Anabolic-androgenic steroids in sport

Introduction and objective Anabolic-androgenic steroids (AAS) are a group of doping substances. They cause muscle hypertrophy and an increase in strength. Moreover, they may lead to dangerous side effects. Knowledge of the side effects of AAS use is necessary because in clinical practice we often encounter patients who decide to supplement with steroids. The aim of the study is to present information on the epidemiology, mechanism of action, methods of detecting AAS, the impact of the substance on the male and female body, and a description of organ side effects, highlighting: the cardiovascular system, the nervous system and the psyche.   Review methods Literature search was conducted in the PubMed database with inclusion criteria ‘free full texts’ and publications date between 2015 – 2024. A total of 7272 results were found; 30 publications were ultimately included in the review.   Abbreviated description of the state of knowledge Overusing AAS is very popular among people training at the gym. They have an anabolic effect on muscle tissue. They contribute to infertility in men and masculinization in women. Stimulation of androgen receptors above physiological doses of AAS leads to vascular changes that, in extreme cases, may lead to sudden cardiac death. Moreover, they accelerate brain aging. An increase in aggression and risky sexual behavior has been observed among people using doping. The diagnostic material used in anti-doping tests is urine and blood serum. Summary AAS abuse is a serious public health problem. Men who want to improve their figure and decide to use doping are particularly at risk. Due to the easy availability of steroids, society should be made aware of the negative effects of steroid use.
