Sterilization in Alberta, 1928 to 1972: gender matters.

Alberta, Canada, passed a Sexual Sterilization Act in 1928 and up until its repeal in 1972, over 2,800 people were sterilized. Women were overrepresented in the number of sterilizations performed. This paper explores how changing understandings of eugenics led to a subtle transformation which resulted in a "two-pronged" system that targeted mentally defective men, often a danger to society, and mentally normal but morally abnormal women who consented to sterilization. The end result was success for the movement in terms of the types and numbers of people sterilized, and in the longevity of the program.
