When do frogs fertilize eggs?

Frogs fertilize their eggs externally, meaning it happens outside the female's body.

Here's the process:

1. Male and female frogs come together. The male often clasps the female in a process called amplexus.

2. The female releases her eggs into the water.

3. The male releases sperm over the eggs. This is the fertilization process.

So, fertilization happens immediately after the female releases her eggs.
