  • Deslorelin is a GnRH agonist. Deslorelin implants can be used as an alternative to dopamine agonists to induce fertil eoestrus in the bitch in anoestrus. The deslorelin implant can be used successfully in the queen for oestrus inhibition. Deslorelin acetate did not significantly affect the spontaneous contraction amplitude but caused a decrease in the frequency in the dorsal and ventral parts of the bladder.
