What is gender identity?

At 72gender.com, we explore the concept of gender identity and provide information about the 72 recognized genders beyond just male and female. Each gender is explained in detail, offering insights into its meaning and how it fits within the broader spectrum of gender diversity.

Gender identity refers to how a person experiences and defines their own gender. It may align with or differ from the sex assigned at birth and is not limited by anatomy or genetics. Everyone’s gender identity is personal, valid, and deserves respect.

Whether you’re curious, questioning, or looking to support others, our platform offers a clear and respectful overview of the 72 gender identities and what they represent.

How It Works

Gender identity

The term ‘gender identity’ (also called ‘psychic identity’) refers to the inner gender experience of feeling man/boy, woman/girl, alternately or (neither) both. Gender identities are usually divided into two large groups: cisgender and transgender. 

Gender expression is an important aspect of gender identity that refers to the ways in which individuals present themselves to the world through clothing, hairstyles, and behavior. It is not necessarily linked to a person’s sex assigned at birth and may include a range of masculine, feminine, or non-binary expressions. By embracing and celebrating diverse gender expressions, we can create a more inclusive and accepting world for everyone. If you’re looking to explore your own gender expression, consider trying out different styles and experimenting with your presentation to find what feels authentic to you. Remember to seek support from trusted friends and professionals, and don’t be afraid to embrace your true self!

Gender identity in cisgender persons

In cisgender persons, the gender identity and the assigned birth sex correspond. For example, you are born with female sex characteristics and you also feel like a girl/woman; or you are born with male sex characteristics and you also feel like a boy/man.

Being cisgender is the prevailing norm and creates a false assumption that everyone’s gender identity corresponds to their assigned birth sex. The cisgender norm (also called ‘cisnormativity’) assumes that there are only two gender identities: on the one hand, men, on the other hand, women. This is called ‘a dual or gender-binary view’ and is at odds with the existence of gender diversity. After all, there is a great variety of gender identities and the way in which people identify themselves.

Gender identity in transgender people

It is also possible that the gender identity and the assigned birth gender are more or less in conflict with each other, or simply do not (completely) coincide. A wide diversity is possible in the gender experience of being a boy or/or girl, man or/or woman. However, it is important to know that this is not an abnormality or disease, but a normal variation of being human.

The term “transgender” therefore covers a diverse population consisting of people with a binary gender identity, including trans men and trans women, as well as people with a non-binary gender identity, including non-binary people.

Expression

Gender expression refers to the way you express your gender experience: what roles do you take on in daily life? What clothes do you wear? How do you behave towards others? Gender expression is what the outside world sees of you, as opposed to gender identity which is invisible and takes place inside.

Identity

Gender is a social construction and refers to the cultural, social and psychological interpretation of femininity and masculinity within a society. It includes all expectations, values and norms that we associate with a particular gender. This interpretation is highly context- and time-dependent.

attraction

Being romantically and/or sexually attracted to other people is called sexual/romantic preference or sexual/romantic orientation. A distinction is often made between LGB (gay, lesbian, bi) and straight, but there are many more expressions of a person's sexual orientation. Think of pansexuality, asexuality, and so on.

Sex

The sex is determined at birth. It is often based solely on what doctors observe visually at birth, and is recorded as such on the birth certificate. Doctors use standards about what a body should look like in order to register a newborn as a boy or girl. Usually people think that there are only two options: a male or female birth gender – and this is legally registered as well.

Variations in Sex Characteristics

Scientific research shows that gender has many more variations. Sex is after all not only determined by external sexual characteristics (the so-called ‘phenotypic’ sex). The gonadal sex (the sex based on the gonads present) is also important, as is the genetic sex (presence of X and/or Y chromosomes).

These aspects are possible in various combinations. These variations on the known binary classification (M/F) are referred to as “variations in sex characteristics” (“variations in sex characterisitics”). One speaks of variations in sex characteristics when a person’s physical sex characteristics do not fully fit within the norms set by the medical world and/or within the prevailing socio-cultural view of gender.

How common are variations in sex characteristics?

Prevalence is difficult to determine because not all variations are (immediately) visible, and because there is little international consensus about which variations should be counted.

According to the Intersex Society of North America (ISNA), in 1 in 1,500 to 1 in 2,000 births, an expert on gender differences is consulted because the external genitalia are unclear. But there are many more people who are born with more subtle forms of gender variations, some of which are not even apparent until much later in life. In the groundbreaking article “How Sexually Dimorphic Are We? Review and Synthesis” by Blackless et al. (2000) provides an overview of the estimated numbers.

Because not all variations in sex characteristics present the same physical challenges or are even identified, the estimated figure even rises to 1.7% of the population. The chance of a variation in sexual characteristics would then be about as frequent as the chance of having red hair. In short, the exact number of intersex people is not known, but estimates range from 57,000 Belgians and 85,000 Dutch to slightly more than double.

Identity, expression, attraction and sex

Gender Is More Than Either/Or

Many people grow up hearing that gender is simple: boy or girl, man or woman, masculine or feminine. But for many individuals, gender is much more complex, personal and layered than a strict either/or framework. Gender is not always binary. For some people, it can be an and/and experience: a combination of identities, feelings, expressions and ways of being that may shift, grow or change over time.

Understanding gender in this broader way creates room for people whose experiences do not fit neatly into traditional categories. Someone may feel connected to more than one gender, move between different gender experiences, feel partly connected to a gender, or feel outside gender altogether. These experiences are valid and are part of the wider spectrum of gender identity and gender diversity.

Exploring Gender Can Bring Questions

Exploring your gender can raise questions, doubts, curiosity and uncertainty. You may wonder which words fit, whether your feelings are “real enough,” or whether your understanding of yourself might change later. These questions are common. Gender exploration is not always a straight path, and it does not need to lead to one final label immediately.

Some people find a gender identity term that feels right very quickly. Others need time to read, reflect, try different language, talk with trusted people or simply sit with their feelings. Both experiences are normal. There is no deadline for understanding your gender, and there is no single correct way to describe who you are.

Why People Hesitate to Talk About Gender

Many people feel nervous when talking about gender, sexuality or LGBTQ+ topics. This can happen in everyday conversations, classrooms, workplaces, healthcare settings or even anonymous surveys. People may worry about saying the wrong thing, using outdated terminology, asking a question in the wrong way or unintentionally offending someone.

These concerns are understandable. Language around gender continues to evolve, and not everyone learns the same terms at the same time. What matters most is the willingness to listen, learn, correct mistakes and approach the conversation with respect. You do not need to be perfect to be supportive.

Creating Space for Curiosity and Respect

Respectful dialogue starts with curiosity, patience and openness. Asking thoughtful questions, learning inclusive language and making room for different experiences can help build understanding. This is true whether you are exploring your own gender or trying to better understand the experiences of someone else.

At the same time, it is important to remember that no one is required to explain their identity, body or personal history. Good conversations about gender are based on respect, consent and care. Listening is often just as important as asking questions.

There Is No One Right Way to Experience Gender

Gender can be stable, fluid, simple, complex, deeply felt, quietly present or difficult to define. Some people identify strongly with one gender. Others experience gender as changing over time. Some use terms such as non-binary, genderfluid, agender, bigender, demigender, transgender or another identity. Some people prefer not to use a label at all.

All of these experiences can be meaningful. What matters is that people have the freedom to understand and express their gender in a way that feels honest and safe for them.

Gender Exploration Is a Valid Journey

Exploring gender can be an important part of self-discovery. It can help people better understand their feelings, their expression, their relationships and the language that brings them comfort. It can also help others become more empathetic and aware of the diversity of human experience.

There is no need to rush the process. Learning about gender, asking questions and allowing space for change can be valuable steps toward greater self-understanding and connection with others.

Gender is not only about fitting into a category. It is also about understanding, expression, respect and the freedom to be seen as yourself.

Have You Ever Questioned Your Gender Identity?

As awareness of gender diversity continues to grow, more people feel able to explore their gender identity with openness and support. Questioning your gender can sometimes feel confusing, especially when old expectations, social norms or cissexism are challenged. But questioning is not a problem — it can be a natural and meaningful part of self-discovery.

Gender exploration can happen at any age and in many different ways. There is no fixed timeline, no pressure to choose a label, and no single “right” way to feel. Your understanding of gender may stay the same, shift over time or become clearer through reflection. Taking space to explore can lead to deeper self-knowledge, greater confidence and a stronger connection to who you are.
