[1] [2] Advancements in medical technology have enabled women to accurately check their pregnancy status by using 'pee-on-a-stick' pregnancy test kits at home. Before these accessible and ...
The African clawed frog or platanna, Xenopus laevis, was first widely used in laboratories in pregnancy assays in the first half of the 20th century.When human chorionic gonadotropin, a hormone found in substantial quantities in the urine of pregnant women, is injected into a female X. laevis, it induces them to lay eggs.

Clawed frogs are carnivores and will eat both living and dead prey, including fish, tadpoles, crustaceans, annelids, arthropods, and more. Clawed frogs will try to consume anything that is able to fit into their mouths.

A later alternative to the rabbit test, known as the "Hogben test", used the African clawed frog, and yielded results without the need to cut the animal open. [6] Modern pregnancy tests continue to operate on the basis of testing for the presence of the hormone hCG in the blood or urine, but they no longer require the use of a live animal.
