Bidders organ

from Wikipedia, the free encyclopedia

As the Biddersche organ or Bidder organ is a will rudimentary ovary in the males of toads ( amphibians referred family bufonidae). This characteristic is considered an anatomical characteristic for the taxonomic delimitation of the family from other frogs . Experimentally, it has been shown that after removal of the inner testes, the Bidders' organ develops into a functional ovary (ovary).

The organ was named after the German physician Friedrich Heinrich Bidder (1810-1894).
