Abstract

A unique rudimentary ovarian structure known as the Bidder's organ (BO) occurs at the anterior end of the gonads of male bufonids. I examined BO volume in reproductively active (RA) versus nonreproductively active (NRA) males of Bufo woodhousii to examine changes in BO volume in relation to reproductive status. BO volume was larger in NRA males, suggesting that cues associated with sexual maturity influence BO volume.
