Medical castration is a non-surgical solution for desexing male dogs. It is a resorbable contraceptive implant administered by your veterinarian. The implant is inserted like a microchip beneath the skin between your dog’s shoulders during a consultation with your veterinarian; there is no need to leave your dog for the day. Medical castration does not need your dog to have a general anesthetic or surgery.

For male dogs, medical desexing (castration) provides the benefits of surgical desexing (castration) without surgery, general anesthesia, or testes removal. The implant is gradually reabsorbed by the body and does not need to be removed. 

Once the implant wears off, the dog’s fertility will gradually return.* If you would like to continue the effect of medical castration then a new implant can be administered at either six or twelve months after the initial implant as recommended by your veterinarian.

_{*Discuss with your veterinarian the expected length of time, especially in breeding dogs.}
