testosterone reference range for male Scottish Fold

[Jonas0]

Hello friends, I have a 2.5 year old male Scottish Fold who has been diagnosed with congenital adrenal hyperplasia. His vet had until recently refused to neuter him due to consistently high ALT levels. However, in diagnosing his adrenal hyperplasia, his T4 and testosterone levels were tested. While T4 is within normal range, his testosterone levels is showing 5.0 nmol/l (no reference range was provided by the testing Lab). The vet has advised that 5.0 nmol/l is extremely low and complicates his treatment, and that we should move forward with a neutering operation irrespective of ALT levels. I've not been able to find anything online about reference ranges for testosterone levels for male Scottish Folds (or cats in general), and would appreciate advice if any expert reads this. Thank you!

I don’t know if this is what you are looking for or similar test to your cats but found this in a study of testosterone in feral tomcatsl

The range of testosterone concentration was 0–23.5 ng/ml and androstenedione concentration 0–35.7 ng/ml.

Thank you! -- this seems to confirm that my cat's levels are at the very low end... I wonder if anyone has advice on whether this necessitates moving forward with his neutering irrespective of his high ALT levels.

I fail to see how neutering is supposed to heighten low testosterone levels. In your position, I’d ask the vet for more details. If you have reason to doubt their opinion, go consult with a different specialist, in a completely different clinic — just make sure you have all previous testing your cat has previously gone through on hand.
