The Strangest Pregnancy Test Ever Invented

In the 1930s, science took a strange turn. Doctors discovered that a woman’s pregnancy could be tested — not in a lab, but with a frog. It sounds absurd, but this bizarre method became the first reliable pregnancy test in history. Around the world, scientists collected live frogs, injected them with urine samples, and waited overnight. If the frog laid eggs, the result was positive.

For years, hospitals ran “frog labs,” testing thousands of pregnancies this way — until modern kits replaced them. Yet behind the weirdness lies a forgotten revolution — one that changed medicine, biology, and women’s healthcare forever.

This is the story of how a tiny amphibian shaped modern science — the weirdest pregnancy test in history.
