Check with Wayne Hill and Peter Pritchard... I believe they were involved on coming up with such a test with Galapagos tortoises... which failed. I believe they actually went to the islands to collect blood samples. I don't know if it was ever written up but Wayne did give a talk on it way back when.

>>hormone levels for tortoises? If yes is it one test fits all or does each species have to be established as to what is normal per. Can a male become sterile in captivity for any known reason like overheating,toxic consumtion? Is there any blood test for sterility in males. Thanks in advance if you know of any papers on this or people that may know. Vic M
