Making A Pregnancy Test With A Frog!

In the early 1900s, doctors used frogs for pregnancy tests. According to this ancient method, called the” Hogben test”, doctors took the urine of a woman thought to be pregnant and injected it into the hind legs of an African clawed frog. This frog was kept under observation for 12 hours. If the Frog ovulates within 12 hours, this indicates that the woman’s pregnancy hormones switch to the Frog and impregnate the Frog. This proved that the woman whose urine was taken was pregnant.

This method continued in Europe until the 1960s. Modern methods could only be passed after this date.
