Everything You Didn't Know About Frog Pregnancy Tests

This video discusses the history of frog pregnancy tests and chytrid fungus. Before at-home pregnancy tests existed, people used frogs to determine if they were pregnant. The use of frog pregnancy tests had incredibly terrible consequences for amphibians around the world. When these frogs were eventually released from their labs, they spread a deadly fungus, called "chytrid fungus" or Batrachochytrium dendrobatidis, across every continent. This caused amphibian populations to plummet across the world and many amphibians went extinct entirely. In telling this story, this video answers the following questions:

My Grandma used to be a nurse, and told me about using frogs for pregnancy tests. Pretty strange procedure.

Here I am, a herpetologist, screaming “THE CHYTRID FUNGUS” at my screen at 6:16

Can I get my medal now? because I’m in massive college debt and I need something to show for it.

“What are you doing?”
“injecting pee into a frog”

So in other words, the frog extinction wouldn’t happened if us human either 1: import them back to their homeland and release them or 2: Put them down since they’re considered invasive species to the other lands.
