Spaying & Neutering Our Pets
Spaying and neutering are surgical sterilisation procedures performed by a veterinary surgeon.
- Spaying (female animals):
This involves surgical removal of the ovaries and the uterus. It renders the animal unable to become pregnant. - Neutering (male animals):
In males this usually means removal of both testicles (castration), which stops sperm production and greatly reduces testosterone levels.
The procedures are performed under a full general anaesthesia and are considered routine veterinary surgery. Recovery is typically quick with appropriate pain management and post-operative care. A full recovery is expected within about 10-14 days for both males and females
Benefits of Neutering / Spaying
Neutering and spaying provide both health and behaviour advantages, including:
Prevention of unwanted litters — helping manage pet populations.
Reduced risk of reproductive cancers:
– Eliminates testicular cancer risk in males.
– Reduces uterine and ovarian cancer in females.
Behavioural improvements:
– Reduced urine marking and roaming in male cats and dogs.
– Decreased sexual behaviours that can lead to fights or escape attempts.
Health and welfare:
– May reduce risk of pyometra (life-threatening uterine infection) in females.
– Can help reduce hormone-driven aggression.
Every patient is different and the timing of surgery should be determined in discussion with your vet.
Suprelorin — Chemical (Medical) Neutering Option
What is Suprelorin?
Suprelorin® is a slow-release hormonal implant containing deslorelin acetate, a synthetic analogue of Gonadotropin-Releasing Hormone (GnRH). When placed under the skin by a veterinarian, Suprelorin suppresses the reproductive hormone axis to temporarily reduce fertility and testosterone-driven behaviours.
It does not require surgical removal in normal use — the implant gradually releases medication and bio-degrades over time.
How It Works
- Deslorelin initially stimulates, then suppresses the pituitary hormones (LH & FSH).
- This leads to reduced testosterone production and decreased sperm production.
- Behavioural signs such as roaming, mounting, and marking are typically reduced.
Because suppression occurs through hormonal control rather than removal of organs, fertility and hormonal function will return when the implant’s effect wears off.
Uses of Suprelorin
Suprelorin has veterinary licensing for:
Male Dogs
- Temporary infertility: testosterone and sperm production are suppressed.
- Commonly used as a reversible alternative to surgical castration.
- Two dose strengths are available:
– 4.7 mg for about 6 months of effect.
– 9.4 mg for about 12 months of effect.
Benefits of Suprelorin
- Offers a reversible alternative to permanent surgical neutering.
- Useful for owners wanting to trial neutering effects before surgery.
- Can be selected for animals where surgery is riskier.
