Frogs as Pregnancy Tests.

General
1

In the early 20th century, a surprising method was used to test for pregnancy: doctors would inject a woman’s urine beneath the skin of a female African clawed frog (Xenopus laevis). If the woman was pregnant, the frog would lay eggs overnight.

Why did this work? The urine of pregnant women contains the hormone human chorionic gonadotropin (hCG), produced by the placenta shortly after implantation. This hormone stimulates the frog’s ovaries, causing her to release eggs.

This unusual but accurate method was developed in the 1920s by English biologist Lancelot Hogben during his time in South Africa. It proved so reliable that many hospitals kept frog colonies for pregnancy testing right up until the 1960s.

This is just a new information, inducing HCG hormone from pregnant women into frogs, is such a unique way but absolutely backed by science method to detect pregnancy

Sometimes I wonder how do they discover these methods like so unusual but still work like magic and accurate too.

It’s a fascinating reminder of how biology and innovation intersect, turning a humble amphibian into a living diagnostic tool.

Crazy thing but some one had the knack to think through the scientific logic and try it.

The wheels of science mill grind slowly but they do surely.
