View clinical trials related to Androgen Deficiency.
Filter by:This study relates to men with hypogonadism, a condition describing a deficiency of androgens such as testosterone. Deficiency of these hormones occurs in men due to testicular (primary) or hypothalamic-pituitary (secondary) problems or may be observed in men undergoing androgen deprivation therapy for prostate cancer. Testosterone plays an important role in male sexual development and health, but also plays a key role in metabolism and energy balance. Men with testosterone deficiency have higher rates of metabolic dysfunction. This results in conditions such as obesity, nonalcoholic fatty liver disease, diabetes, and cardiovascular disease. Studies have confirmed that treating testosterone deficiency with testosterone can reduce the risk of some of these adverse metabolic outcomes, however cardiovascular mortality remains higher than the general population. We know that testosterone deficiency therefore causes metabolic dysfunction. However, research to date has not established the precise mechanisms behind this. In men with hypogonadism there is a loss of skeletal muscle bulk and function. Skeletal muscle is the site of many critical metabolic pathways; therefore it is likely that testosterone deficiency particularly impacts metabolic function at this site. Men with testosterone deficiency also have excess fat tissue, this can result in increased conversion of circulating hormones to a type of hormone which further suppresses production of testosterone. The mechanism of metabolic dysfunction in men with hypogonadism is therefore multifactorial. The purpose of this study is to dissect the complex mechanisms linking obesity, androgens and metabolic function in men. Firstly, we will carry out a series of detailed metabolic studies in men with testosterone deficiency, compared to healthy age- and BMI-matched men. Secondly, we will perform repeat metabolic assessment of hypogonadal men 6 months after replacement of testosterone in order to understand the impact of androgen replacement on metabolism. Lastly, we will perform the same detailed metabolic assessment in men with prostate cancer before and after introduction of a drug which causes testosterone deficiency for therapeutic purposes.
Overarching aim of project Performance and image enhancing drugs (PIEDs) are pharmacological agents acquired illicitly to improve physical strength and endurance as well as to obtain a leaner and more muscular appearance. Androgenic anabolic steroids (AAS) are the most frequently used PIED and include testosterone and its synthetic derivatives. However, PIEDs also include other hormones, e.g. growth hormone (GH), insulin-like growth factor I (IGF-I), glucocorticoids, insulin and thyroxin. Originally, the use of PIEDs was predominately restricted to elite athletes. However, today most users of PIEDs are recreational athletes. In USA, the prevalence of recreational PIED users (three million) exceeds the prevalence of type 1 diabetes. This appears to be the same in Denmark, where the estimated prevalence of recreational users of PIEDs is 44,000, compared to approximately 30,000 patients with type 1 diabetes. The access to AAS is easy due to the unregulated and illicit sale on the internet. Furthermore, PIED use is common in the young population with possible detrimental effects on future health and well-being. PIEDs are linked to premature death and a wide spectrum of somatic and psychological disorders. However, clinical data on the use of PIEDs is currently limited. Randomized trials of PIEDs are unethical as this would require administration of potentially harmful supra-physiological doses of hormones and this is the rationale behind our proposal to perform an observational study. With this project the investigators propose to a) Perform a cross-sectional nationwide study of current and former users of PIEDs (N=1200), focusing on AAS. In particular, the investigators will pay attention to: 1. Preclinical cardiovascular disease 2. Psychological well-being, aggression and quality of life 3. Biomarkers of ageing 4. Body composition and muscle strength b) Establish a nationwide biobank containing blood, urine and hair samples from current and former users of PIEDs.
This study is being done to establish the mechanisms underlying insulin resistance (reduced insulin action that can lead to high blood sugar and maybe diabetes) in patients undergoing androgen deprivation therapy (ADT) for prostate carcinoma as well as to investigate the role of pioglitazone therapy in reduction/ reversal of that insulin resistance
The aim of this trial is to evaluate whether testosterone replacement results in greater improvement in pain perception, pain tolerance, sexual function, physical function and quality of life when compared with placebo in women with chronic back pain treated with opioids who have low testosterone.
This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.
The COVID-19 Androgen Sensitivity Test is a non-invasive In-Vitro Diagnostic device that utilizes Next Generation Sequencing Technology (NGS). The results of the test are used by a physician to assess the risk of developing severe symptoms following COVID-19 infection, The COVID-19 Androgen Sensitivity Test requires a health care professional to collect a DNA sample using an FDA cleared DNA sample collection kit.
The aim of this study is to analyze the impact of physical exercise through a protocol of concurrent training in the psychological, physical, hormonal and sexual aspects in middle aged men with androgen deficiency in the aging male (ADAM). The study design with randomized clinical trial, comprising men in middle age (40 to 59 years) with ADAM, should be divided into two groups: 1) Control group (CG); 2) Experimental group (EG). Information related to sociodemographic and clinical profile will be collected; Psychological aspects (depressive and anxiety symptoms - Hospital Anxiety and Depression Scale ; stress - Perceived Stress Scale); Physical acpects (IMC; Percentage of body fat; Abdominal obesity - waist circumference in cm; Muscle strength - Biodex System 4 PRO isokinetic dynamometer; cardiorespiratory Fitness - Cycle-ergometer - CASE ECG Stress Testing System, General Electric Medical Systems, Milwaukee, WI); Hormonal aspects (total and free testosterone - blood collection); Sexual Aspect (Sexual satisfaction- International Index of Erectile Function); DAEM (scale of symptoms of aging). Apply a physical exercise protocol using the functional training method over a six-month period. All information will be collected before and after the intervention period. For statistical analysis, use the SPSS statistical package, version 20.0. (Kolmogorov-Smirnov or Shapiro-Wilk test) for the selection of statistical tests.
The purpose of this research study is to understand the effects of testosterone and estrogen on the body's response to the hormone insulin.
The purpose of this study is to find out if androgen deficiency (low levels of testosterone, a male hormone produced by the sex glands) and erectile dysfunction (sexual dysfunction) will predict over time the development of a heart attack, stroke, or death in men with Diabetes Mellitus who have angiographically proven coronary artery disease (CAD) (≥50%) with or without percutaneous coronary intervention (PCI). A substudy aims to show the different factors and processes that may show a relationship between sexual function and levels of androgen in the body to heart disease.
The primary objective of the Registry of HYpogonadism in MEn (RHYME) is to establish and maintain a large, multi-national prospective registry of male patients who have been diagnosed with male hypogonadism (HG), also known as androgen deficiency or testosterone deficiency.
