Extensive androgen exposure and meningioma risk - A matched cohort study.

INTRODUCTION: Meningiomas frequently occur within the field of neuro-oncology, but it is unclear whether exogenous or imbalanced endogenous hormones are involved in the pathophysiology. A previous case-control study found an almost 20-fold increase in the risk of developing meningioma among users of androgenic anabolic steroids. We, therefore, investigated this hypothesis. METHODS: We compared the incidence rate of meningioma in a cohort of males sanctioned for the use of androgenic anabolic steroids with age- and sex-matched controls with an identical enrollment date. RESULTS: We followed 1189 males sanctioned for using androgenic anabolic steroids for a total of 13,305 person-years and found 0 cases of meningioma. The control cohort of 59,450 males was followed for a total of 654,938 person-years, and 16 were diagnosed with meningioma. Thus, the incidence rate ratio was 0 (95% CI: 0-12.8). CONCLUSION: We did not find any evidence supporting the hypothesis of an increased risk of meningioma development with the use of androgenic anabolic steroids. Due to the limited sample size, we cannot exclude androgenic anabolic steroids as a potential risk factor for meningioma development, despite the lack of apparent evidence in this study.

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.

Appearance and performance factors associated with muscle building supplement use and favourable attitudes towards anabolic steroids in adolescent boys.

Introduction: The demand for appearance and performance enhancing substances, including muscle building supplements and anabolic androgenic steroids, is increasing in Australia. However, little is known about the associations between appearance and performance-based factors and appearance and performance enhancing substances (APES), particularly among adolescent boys. This study sought to examine (a) the prevalence of muscle building supplement use in a sample of adolescent boys and (b) how both performance and appearance factors relate to muscle building supplement use and favourable attitudes towards anabolic androgenic steroids in this sample. Method: N = 488 adolescent boys aged 13-16 (Mage = 14.59) from nine Australian schools completed measures of supplement use, favourable attitudes towards using steroids, muscle dissatisfaction, body fat dissatisfaction, mesomorphic ideal internalisation, weight training, and sports participation. Hierarchical logistic regressions were used to examine cross-sectional correlates of muscle building supplement use and favourable attitudes towards using anabolic androgenic steroids. Results: In the past three months, 12.7% of the sample had used muscle building supplements. Both appearance and performance-related factors - mesomorphic ideal internalisation and weight training - were related to muscle building supplement use. Only one appearance-related factor - body dissatisfaction - was related to favourable attitudes towards anabolic androgenic steroids. Discussion: The findings from this study are important as they may help to guide intervention strategies regarding appearance and performance enhancing substance use by Australian adolescent boys, with the ultimate goal of ensuring this population's safety.

Anabolic-androgenic anabolic steroids as a probable risk factor for hepatoblastoma in infants.

Key Clinical Message: The etiology of hepatoblastoma (HB) is still unknown; several risk factors have been identified. The only risk factor for the development of HB in presented case was the child's father using anabolic androgenic steroids. It may be a risk factor for developing HB in their children. Abstract: HB is the most common primary liver cancer in children. Its etiology is still unclear. The patient's father's use of androgenic anabolic steroids could be a risk factor for developing HB in his child. A 14-month-old girl was hospitalized with intermittent fever, severe abdominal distention, and anorexia. On initial examination, she was cachectic and pale. There were two hemangioma-like skin lesions in the back. Huge hepatomegaly was found and the ultrasound showed a hepatic hemangioma. The possibility of malignancy was considered due to the severe enlargement of the liver and the increased levels of the alpha-fetoprotein. An abdominopelvic CT scan was performed and finally, the diagnosis of HB was confirmed by pathology. There was no history of congenital anomalies or risk factors for HB.Also we did not find any risk factors in the mother's history either. The only positive finding in the father's history was the use of anabolic steroids for bodybuilding. Anabolic-androgenic anabolic steroids may be one of the possible causes of HB in children.

Higher Myonuclei Density in Muscle Fibers Persists Among Former Users of Anabolic Androgenic Steroids.

CONTEXT: No information exists on the long-lasting effects of supraphysiological anabolic androgenic steroids (AASs) usage on the myocellular properties of human skeletal muscle in previous AAS users. OBJECTIVE: We hypothesized that former AAS users would demonstrate smaller myonuclei domains (ie, higher myonuclei density) than matched controls. METHODS: A community-based cross-sectional study in men aged 18-50 years engaged in recreational strength training. Muscle biopsies were obtained from the m. vastus lateralis. Immunofluorescence analyses were performed to quantify myonuclei density and myofiber size. RESULTS: Twenty-five males were included: 8 current and 7 previous AAS users and 10 controls. Median (25th-75th percentiles) accumulated duration of AAS use was 174 (101-206) and 140 (24-260) weeks in current and former AAS users, respectively (P = .482). Geometric mean (95% CI) elapsed duration since AAS cessation was 4.0 (1.2; 12.7) years among former AAS users. Type II muscle fibers in former AAS users displayed higher myonuclei density and DNA to cytoplasm ratio than controls, corresponding to smaller myonuclei domains (P = .013). Longer accumulated AAS use (weeks, log2) was associated with smaller myonuclei domains in previous AAS users: beta-coefficient (95% CI) -94 (-169; -18), P = .024. Type I fibers in current AAS users exhibited a higher amount of satellite cells per myofiber (P = .031) than controls. CONCLUSION: Muscle fibers in former AAS users demonstrated persistently higher myonuclei density and DNA to cytoplasm ratio 4 years after AAS cessation suggestive of enhanced retraining capacity.

Do you get what you see? The illicit doping market in Denmark-An analysis of performance and image enhancing drugs seized by the police over a 1-year period.

This study examines doping products seized by the police in three regional police districts in Denmark from December 2019 to December 2020. The products, often referred to as performance and image-enhancing drugs (PIEDs), are described in relation to the country of origin, manufacturing company, and the active pharmaceutical ingredient (API) stated on the packaging versus the one identified by subsequent chemical analysis. The study also includes a description of the degree of professionalism by which the products appear according to EU requirements. A total of 764 products were seized during the study period. The products originate from 37 countries, mainly located in Asia (37%), Europe (23%), and North America (13%). One hundred ninety-three different manufacturing companies could be identified from the product packaging. The most frequent compound class was the androgenic anabolic steroids, found in 60% of the products. In 25%-34% of the products, either no or an incorrect API relative to the one stated on the product was found. However, only 7%-10% contain either no API or a compound from a different compound class than the one stated. Most products had a professional appearance fulfilling most EU requirements for packaging information. The study shows that many different companies supply PIEDs to the Danish market and that counterfeit and substandard products are widespread. Many products do, however, appear professional to the user giving an impression of a high-quality product. Although many products are substandard, they most often contain an API from the same compound class as the one labeled.

Use of Anabolic-Androgenic Steroids and Male Fertility: A Systematic Review and Meta-analysis.

Background: Anabolic-androgenic steroids (AASs) are often used by men for bodybuilding and to improve sports performance. The use is not limited to professional competitive athletes, but many amateur men. Objective: The objective of this study was to assess and systematically review the effects of AAS on male fertility parameters, spermiogram, testosterone, follicle-stimulating hormone (FSH) and luteinising hormone (LH) and to review reversibility and other morbidity impacting fertility. Methods: Eligibility criteria - We included studies mentioning data about adult males using supraphysiologic doses of AAS for sports performance or appearance enhancement, with comparison data from general population or matched controls if available reporting fertility parameters and sexual performance. Information sources - A systematic literature search was performed using PubMed, MEDLINE, EMBASE, Google Scholar and World of Science. Controlled clinical trials randomised or nonrandomised (if available), case series with or without matched controls, case reports, cross-sectional surveys, reports on follow-up of subjects caught in doping test and their fertility parameters when reported. Risk of bias/quality assessment - The quality assessment of the included studies was performed using the Newcastle-Ottawa Scale. Results: Included studies - Thirty-two studies were included. There were 12 cohort studies, 5 case-control studies, 9 cross-sectional surveys and 6 case reports. The study population comprised 9371 individuals, of which 2671 were AAS users. Synthesis of results - AAS users had reduced levels of FSH and LH than the naïve population. These levels remained low for 3-6 months after stopping AAS. One year after stopping AAS, the users and naïve population had insignificant differences in FSH and LH values. The total testosterone (TT) levels were comparable in users and naïve populations at baseline, 3 months and 6 months after stopping, but at 1 year, TT values were lower in AAS users. Sperm concentration in AAS users and naïve population was similar, but sperm motility was lower in AAS users. The testicular size was lower in AAS users. The erectile function improved with AAS use, but on withdrawal, there was decreased libido and erectile dysfunction. Most AAS users need additional medications to mitigate detrimental effects on fertility. Description of the effect - AAS use negatively impacted the gonadotrophin levels and had lower sperm motility and testicular size. Strength - Comprehensive review of 32 publications, study population of 9371 individuals, of which 2671 were AAS users, meta-analysis of reproductive hormones, semen parameters and testis size. Limitations: The limitations are small sample size of most of the studies, polypharmacy, lack of information on dosing and high heterogeneity. Interpretation: AAS use is detrimental for sperm motility and has a partially reversible negative impact on male fertility. Users must be cautioned about its negative impact on libido and erectile function.Registration: PROSPERO Registration No. CRD42023411294.

Psychiatric morbidity among men using anabolic steroids.

OBJECTIVE: The purpose of this study was to investigate the psychiatric morbidity among men with abuse of anabolic steroids. METHODS: The design is a retrospectively matched cohort study. Five hundred and fourty-five males, who tested positive for anabolic steroids in Danish fitness centers during the period January 3, 2006 to March 1, 2018, were matched with 5450 randomly chosen male controls. Data was cross-referenced with seven national registers pertaining to information about education, employment status, and psychiatric comorbidity. Main outcomes and measures were prescription of psychopharmacological treatment. RESULTS: The incidence of treatment with anxiolytics (HR: 2.34, 95% CI: 1.62-3.38) and antipsychotics (HR: 2.69, 95% CI: 1.99-3.63) displayed a remarkable increase in the years following doping sanction, compared to the control group. The prevalence of antidepressant use was already markedly elevated several years before doping sanction, but also displayed a higher incidence in the years following sanction (HR: 1.65, 95% CI: 1.28-2.13). The associations remained highly significant after controlling for socioeconomic factors. CONCLUSION: Anabolic steroids use is strongly associated with psychiatric morbidity.

Androgenic-Anabolic Steroids: From the Gym to Drug-Induced Liver Injury.

Drug-induced liver injury (DILI) is a frequent cause of liver toxicity. We describe the case of a 32-year-old male patient without any relevant past medical history or medication use. In the past two months, he was engaged in weightlifting exercises and consumed androgenic-anabolic steroids to enhance his exercise routine. The patient initially experienced choluria and acholia for two weeks, followed by itching for two days, which led him to present to the emergency room. His laboratory results revealed cytocholestasis. He was admitted for investigations and after excluding other causes of liver injury, the diagnosis of DILI related to the consumption of androgenic-anabolic steroids was made. This case report highlights the perils of using performance-enhancing substances such as androgenic-anabolic steroids, which may lead to severe side effects like DILI.

The deleterious effects of anabolic androgenic steroid abuse on sexual and reproductive health and comparison of recovery between treated and untreated patients: Single-center prospective randomized study.

Anabolic androgenic steroids (AAS) abuse is a global health-related concern, as most of the related studies showed increasing trends and deleterious effects, mostly on sexual and fertility health. Unfortunately, there are no consensuses about the management pathways due to the lack of specific guidelines. We aimed to confirm the deleterious effects of AAS abuse, monitor the spontaneous recovery, and demonstrate the effects of treatment regimens on recovery. We enrolled 520 patients with a confirmed history of AAS intake within 1 year of presentation and evaluated their symptoms, hormones levels, and semen every 3 months until 12 months. All patients were monitored for spontaneous recovery in the first 3 months; if they showed no recovery, they were randomized to undergo either continued observation or commence medications. The most common presentation (84%) was a combination of sexual symptoms while some patients (18%) were infertile. Most patients (90%) reported low levels of luteinizing hormone, follicle-stimulating hormone, and total testosterone. After the 3-month observation, most patients (89%) started treatment, but some (11%) continued observation only. Treated patients showed faster improvement regarding the International Index of Erectile Function (IIEF) values, hormone levels, testicular size and semen parameters compared to non-treated patients (p < 0.005). Among the 94 patients who presented with infertility (18%), 61 had oligospermia and 33 had azoospermia. All received treatment, but only 14 (15%) achieved successful pregnancy at 12 months while all azoospermic's patients continued to have infertility at the end of the follow-up period. These findings demonstrated the significant negative impact of AAS abuse on sexual health and fertility, and the need for medical treatment to have faster recovery from their adverse effect.

Common symptoms associated with usage and cessation of anabolic androgenic steroids in men.

Anabolic-androgenic steroid (AAS) have widespread and growing illicit use as image and performance enhancing drugs (IPED), predominantly in young men. Users trying to stop AAS are prone to distressing withdrawal symptoms which may trigger relapse in use. It is important to develop therapies to support AAS withdrawal. The illicit nature of AAS use has impeded the robust characterisation of its clinical withdrawal syndrome within any single study. Therefore, we conducted a systematic review summarising the available clinical studies describing symptoms associated with non-medically indicated AAS use, and AAS withdrawal. Reported clinical features of AAS withdrawal include headache, fatigue, myalgia, restlessness, insomnia, low mood and libido, anorexia, suicidal ideation, body image dissatisfaction, and steroid cravings; novel therapies for AAS withdrawal would need evaluation against these symptoms.

Social Media, Body Image and Resistance Training: Creating the Perfect 'Me' with Dietary Supplements, Anabolic Steroids and SARM's.

BACKGROUND: Few studies have assessed the use of dietary supplements, anabolic androgenic steroids (AAS) and selective androgen receptor modulators (SARM) in male gym users. The comparison of physical appearance with others on social media and the exposure to fitness-related content on social media (i.e., image-centric social media use) may have a profound role in using these compounds due to its role in creating negative body images in male gym users. OBJECTIVE: Provide contemporary data on the use of dietary supplements, AAS and SARM among young male gym users, and test the hypothesis that social media is associated with the use of dietary supplements, AAS and SARM, as a result of a negative body image. METHODS: In this cross-sectional study, conducted in the Netherlands, male gym users (N = 2269; 24 ± 6 years) completed an online questionnaire including self-reported measures regarding resistance training participation, image-centric social media use, dietary supplement intake, and body image. The prevalence of AAS and SARM use was assessed with randomized response, a technique to ask sensitive questions indirectly. RESULTS: Of all participants, 83% used ergogenic dietary supplements (mainly protein and creatine), and an estimated 9 versus 2.7% had ever used AAS versus SARM. Image-centric social media use was positively associated with the use of dietary supplements (r = .26; p < 0.01) and AAS (p < 0.05), but not SARM. Image-centric social media use was associated with a more dissatisfied body image (r = .34; p < 0.01). Body image did not mediate the relationship between image-centric social media use and the use of doping compounds. CONCLUSIONS: The use of dietary supplements in young male gym users is exorbitant, with the use of AAS and SARM being substantial. Image-centric social media use is positively associated with the use of dietary supplements and AAS.

Random forest model to identify factors associated with anabolic-androgenic steroid use.

BACKGROUND: One of the types of doping that is commonly used by bodybuilders, is androgenic-anabolic steroids (AAS). The use of AAS besides violating sporting ethics would have serious consequences on physical and mental health statuses. This study aimed to determine the most important factors of using AAS among bodybuilders by prototype willingness model (PWM). METHODS: In this analytical cross-sectional study, 280 male bodybuilders were selected from the bodybuilding clubs in Hamadan city using multistage sampling in 2016. A self-administered questionnaire consisting of demographic information and constructs of the PWM was then used to collect data and random forest model was also applied to analyze the collected data. RESULTS: Behavioral willingness, attitude, and previous AAS use were found as the most important factors in determining the behavioral intention. Moreover, subjective norms, attitude, BMI, and prototypes were the factors with the greatest effect on predicting behavioral willingness of AAS use. As well, behavioral intention was observed to be more important than behavioral willingness for predicting of AAS use. DISCUSSION: The obtained results show that the reasoned action path has a greater impact to predict AAS use among bodybuilders compared to social reaction path.

The Effects of Testosterone on the Brain of Transgender Men.

Transgender men (TM) experience an incongruence between the female sex assigned when they were born and their self-perceived male identity. Some TM seek for a gender affirming hormone treatment (GAHT) to induce a somatic transition from female to male through continuous administration of testosterone. GAHT seems to be relatively safe. However, testosterone produces structural changes in the brain as detected by quantitative magnetic resonance imaging. Mainly, it induces an increase in cortical volume and thickness and subcortical structural volume probably due to the anabolic effects. Animal models, specifically developed to test the anabolic hypothesis, suggest that testosterone and estradiol, its aromatized metabolite, participate in the control of astrocyte water trafficking, thereby controlling brain volume.

An overview on performance and image enhancing drugs (PIEDs) confiscated in Italy in the period 2017-2019.

CONTEXT: The illegal market of counterfeit and falsified medicines and supplements containing unlabeled pharmaceuticals is expanding worldwide. They are usually referred to by the term "performance and image enhancing drugs" (PIEDs) and are mainly steroids, stimulants, hormones, and drugs for erectile dysfunction. PIEDs are easily accessible through the online or black markets. We analyzed over 400 such medicines confiscated in Italy in the period 2017-2019, to determine their composition. METHODS: Confiscated products were analyzed by gas chromatography/mass spectrometry and liquid chromatography/high-resolution mass spectrometry, in order to ascertain their composition and to evaluate the correspondence between what was declared on the label and the actual content, or to identify unknown products. RESULTS: The most commonly found substance was anabolic steroids, found in 64% of products, with 11% containing hormone modulators, 6% stimulants, 6% sexual enhancers (mainly sildenafil) and other drugs, including thyroid hormones, melanin stimulators, and vitamins. These substances were often in mixtures. The products were often mislabeled, containing contaminants in addition to the drug declared, or consisted of a drug completely different from the one reported on the label. Fifteen percent of products had a qualitative composition completely different from that declared, while 10% of products showed cross-contamination with other drugs, mainly testosterone esters, probably due to the presence of residues of other drugs in the production line. In addition, 11% of products were not labeled, so their purported composition was unknown. DISCUSSION: PIEDs pose a threat to public health. The main risks are related to the intrinsic toxicity of the substances found, especially when taken without a therapeutic indication. Another issue is related to the mislabeling of the fake medicines, and the poor-quality standard of counterfeit product preparation, with additional risks of the presence of other toxic ingredients or microbial contamination. CONCLUSIONS: The use of counterfeit products is a public health concern, as it constitutes a high risk for consumer health. It is mainly caused by the uncontrolled use of steroids, stimulants, sexual enhancers, and other medicaments, without medical indication or supervision, with variable and unknown compositions and doses, as well as other contaminants as a result of the absence of good manufacturing practices.

Male Fertility Before and After Androgen Abuse.

PURPOSE: Previous research has found that male users of androgens are diagnosed approximately twice as often with infertility. We therefore set out to investigate the fertility in men using androgens. METHODS: The study included 545 males who tested positive for androgens in an anti-doping test program in Danish fitness centers during the period from January 3, 2006, to March 1, 2018. The confirmed androgen users were matched by birth year with 5450 male controls. We followed this cohort from 10 years prior to testing positive until the end of follow-up in May 2018. RESULTS: During the 10-year period prior to testing positive, the group of androgen users experienced a 26% lower fertility rate than the controls (rate ratio [RR] 0.74; 95% CI, 0.60-0.90; P = 0.0028). However, in the years following the doping sanction, they made a significant catch-up, and at completed follow-up the total fertility rate was only 7% lower than expected (RR 0.93, 95% CI, 0.84-1.03). The prevalence of assisted reproduction was 5.69% in the group of androgen users and 5.28% in the control group (P = 0.69). CONCLUSION: Androgen use was associated with a temporary decline in fertility and most androgen users achieved parenthood without any help from the health care system. Overall, the fertility rate and the prevalence of assisted reproduction among androgen users were close to those in the background population.

Androgen effect on body weight and behaviour of male and female rats: novel insight on the clinical value.

Androgenic-anabolic steroids (AASs) are synthetic derivative forms of the hormone testosterone. Sustanon® 250 solution for injection is one of those AASs that is used for low hormone levels and is self-administered for recreational purposes. This study was conducted to investigate the effects of sustanon on the body weight of male and female rats. Animals were injected different doses of sustanon (vehicle, 1, 3.2, 10, 32 and 100 mg/kg, I.M., once/week, for 6 weeks), and the weights for each animal were obtained. The rats were observed for agitated/aggressive behaviours every other day. In the present study, sustanon injections at 1, 3.2, 10, 32 and 100 mg/kg treatments did not alter body weight in male rats compared to the control group. However, moderately high and supraphysiological doses of sustanon (3.2, 10 and 32 mg/kg) resulted in a significant increase in body weight after 1 month of weekly treatment in female rats. Aggressive/agitated behaviours were observed only in female rats at the period of weight increase. In conclusion, different doses of sustanon did not alter the body weight in male rats after 6 weeks of treatment but doses of 3.2, 10 and 32 mg/kg resulted in a significant increase in body weight of female rats.

An uncommon lymphoma mimic: lipogranulomas.

A lipogranuloma is a complication of injecting exogenous oily composites, forming a nodule composed of foreign body histiocytes. These may be seen in the setting of use of anabolic steroids. We present a case of a 52-year-old male with rapidly growing intramuscular masses with accompanying lymphadenopathy and constitutional symptoms. A diagnosis of lymphoma was initially made in view of the multifocal nature of his disease. CT and PET/CT scans were used to profile the extent of disease. However, US-guided biopsy samples demonstrated acute-on-chronic fibro-inflammatory connective tissue, but no evidence of malignancy. A follow-up CT scan showed resolution of most of these masses. Subsequently, a history of self-injected anabolic steroids was obtained. Familiarity of imaging characteristics of lipogranuloma may be helpful in avoiding the pitfall of misdiagnosis in this clinical setting.

Evaluation of performance-enhancing drugs seized by Israeli enforcement agencies 2012-2017: implications for policy and regulatory change.

BACKGROUND: Illicit performance-enhancing substances are used mostly by athletes to enhance performance in sports, and by bodybuilders to gain muscle and body mass. Among performance-enhancing substances, the most common and known substances are anabolic-androgenic steroids, which are associated with a range of short and long-term adverse medical and psychiatric effects. While the sale and distribution of performance-enhancing substances are considered criminal offenses per the Israeli local pharmacy ordinance, the use and personal possession of these substances are not. Presently, the Division of Enforcement and Inspection of the Israel Ministry of Health cooperates with police and customs agents in performance-enhancing substance-related enforcement activities, which chiefly include seizures carried out at suspicious sites. Moreover, the Division of Enforcement and Inspection provides professional guidance, lab analysis services, and expert opinions on the toxicological and pharmaceutical nature of products seized. This paper presents a contemporary sub-analysis of registered seizures of performance-enhancing substances carried-out by Israel enforcement agencies. The main aim of this analysis is to characterize current patterns of performance-enhancing substances, thus providing the possibility of better assessment of current enforcement and health policy. METHODS: A sub-analysis of 712 seizures of performance-enhancing substances seized by Israeli enforcement authorities during a six-year period ranging from January 2012 to December 2017. RESULTS: This study demonstrates that Israel faces a challenge regarding the importation and distribution of illicit performance-enhancing substances. The most common substances seized were anabolic androgenic steroids (N = 539). Most seizures were carried out in the central mail processing sites, (38.4%), followed by seizures in private premises such as homes and warehouses (29.6%). Significant differences were found between anabolic-androgenic steroids and other substances, relating to place and year of seizure. Among seizures with known sources (N = 355), the most frequent geographic region given as the source of substances was Eastern Europe (47.6%), followed by East Asia (24.8%), West Asia (19.4%), and Western Europe (5.9%). Bulgaria was the country with the highest frequency of seizures (N = 71) followed by Jordan (N = 45), Thailand (N = 37) and Moldova (N = 36). Significant regional differences were found based on the variables of gender, place of seizure, and type of substance. The most frequent month of seizures was August (N = 129), followed by July (N = 119), and June (N = 118). CONCLUSIONS: While data analysis focused on the supply side of the performance-enhancing substances market, the high number of seizures of performance-enhancing substances in Israel represents evidence of the existence of a high demand and a large consumer base for these products. Consequently, there is a need for developing further enforcement, treatment, and prevention policies that do not currently exist in Israel. Policymakers should consider prioritizing law enforcement action and incentivizing intelligence sharing to monitor suspected shipment sources and specific points of entry. Additionally, the results demonstrate that there is a need in reforming the penal law to discourage the use of performance-enhancing substances. Similar measures have already been applied in countries like Spain, Italy, and Belgium. Furthermore, policy-makers should consider enhancing health ministry agencies with a higher enforcement capacity by giving them further investigative and inquiry authority. Due to the troubling magnitude of the phenomenon, policymakers should also prioritize educational and prevention strategies.

A photochemical approach to 18-nor-17ß-hydroxymethyl-17α-methylandrost-13-ene steroids.

A photochemical approach to 18-nor-17ß-hydroxymethyl-17α-methylandrost-13-ene unit of the long-term metabolites of 17-methylated androgenic anabolic steroids (AAS) is reported. It is based on a visible light-promoted radical decarboxylative alkynylation of steroidal redox-active ester. The developed method was used in synthesis of the long-term metabolite of AAS oxymesterone.
