I purchased a 4 year old mare a few months back and was told she has a granulosis tumor on her ovary. She had always acted a bit stallion-like, cycled very hard, acted "bi-polar", and mounted other horses both male and female (but that could have been just her playing). She had been diagnosed a year ago with the tumor due to her inhibin level. I spoke to 2 clinics in NJ, Dr Karlin at Mid Atlantic and Dr Smith at NJ Equine. We finally reached out and spoke to the vets at New Bolton in PA. They mentioned how they don't feel it is definitely a tumor on the ovary. She has had attitude issues since about 8 months of age. They feel there is a good chance she may be a pseudohermaphrodite. I was also told that her inhibin level could be indicative of either or. We won't know for sure what condition she has until I have an ultrasound done on her which will be done the day of surgery. Regardless, she is going in next week to have whatever issue she has resolved via lapro surgery. I'm not very familiar with the pseudohermaphrodite condition. I examined her genitalia and everything is normal. The vet tells me she could still possibly have a testicle in her abdomen. I am trying to grasp the idea of having to geld my mare?
The point of this thread is, I am wondering if there is anyone on here who has experienced either condition with their horses. If so could you explain any changes your horses had temperment-wise post surgery?
