Male toads of the Bufonidae Family have rudimentary ovaries designated Bidder's organs,
and if the testes are removed this organ develops into a functional ovary, representing a
morphological strategy for the reproduction of the species. The Bidder's organ of Bufo
ictericus was examined using routine and histochemical techniques by light microscopy and
transmission electron microscopy. Each Bidder's organ presented a typical ovarian
morphology, being composed of a cortex and a medulla. Bidderian follicles in different …
