Talk:Bidder's organ

First para
The first paragraph should describe the function in nature of Bidder's organ.
 * 1) Is it a rudimentary ovary with germ cells?
 * 2) If the frog's testes are removed (castrated) do the gonadotropins rise?
 * 3) Does this stimulate Bidder's organ to become a completely normal ovary that makes estrogen and other female hormones?
 * 4) That even makes eggs? Is such a frog now a fertile female?
 * 5) What is the putative function in nature?
 * 6) Can it become functional under any natural circumstances?
 * 7) Some fish can change sex in certain natural circumstances. In some reptiles I think a difference in incubation temperature determines which gonads (male or female) develop? Does a similar phenomenon happen in these frogs?
 * 8) Do all frog species have this? Any other amphibians?

Don't keep us in suspense! Tell us more! Inquiring minds want to know! alteripse 03:10, 20 Jan 2005 (UTC)

Bisexual
The article claims:
 * It therefore becomes a fully sexually functional female, which leads some zoologists to conclude that toads are actually bisexual and paedomorphic

and erroneously links to bisexual, which is was a disambiguation page.

However I can't fix the link because this doesn't seem to fit any of the three meanings of bisexual from Bisexual (disambiguation): bisexuality (sexual orientation), botany (not a plant), or biology (a species which has two different sexes, such as humans).

Perhaps this is hermaphroditism, or something else? I'm not a biologist. Please fix the word and link. I've removed the link in the mean time. OliverL 10:09, 6 January 2006 (UTC)

Correction needed
... the Bidder's organ enlarges and produces viable oocytes, ... It therefore becomes a fully sexually functional female, ... By grammatical rules, the pronoun "It" stands for the Bidder's organ, not the toad that the sentence is intended for. An organ cannot becomes a fully sexually functional female. --Mirrordor 18:59, 29 July 2012 (UTC)

Corrections made
The previous text included a rather fanciful misinterpretation of the sources, claiming that males could grow uteri and oviducts and gain full sexual function as females. The citations state the opposite. The most recent paper I could find that made the full-function claim is from the 1920s (http://www.eje-online.org/content/13/1/24.full.pdf+html), although it was repeated in David O. Norris's Vertebrate Endocrinology in 2007. Corrected these problems and dropped a non sequitur mention of paedomorphosis (not in cited sources, or any I could find). — Preceding unsigned comment added by 216.227.56.30 (talk) 20:43, 18 September 2016 (UTC)
