EFFECTS OF GONADOTROPIN-RELEASING HORMONE ANTAGONIST DEGARELIX ON MUSTH AND SERUM TESTOSTERONE CONCENTRATIONS IN ASIAN ELEPHANTS ( ELEPHAS MAXIMUS).

Two male Asian elephants (bulls 1 and 2) in musth were subcutaneously injected with a long-acting gonadotropin-releasing hormone (GnRH) antagonist, degarelix acetate (240 μg/kg; total dose of 960 mg). Musth behavior (MB) and temporal gland secretions (TGS) were monitored and serum testosterone concentrations were determined. In bull 1, MB and TGS ceased on day 1 and reappeared 5.
