Virbac Animal Health has announced that its medical castration implant Suprelorin 9.4mg has received a marketing authorisation for use in ferrets.

The neutering of male ferrets (hobs) is recommended to suppress fertility, decrease odour and reduce territorial aggressive behaviour and urinary marking¹. According to Virbac, Suprelorin offers temporary sterilisation but without the need for surgery, and its use prevents the high Luteinizing hormone (LH)/Follicle-stimulating hormone (FSH) levels which occur following surgery and which can play a role in the development of hyperadrenocorticism².

Suprelorin is a slow-release implant containing the gonadotropin-releasing hormone (GnRH) agonist deslorelin. Once injected under the skin of healthy, sexually mature and entire ferrets, the continuous low release of deslorelin from the implant causes an interruption of the HPA circuit, leading to a reduction in LH/ FSH levels and therefore testosterone production. This results in a reduction of libido, spermatogenesis and testicle size.

The implant lasts for up to four years, at which stage the ferret can be re-implanted to maintain the effect.

Chris Geddes MRCVS, Virbac Product Manager, said: "For owners looking for a surgery-free route to the castration of male ferrets and the problems it can cause, Suprelorin provides a simple and effective alternative."

Suprelorin 4.7mg has been available for use in dogs since 2008. Suprelorin 9.4mg was launched in 2011.
