Cancer
WHO organization International Agency for Research on Cancer (IARC) list AAS under Group 2A: Probably carcinogenic to humans. Cardiovascular
Other side-effects can include alterations in the structure of the heart, such as enlargement and thickening of the left ventricle, which impairs its contraction and relaxation, and therefore reducing ejected blood volume. Possible effects of these alterations in the heart are hypertension, cardiac arrhythmias, congestive heart failure, heart attacks, and sudden cardiac death. These changes are also seen in non-drug-using athletes, but steroid use may accelerate this process. However, both the connection between changes in the structure of the left ventricle and decreased cardiac function, as well as the connection to steroid use have been disputed.AAS use can cause harmful changes in cholesterol levels: Some steroids cause an increase in LDL cholesterol and a decrease in HDL cholesterol. Growth defects
AAS use in adolescents quickens bone maturation and may reduce adult height in high doses. Low doses of AAS such as oxandrolone are used in the treatment of idiopathic short stature, but this may only quicken maturation rather than increasing adult height. Feminization
There are also sex-specific side effects of AAS. Development of breast tissue in males, a condition called gynecomastia (which is usually caused by high levels of circulating estradiol), may arise because of increased conversion of testosterone to estradiol by the enzyme aromatase. Reduced sexual function and temporary infertility can also occur in males.
Acquired idiopathic generalized anhidrosis (AIGA) is characterized by generalized absence of sweating without other autonomic and neurologic dysfunction.AIGA is classified into 3 subgroups: idiopathic pure sudomotor failure (IPSF), sweat gland failure (SGF), and sudomotor neuropathy, with each subgroup presenting a different pathogenesis. Diagnosis
Quantitative sudomotor axon reflex test and microneurography are used in the diagnosis of AIGA. However, these refined methods are mostly used for research purposes and not generally available.Skin biopsy analysis may play a crucial role in the identification of AIGA subgroups. See also
