Suprelorin® will provide temporary sterilisation for at least six months; the implant can be repeated safely to maintain the effect. A twelve month implant is to be launched in the future. Suprelorin® is temporary and therefore can be used in specific situations where permanent desexing is not wanted, for example;

• Allowing temporary desexing before breeding,
• Suppresses specific males over a breeding season,
• Enabling dog owners that so not like the idea of anaesthetic or surgery to desex their dogs.

Trials of up to five consecutive treatments of this product over three years have shown that fertility returns when treatment ends.

Benign prostatic hyperplasia (BPH) is a condition that causes enlargement of the prostate gland. BPH is common in older dogs that have not been desexed. Signs of BPH to look for include:

• Blood in the urine and the ejaculate
• Straining while defaecating
• Constipation
• Discharge from the penis

One way to treat BPH is castration, but this can be problematic with older dogs that are often not good candidates for general anaesthetic. Suprelorin® provides a non-surgical alternative that only needs to be administered every 6 months (12 monthly in future).

Certain behavioural problems are driven by testosterone, namely roaming, inter-dog aggression and certain sexual behaviours. Castration may not solve 100% of cases. Suprelorin® can be used as a ‘road-test’ for that response that would be seen without undergoing permanent surgery. If a favourable response is seen castration can be carried out or Suprelorin® can be continued.
