Hello all; Well, I just returned from the vet's office after watching Dr. Dyer perform Sunny's exploratory surgery (which is exactly what it turned out to be, exploratory). He found no evidence of any testicular tissue remaining (Sorry Marshall Farms), and after a very close and extensive look at both adrenals he is positive that it's not adrenal disease. HOORAY!!! So, his opinion is that some other gland is producing testosterone and that is the reason for Sunny's condition. When I left the vet's office this morning, Sunny was wide awake but not moving around much, I guess it "HURTS". He made it through just fine and guess what, so did I. I didn't embarass myself by turning into a puddle on the floor in a dead faint. OK. Now for the question....any vets that may still be with us please, do any of you know what treatment can be started to help Sunny get through his bout of 'spring fever'? Dr. Dyer is going to start him on low levels of estrogen to try to combat the production of testosterone. If any of you don't agree with this course of treatment or can think of anything else to try, please post to the FML or, better yet, e-mail me directly. Thanks in advance for any advice you may share with me. Apryl (and the 'Octa-gang') [Posted in FML issue 2287]
