Have you ever watched an old movie or television show where the expression “the rabbit died” meant that a woman was pregnant? The “rabbit test” was developed in 1931. The test involved injecting the urine of the woman being tested into a female rabbit and then examining the rabbit’s ovaries a few days later.
A hormone in the urine of a pregnant woman would cause follicles in the rabbit’s ovaries to mature and release the ovum. The injected rabbit had to be surgically opened to examine the ovaries for the structure remaining after ovulation and would die whether the woman was pregnant or not. Today’s pregnancy tests do not require the killing of an animal, and results are determined in a matter of minutes rather than days. However, the same hormone is involved in both tests.
Identify the row that depicts the hormone present in the urine of a pregnant woman, the female reproductive hormone that it mimics in early pregnancy, and the structure in the ovaries of rabbits that confirm pregnancy.
