whole sample. RESULTS AAS users displayed significantly higher scores on all personality disorder (except narcissistic) and clinical syndrome scales compared to nonusing weightlifters. The clustering analysis found four separate clusters with different levels and patterns of psychopathology. The "no psychopathology" cluster was most common among nonusing weightlifters, while the three other clusters were more common among AAS users: "severe multipathology," "low multipathology," and "mild externalizing." The "severe multipathology" cluster was found almost exclusively among AAS users. AAS users also displayed the highest scores on drug and alcohol dependence syndromes. CONCLUSIONS AAS users in our sample demonstrated greater psychopathology than the nonusing weightlifters, with many exhibiting multipathology. This may pose a significant challenge to clinical care for AAS users, particularly as there appears to be significant variation in psychopathology in this population. Individual psychiatric profiles should be taken into consideration when providing treatment to this group. SIGNIFICANT OUTCOMES As a group, AAS users displayed markedly greater psychopathology than nonusing weightlifters. Multipathology was common among AAS users. Four different subgroups of personality profiles were identified with distinct patterns of pathology and severity. LIMITATIONS The cross-sectional nature of the study precludes inferences about causality. The study is limited by possible selection bias, as participants choosing to be involved in research may not be entirely representative for the group as a whole. The study is vulnerable to information bias, as the results are based on self-report measures and interviews.

Abstract
BACKGROUND The effects of Anabolic Androgenic Steroids (AAS) are largely illustrated through Androgen Receptor induced gene transcription, yet RNA-Seq has yet to be conducted on human whole blood and skeletal muscle. Investigating the transcriptional signature of AAS in blood may aid AAS detection and in muscle further understanding of AAS induced hypertrophy. METHODS Males aged 20-42 were recruited and sampled once: sedentary controls (C), resistance trained lifters (RT) and resistance trained current AAS users (RT-AS) who ceased exposure ≤ 2 or ≥ 10 weeks prior to sampling. RT-AS were sampled twice as Returning Participants (RP) if AAS usage ceased for ≥ 18 weeks. RNA was extracted from whole blood and trapezius muscle samples. RNA libraries were sequenced twice, for validation purposes, on the DNBSEQ-G400RS with either standard or CoolMPS PE100 reagents following MGI protocols. Genes were considered differentially expressed with FDR < 0.05 and a 1.2- fold change. RESULTS Cross-comparison of both standard reagent whole blood (N = 55: C = 7, RT = 20, RT-AS ≤ 2 = 14, RT-AS ≥ 10 = 10, RP = 4; N = 46: C = 6, RT = 17, RT-AS ≤ 2 = 12, RT-AS ≥ 10 = 8, RP = 3) sequencing datasets, showed that no genes or gene sets/pathways were differentially expressed between time points for RP or between group comparisons of RT-AS ≤ 2 vs. C, RT, or RT-AS ≥ 10. Cross-comparison of both muscle (N = 51, C = 5, RT = 17, RT-AS ≤ 2 = 15, RT-AS ≥ 10 = 11, RP = 3) sequencing (one standard & one CoolMPS reagent) datasets, showed one gene, CHRDL1, which has atrophying potential, was upregulated in RP visit two. In both muscle sequencing datasets, nine differentially expressed genes, overlapped with RT-AS ≤ 2 vs. RT and RT-AS ≤ 2 vs. C, but were not differentially expressed with RT vs. C, possibly suggesting they are from acute doping alone. No genes seemed to be differentially expressed in muscle after the long-term cessation of AAS, whereas a previous study found long term proteomic changes. CONCLUSION A whole blood transcriptional signature of AAS doping was not identified. However, RNA-Seq of muscle has identified numerous differentially expressed genes with known impacts on hypertrophic processes that may further our understanding on AAS induced hypertrophy. Differences in training regimens in participant groupings may have influenced results. Future studies should focus on longitudinal sampling pre, during and post-AAS exposure to better control for confounding variables.

Abstract
This study examined the relationship between intimate partner violence (IPV) and use of anabolic-androgenic steroids (AAS), in a relationship context, among men who have sex with men (MSM). The sample was collected online via Prolific.co and consisted of 491 MSM. Data were analyzed using structural equation modeling. While accounting for the influence of factors known to be linked to IPV (adverse childhood experiences and alcohol use), the use of AAS in a relationship context was uniquely linked to greater perpetration of IPV. AAS use was not uniquely linked to IPV victimization. Findings from this study contribute to literature on IPV among MSM by including a group-specific risk factor (AAS use) in modeling risk for IPV. Limitations, implications, and future directions for research are discussed.

Abstract
BACKGROUND Recreational use of anabolic-androgenic steroids (AAS) is a public health concern world-wide associated with a range of physical and psychological side effects. Still, people who use AAS tend to be reluctant to seek treatment. This study aims to explore use characteristics, treatment-seeking behaviour, side effects and associated health concerns among men with AAS use. METHODS The study includes cross-sectional self-report data from 90 men with a current or previous use of AAS exceeding 12 months, where 41 (45.6%) had sought treatment at least once during their lifetime, and 49 (54.4%) had not. Health service engagement was examined with descriptive statistics on reasons for contacting health services, transparency about AAS use, satisfaction with health services and reasons for not seeking treatment. Furthermore, experienced side effects and health concerns were compared between the treatment seeking and the non-treatment seeking group, using two-sample t-tests and Chi2 or Fisher exact tests for numerical and categorical variables, respectively. RESULTS All 90 AAS-using men reported side effects from AAS use. Treatment seekers were significantly younger, experienced more side effects including gynecomastia, excessive sweating, fatigue, depression and anxiety, and expressed more concern for testosterone deficiency. Preventive health check-up was the most common reason for seeking treatment (n = 22, 53.7%), and 38 men (93%) were transparent about AAS use during consultations with health professionals. The main reported reasons for not seeking healthcare services were that the experienced side effects were not considered to be of treatment demanding nature (n = 39, 79.6%) and the belief that healthcare providers had scarce knowledge about AAS use and its health impacts (n = 12, 24.5%). CONCLUSIONS Reluctance to seek treatment among people who use AAS, despite having associated side effects and health concerns, may contribute to continued health risks. It is important to fill the knowledge gap on how to reach and treat this new patient group, and policy makers and treatment providers need to be educated on how to meet their treatment needs.

Abstract
The history of the development of the cell transformation assays (CTAs) is described, providing an overview of in vitro cell transformation from its origin to the new transcriptomic-based CTAs. Application of this knowledge is utilized to address how the different types of CTAs, variously addressing initiation and promotion, can be included on a mechanistic basis within the integrated approach to testing and assessment (IATA) for non-genotoxic carcinogens. Building upon assay assessments targeting the key events in the IATA, we identify how the different CTA models can appropriately fit, following preceding steps in the IATA. The preceding steps are the prescreening transcriptomic approaches, and assessment within the earlier key events of inflammation, immune disruption, mitotic signaling and cell injury. The CTA models address the later key events of (sustained) proliferation and change in morphology leading to tumor formation. The complementary key biomarkers with respect to the precursor key events and respective CTAs are mapped, providing a structured mechanistic approach to represent the complexity of the (non-genotoxic) carcinogenesis process, and specifically their capacity to identify non-genotoxic carcinogenic chemicals in a human relevant IATA.

Adenosine receptors participate in anabolic-androgenic steroid-induced changes on risk assessment/anxiety-like behaviors in male and female rats. Physiol Behav 2023; 261:114071. [PMID: 36584765 DOI: 10.1016/j.physbeh.2022.114071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 12/24/2022] [Accepted: 12/26/2022] [Indexed: 12/29/2022]
Abstract
Anabolic-androgenic steroids (AAS) and caffeine can induce several behavioral alterations in humans and rodents. Administration of nandrolone decanoate is known to affect defensive responses to aversive stimuli, generally decreasing inhibitory control and increasing aggressivity but whether caffeine intake influences behavioral changes induced by AAS is unknown. The present study aimed to investigate behavioral effects of caffeine (a non-selective antagonist of adenosine receptors) alone or combined with nandrolone decanoate (one of the most commonly AAS abused) in female and male Lister Hooded rats. Our results indicated that chronic administration of nandrolone decanoate (10 mg/kg, i.m., once a week for 8 weeks) decreased risk assessment/anxiety-like behaviors (in the elevated plus maze test), regardless of sex. These effects were prevented by combined caffeine intake (0.1 g/L, p.o., ad libitum). Overall, the present study heralds a key role for caffeine intake in the modulation of nandrolone decanoate-induced behavioral changes in rats, suggesting adenosine receptors as candidate targets to manage impact of AAS on brain function and behavior.

Abstract
1. Testosterone has an anabolic effect on skeletal muscle. The testes produce most of the testosterone in vivo, while the adrenal glands contribute smaller amounts. When testis testosterone is deficient the adrenal gland increases steroid hormone synthesis, which is referred to as compensatory testicular adaptation (CTA).2. To reveal the effects of testis testosterone deficiency on adrenal steroid hormones synthesis and skeletal muscle development, gene expression related to adrenal steroid hormones synthesis and skeletal muscle development were determined by RNA-seq.3. The results showed that castrating male ducks had significant effects on their body weight but no significant impact on cross-sectional area (CSA) or density of pectoral muscle fibres. In skeletal muscle protein metabolism, expression levels of the catabolic gene atrogin1/MAFbx and the anabolic gene eEF2 were significantly higher, with concomitant increases after castration. The adrenal glands' alteration of the steroid hormone 11β-hydroxylase (CYP11B1) was significantly lower following castration.4. Expression pattern analysis showed that the adrenal glands' glucocorticoid receptor (NR3C1/GR) had a potential regulatory relationship with the skeletal muscle-related genes (Pax7, mTOR, FBXO32, FOXO3, and FOXO4).5. The data showed that castration affected muscle protein metabolism, adrenal steroid and testosterone synthesis. In addition, it was speculated that, after castration, steroid hormones produced by the adrenal gland could have a compensatory effect, which might mediate the changes in skeletal muscle protein metabolism and development.

Abstract
INTRODUCTION Anabolic-androgenic steroids (AASs) are a complex cluster of synthetic derivatives of testosterone. AAS abuse is considered a major public health issue since it has increased among young/adolescent males. The use of steroids has a prevalence rate of 14% in young athletes and 30-75% in professional athletes or bodybuilders. AASs simulate the testosterone mechanism, binding the intracellular androgen receptor, and dysregulating the normal hypothalamic-pituitary-gonadal axis in the same way as exogenous testosterone. Abuse can produce several side effects on organs, such as the genital system. The physio-pathological mechanisms that cause AAS abuse-related, genital system disorders in humans are still not completely known. EVIDENCE ACQUISITION This study focuses on the effect of AASs on the male reproductive organs in humans and animals. EVIDENCE SYNTHESIS A systematic review was performed using SCOPUS, PubMed, Google Scholar, and Web of Sciences database up to 31 December 2021 using the keywords: "anabolic-androgenic steroids," "erectile dysfunction," "spermatogenesis" and "infertility;" (anabolic agents) "erectile dysfunction," "spermatogenesis" and "infertility." The review of the literature identified 66 articles published until 2021. Sixty-two articles were included. The use of AASs induces testicular atrophy and azoospermia known as "anabolic steroid-induced hypogonadism." Anabolic steroid induced infertility is characterized by oligo or azoospermia and abnormalities in sperm motility and morphology. Although sperm quality recovers in most cases within 4 months of stopping anabolic steroid abuse, the negative consequences on spermatogenesis can take up to 3 years to disappear. Human studies reported a positive correlation between AAS abuse in athletes and an increase in morphologically abnormal spermatozoa. Animal studies showed the destruction of Leydig cells and testicular atrophy in animals treated with cycles of AASs. CONCLUSIONS The present review of the literature highlights how little is known about the action of AASs on the male genital system. However, although their use is prohibited in many countries, the black market for these substances is still very frequent. The scientific landscape still has a lot to invest in the research of AAS on the male genital system to make young people even more aware of the negative aspects of these substances, contributing to the reduction of these products in an inappropriate way.

Abstract
Anabolic-androgenic steroids (AAS) are a class of hormones that are widely abused for their muscle-building and strength-increasing properties in high, nontherapeutic, dosages. This review provides an up-to-date and comprehensive overview on how these hormones work and what side effects they might elicit. We discuss how AAS are absorbed into the circulation after intramuscular injection or oral ingestion and how they are subsequently transported to the tissues, where they will move into the extravascular compartment and diffuse into their target cells. Inside these cells, AAS can biotransform into different metabolites or bind to their cognate receptor: the androgen receptor. AAS and their metabolites can cause side effects such as acne vulgaris, hypertension, hepatotoxicity, dyslipidemia, testosterone deficiency, erectile dysfunction, gynecomastia, and cardiomyopathy. Where applicable, we mention treatment options and self-medication practices of AAS users to counteract these side effects. Clinicians may use this review as a guide for understanding how AAS use can impact health and to assist in patient education and, in some cases, the management of side effects.

Abstract
In December 2019, the World Health Organization was informed of an outbreak of pneumonia of unknown etiology in Wuhan, Hubei Province, China. On January 7, 2020, a new type of coronavirus was isolated, with the WHO later officially calling it “COVID-19” and the International Committee on Taxonomy of Viruses naming the virus “SARS-CoV-2”. On January 30, 2020, the WHO declared the severe acute respiratory syndrome coronavirus 2 outbreak a public health emergency of international concern, making it an unprecedented global public health challenge. From a scientific and literary reference, it was established that the main drugs in the therapy with Covid-19 are Dexamethasone and Levofluoxetine. For this reason, we pay attention to the analysis of these two medicinal products. In the literature, we did not find an analysis of a combination of Dexamethasone and Levofloxacin. Development and validation of a highperformance liquid chromatographic analytical procedure for simultaneously determining Dexamethasone and Levofloxacin in a synthetic mixture is described in this paper. The separation was made with a LiChrosorb RP 18 (250 × 4.6 mm) column, at 25 °C temperature,with isocratic mode andmobile phase,containingt acetonitrile and woter (70-30v/v). Eluent was monitored at 254 nm and the flow rate was 1.0 ml/min. Dexamethasone and Levofluoxetine were effectively separated with retention time (tr) of 4.69 min and 14.51 min,respectively,with in the selected chromatographic conditions.The method was validated for analytical parameters: specificity, linearity, precision, accuracy,andlimits of detection and quantitation. The calibration curves were linear inthe concentration range of 12.5 to 100.0 μg/ml for Dexamethasone and Levofloxacin, and the regression coefficientswere more than 0.999. For Dexamethasone and Levofloxacin the recovery was 100.01% and 100.04%, respectively. This analytical procedure is applicable for the quality control of drug formulations.

Abstract
The use of anabolic steroids affects not only professional athletes but also the general population (bodybuilders, gym clients, and adolescents). In the first case, its use is prohibited and sanctioned by the World Anti-Doping Agency and Olympic committees. For the other users, it is difficult to establish its prevalence since many obtain the products via the internet. The reasons for its use are varied and different forms of use and other types of users have been described. Among the side effects of steroid use, hypogonadism is the most frequent cause for endocrinological consultation. After a general introduction to doping, this review describes the historical background of anabolic-androgenic steroids, their classification, forms of use, physiological effects, adverse effects on different organs and systems, treatment of hypogonadism, as well as detection methods.

Abstract
Aging is associated with a progressive decrease in skeletal muscle mass, strength and power and impairment of physical function. Serum testosterone concentrations in men decrease with advancing age due to defects at all levels of the hypothalamic-pituitary-testicular axis. Testosterone administration increases skeletal muscle mass, strength and power in older men with low or low normal testosterone levels, but the effects on performance-based measures of physical function have been inconsistent. Adequately powered randomized trials are needed to determine the long-term safety and efficacy of testosterone in improving physical function and quality of life in older adults with functional limitations.

Abstract
Anabolic-androgenic steroids (AAS) are primarily used to improve physical appearance and increase lean muscle mass. Due to their masculinizing properties, the majority of people using AAS are men; however, AAS use among females may increase with changing body ideals trending towards a more muscular appearance. AAS use among males have been associated with risk-taking behavior, and increased prevalence of personality disorders and psychopathology. As a result of low perceived prevalence and stigma among females who use AAS, the relationship between AAS use and psychopathology in this population is not well-known. AAS using women (n = 16) and weight-lifting controls (WLC) (n = 16) completed questionnaires regarding AAS use, health and training information. Psychopathology was evaluated using the Millon Clinical Multiaxial Inventory-III (MCMI-III). Group differences on demographic variables and scores on MCMI-III scales were evaluated with Mann-Whitney U tests. The clinical cut-off was then applied to all MCMI-III scales and groups were compared using Fisher's exact test. AAS consumers demonstrated significantly greater psychopathology than WLC on several scales. Externalizing personality disorder scales were elevated among those who use AAS relative to controls, such as borderline (p < 0.001), antisocial (p = 0.007) and sadistic (p = 0.002), and in addition depressive (p = 0.012), negativistic (p = 0.001) and masochistic (p = 0.029) personality disorders scales. Furthermore, all clinical syndromes were elevated among AAS consumers. AAS consumers thus demonstrated multi-pathology, and 56% (n = 9) of the group met the clinical criteria for six or more disorders. Females who use AAS experience in general increased levels of psychopathology compared to WLC. Clinicians should be aware of these traits and the challenges they present in providing care to this population.

Abstract
Arterial hypertension is a global public health concern. In the last few years, the interest in androgen deficiency has been growing, and the association between androgens and high blood pressure (BP) is still controversial. One purpose of this review was to summarize the available findings in order to clarify whether male sex steroid hormones have beneficial or harmful effect on BP. The second purpose was to enhance the recognition of the acute non-genomic sex-independent vasorelaxing effect of androgens. Remarkably, BP variation is expected to be a consequence of the androgen-induced vasorelaxation which reduces systemic BP; hence the in vivo vasodepressor, hypotensive, and antihypertensive responses of androgens were also analyzed. This article reviews the current understanding of the physiological regulation of vascular smooth muscle contractility by androgens. Additionally, it summarizes older and more recent data on androgens, and some of the possible underlying mechanisms of relaxation, structural-functional differences in the androgen molecules, and their designing ability to induce vasorelaxation. The clinical relevance of these findings in terms of designing future therapeutics mainly the 5-reduced metabolite of testosterone, 5β-dihydrotestosterone, is also highlighted. Literature collected through a PubMed database search, as well as our experimental work, was used for the present review.

Abstract
Background To explore the feasibility, safety, and potential benefits of administration of the anabolic steroid nandrolone to patients in the recovery phase from critical illness weakness. Methods In this phase II, double blind, randomized, controlled trial, adult critically ill patients admitted to one of two tertiary Intensive Care Units in Western Australia for longer than 7 days with significant weakness were enrolled. Patients received nandrolone (200 mg males, 100 mg females) intramuscularly or placebo weekly for up to 3 weeks in addition to standard care. The primary outcome measures were improvement in grip strength, Medical Research Council muscle strength sum score, and functional activity level (Chelsea critical care assessment tool [CPAx]). Results A total of 22 patients was enrolled between September 2017 and May 2019. No significant adverse events were detected. Median grip strength change was non-significantly greater in the nandrolone group (8.5 vs. 13.0, P=0.185), while hospital length of stay (36 vs. 26 days, P=0.023) and duration of mechanical ventilation (377 vs. 168, P=0.032) were lower. The discharge CPAx and intensive care unit mobility scores were higher in the nandrolone group, although there was no difference in the change in CPAx score (17.0 vs. 17.7, P=0.865). There were no changes in ultrasound-detected muscle thickness between the two groups. Conclusions In patients with prolonged critical illness, nandrolone appears to be safe. However, a larger study, potentially combined with resistance exercise, is needed to definitively address the potential benefits of nandrolone.

Abstract
(Background) The aim of our study was to evaluate the efficacy and safety of testosterone replacement therapy (TRT) in men with chronic kidney disease and hypogonadism on conservative and hemodialysis treatment. (Methods) The studied population consisted of 38 men on hemodialysis (HD), 46 men with CKD stages II-IV (predialysis group, PreD) and 35 men without kidney disease who were similar in age to others (control group). Serum total testosterone level (TT) was measured, and free testosterone level (fT) was calculated. Hypogonadism criteria according to the EAU definition were fulfilled by 26 men on HD (68.4%) and by 24 men from the PreD group (52%). Testosterone replacement therapy (TRT) with testosterone enanthate in intramuscular injections every 3 weeks was applied in 15 men from HD and in 14 men from PreD. The safety of TRT was monitored by measuring PSA and overhydration. (Results) A significant rise of TT and fT was observed after 3 months of TRT, but no significant changes were observed after 6 and 12 months in the HD and PreD group. An intensity of clinical symptoms of hypogonadism measured by ADAM (androgen deficiency in the ageing male) questionnaire gradually decreased, and the intensity of erectile dysfunction measured by the IIEF-5 (international index of erectile functioning) questionnaire also decreased after 3, 6 and 12 months of TRT in the HD and PreD group. (Conclusions) The applied model of TRT is effective in the correction of clinical signs of hypogonadism without a significant risk of overhydration or PSA changes.

Abstract
This experiment was established to evaluate the influence of synthetic steroid hormone and aromatase inhibitor on performance, carcass characteristics, hormonal profile and gonadal structure of broiler chickens slaughtered at two different ages. A total of 360 Cobb Avian48 chicks were sexed and distributed randomly into three groups: Tam10 group; birds received Tamoxifen10mg (Tamfen 10 mg@ ) orally at a level of 10 mg/kg body weight daily from the 3rd till the 9th day of age; BOL group: birds injected intramuscularly with Boldenone undecylenate (BOLD-GAN@ 0.1 mg/kg) at the 5th and the 9th day of age; and Control group. BOL injection or Tam supplementation improved performance traits compared with the control group. Although Tam positive effect appeared early before the 5th week of age, the BOL effect was delayed to the 6th week. BOL injection improved carcass characteristics of both sexes at both 5 and 6 weeks slaughtering ages. Regardless of treatment effect, the mortality% was higher in the late weeks of age than in the early weeks. Moreover, BOL treatment increased comb% compared with control and Tam treatments. Generally, males had significantly higher testosterone levels and lower oestrogen levels than females. Males treated with Boldenone had the highest testosterone level, although testosterone levels did not differ considerably among females of the various groups. BOL treatment females had the lowest oestrogen level. Both Tam10 and Boldenone had adverse effects on testicular and ovarian histology, affecting the typical structures. Finally, we concluded that the anabolic effect of Tam10 may be achieved in griller broilers production without changing the sex hormones assay. Although Boldenone achieved an anabolic effect without changing blood sex hormone levels, this effect is induced early with females and delayed with males, which prolongs the marketing period. The goal is to shorten this period. Therefore, this material can only be used with the possibility of separating females from males to be used with females only.

Abstract
The androgen receptor (AR) plays a key role in the maintenance of muscle and bone and the support of male sexual-related functions, as well as in the progression of prostate cancer. Accordingly, AR-targeted therapies have been developed for the treatment of related human diseases and conditions. AR agonists are an important class of drugs in the treatment of bone loss and muscle atrophy. AR antagonists have also been developed for the treatment of prostate cancer, including metastatic castration-resistant prostate cancer (mCRPC). Additionally, selective AR degraders (SARDs) have been reported. More recently, heterobifunctional degrader molecules of AR have been developed, and four such compounds are now in clinical development for the treatment of human prostate cancer. This review attempts to summarize the different types of compounds designed to target AR and the current frontiers of research on this important therapeutic target.

Abstract
For decades, anabolic androgenic agents have represented the substance class most frequently observed in doping control samples. They comprise synthetic and pseudoendogenous anabolic androgenic steroids and other, mostly non-steroidal compounds with (presumed) positive effects on muscle mass and function. While exogenous substances can easily be detected by gas/liquid chromatography and mass spectrometry, significantly more complex methodologies including the longitudinal monitoring of individual urinary steroid concentrations/ratios and isotope ratio mass spectrometry are required to provide evidence for the exogenous administration of endogenous compounds. This narrative review summarizes the efforts made within the last 5 years to further improve the detection of anabolic agents in doping control samples. Different approaches such as the identification of novel metabolites and biomarkers, the acquisition of complementary mass spectrometric data, and the development of new analytical strategies were employed to increase method sensitivity and retrospectivity while simultaneously reducing method complexity to facilitate a higher and faster sample throughput.

Abstract
Inhibiting the androgen receptor (AR), a ligand-activated transcription factor, with androgen deprivation therapy is a standard-of-care treatment for metastatic prostate cancer. Paradoxically, activation of AR can also inhibit the growth of prostate cancer in some patients and experimental systems, but the mechanisms underlying this phenomenon are poorly understood. This study exploited a potent synthetic androgen, methyltestosterone (MeT), to investigate AR agonist-induced growth inhibition. MeT strongly inhibited growth of prostate cancer cells expressing AR, but not AR-negative models. Genes and pathways regulated by MeT were highly analogous to those regulated by DHT, although MeT induced a quantitatively greater androgenic response in prostate cancer cells. MeT potently downregulated DNA methyltransferases, leading to global DNA hypomethylation. These epigenomic changes were associated with dysregulation of transposable element expression, including upregulation of endogenous retrovirus (ERV) transcripts after sustained MeT treatment. Increased ERV expression led to accumulation of double-stranded RNA and a "viral mimicry" response characterized by activation of IFN signaling, upregulation of MHC class I molecules, and enhanced recognition of murine prostate cancer cells by CD8+ T cells. Positive associations between AR activity and ERVs/antiviral pathways were evident in patient transcriptomic data, supporting the clinical relevance of our findings. Collectively, our study reveals that the potent androgen MeT can increase the immunogenicity of prostate cancer cells via a viral mimicry response, a finding that has potential implications for the development of strategies to sensitize this cancer type to immunotherapies. Significance Our study demonstrates that potent androgen stimulation of prostate cancer cells can elicit a viral mimicry response, resulting in enhanced IFN signaling. This finding may have implications for the development of strategies to sensitize prostate cancer to immunotherapies.

Understanding and managing the suppression of spermatogenesis caused by testosterone replacement therapy (TRT) and anabolic–androgenic steroids (AAS). Ther Adv Urol 2022; 14:17562872221105017. [PMID: 35783920 PMCID: PMC9243576 DOI: 10.1177/17562872221105017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 05/17/2022] [Indexed: 11/16/2022] Open
Abstract
Use of testosterone replacement therapy (TRT) and anabolic–androgenic steroids
(AAS) has increased over the last 20 years, coinciding with an increase in men
presenting with infertility and hypogonadism. Both agents have a detrimental
effect on spermatogenesis and pose a clinical challenge in the setting of
hypogonadism and infertility. Adding to this challenge is the paucity of data
describing recovery of spermatogenesis on stopping such agents. The unwanted
systemic side effects of these agents have driven the development of novel
agents such as selective androgen receptor modulators (SARMs). Data showing
natural recovery of spermatogenesis following cessation of TRT are limited to
observational studies. Largely, these have shown spontaneous recovery of
spermatogenesis after cessation. Contemporary literature suggests the time frame
for this recovery is highly variable and dependent on several factors including
baseline testicular function, duration of drug use and age at cessation. In some
men, drug cessation alone may not achieve spontaneous recovery, necessitating
hormonal stimulation with selective oestrogen receptor modulators
(SERMs)/gonadotropin therapy or even the need for assisted reproductive
techniques. However, there are limited prospective randomized data on the role
of hormonal stimulation in this clinical setting. The use of hormonal
stimulation with agents such as gonadotropins, SERMs, aromatase inhibitors and
assisted reproductive techniques should form part of the counselling process in
this cohort of hypogonadal infertile men. Moreover, counselling men regarding
the detrimental effects of TRT/AAS on fertility is very important, as is the
need for robust randomized studies assessing the long-term effects of novel
agents such as SARMs and the true efficacy of gonadotropins in promoting
recovery of spermatogenesis.
