Testosterone Imposters: An Analysis of Popular Online Testosterone Boosting Supplements

Social Perceptions of Masculinity and Sexual Esteem Are Impacted by Viagra Use, Testosterone, and Sexual Performance

Sexual behaviors play a role in the social construction of masculinity. Moreover, this stereotype has been capitalized upon by pharmaceutical companies, as well as those that sell products not approved by the U.S. Food and Drug Administration, for purposes of marketing sexual medicines. Stereotypical notions of masculinity, however, also emphasize the importance of self-reliance, which may cause some to look unfavorably upon the use of sexual medicine. Consistent with this notion, a male target was viewed as more masculine when his female partner consistently reached orgasm, unless he had no history of erectile dysfunction (ED), but was taking Viagra anyway (Experiment 1; N = 522). In addition, when his partner consistently reached orgasm, ratings of his sexual esteem were also lower if he used Viagra than if he did not, but only if he had no history of ED. In Experiment 2 (N = 711), although there was no effect of a male target's use of testosterone, social perception of his masculinity and sexual esteem increased as his "natural" levels of testosterone increased. In addition, exploratory analysis revealed that if the male target had low (but not normal or high) "natural" levels of testosterone, ratings of his masculinity were higher if his female partner consistently had an orgasm, which suggests that female orgasm served to "rescue" masculinity. Because expectations about drugs drive their use, it is important to address preconceived notions about the use of sexual medicines for purposes of enhancing masculinity and sexual esteem, as the social perception of their use is much more complex.

Do "testosterone boosters" really increase serum total testosterone? A systematic review

Testosterone boosters are heavily marketed on social media and marketplaces to men with claims to significantly increase testosterone. Lax industry regulation has allowed sales of supplements to thrive in the absence of verification of their purported benefits. Our primary objective was to systematically review all data published in the last two decades on testosterone boosters and determine their efficacy. Our outcome of interest was total testosterone increase versus placebo in four different populations: male athletes, men with late-onset hypogonadism infertile men and healthy men. Following search and screening, 52 studies were included in our review, relating to 27 proposed testosterone boosters: 10 studies of cholecalciferol; 5 zinc/magnesium; 4 Tribulus terrestris and creatine; 3 Eurycoma longifolia and Withania somnifera; 2 betaine, D-aspartic acid, Lepidium meyenii and isoflavones; while the remainder were single reports. Our findings indicate that most fail to increase total testosterone. The exceptions were β-hydroxy β-methylbutyrate and betaine, which can be considered effective for male athletes. Eurycoma longifolia, a blend of Punica granatum fruit rind and Theobroma cacao seed extracts (Tesnor™) and purified Shilajit extract (PrimaVie™) can be considered possibly effective for men with late-onset hypogonadism; Eurycoma longifolia and Withania somnifera possibly effective for healthy men; and a non-hormonal aromatase inhibitor (Novadex XT™) possibly effective for male athletes.

Effects of testosterone enanthate on aggression, risk-taking, competition, mood, and other cognitive domains during 28 days of severe energy deprivation

RATIONALE

Behavioral effects of testosterone depend on dose, acute versus sustained formulation, duration of administration, personality, genetics, and endogenous levels of testosterone. There are also considerable differences between effects of endogenous and exogenous testosterone.

OBJECTIVES

This study was the secondary behavioral arm of a registered clinical trial designed to determine if testosterone protects against loss of lean body mass and lower-body muscle function induced by a severe energy deficit typical of sustained military operations.

METHODS

Behavioral effects of repeated doses of testosterone on healthy young men whose testosterone was reduced by severe energy deficit were examined. This was a double-blind, placebo-controlled, between-group study. Effects of four weekly intramuscular injections of testosterone enanthate (200 mg/week, N = 24) or matching placebo (N = 26) were evaluated. Determination of sample size was based on changes in lean body mass. Tasks assessing aggression, risk-taking, competition, social cognition, vigilance, memory, executive function, and mood were repeatedly administered.

RESULTS

During a period of artificially induced, low testosterone levels, consistent behavioral effects of administration of exogenous testosterone were not observed.

CONCLUSIONS

Exogeneous testosterone enanthate (200 mg/week) during severe energy restriction did not reliably alter the measures of cognition. Study limitations include the relatively small sample size compared to many studies of acute testosterone administration. The findings are specific to healthy males experiencing severe energy deficit and should not be generalized to effects of other doses, formulations, or acute administration of endogenous testosterone or studies conducted with larger samples using tests of cognitive function designed to detect specific effects of testosterone.

Identifying Targets for Innovation in Amazon Reviews of Bedwetting Alarms: Thematic Analysis

BACKGROUND

Nocturnal enuresis (NE) is a frequent diagnosis in pediatric and adolescent populations with an estimated prevalence of around 15% at the age of 6 years. NE can have a substantial impact on multiple health domains. Bedwetting alarms, which typically consist of a sensor and moisture-activated alarm, are a common treatment.

OBJECTIVE

This study aimed to determine areas of satisfaction versus dissatisfaction reported by the parents and caregivers of children using current bedwetting alarms.

METHODS

Using the search term "bedwetting alarms" on the Amazon marketplace, products with >300 reviews were included. For each product, the 5 reviews ranked the "most helpful" for each star category were selected for analysis. Meaning extraction method was applied to identify major themes and subthemes. A percent skew was calculated by summing the total number of mentions of each subtheme,+1 for a positive mention, 0 for a neutral mention, and -1 for a negative mention, and dividing this total by the number of reviews in which that particular subtheme was observed. Subanalyses were performed for age and gender.

RESULTS

Of 136 products identified, 10 were evaluated based on the selection criteria. The main themes identified across products were long-term concerns, marketing, alarm systems, and device mechanics and features. The subthemes identified as future targets for innovation included alarm accuracy, volume variability, durability, user-friendliness, and adaptability to girls. In general, durability, alarm accuracy, and comfort were the most negatively skewed subthemes (with a negative skew of -23.6%, -20.0%, and -12.4% respectively), which are indicative of potential areas for improvement. Effectiveness was the only substantially positively skewed subtheme (16.8%). Alarm sound and device features were positively skewed for older children, whereas ease of use had a negative skew for younger children. Girls and their caretakers reported negative experiences with devices that featured cords, arm bands, and sensor pads.

CONCLUSIONS

This analysis provides an innovation roadmap for future device design to improve patient and caregiver satisfaction and compliance with bedwetting alarms. Our results highlight the need for additional options in alarm sound features, as children of different ages have divergent preferences in this domain. Additionally, girls and their parents and caretakers provided more negative overall reviews regarding the range of current device features compared to boys, indicating a potential focus area for future development. The percent skew showed that subthemes were often more negatively skewed toward girls, with the ease of use being -10.7% skewed for boys versus -20.5% for girls, and comfort being -7.1% skewed for boys versus -29.4% for girls. Put together, this review highlights multiple device features that are targets for innovation to ensure translational efficacy regardless of age, gender, or specific family needs.

The British Society for Sexual Medicine Guidelines on Male Adult Testosterone Deficiency, with Statements for Practice

Testosterone deficiency (TD) is an increasingly common problem with significant health implications, but its diagnosis and management can be challenging. A multi-disciplinary panel from BSSM reviewed the available literature on TD and provide evidence-based statements for clinical practice. Evidence was derived from Medline, EMBASE and Cochrane searches on hypogonadism, testosterone therapy (T Therapy) and cardiovascular safety from May 2017 to September 2022. This revealed 1,714 articles, including 52 clinical trials and 32 placebo-controlled randomised controlled trials. A total of twenty-five statements are provided, relating to five key areas: screening, diagnosis, initiating T Therapy, benefits and risks of T Therapy, and follow-up. Seven statements are supported by level 1 evidence, eight by level 2, five by level 3, and five by level 4. Recent studies have demonstrated that low levels of testosterone in men are associated with increased risk of incident type 2 diabetes mellitus, worse outcomes in chronic kidney disease and COVID 19 infection with increased all-cause mortality, along with significant quality of life implications. These guidelines should help practitioners to effectively diagnose and manage primary and age-related TD.

Cannabis and male sexual health: contemporary qualitative review and insight into perspectives of young men on the internet

INTRODUCTION

Cannabis use is increasing across the United States, yet its short- and long-term effects on sexual function remain controversial. Currently, there is a paucity of studies exploring the relationship between cannabis and men's health.

OBJECTIVES

To summarize the available literature on cannabis and men's health and provide insight into lay perceptions of this topic.

METHODS

We performed a qualitative PubMed review of the existing literature on cannabis and men's health according to the PRISMA guidelines. Separately, we analyzed relevant themes in online men's health forums. We utilized a Google cloud-based platform (BigQuery) to extract relevant posts from 5 men's health Reddit forums from August 2018 to August 2019. We conducted a qualitative thematic analysis of the posts and quantitatively analyzed them using natural language processing and a meaning extraction method with principal component analysis.

RESULTS

Our literature review revealed a mix of animal and human studies demonstrating the negative effects of cannabis on semen parameters and varying effects on erectile function and hormone levels. In our analysis of 372 686 Reddit posts, 1190 (0.3%) included relevant discussion on cannabis and men's health. An overall 272 posts were manually analyzed, showing that online discussions revolve around seeking answers and sharing the effects of cannabis on various aspects of sexual health and quality of life, often with conflicting experiences. Quantitative analysis revealed 1 thematic cluster related to cannabis, insecurity, and mental/physical health.

CONCLUSIONS

There is a limited number of quality human studies investigating the effects of cannabis on men's health. Men online are uncertain about how cannabis affects their sexual health and seek more information. As the prevalence of cannabis use increases, so does the need for research in this area.

Manipulation of Dietary Intake on Changes in Circulating Testosterone Concentrations

Elevations in the circulating concentration of androgens are thought to have a positive effect on the anabolic processes leading to improved athletic performance. Anabolic-androgenic steroids have often been used by competitive athletes to augment this effect. Although there has been concerted effort on examining how manipulating training variables (e.g., intensity and volume of training) can influence the androgen response to exercise, there has been much less effort directed at understanding how changes in both macronutrient and micronutrient intake can impact the androgen response. Thus, the focus of this review is to examine the effect that manipulating energy and nutrient intake has on circulating concentrations of testosterone and what the potential mechanism is governing these changes.

Testosterone Boosters Intake in Athletes: Current Evidence and Further Directions

“Testosterone boosters” (TB)—are supplements that are claimed to increase testosterone levels in the human body. While the consumption of TB may be popular among athletes, there is insufficient evidence both about the safety and the real efficacy of TB. In our review, we searched MEDLINE/PubMed and Cochrane Library for studies on the effects of 15 substances that are claimed to increase testosterone levels Anacyclus pyrethrum; Bulbine natalensis; Epimedium (horny goat weed); L-arginine; L-carnitine; magnesium; Mucuna pruriens; pantothenic acid; selenium; shilajit Eurycoma longifolia (Tongkat Ali); Serenoa repens (saw palmetto); boron; Withania somnifera (ashwagandha); and Trigonella foenum-graecum (fenugreek) in athletes and healthy adults under 55 years of age. We found such studies regarding 10 out of 15 substances: L-arginine (3 studies); L-carnitine (2); magnesium (1); selenium (2); shilajit (1); Tongkat Ali (2); Serenoa repens (1); boron (3); ashwagandha root (2); and fenugreek (7). Many of them fail to prove the efficacy of these substances to increase testosterone levels. Tongkat Ali, ashwagandha, and fenugreek were the substances with the strongest evidence. The positive effect of magnesium and shilajit on testosterone concentration was shown in single studies. Conflicting data found that L-arginine, L-carnitine, Serenoa repens, selenium and boron do not appear to increase testosterone levels. There are almost no data on the safety profile of various TB components; however, certain TB components may be linked to coagulation, and pancreatic and hepatic disorders. Based on the review, the authors conclude that at present TB cannot be recommended for use by athletes due to insufficient data on their efficacy and safety.

Risk Associated with the Use of Selected Ingredients in Food Supplements

This review focuses on four new product categories of food supplements: pre-workout, fat burner/thermogenic, brain/cognitive booster, and hormone/testosterone booster. Many food supplements have been shown to be contaminated with unauthorized substances. In some cases, the ingredients in the new categories of dietary supplements were medicinal products or new synthetic compounds added without performing clinical trials. Some of the new ingredients in dietary supplements are plant materials that are registered in the pharmacopoeia as herbal medicines. In other cases, dietary supplements may contain plant materials that have no history of human use and are often used as materials to 'camouflage' stimulants. In the European Union, new ingredients of dietary supplements, according to European Food Safety Authority or unauthorized novel food. Furthermore, selected ingredients in dietary supplements may be prohibited in sports and are recognized as doping agents by World Anti-Doping Agency.

Low Testosterone on Social Media: Application of Natural Language Processing to Understand Patients' Perceptions of Hypogonadism and Its Treatment

BACKGROUND

Despite the results of the Testosterone Trials, physicians remain uncomfortable treating men with hypogonadism. Discouraged, men increasingly turn to social media to discuss medical concerns.

OBJECTIVE

The goal of the research was to apply natural language processing (NLP) techniques to social media posts for identification of themes of discussion regarding low testosterone and testosterone replacement therapy (TRT) in order to inform how physicians may better evaluate and counsel patients.

METHODS

We retrospectively extracted posts from the Reddit community r/Testosterone from December 2015 through May 2019. We applied an NLP technique called the meaning extraction method with principal component analysis (MEM/PCA) to computationally derive discussion themes. We then performed a prospective analysis of Twitter data (tweets) that contained the terms low testosterone, low T, and testosterone replacement from June through September 2019.

RESULTS

A total of 199,335 Reddit posts and 6659 tweets were analyzed. MEM/PCA revealed dominant themes of discussion: symptoms of hypogonadism, seeing a doctor, results of laboratory tests, derogatory comments and insults, TRT medications, and cardiovascular risk. More than 25% of Reddit posts contained the term doctor, and more than 5% urologist.

CONCLUSIONS

This study represents the first NLP evaluation of the social media landscape surrounding hypogonadism and TRT. Although physicians traditionally limit their practices to within their clinic walls, the ubiquity of social media demands that physicians understand what patients discuss online. Physicians may do well to bring up online discussions during clinic consultations for low testosterone to pull back the curtain and dispel myths.

A systematic review and evidence-based analysis of ingredients in popular male testosterone and erectile dysfunction supplements

The objective was to study available evidence for ingredients of popular over-the-counter testosterone and erectile dysfunction (ED) supplements. The top 16 male testosterone and 16 ED supplements in the USA were identified from the most popular online retailers: A1 Supplements, Amazon, Vitamin Shoppe, and Walmart. In total, 37 ingredients were identified and PUBMED online database was reviewed for randomized-controlled trials (RCT) studying their efficacy. Ingredients were categorized based on evidence quantity using an adapted version of the American Heart Association scoring system. In total, 16 ingredients from testosterone supplements and 21 from ED supplements were identified. Tribulus, Eurycoma longifolia, Zinc, L-arginine, Aspartate, Horny goat weed, and Yohimbine were most common. In all, 105 RCTs studying the identified ingredients were found. No whole supplement products have published RCT evidence. 19% of ingredients received an A grade for strong positive evidence with net positive evidence in two or more RCTs. In total, 68% received C or D grades for contradicting, negative, or lacking evidence. Overall, 69% of ingredients in testosterone supplements and 52% of ingredients in ED supplements have published RCT evidence. Many male supplements claim to improve testosterone or ED parameters; however, there is limited evidence, which should be considered when counseling patients.

Efficacy and Safety of Common Ingredients in Aphrodisiacs Used for Erectile Dysfunction: A Review

INTRODUCTION

Erectile dysfunction (ED) is the inability to attain or sustain an erection for sexual intercourse. Affected men endorse difficulties with intimacy and feelings of guilt and shame. Although medical treatments are available, patients are reluctant to discuss ED with physicians and often use dietary supplements to attempt to treat their ED. As such, there is a need to better understand the effects of ingredients used in nutraceuticals for ED treatment.

OBJECTIVES

To summarize the literature on the efficacy and safety of the most common ingredients used in ED supplements.

METHODS

10 of the most common ingredients in ED supplements were reviewed using PubMed-indexed literature to assess their efficacy and safety in treating ED. Key findings were summarized to include historical use, active ingredients, prior animal studies, human studies, and toxicity.

RESULTS

Nutraceuticals used in ED treatment include a variety of ingredients. Although L-arginine is a safe supplement with clinical data supporting improved erectile function, limited data exist on the efficacy of other ingredients in the treatment of ED.

CONCLUSION

Despite the growing use of supplements for treatment of sexual dysfunction, ED supplements remain poorly studied, with limited data demonstrating efficacy of individual ingredients. Further study is required to definitively determine the efficacy of nutraceuticals in ED treatment. Srivatsav A, Balasubramanian A, Pathak UI, et al.

Non-testosterone management of male hypogonadism: an examination of the existing literature

Testosterone deficiency is defined as a total testosterone level <300 ng/dL confirmed on two early morning lab draws. Testosterone therapy has historically been offered to men with symptomatic testosterone deficiency in the form of injections, gels, or pellets. However, these treatments are invasive or have undesirable effects including the risk of drug transference. Additionally, testosterone therapy has been associated with increases in hematocrit and controversy remains regarding the risk of cardiovascular and thromboembolic events while on testosterone therapy. As such, much interest has recently been focused on alternative treatment options for testosterone deficiency in the form of orally-administered medications with more favorable side effect profiles. Lifestyle modifications and varicocelectomy have been shown to raise endogenous testosterone production. Similarly, SERMs and aromatase inhibitors (AIs) have been shown to raise testosterone levels safely and effectively. Human chorionic gonadotropin (hCG) remains the only FDA-approved non-testosterone treatment option for testosterone deficiency in men. However, this medication is expensive and requires patient-administered injections. Over the counter herbal supplements and designer steroids remain available though they are poorly studied and are associated with the potential for abuse as well as increased hepatic and cardiovascular risks. This review aims to discuss the existing treatment alternatives to traditional testosterone therapy, including efficacy, safety, and side effects of these options. The authors suggest that the SERM clomiphene citrate (CC) holds the greatest promise as a non-testosterone treatment option for testosterone deficiency.

A review of the evolving landscape between the consumer Internet and men's health

Internet adoption continues to increase as broadband access and mobile connectivity penetrate developing global markets. Alongside increasing adoption, the Internet continues to evolve and usher in new modes of user interaction. Social media and search engines have facilitated the emergence of the participatory web, in which users are able to contribute content, form online communities, and disseminate information. This participatory web is reshaping the patient-physician relationship as patients are able to search for medical information, directly engage with healthcare practitioners through social media, and make therapeutic decisions via online marketplaces. The ability for patients to self-diagnose and self-treat is highly relevant to andrology, given that men have a baseline reluctance to visit healthcare providers. Furthermore, men’s health issues such as erectile dysfunction and male infertility are stigmatized, with men turning to the Internet for guidance. The focus of this review is to survey the academic literature that evaluates the quality of online content for four common men’s health conditions: hypogonadism, male infertility, erectile dysfunction, and Peyronie’s disease.
