The detection of the misuse of testosterone gel

Publication: Chapter in Book/Report/Conference proceedingConference contribution - Article for conferenceResearch


To develop a method for the detection of the misuse of testosterone gel (T-gel) 18 healthy male volunteers were treated for six weeks continuously and intermittently with T-gel (100 mg testosterone per day). Blood and urine samples were collected before, during and after the application of T-gel. The following results were obtained. The treatment with T-gel leads to an increase of serum testosterone and a decrease of LH. The most discriminating parameters of the steroid profile are the ratios testosterone/epitestosterone, 5α-androstane-3 α,17ß-diol / epitestosterone and androsterone/epitestosterone. Individual reference ranges of the parameters are more suitable for the detection of the misuse of T-gel than population based reference ranges. For the GC/C/IRMS analysis suitable target compounds are testosterone and 5α -androstane-3 α,17ß-diol. Verf.-Referat
