How did killing a rabbit in the pre-70s actually determine a woman was pregnant?

The way it worked was - a woman's urine was injected into a female rabbit and then a couple days later the animal was killed and its ovaries examined. Hormones present in a pregnant woman's urine would make the rabbit's ovaries enlarge.


Thankfully, modern chemistry has replaced this 'animal assay' test.How did killing a rabbit in the pre-70s actually determine a woman was pregnant?

How did killing a rabbit in the pre-70s actually determine a woman was pregnant?
I am so glad I was pregnant in the 80's and 90's, I couldn't bear the thought of killing the 4 that would have died from actual pregnancies and the numerous other false alarms I had until I had that wonderful thing called tubal ligation.
I believe it was because the rabbit's ovaries were used to make pregnancy tests for humans.
Otter is close. What they looked for was a corpus luteum cyst of pregnancy in the bunny.
they used the rabbit ovaries for the test,


all those poor bunnies that died
I was born in the 70's so I've not had this experience like you have, grandpa! LMAO!
