Semen quality and interval to sterility in tom cats treated with a 9.4 mg deslorelin implant

Gonadotropin-releasing hormone (GnRH) agonists like deslorelin are being increasingly used in tom cats for their efficacy in controlling reproductive behaviour and fertility. Deslorelin implants have been widely available in Europe since 2008. Little, if anything, is known about the interval between treatment and onset of sterility, as well as semen quality, after treatment in tom cats. The purpose of this study was to investigate semen quality and interval treatment sterility in tom cats treated with a 9.4 mg deslorelin implant.
