title: Free and bound testosterone in male heroin addicts.
abstract: The plasma levels of the active (free) fraction of testosterone (Te) and of Te Binding Globulin (TeBG) in a group of 42 heroin addicts with similar sexual difficulties were investigated for almost 2 years. Plasma levels of free Te were significantly low and TeBG were significantly high not only in the addicts with low total Te concentrations, but also in the addicts with normal values of total Te.
