Clitoromegaly is an important sign of virilisation and poses difficulty in sex determination, when present since birth. The diagnosis and treatment in an adult is a major challenge to the treating gynaecologist. The primary reason for its development is androgen excess due to congenital adrenal hyperplasia, polycystic ovarian syndrome, ovarian virilising tumours, neurofibromas, adrenal neoplasm and prolonged intake of anabolic steroids. A case of young nulliparous married woman who presented with primary amenorrhoea and clitoromegaly and was managed successfully has been reported...

Testosterone is an anabolic androgenic steroid hormone involved in brain development, reproduction, and social behavior. Several studies have shown that testosterone can cause impulsivity in humans, which in turn, is linked with mood-related psychiatric disorders and higher risk of death by suicide. The mechanisms by which testosterone abuse influences impulsivity are unclear. The present study aims to understand how testosterone influences impulsivity in a rodent model both at behavioral and molecular levels...

Performance enhancing substances are becoming increasingly popular amongst bodybuilders and people who want to enhance their physiques. However, due to the rise of the Internet and laws prohibiting sales of these substances without prescription, the route of procurement and administration practices have become more and more dangerous. Prior to the mid-1970's, anabolic steroids were not regulated and easily available from physicians and pharmacies in several countries. In 1990, the United States enacted the Anabolic Steroid Control Act, leading to the proliferation of black markets and underground laboratories...

Abuse of substances or methods to enhance the performance is becoming very common in the sports, which often destroys the spirit of competition. The regulatory bodies for sports have reported rates ranging from 5% to 31% for the use of performance-enhancing substances among athletes. Athletes can have serious injuries and morbidities, leading to poor health with the use of such substances. Commonly abused agents in sports include anabolic-androgenic steroids and its analogs, blood, erythropoietin, growth hormone and its derivatives, nutritional supplements, creatine, amphetamines, beta-hydroxy-beta-methylbutyrate (HMB), stimulants, and analgesics...

The biosynthesis of endogenous androgenic anabolic steroids (EAAS) in males varies with age. Knowledge of the general urinary EAAS profile's dependence from aging - not reported up to now - may represents a prerequisite for its exploitation in the screening and diagnostic support for several pathologies. Extended urinary EAAS profiles were obtained from healthy and pathological individuals, using a GC-MS method which was fully validated by a stepwise, analyst-independent scheme. Seventeen EAAS and five of their concentration ratios were determined and investigated using multivariate statistical methods...

RATIONALE: The Worla Anti-doping Agency (WADA) encourages drug-testing laboratories to develop screening methods that can detect as many doping substances as possible in urine. The use of full-scan high-resolution acquisition (FS/HR) with GC/MS for the detection of known and unknown trimethylsilyl (TMS) derivatives of anabolic-androgenic steroids (AAS) provides anti-doping testing bodies with a new analytical tool. METHODS: The AAS were extracted from urine samples by generic liquid-liquid extraction, after enzymatic hydrolysis, and TMS derivatization...

Herein we report a case of a 26-year-old gentleman with severe cardiomyopathy likely secondary to anabolic-androgenic steroid (AAS) abuse who received a HeartMate II (Abbott Laboratories, Abbott Park, IL) left ventricular assist device (LVAD) for rapidly deteriorating heart failure with hemodynamic compromise. Following 18 months on LVAD support, excellent recovery of ventricular function was achieved to allow for LVAD discontinuation. Given that active substance abuse is a contraindication to heart transplantation, few options remain for patients with AAS induced heart failure...

The importance of the present study comes from the lack of sufficient information about the reversibility of the histopathological alterations which may result from anabolic androgenic drugs abuse after some times of stop treatment, as it is one of the prior studies which explored the negative effects of Deca-Durabolin abuse in particular on the hearts, kidneys and testis structures. For this aim, study was performed on 40 male adult mices. Animals were divided into five groups of 8 animals each as follows: treated by Deca-Durabolin (nandrolone decanoate) at 30 g/kg of BW, weekly during one month (GI); two months (GII); three months (GIII); three months followed by six weeks of treatment discontinuation (GIV) and Control (C)...

Several studies have highlighted that nutritional supplements may contain undeclared anabolic steroids that are banned by the International Olympic Committee/World Anti-Doping Agency. Any kind of abuse with these drugs is extremely dangerous because of their side effects. Thus, the control of food additives in order to protect the best consumer health and to limit fraudulent practices in the field of sports is essential. This paper describes a simple and effective qualitative gas chromatography-mass spectrometry (GC-MS) method to detect anabolic androgenic steroids (AAS): androsterone, nandrolene, dehydroepiandrosterone, 5ɑ-androstane-3β, 17β-diol, dihydrotestosterone, testosterone, methenolone acetate, methandienone, boldenone and fluoxymesterone, in food supplements...

The effect of anabolic androgenic steroids on the cardiovascular system is poorly understood. Increased production of free radicals is coupled to the pathophysiology of many alterations within the circulatory system. The only function of the enzyme family NADPH oxidases (NOXs) is the generation of reactive oxygen species (ROS). Therefore, this study investigated the beneficial role of grape seed proanthocyanidin extract (GSPE) in ameliorating cardiac toxicity induced by the anabolic steroid Boldenone in male rats through NOX inhibition and reduction in the expression of NOX2 and NOX4...

Hypogonadotropic hypogonadism is a rare congenital disorder characterised by the deficiency and the absence of puberty and infertility. It is caused by the deficient production, secretion or action of gonadotropin-releasing hormone, which is the master hormone regulating the reproductive axis. Gonadotropin-releasing hormone or gonadotropin injections and testosterone replacement therapy are required in the treatment of this disorder. Psychiatric symptoms and disorders may be seen with the use of anabolic androgenic steroids...

Background Testosterone, nandrolone, and stanozolol are among the highly consumed anabolic androgenic steroids (AASs). Although the desired effects of AAS are being achieved by the abusers, unfortunately, this leads to numerous physical and physiological side effects. The present study was designed to investigate and determine whether early pubertal exposure to AAS treatment had detrimental effects on blood testosterone and estradiol concentrations, mating behavior, and pregnancy outcome during the pubertal period in male rats...

Nandrolone decanoate is an anabolic-androgenic steroid that is frequently used at a very high dose to improve the physical performance. Recently, this drug has been abused by athletes to augment their muscle mass and improve their physical performance. However, this could have an impact on other body systems with the potential increase in its harmful effect. Therefore, the aim of this study was to evaluate the effect of administering a supraphysiological dose of nandrolone decanoate on the hepatic functions and structure of the adult rat and to test the potential reversibility after nandrolone withdrawal...

One of the suspected deleterious effects of androgenic-anabolic steroids (AAS) is the increased risk for tendon rupture. However, investigations to date have produced inconsistent results and it is still unclear how AAS influence tendons. A systematic review of the literature was conducted to identify studies that have investigated the mechanical, structural, or biologic effects that AAS have on tendons. In total, 18 highly heterogeneous studies were identified. Small animal studies made up the vast majority of published research, and contradictory results were reported frequently...
