Uterine disease in does: what a study of 116 female rabbits reveals
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Does a doe that will never breed really need to be spayed? A study by Mäkitaipale and colleagues, published in 2022 in the Journal of Exotic Pet Medicine, examined the uterus of 116 domestic does — some operated on with no suspected disorder, others showing suggestive clinical signs — and compared the lesions found by age and by the reason for surgery (see the study). Our everyday health guides are gathered in the rabbit care and grooming section.

Frequent lesions, even without visible symptoms
Among the 94 does operated on with no uterine disorder suspected beforehand, 44% still showed a histological abnormality, and 13% carried an actual neoplasm, most often cystic endometrial hyperplasia or adenocarcinoma. In other words, the absence of a clinical sign is no guarantee of a healthy uterus: the disease often progresses silently before showing up as reduced appetite, blood in the urine, or an abdominal mass.
A risk that climbs sharply with age
In does over three years old, malignant uterine tumours affected 40% of the animals studied, with roughly a 19-fold higher risk than in younger does. This echoes older data on uterine adenocarcinoma in does, one of the most common tumours in this unspayed species, and explains why exotics-experienced vets generally recommend preventive spaying before two or three years of age rather than mere monitoring.
What this means for a pet doe
For a doe that will never be bred, spaying is therefore not just a matter of convenience or managing urine marking: it's a preventive measure whose benefit grows with the animal's age. Our article on mistakes to avoid before spaying or neutering covers choosing the right timing and practitioner, and our guide to the exotics vet budget helps you plan for the cost of the procedure.
- 44% of does operated on with no suspected disorder already had a uterine abnormality on histology.
- 13% carried a neoplasm, often found with no prior clinical sign.
- 40% of does over three years old had a malignant uterine tumour.
- 19×: the risk of a malignant tumour in does over three compared with younger does.
These figures aren't meant to needlessly worry owners of an older doe already spayed: they mainly point to the value of planning ahead for spaying rather than waiting for symptoms to appear, at an age when anaesthetic risk also rises.
Frequently asked questions
Can a doe with no symptoms still have uterine disease?
Yes: the study shows nearly half of does operated on with no suspected disorder already had a uterine abnormality on analysis.
At what age does the risk really start climbing?
The risk of a malignant tumour rises sharply after three years, which argues for preventive spaying before that age rather than monitoring alone.
Does spaying remove every health risk for a doe?
It removes the organ in question and so most of the uterine tumour risk, but it remains surgery to discuss with a vet experienced in exotics, especially for an older doe.
