wow. I can't believe it, usually you can dredge up more than an encyclopedia.

Sorry. It turns out that I am human after all. I know, I know, I am just as disappointed as you at this revelation.

I've heard of male frogs laying eggs when treated with hormones over an extended period of time. Many pollutants are either estrogens or pseudo estrogens, which means they can make wild amphibian males develop female characteristics. There was an extreme case of this shown by Tyrone Hayes on that PBS documentary a few months ago - a male Xenopus had reacted to a pollutant so strongly that it behaved as a female and laid eggs.

I don't know anything specific about it, but I have heard of it happening as wel, esp in african frogsl. There are some fish that change sexes as well. My opinion is that other than pollutants it is nature's way of ensuring procreation. God made some crazy critters Another wonder.
