Supra-physiological doses of anabolic androgenic steroids impact erythropoietin and blood parameters.
Drug testing and analysis(2023)
摘要
Hematological parameters and erythropoiesis are known to be influenced by anabolic androgenic steroid (AAS) use. However, little is known in relation to supra-physiological doses of AAS. Therefore, the aim of this study was to evaluate the effect of supra-physiological doses of AAS on serum and urinary erythropoietin (EPO), and blood parameters, from self-reported AAS users. Serum EPO levels were higher in testosterone positive AAS users (11.83 mIU/mL ± 4.19) than non-positive (6.60 mIU/mL ±2.70, p=0.03), while no differences in urinary EPO levels were noted. There were positive correlations between serum EPO and testosterone levels (rs=0.46, p=0.01) and reticulocyte percentage (rs=0.43, p=0.02). Individuals with AAS-induced hypogonadism (ASIH; luteinizing hormone levels <1.4 IU/L) had approximately 75 % higher serum EPO (p<0.05) and 140 % higher high fluorescence reticulocyte fractions (p<0.001), as well as other affected hematological parameters, compared to non-ASIH individuals. The results extend the knowledge of how endocrine and hematological biomarkers are affected by AAS doping.
