Chemical Profiles of Male African Elephants, - Oxford Academic

Abstract. This study reports concentrations of testosterone and dihydrotestosterone in both serum and temporal-gland secretions of male African elephants (Loxodonta africana), including ra-diocollared elephants, and identifies a spectrum of volatile components in the temporal-gland secretions.Androgens in the serum (testosterone and dihydrotestosterone) were measured in 111 adult male African ...

This report discusses three areas of investigation: (1) The chemical components in the temporal gland secretion (TGS) of Asian (Elephas maximus) and African (Loxodonta africana) elephants were characterized by radioimmunoassay (RIA) for testosterone (T) and dihydrotestosterone (DHT) levels and by on-column capillary column gas chromatographic analysis of volatiles. An inverse relationship ...
