The rabbit test was an early pregnancy test developed in 1927 by Bernhard Zondek and Selmar Aschheim. The test consisted of injecting the tested woman’s urine into a female rabbit, then examining the rabbit’s ovaries a few days later, which would change in response to a hormone only secreted by pregnant women. Modern pregnancy tests use the same principle but no longer require an animal to discover the presence of the pregnancy hormone.
