Gender
Gender is the range of characteristics pertaining to, and differentiating between, masculinity and femininity. Depending on the context, these characteristics may include biological sex (i.e., the state of being male, female, or an intersex variation), sex-based social structures (i.e., gender roles), or gender identity. People who do not identify as men or women or with masculine or feminine gender pronouns are often grouped under the umbrella terms non-binary or genderqueer. Some cultures have specific gender roles that are distinct from "man" and "woman," such as the hijras of South Asia. These are often referred to as third genders.
Gender Studies
Gender studies is a field for interdisciplinary study devoted to gender identity and gendered representation as central categories of analysis. This field includes women's studies (concerning women, feminism, gender, and politics), men's studies and queer studies. Sometimes, gender studies is offered together with study of sexuality.
Humanities
Humanities are academic disciplines that study aspects of human society and culture. In the renaissance, the term contrasted with divinity and referred to what is now called classics, the main area of secular study in universities at the time. Today, the humanities are more frequently contrasted with natural, and sometimes social, sciences as well as professional training.
Humanities
Social science and humanities … have a mutual contempt for one another, the former looking down on the latter as unscientific, the latter regarding the former as philistine. … The difference comes down to the fact that social science really wants to be predictive, meaning that man is predictable, while the humanities say that he is not.
Allan Bloom, The Closing of the American Mind (New York: 1988), p. 357

Between a real man and a real woman there are innumerable others, some of which are significantly characterized as belonging to the intermediate sex.

Gender is a huge hot-button issue for lots of people who feel strongly about it, I am not interested in triggering those strong feelings.
