The aim of the present study was to identify relevant fecal testosterone metabolites in the Eurasian lynx ( Lynx lynx) using HPLC analysis and to evaluate the specificity of two testosterone immunoassays against these fecal metabolites. Finally, fecal hormone analysis was used to characterize season...
