Suprelorin® is a sustained release biocompatible implant that contains the active ingredient deslorelin (gonadotropin releasing hormone (GnRH) agonist).

• Cylindrical implant - similar size to a microchip
• Presented in a pre-loaded implanter with actuator supplied
• Implant is placed subcutaneously between the shoulder blades – no anaesthetic required
• Deslorelin is released from the implant (proprietary lipid mixture) over a well defined profile

Due to the prolonged release of deslorelin, GnRH receptors within the pituitary gland are desensitised. Consequently the production and release of follicle stimulating hormone (FSH) and luteinising hormone (LH) are impaired. No FSH and LH means no testosterone and this means no sperm (See diagram below).
