Dusky Gopher Frogs are one of the most endangered frogs in the US, with possibly only around 100 animals surviving in the wild. Around 1,400 tadpoles were produced by Henry Doorly Zoo, using eggs collected from one of their female frogs, and sperm collected from males at Henry Doorly Zoo and from males at Memphis Zoo.
This is the first time that sperm has been collected from frogs at one zoo, transported to a second zoo, and used to successfully produce tadpoles. Hopefully, processes like this one will be used more often to bolster the numbers of endangered amphibians in captivity.

That is exciting news that these zoos were able to work together in order to reproduce their stock.
While it may help these frogs and some others there are still many out in the wild that are in danger.

I think this is so cool, I try to help our local frogs by raising some frogspawn to tadpoles before releasing them each spring. But IVF all the way if it works we need to keep species from extinction.

This is great news to hear that IVF can not only be useful for humans but also the frog world. Wow! I am impressed, I do hope it works
