This is directed to anyone who knows anything about ferret biology. I was just wondering if anyone had tried a semi-castration procedure on a male ferret or if it might have been done as part of a study. What I mean by semi-castration is removal of 1 testicle only. I would think that this would cause a decrease in the level of testosterone during the fertile period (less stinky!) and would cause less agressive and territorial behavior year-round. That is, unless the LH level causes the single testicle to work overtime producing enough testosterone to make up for the missing testicle. I would think having the single testicle would also enable a kit to grow to full size, or close to it, as well as causing his coat to be fuller. I guess it could also sterilize him if it caused enough of a decrease in testosterone production. That would be bad or good depending on if you wanted a breeder. Or you may get the sexual behavior without fertility, which might be like a vasectomized male. I'm not a doctor or a vet so my question might seem a little stupid, but if no one has thought of this or proved it harmful then perhaps some of the vets on the list might look into it. If you're a vet (or not) and know why its a bad idea, please email me. I'm not planning on trying to have this done because my little boy is already neutered, so don't worry about that either. ;) I'm just curious. Thanks. - William [Posted in FML issue 1835]
