Northern Leopard Frog (Rana pipiens)

Semi-differentiated male	Pesticide induced gonadal abnormalities (intersex)
Semi-differentiated male leopard frog stage 42.	Leopard frog stage 42 exposed to Roundup pesticide formulations.

**Please note that we are still trying to define what makes these two gonadal transitions different from eachother.

We are sure that one is a natural transition and that the other was induced by contaminants but in order to define that the gonads are actually intersex we would have to understand what can be considered normal.
