Wow, this excerpt from Pain & Prejudice is pretty hard-hitting, especially around the paternalistic tendency treating women as ‘walking wombs’.
In the early 20th century, the endocrine system, which produces hormones, was discovered. To medical minds, this represented another difference between men and women, overtaking the uterus as the primary perpetrator of all women’s ills. Still, medicine persisted with the belief that all other organs and functions would operate the same in men and women, so there was no need to study women. Conversely, researchers said that the menstrual cycle, and varied release of hormones throughout the cycle in rodents, introduced too many variables into a study, therefore females could not be studied.
