Will frogs exposed to the hormone estrogen lay more eggs?

Yes

Explanation:

A female frog is able to lay eggs only when the level of estrogen is at the highest level in the body. However both male and female release sperm and egg simultaneously at the same time in order to induce high mating probability. Both male and female acquire a mating posture known as as amplexus which enhances the level of estrogen in females and they thus release their egg .
