does exercise training influence the symptoms of male hypogonadism?
INTRODUCTION: Worldwide many aging males practice sports. A high prevalence of late-onset male hypogonadism has been observed in general population. Sport-participation influences the neuroendocrine system and may decrease serum testosterone. AIM: This preliminary study was designed to estimate the prevalence and the symptoms of undiagnosed testosterone deficiency in aging athletes. METHODS: This observational survey was performed in 183 caucasian male athletes >50 years, in the setting of pre-participation screening. Pituitary-gonadal hormones and symptoms of hypogonadism were investigated. Serum total testosterone (TT), sex hormone binding globulin, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), free-T4, and thyroid stimulation hormone (TSH) were assayed, and free T, bioactive T, and the LH/TT ratio were calculated. The International Index of Erectile Dysfunction (IIEF-15) and the Center for Epidemiological Studies Depression Scale (CES-D) were adminis
