Androgen Society Position Paper on Cardiovascular Risk With Testosterone Therapy.

The Androgen Society is an international, multidisciplinary medical organization committed to advancing research and education in the field of testosterone deficiency and testosterone therapy (TTh). This position paper is written in response to results of the TRAVERSE study, published in June 2023, which reported no increased risk of major adverse cardiovascular events (MACE) in men who received TTh compared with placebo. In 2013-2014, 2 observational studies reported increased cardiovascular (CV) risks with TTh and received wide media attention. Despite strong criticism of those 2 studies, in 2015, the Food and Drug Administration added a CV warning to testosterone product labels and required pharmaceutical companies to perform a CV safety study, which became the TRAVERSE trial. TRAVERSE enrolled 5246 men at high risk for MACE based on existing heart disease or multiple risk factors. Participants were randomized to daily testosterone gel or placebo gel, with a mean follow-up of 33 months. Results revealed no greater risk of MACE (myocardial infarction, stroke, or CV death) or venothrombotic events in men who received TTh compared with placebo. Review of the prior literature reveals near uniformity of studies reporting no increased MACE with TTh. This includes 2 additional large randomized controlled trials, multiple smaller randomized controlled trials, several large observational studies, and 19 meta-analyses. In view of these findings, it is the position of the Androgen Society that it has now been conclusively determined that TTh is not associated with increased risks of heart attack, stroke, or CV death.

Development of a comprehensive open access "molecules with androgenic activity resource (MAAR)" to facilitate risk assessment of chemicals.

The increasing prevalence of endocrine-disrupting chemicals (EDCs) and their potential adverse effects on human health underscore the necessity for robust tools to assess and manage associated risks. The androgen receptor (AR) is a critical component of the endocrine system, playing a pivotal role in mediating the biological effects of androgens, which are male sex hormones. Exposure to androgen-disrupting chemicals during critical periods of development, such as fetal development or puberty, may result in adverse effects on reproductive health, including altered sexual differentiation, impaired fertility, and an increased risk of reproductive disorders. Therefore, androgenic activity data is critical for chemical risk assessment. A large amount of androgenic data has been generated using various experimental protocols. Moreover, the data are reported in different formats and in diverse sources. To facilitate utilization of androgenic activity data in chemical risk assessment, the Molecules with Androgenic Activity Resource (MAAR) was developed. MAAR is the first open-access platform designed to streamline and enhance the risk assessment of chemicals with androgenic activity. MAAR's development involved the integration of diverse data sources, including data from public databases and mining literature, to establish a reliable and versatile repository. The platform employs a user-friendly interface, enabling efficient navigation and extraction of pertinent information. MAAR is poised to advance chemical risk assessment by offering unprecedented access to information crucial for evaluating the androgenic potential of a wide array of chemicals. The open-access nature of MAAR promotes transparency and collaboration, fostering a collective effort to address the challenges posed by androgenic EDCs.

Addition of testosterone to endocrine care for transgender women: a dose-finding and feasibility trial.

OBJECTIVE: Transgender women who underwent gonadectomy have lower serum testosterone concentrations than cisgender women. There is uncertainty regarding the dosing and side effects of supplementation of testosterone in transgender women. This study aimed to assess the feasibility of dosing testosterone to the cisgender female physiological range in transgender women. In addition, we explored changes in cardiovascular parameters, virilizing side effects, and clinical symptoms. DESIGN: This is an open-label, single-arm feasibility study. Participants initially went through a dose-titration phase with 2-week intervals of 0.07-0.09-0.13 mL (277-318-403 µg bioavailable testosterone) testosterone 2% gel to establish a dose leading to serum testosterone concentrations between 1.5 and 2.5 nmol/L. This dose was then continued for 8 weeks. METHODS: Participants applied daily transdermal testosterone 2% gel (Tostran®) at the prescribed dosage. Testosterone was measured every 2-4 weeks. Laboratory analyses, side effects, and clinical symptoms were evaluated. RESULTS: In total, 12 participants were included. Most participants required a dose of 0.07 mL (277 µg bioavailable testosterone) or 0.09 mL (318 µg bioavailable testosterone) to reach serum testosterone concentrations of 1.5-2.5 nmol/L. Continuing this dose, testosterone concentrations remained stable throughout the study. Changes in clinical outcomes were in the desired direction, and side effects were mild. CONCLUSIONS: The use of testosterone supplementation in transgender women seems feasible and safe in the short term. Although dosing requires personalized titration, stable testosterone levels can be established. A blinded, placebo-controlled, randomized clinical trial is needed to study the clinical benefit.

Impaired vascular function among young users of anabolic-androgenic steroids.

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

Testosterone and other treatments for transgender males and non-binary trans masculine individuals.

Testosterone therapy is the main hormonal treatment offered in transmen to alleviate somatic gender dysphoria. Testosterone can be administered via topical or injectable preparations to achieve physical changes resulting in masculinisation and improve quality of life for the treated individuals. The aim of our paper is to outline methods for testosterone replacement, their impact on main body systems of transmen, potential associated health risks and long term follow up. Androgen use in transgender medicine is safe with appropriate endocrine guidance and monitoring. Studies with longer follow-up period, including those who may prefer low dose testosterone, interested in pregnancy or older people may further improve the management of female-to-male transgender persons.

Androgen abuse: Risks and adverse effects in men.

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

Testosterone: A Review for Orthopaedic Surgeons.

¼ Testosterone replacement treatment (TRT) and anabolic androgenic steroid (AAS) use is common and possibly increasing.¼ Diagnosing and treating hypogonadism in men is controversial.¼ Hypogonadism and the use of AASs seem to have a detrimental effect on the musculoskeletal system. The current literature on TRT and the musculoskeletal system shows an increased risk of tendon injury.¼ There may be a role for testosterone supplementation in the postoperative period.

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

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

Development of new hormonal male contraception for the couple.

BACKGROUND: Current options for male contraception are limited to condoms, the withdrawal method, or a vasectomy. Studies indicate that men have expressed growing interest in bearing responsibility for family planning. OBJECTIVES: To review prior studies investigating the role of an androgen-only or androgen with progestin regimen for hormonal male contraception and to provide an update of a promising new hormonal agent, a transdermal gel. DISCUSSION: Thus far, there have been six studies conducted in couples evaluating the contraceptive efficacy of an androgen-only or androgen co-administered with a progestin regimen for hormonal male contraception. The only ongoing study is by the National Institute of Child Health and Human Development, in collaboration with the Population Council. They have developed a novel transdermal gel containing testosterone and segesterone acetate (Nestorone), a progestin. An ongoing phase II study enrolling more than 460 couples has shown great potential with respect to the product's efficacy, safety, reversibility, and acceptability. As this agent advances in development, a rapid at-home test for sperm concentration will provide couples with immediate feedback regarding their potential for pregnancy. CONCLUSION: There is promise for the first-of-its-kind hormonal male contraceptive, a transdermal gel, to achieve market approval for distribution in the United States and elsewhere. Its safety, efficacy, reversibility, and user-control are all appealing qualities that make it readily adoptable for clinical practice.

Exploring Anabolic Androgenic Steroid Use Among Cisgender Gay, Bisexual, and Queer Men.

Importance: Anabolic androgenic steroids (AAS) are disproportionately used by sexual minority men, with the physical and mental health implications of AAS use incompletely understood. Objective: To understand the reasons for use and health care needs of gay, bisexual, and queer cisgender men using AAS. Design, Setting, and Participants: This qualitative study was conducted from November 2021 to May 2023 using self-administered questionnaires and semistructured interviews that were transcribed and coded using reflexive thematic analysis. Participants were recruited through convenience and snowball sampling from lesbian, gay, bisexual, transgender, and queer clinical centers in New York, New York, as well as through online platforms. All patients self-identified as cisgender and gay, bisexual, or queer. Exposures: History of nonprescribed AAS use for a minimum of 8 consecutive weeks was required. Main Outcomes and Measures: The primary outcomes were reasons for and health implications of AAS use and interactions with health care practitioners, as determined through interviews. Interview transcripts were collected and analyzed. Results: Thematic saturation was reached after interviews with 12 male participants (mean [SD] age, 44 [11] years), with the majority of participants identifying as gay (10 participants [83%]), White non-Hispanic (9 participants [75%]), being in their 30s and 40s (9 participants [75%]), holding a bachelor's degree or higher (11 participants [92%]), and having used steroids for a mean (SD) of 7.5 (7.1) years. One participant (8%) self-identified as Black, and 2 (17%) identified as Hispanic. Seven men (58%) met the criteria for muscle dysmorphia on screening. Nine overarching themes were found, including internal and external motivators for initial use, continued use because of effectiveness or fear of losses, intensive personal research, physical and emotional harms experienced from use, using community-based harm reduction techniques, frustration with interactions with the medical community focused on AAS cessation, and concerns around the illegality of AAS. Conclusions and Relevance: In this qualitative study, AAS use among cisgender gay, bisexual, and queer men was found to be associated with multifactorial motivators, including a likely AAS use disorder and muscle dysmorphia. Despite all participants experiencing harms from use, men seeking medical help found insufficient support with practitioners insistent on AAS cessation and, thus, developed their own harm reduction techniques. Further research is needed to assess the utility of practitioner education efforts, the safety and efficacy of community-developed harm reduction methods, and the impact of AAS decriminalization on health care outcomes for this patient population.

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

INTRODUCTION: The use of androgenic anabolic steroids (AASs) among recreational athletes is steadily increasing. However, knowledge regarding the potentially harmful effects of AAS primarily originates from case reports and small observational studies. This large-scale study aims to investigate the impact of AAS use on vascular plaque formation, preclinical coronary disease, cardiac function, circulating cardiovascular risk markers, quality of life (QoL) and mental health in a broad population of illicit AAS users. METHODS AND ANALYSES: A nationwide cross-sectional cohort study including a diverse population of men and women aged ≥18 years, with current or previous illicit AAS use for at least 3 months. Conducted at Odense University Hospital, Denmark, the study comprises two parts. In part A (the pilot study), 120 recreational athletes with an AAS history will be compared with a sex-matched and age-matched control population of 60 recreational athletes with no previous AAS use. Cardiovascular outcomes include examination of non-calcified coronary plaque volume and calcium score using coronary CT angiography, myocardial structure and function via echocardiography, and assessing carotid and femoral artery plaques using ultrasonography. Retinal microvascular status is evaluated through fundus photography. Cardiovascular risk markers are measured in blood. Mental health outcomes include health-related QoL, interpersonal difficulties, body image concerns, aggression dimensions, anxiety symptoms, depressive severity and cognitive function assessed through validated questionnaires. The findings of our comprehensive study will be used to compose a less intensive investigatory cohort study of cardiovascular and mental health (part B) involving a larger group of recreational athletes with a history of illicit AAS use. ETHICS AND DISSEMINATION: The study received approval from the Regional Committee on Health Research Ethics for Southern Denmark (S-20210078) and the Danish Data Protection Agency (21/28259). All participants will provide signed informed consent. Research outcomes will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER: NCT05178537.

Prenatal Androgen Exposure Induces Anxiety-Like Behavior in Ewes.

INTRODUCTION: In humans, prenatal androgen excess can lead to a broad spectrum of pathologies in adulthood, including polycystic ovary syndrome (PCOS). Women with PCOS present a variety of reproductive and metabolic disturbances and they also face increased risk to develop neuropsychiatric disorders such as depression and anxiety. Despite the high prevalence, the cause of depressive and anxiety symptoms is not fully elucidated. The use of androgenized ewe models can provide valuable insights into the pathogenesis of PCOS, as they closely mimic the reproductive, neuroendocrine, and metabolic characteristics observed in women with this condition. METHOD: We studied the impact of prenatal exposure to testosterone propionate on cognitive and behavioral performances of Ile-de-France ewes, using a plethora of behavioral tests for anxiety and cognitive performances. RESULTS: Our findings indicate that prenatal androgenized ewes exhibit markedly elevated levels of anxiety-like behavior compared to control animals, while showing no discernible differences in cognitive performance. CONCLUSION: These discoveries offer novel perspectives on how maternal androgen excess contributes to anxiogenic effects in PCOS preclinical models, underscoring the ewe's significance as a model for conducting mechanistic studies to unravel the physiological and molecular aspects of anxiety.

Anabolic-Androgenic Steroid Abuse Causes Cardiac Dysfunction.

This article aims to review available literature evidence about the harmful effects of long-term anabolic-androgenic steroid (AAS) abuse on the heart. A review of 11 existing literature articles regarding this association has been used in the development of this review article. There is increasing medical literature documentation of the eventual harmful effect of AAS misuse or abuse on the heart. Individuals who misuse these steroids are susceptible to significant debilitation and loss of productive person-hours, and in severe cases, it can lead to death. Raising awareness about this potentially deleterious effect of anabolic steroids is crucial to prevent its misuse or abuse.

The effect of anabolic androgenic steroids on heart rate recovery index and electrocardiographic parameters in male bodybuilders.

BACKGROUND: The control of the cardiovascular system depends on the autonomic nerve system. Chronic anabolic andorogenic steroids (AAS) use causes sympathovagal imbalance and increases sympathetic nerve activity. OBJECTIVE: The reduction in heart rate from the peak exercise rate following the end of the exercise stress test is known as the heart rate recovery index (HRRI). Several methods have been utilized to assess myocardial repolarization, such as QT interval (QT), corrected QT interval (QTc), and T-wave peak-to-end interval (Tp-e interval). Based on a growing number of data a higher Tp-e/QT ratio is linked to malignant ventricular arrhythmias, and an increased Tp-e interval may correlate with the transmural dispersion of repolarization. Our hypothesis is that the use of chronic AAS was decrease HRRI during maximal exercise and increased risk of cardiac arrhythmias and sudden cardiac death. METHODS: This study included 44 male bodybuilders, with an average age of 29.7 ± 8.14 years, divided into AAS abuse [AAS users (n = 21) and AAS nonuser (n = 23)]. RESULTS: The first (p = 0.001) and second minute (p = 0.001) HRRI of the subjects with AAS users were significantly lower than those of the control group. Additionally, HRRI after the third (p = 0.004) and fifth minutes (p = 0.007) of the recovery period were significantly lower in AAS group compared with the control group. Who used AAS had significantly higher QT, QTc, Tp-e, Tp-e/QT, and Tp-e/QTc values than non-users (all p = 0.001). CONCLUSIONS: Chronic AAS use has been shown to cause sympathetic dominance, which may be a pro arrhythmic state.

Acetate ameliorates ovarian mitochondrial dysfunction in letrozole-induced polycystic ovarian syndrome rat model by improving mitofusin-2.

Androgen excess and metabolic abnormality largely contribute to the pathogenesis of polycystic ovarian syndrome (PCOS), which primarily precipitates ovarian dysfunction and infertility in reproductive-age women. Impaired mitochondrial function and epigenetic alteration have been linked to the development of PCOS. However, it is unknown whether acetate would exert a therapeutic effect on ovarian mitochondrial dysfunction in PCOS. Herein, the study hypothesized that acetate reverses ovarian mitochondrial dysfunction in experimental PCOS rat model, possibly through modulation of mitofusin-2 (MFn2). Eight-week-old female Wistar rats were randomized into four groups (n = 5). Induction of PCOS was performed by 1 mg/kg letrozole (p.o.), administered for 21 days. Thereafter, the rats were treated with acetate (200 mg/kg; p.o.) for 6 weeks. The PCOS rats demonstrated androgen excess, multiple ovarian cysts, elevated anti-mullerian hormone and leptin and decreased SHBG, adiponectin and 17-ß estradiol with corresponding increase in ovarian transforming growth factor-ß1. Additionally, inflammation (tumor growth factor and nuclear factor-kB), elevated caspase-6, decreased hypoxia-inducible factor-1α and elevated histone deacetylase-2 (HDAC2) were observed in the ovaries of PCOS rats, while mitochondrial abnormality with evidence of decreased adenosine triphosphate synthase and MFn2 was observed in rats with PCOS. Treatment with acetate reversed the alterations. The present results collectively suggest that acetate ameliorates ovarian mitochondrial abnormality, a beneficial effect that is accompanied by MFn2 with consequent normalization of reproductive-endocrine profile and ovarian function. Perhaps, the present data provide hope for PCOS individuals that suffer infertility.

Mortality Among Users of Anabolic Steroids.

This cohort study investigates mortality and cause of death among a large cohort of androgenic anabolic steroid users, compared with a control group, in Denmark from January 3, 2006, to March 1, 2018.

Cardiovascular safety of testosterone replacement therapy in men: an updated systematic review and meta-analysis.

INTRODUCTION: The cardiovascular (CV) safety of testosterone (T) replacement therapy (TRT) is still conflicting. Recent data suggested a TRT-related increased risk of atrial fibrillation (AF). The aim of this study was to systematic review and meta-analyze CV risk related to TRT as derived from placebo controlled randomized trials (RCTs). AREAS COVERED: An extensive Medline, Embase, and Cochrane search was performed. All placebo-controlled RCTs reporting data on TRT-related CV safety were considered. To better analyze the role of T on AF, population-based studies investigating the relationship between endogenous circulating T levels and AF incidence were also included and analyzed. EXPERT OPINION: Out of 3.615, 106 studies were considered, including 8.126 subjects treated with TRT and 7.310 patients allocated to placebo. No difference between TRT and placebo was observed when major adverse CV events were considered. Whereas the incidence of non-fatal arrhythmias and AF was increased in the only trial considering CV safety as the primary endpoint, this was not confirmed when all other studies were considered (MH-OR 1.61[0.84;3.08] and 1.44[0.46;4.46]). Similarly, no relationship between endogenous T levels and AF incidence was observed after the adjustment for confounders Available data confirm that TRT is safe and it is not related to an increased CV risk.

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.
