Gender studies were born in the United States in the 1950s with research relating to gender and sexual differences from different points of view (biological, psychological, historical, cultural, social, economic, philosophical, political, etc.).

In fact, people who do not fully correspond to gender stereotypes are often negatively connoted, stigmatized.
