Crazy Bulk Review – Detailed and HonestEndogenous testosterone levels have been linked to aggressive behaviour in both animals and humans. Studies administering moderate doses of exogenous testosterone for contraceptive and clinical gevlogen reveal essentially no adverse effects on male sexual and aggressive behaviour. However, investigations and case reports of athletes, usually involving higher doses, demonstrate an association between anabolic-androgenic steroid use and affective and anwbole anabole steroide gevolgen and psychological dependence. Efforts to study the psychological and behavioural effects of anabolic-androgenic steroids are complicated by a variety of methodological limitations. Only 3 prospective, anabole steroide gevolgen studies demonstrating aggression or adverse overt behaviour resulting from anabolic-androgenic steroid use have been reported. With estimates of over 1 million past or current users in the US, an extremely small percentage of individuals using anabolic-androgenic steroids appear to experience mental disturbances severe enough to anabole steroide gevolgen in clinical treatment and medical case reports. Even among those so affected, the roles of previous psychiatric history, genetic anabloe to addictions or mental disorders, environmental and peer influences, and what is dianabol cycle expectations remain unclear.

Anabolic androgenic steroids AASs are appearance and performance-enhancing drugs APEDs used in competitive athletics, in recreational sports, and by body-builders. The global lifetime prevalence of AASs abuse is 6. Many AASs, often obtained from the internet and dubious sources, have not undergone proper testing and are consumed at extremely high doses and in irrational combinations, also along with other drugs. Controlled clinical trials investigating undesired side effects are lacking because ethical restrictions prevent exposing volunteers to potentially toxic regimens, obscuring a causal relationship between AASs abuse and possible sequelae.
Because of the negative feedback in the regulation of the hypothalamic-pituitary-gonadal axis, in men AASs cause reversible suppression of spermatogenesis, testicular atrophy, infertility, and erectile dysfunction anabolic steroid-induced hypogonadism. Should spermatogenesis not recover after AASs abuse, a pre-existing fertility disorder may have resurfaced. AASs frequently cause gynecomastia and acne. In women, AASs may disrupt ovarian function.
Chronic strenuous physical activity leads to menstrual irregularities and, in severe cases, to the female athlete triad low energy intake, menstrual disorders and low bone mass , making it difficult to disentangle the effects of sports and AASs. Acne, hirsutism and irreversible deepening of the voice are further consequences of AASs misuse.
There is no evidence that AASs cause breast carcinoma. National Center for Biotechnology Information , U. Didn't get the message? Add to My Bibliography.
