Objective: Androgenic-anabolic steroids (AAS) are commonly used by athletes and recreational athletes. In some cases they induce persistent anabolic steroid-induced hypogonadism (ASIH).
Design: In an observational study we assessed the function of the pituitary-gonadal axis in a series of men with suspected ASIH.
Methods: Clomiphene stimulation test (CST) was performed in 13 hypogonadal adult men with previous, prolonged exposure to AAS. We evaluated the response of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and total testosterone (T) to 50 mg of clomiphene daily administered for a week. Mean concentrations of hormones before and after clomiphene administration were respectively (mean ± SD): 3 ± 1.2 and 8.3 ± 2 mIU/ml for LH; 3 ± 1.1 and 10 ± 14.6 mIU/ml for FSH; and 2.3 ± 0.6 and 7.2 ± 1.7 ng/ml for T (p<0.001).
Conclusions: Men with ASIH, after a long-time withdrawal of AAS, present an intact reaction of gonadotropins and testosterone to clomiphene stimulation.
