I got a question third hand, (friend > wife > me) and a quick search leaves me wondering where to look for the answer.
The friend has an 11 year old female rabbit that has not been spayed. She wants to know if rabbits experience menopause, and what if any similarities it has with human menopause (transition to a non-reproductive state, with associated symptoms)
A quick glance at Wikipedia teaches us that rabbits are induced ovulators which means they don't have normal cycles, they ovulate in response to sex. So obviously there are going to be some differences from humans. The closest scientific study I find is Efficacy of red clover isoflavones in the menopausal rabbit model. which uses "experimentally induced menopause" to test a drug. So while not really addressing this question does provide for the probability of a rabbit/human similarity.
Do rabbits experience menopause? At what age, and what kind of symptoms? Are they able to reproduce until they die of old age (16+ years old)?
