Talk:Bidder's organ
From Wikipedia, the free encyclopedia

This article is a former featured article candidate. Please view its sub-page to see why the nomination failed. For older candidates, please check the archive. |
The first paragraph should describe the function in nature of Bidder's organ.
- Is it a rudimentary ovary with germ cells?
- If the frog's testes are removed (castrated) do the gonadotropins rise?
- Does this stimulate Bidder's organ to become a completely normal ovary that makes estrogen and other female hormones?
- That even makes eggs? Is such a frog now a fertile female?
- What is the putative function in nature?
- Can it become functional under any natural circumstances?
- 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?
- 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)
[edit] 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)
