Statistical Analysis of the Urine Steroid Profile in Chinese Athletes / 中国运动医学杂志

ABSTRACT

Objective To investigate the steroid levels of urine in Chinese athletes. Methods Subjects were 1217 Chinese athlete, 8 kinds of steroids named androsterone (An), etiocholanolone (Etio), dihydrotestosterone (DHT), dehydroepiandrosterone (DHET), Testosterone (T), Epitestosterone (ET), 5?-androstane-3?, 17?-diol (5?-diol), 5?-androstane-3?, 17?-diol (5?-diol) were measured by gas chromatography combined with mass spectrometry (GC/MS) after the urine sample being treated with chemical pre-extraction, hydrolysis, extraction and derivatization. Results The urine steroid levels of the Chinese male athlete were higher than those of the female athlete, but both male and female athlete had a lower urine steroids especially testosterone and 5?-androstane-3?,17?-diol, 4～7 times lower than other country's athletes. Some ratios of urine steroids such as An/Etio, T/ET, 5?-diol/5?-diol were relatively steady, which were affected less by gender.
