ASSESSING THE EFFICACY OF DESLORELIN ACETATE IMPLANTS (SUPRELORIN) IN ALTERNATIVE PLACEMENT SITES

Abstract Hormonal contraception is being increasingly used to manage captive animals in zoological collections. Many of the animals placed on contraception are of genetic importance within captive breeding programs; therefore, it is imperative that the application of contraceptive products minimize potential side effects and facilitate a return to fertility if required. Deslorelin acetate implants (Suprelorin®) are one example of a hormonal contraceptive that is frequently used in captivity as they are easy to use and effective in most species. It is hypothesized that removing implants may hasten reversal of contraception treatment; therefore, placement in a location where they can easily be recovered is advocated. In this report, the efficacy and safety of Suprelorin implants placed in their recommended site between the scapulae is compared with alternative placement sites where implants can more easily be located for removal.
