New thread for bbabs021553

Kinyonga, this is isn't directly relevant to the topic at hand but, I've heard it said that if females (in this case, panthers) aren't bred before a certain age -say a couple years- then they shut down their reproductive tract and stop producing eggs, refuse to breed, and essentially become more masculine.

I don't necessarily buy it but I'm curious if you've heard of this as well.
 
I haven't heard of that happening in panther chameleons or veileds. I do know that with veileds I've had females not produce eggs for the first 3 years of thier lives and then be mated and produce good clutches. Its happened with my own. I raised some of the babies (couldn't keep all the eggs that hatched of course!) and they lived good long healthy lives...so it didn't have any apparent negative affects on them not producing.
 
Yea I heard it once and didn't really think it was something that made sense. Seems like another wives tail, I was just curious if you'd heard of it before.
 
Just because I haven't heard of it doesn't mean that its not possible...I just don't think it is for panthers or veileds.

I have heard of things like clown fish changing sex though when necessary.
 
I'd only heard it once and it didn't really seem all that rational. The conversation was about female panthers. That if they didn't breed within a couple years that they essentially went through menopause and dedicated more resources to their growth, thereby being larger and more masculine. Therefore, any female you have must be bred while she is young to prevent this from happening.

From everything I've ever learned about physiology in reptiles, this doesn't particularly make sense. But maybe this is a question for Chris A.
