Gender includes the social, psychological, cultural and behavioral aspects of being a man, woman, or other gender identity. Depending on the context, this may include sex-based social structures and gender expression. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other ; those who are outside these groups may fall under the umbrella term non-binary. A number of societies have specific genders besides "man" and "woman," such as the hijras of South Asia; these are often referred to as third genders. Most scholars agree that gender is a central characteristic for social organization.

Sex assignment is the discernment of an infant's sex, usually at birth. Based on an inspection of the baby's external genitalia by a relative, midwife, nurse, or physician, sex is assigned without ambiguity in 99.95% of births. In the remaining cases, additional diagnostic steps are required and sex assignment is deferred. Sex also may be determined prior to birth through prenatal sex discernment.
Feminist sexology is an offshoot of traditional studies of sexology that focuses on the intersectionality of sex and gender in relation to the sexual lives of women. Sexology has a basis in psychoanalysis, specifically Freudian theory, which played a big role in early sexology. This reactionary field of feminist sexology seeks to be inclusive of experiences of sexuality and break down the problematic ideas that have been expressed by sexology in the past. Feminist sexology shares many principles with the overarching field of sexology; in particular, it does not try to prescribe a certain path or "normality" for women's sexuality, but only observe and note the different and varied ways in which women express their sexuality. It is a young field, but one that is growing rapidly.

Intersex people are individuals born with any of several sex characteristics including chromosome patterns, gonads, or genitals that, according to the Office of the United Nations High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies".
Gender systems are the social structures that establish the number of genders and their associated gender roles in every society. A gender role is "everything that a person says and does to indicate to others or to the self the degree that one is either male, female, or androgynous. This includes but is not limited to sexual and erotic arousal and response." Gender identity is one's own personal experience with gender role and the persistence of one's individuality as male, female, or androgynous, especially in self-awareness and behavior. A gender binary is one example of a gender system.

Feminist biology is an approach to biology that is concerned with the influence of gender values, the removal of gender bias, and the understanding of the overall role of social values in biological research and practices. Feminist biology was founded by, among others, Ruth Bleier of the University of Wisconsin-Madison. It aims to enhance biology by incorporating feminist critique in matters varying from the mechanisms of cell biology and sex selection to the assessment of the meaning of words such as "gender" and "sex". Overall, the field is broadly defined and pertains itself to philosophies behind both biological and feminist practice. These considerations make feminist biology debatable and conflictive with itself, particularly when concerning matters of biological determinism, whereby descriptive sex terms of male and female are intrinsically confining, or extreme postmodernism, whereby the body is viewed more as a social construct. Despite opinions ranging from determinist to postmodernist, however, biologists, feminists, and feminist biologists of varying labels alike have made claims to the utility of applying feminist ideology to biological practice and procedure.
The Phall-O-meter is a satirical measure that critiques medical standards for normal male and female phalluses. The tool was developed by Kiira Triea based on a concept by Suzanne Kessler and is used to demonstrate concerns with the medical treatment of intersex bodies.
Intersex, in humans and other animals, describes variations in sex characteristics including chromosomes, gonads, sex hormones, or genitals that, according to the UN Office of the High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies". Intersex people were historically termed hermaphrodites, "congenital eunuchs", or even congenitally "frigid". Such terms have fallen out of favor, now considered to be misleading and stigmatizing.
Suzanne Kessler is an American social psychologist known for the application of ethnomethodology to gender. She and Wendy McKenna pioneered this application of ethnomethodology to the study of gender and sex with their groundbreaking work, Gender an Ethnomethodological Approach. Twenty years later, Kessler extended this work in a second book, Lessons from the Intersexed.
In the Dominican Republic, güevedoces are children with a specific disorder of sex development. Güevedoces are classified as girls when they are born but, around the age of 12, they start developing male genitalia. This is due to a deficiency in the production of 5α-reductase, an enzyme involved in the metabolism of testosterone to dihydrotestosterone. The same phenomenon occurs in Papua New Guinea, where it is called kwolu-aatmwol by the Sambia people, and in Turkey.
