Sex and gender have more than one dimension
Many people assume there are only male and female, with everything fixed together at birth. In reality, sexuality comprises several dimensions that are related but do not always determine one another.[1]
Distinguishing them improves communication without ranking which is better and without forcing anyone to adopt a label.[1]
Why it matters for healthcare
Understanding these dimensions reduces assumptions and helps healthcare match each person's needs.[1] For example, cancer screening must be based on the organs a person actually has, not a name or appearance, and prevention advice must be based on actual sexual activities, not identity.
Diversity is not a disease
Diverse gender identities and sexual orientations are not diseases.[2] Survey proportions depend on question wording, terminology and how safe people feel disclosing, so figures vary widely between countries and over time.
The main dimensions
These dimensions are related but do not automatically determine each other[1],[2]:
- Sex characteristics: chromosomes, hormones and reproductive anatomy; some people have intersex variations.
- Gender identity: a person's internal sense of their gender, such as man, woman or another identity.
- Gender expression: clothing, mannerisms and how gender is presented to others.
- Sexual orientation: emotional, romantic or sexual attraction to others.
For example, a trans woman may be attracted to women, men or both, and a man with a gentle style of dress is not thereby gay.
A learning framework, not a diagnosis
These dimensions form an educational framework, not a diagnostic test.[1],[2] In healthcare, the right approach is to ask how someone wishes to be described and to ask only for clinically relevant information, such as anatomy or hormone history.
Beyond the main dimensions
Other important dimensions include desire, the activities people engage in, relationship patterns and social context, all of which affect sexual health.[1]
Multi-axis diagrams used to describe gender are educational frameworks, not a single, universally numbered diagnostic system.[1],[2]
In practice, ask how someone wishes to be described and tailor care to their actual anatomy and needs.[1],[2]
How we care for you at Dr. Kris Clinic
We serve everyone equally and without judgement, ask for your preferred name and terms, and ask only for health information needed for your care, explaining why, in English or Thai.

Frequently asked questions
What is the difference between gender identity and sexual orientation?
Identity is who you understand yourself to be; orientation is who you are attracted to. They are separate dimensions.
Can you tell someone's identity from how they dress?
No. Expression does not reveal identity or orientation.
Why does a doctor ask about anatomy or hormone history?
To choose screening and care that fit your actual body.
Do I need a label for myself?
No. Some people use no label at all, and that is their right.
Respect each person's self-description and assess real health needs.[1] Sexuality has many dimensions, and diversity is not a disease.
