Use, Misuse and Abuse of Testosterone and Other Androgens.

INTRODUCTION: For several decades, testosterone and its synthetic derivatives have been used for anabolic and androgenic purposes. Initially restricted to professional bodybuilders, these substances gradually became more popular with recreational weightlifters. Considering its increasing prevalence, the consumption of anabolic androgenic steroids (AAS) has become a matter of great concern. Although most side effects are mild and reversible, some of them can cause permanent damage or can be potentially life threatening. OBJECTIVES: To review and summarize medical literature regarding misuse and abuse of testosterone and other androgens, in order to provide evidence-based information on the main topics related to this subject, such as how to identify and how to deal with these patients, and to elucidate the multiple possible adverse effects secondary to this practice. METHODS: Key studies were retrieved from PubMed (1989-2021) with reference searches from relevant articles. Search terms included "hypogonadism", "anabolic androgenic steroids", "androgens", "misuse AND testosterone", "abuse AND testosterone", and "side effects AND testosterone". RESULTS: There is a significant lack of information in the peer-reviewed literature describing demographic data, implications for different organ systems and the management of current or former AAS users; however, androgen abuse has been already linked to a wide variety of cardiovascular diseases, metabolic, endocrine, neurological, psychiatric and liver disorders. Despite all this, most physicians still feel uncomfortable and hesitate to discuss the issue with patients. CONCLUSIONS: The chronic use of high doses of AAS is associated with adverse effects in several organ systems; however, there are still many gaps in our knowledge about the long-term consequences of this practice and how to deal with these patients. Healthcare professionals have a crucial role in combating this public health problem, recognizing and preventing the spread of androgen abuse.

Educational program on sexual medicine for medical students: pilot project in Brazil.

BACKGROUND: Little is known about the factors that influence the graduation of medical students in relation to the preparation of their approach to sexual health care. Teaching hours for sexual education in undergraduate medical courses are frequently insufficient to prepare them for their roles to treat this complex issue. This study aimed to evaluate the delivery of sexual education to medical students by assessing their knowledge, attitudes, and self-confidence to treat patients. METHODS: A 1-day course was organized to tackle the main concerns of patients in respect to sexual health problems. The course was comprised of classes and time for students to discuss doubts with specialists. At the end of the course the knowledge of students on the subject and their confidence to care for patients with concerns on sexual issues were evaluated. RESULTS: Seventy-four medical students participated in the 1-day educational program on sexual medicine that included lectures about different topics and discussion. At the end of the course, students answered questionnaires about how the course had possibly improved their confidence regarding dealing with sexual issues. The analysis of the opinions of the students suggested an improvement in self-confidence with regard to discussing sexual behavior with patients. CONCLUSIONS: The results demonstrated a necessity to increase knowledge and stimulate positive attitudes of students about sexuality thereby improving their ability to treat patients with sexuality problems.

Fundamental Concepts Regarding Testosterone Deficiency and Treatment: International Expert Consensus Resolutions.

To address widespread concerns regarding the medical condition of testosterone (T) deficiency (TD) (male hypogonadism) and its treatment with T therapy, an international expert consensus conference was convened in Prague, Czech Republic, on October 1, 2015. Experts included a broad range of medical specialties including urology, endocrinology, diabetology, internal medicine, and basic science research. A representative from the European Medicines Agency participated in a nonvoting capacity. Nine resolutions were debated, with unanimous approval: (1) TD is a well-established, clinically significant medical condition that negatively affects male sexuality, reproduction, general health, and quality of life; (2) symptoms and signs of TD occur as a result of low levels of T and may benefit from treatment regardless of whether there is an identified underlying etiology; (3) TD is a global public health concern; (4) T therapy for men with TD is effective, rational, and evidence based; (5) there is no T concentration threshold that reliably distinguishes those who will respond to treatment from those who will not; (6) there is no scientific basis for any age-specific recommendations against the use of T therapy in men; (7) the evidence does not support increased risks of cardiovascular events with T therapy; (8) the evidence does not support increased risk of prostate cancer with T therapy; and (9) the evidence supports a major research initiative to explore possible benefits of T therapy for cardiometabolic disease, including diabetes. These resolutions may be considered points of agreement by a broad range of experts based on the best available scientific evidence.

Efficacy and tolerability of lodenafil carbonate for oral therapy of erectile dysfunction: a phase III clinical trial.

INTRODUCTION: This is a phase III, prospective, randomized, double-blind, placebo-controlled clinical trial on lodenafil carbonate (LC), a novel phosphodiesterase 5 inhibitor developed in Brazil. AIM: Expanding information on LC efficacy and safety. MAIN OUTCOME MEASURES: International Index of Erectile Function (IIEF) erectile domain, positive answers to the sexual encounter profile (SEP)-2 and SEP-3 questions and incidence of adverse events (AEs). METHODS: A total of 350 men with erectile dysfunction (ED) of all degrees were randomized to placebo, LC 40 mg or LC 80 mg and followed for 4 weeks. They completed the IIEF and answered the SEP questions 2 and 3 after each intercourse without and with the use of LC. RESULTS: IIEF Erectile Domain scores without and with the use of medication were the following (mean [M] +/- standard deviation [SD]): placebo = 13.9 +/- 5.2 and 14.8 +/- 7.8; LC 40 mg = 13.6 +/- 5.3 and 18.6 +/- 8.0; LC 80 mg = 13.4 +/- 4.9 and 20.6 +/- 7.7 (analysis of variance [ANOVA] P < 0.01). Positive answers to SEP-2 without and with the use of medication were the following (M +/- SD): placebo = 55.3 +/- 43.2% and 52.1 +/- 41.4%; LC 40 mg = 46.4 +/- 44.3% and 63.5 +/- 42.0%; LC 80 mg = 50.2 +/- 40.9% and 80.8 +/- 32.3% (ANOVA P < 0.01). Positive answers to SEP-3 were the following: placebo = 20.2 +/- 32.3% and 29.7 +/- 38.1%; LC 40 mg = 19.6 +/- 34.3% and 50.8 +/- 44.4%; LC 80 mg = 20.8 +/- 33.2% and 66.0 +/- 39.3% (ANOVA P < 0.01). The patients with at least one AE were placebo = 28.7%, LC 40 mg = 40.9%, and LC 80 mg = 49.5%. AEs whose incidence was significantly higher with LC than with placebo included rhinitis, headache, flushing, visual disorder, and dizziness. CONCLUSIONS: LC showed a satisfactory efficacy-safety profile for oral therapy of ED.

Efficacy and safety of tadalafil in the treatment of Latin American men with erectile dysfunction: results of integrated analyses.

INTRODUCTION: Available information on the efficacy and safety of tadalafil on Latin American men comes from reports where data is mixed with other populations. AIM: To assess the efficacy and safety of tadalafil in Latin American men with erectile dysfunction (ED). METHODS: Integrated analyses of data from four 12-week, randomized, double-blind, parallel, placebo-controlled trials conducted in Latin America that assessed the efficacy and safety of tadalafil in 406 Latin American men with ED of diverse etiology and severity assigned to placebo (N = 113), 10-mg tadalafil (N = 39), or 20-mg tadalafil (N = 254). MAIN OUTCOME MEASURES: Efficacy was assessed by International Index of Erectile Function Erectile Function (IIEF-EF) domain, questions 2 to 5 of the Sexual Encounter Profile and the first Global Assessment Question. Adverse events (AEs) reported by all enrolled patients were collected. RESULTS: Latin American patients treated with 10 or 20 mg of tadalafil had a significant mean improvement of 4.92 and 9.78, respectively, in the IIEF-EF domain score from baseline compared with 2.24 on placebo (P = 0.003 and P < 0.001, respectively, vs. placebo). At both doses, the mean success rate for penetration was 75 and 86%, respectively, compared with 56% on placebo (P < or = 0.001), the mean success rate for intercourse was 55% and 78%, compared with 36% on placebo (P < 0.001 vs. placebo), and 62% and 91% of patients, respectively, reported improved erections at the end point, vs. 43% on placebo (P = 0.160 and P < 0.001, respectively, vs. placebo). The most frequent AEs were headache, dyspepsia, and back pain. CONCLUSIONS: 10 or 20 mg tadalafil was an effective, safe, and well-tolerated therapy for Latin American men with ED of diverse etiology despite of ED severity.

Efficacy of tadalafil in men with erectile dysfunction naïve to phosphodiesterase 5 inhibitor therapy compared with prior responders to sildenafil citrate.

INTRODUCTION: Tadalafil, an inhibitor of phosphodiesterase 5 (PDE5), is indicated for treatment of erectile dysfunction. Most tadalafil clinical trials excluded patients with unsuccessful prior treatment with sildenafil citrate (sildenafil). AIM: This retrospective analysis of pooled data from 14 tadalafil clinical trials examines the effect of this exclusion by comparing efficacy results in 1,349 patients without prior sildenafil use (naïve, presumably a mixture of potential responders and nonresponders) with efficacy results in 1,440 patients previously responsive to sildenafil (prior responders). MAIN OUTCOME MEASURES: Efficacy measures included the International Index of Erectile Function (IIEF) erectile function (EF) domain, overall satisfaction (OS), and intercourse satisfaction (IS) domain scores; Sexual Encounter Profile (SEP) diary questions 2 through 5 (SEP2 [successful penetration], SEP3 [successful intercourse], SEP4 (satisfaction with hardness of erection), and SEP5 [overall satisfaction with the sexual experience]); and a Global Assessment Question (GAQ1) (13/14 trials) about erection improvement. Efficacy was compared using analysis of covariance (IIEF and SEP) and logistic regression (GAQ1) models. METHODS: After a 4-week, treatment-free, run-in period, patients in 14 double-blind, placebo-controlled, parallel-group trials were treated with tadalafil 10 mg, tadalafil 20 mg, or placebo for 12 weeks (dosed as needed before sexual activity, no more than once daily). RESULTS: Tadalafil improved erectile function compared with placebo (P < 0.001) in naïve patients and sildenafil prior responders for all efficacy measures. For most efficacy outcomes, responses in the naïve group (probable mix of responders and nonresponders) were not statistically different from responses in the prior-responder group (P >or= 0.10). CONCLUSIONS: The similar responses of these two patient groups observed in this post hoc analysis suggest, but do not confirm, that exclusion of sildenafil nonresponders in previously reported tadalafil clinical trials may not have substantially affected efficacy outcomes. Tadalafil improved erectile function in patients naïve to PDE5 inhibitor therapy and in patients who previously responded to sildenafil therapy.

Endocrine aspects of sexual dysfunction in men.

INTRODUCTION: Endocrine disorders of sex steroid hormones may adversely affect men's sexual function. Aim. To provide expert opinions/recommendations concerning state-of-the-art knowledge for the pathophysiology, diagnosis and treatment of endocrinologic sexual medicine disorders. METHODS: An International Consultation in collaboration with the major urology and sexual medicine associations assembled over 200 multidisciplinary experts from 60 countries into 17 committees. Committee members established specific objectives and scopes for various male and female sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respective sexual medicine topic represent the opinion of experts from five continents developed in a scientific and debate process. Concerning the Endocrine committee, there were eight experts from seven countries. MAIN OUTCOME MEASURE: Expert opinions/recommendations are based on grading of evidence-based medical literature, extensive internal committee discussion over 2 years, public presentation and deliberation. RESULTS: Hypogonadism is a clinical and biochemical syndrome characterized by a deficiency in serum androgen levels which may decrease sexual interest, quality of erections and quality of life. Biochemical investigations include testosterone and either bioavailable or calculated free testosterone; prolactin should be considered when hypogonadism has been documented. If clinically indicated, androgen therapy should maintain testosterone within the physiological range avoiding supraphysiologic values. Digital rectal examination and determination of serum prostate specific antigen values are mandatory prior to therapy and regularly thereafter. Androgen therapy is usually long-term requiring regular follow-up, frequent monitoring of blood levels and beneficial and adverse therapeutic responses. CONCLUSIONS: Safe and effective treatments for endocrinologic sexual medicine disorders examined by prospective, placebo-controlled, multi-institutional clinical trials are needed.
