A community and umbrella term for innate variations in sex characteristics.

Intersex
An umbrella for innate variations in sex characteristics—such as chromosomes, hormones, gonads, internal reproductive anatomy or genitals—that do not fit typical female or male patterns.
Identity & diversity
In brief
Natural variation in sex characteristics, with individual language and healthcare needs.
Intersex is about sex characteristics, not one gender identity or sexual orientation. Some people prefer intersex, variations in sex characteristics, differences in sex development, a specific diagnosis or another term. Many variations are discovered at birth, puberty, during fertility investigation or incidentally; some never require treatment.
Differences or disorders of sex development, clinical language accepted by some people and rejected by others.
Gender differing from sex assigned at birth; distinct from intersex, though a person can be both.
A gender outside exclusive woman-or-man categories; it does not describe sex characteristics.
Many variations
Intersex traits include diverse chromosomal, hormonal and anatomical patterns rather than one body type. External appearance alone may not reveal them.
A variation may have no health effect or may require endocrine, surgical, fertility or other specialist follow-up. The specific diagnosis, not the umbrella alone, guides care.
Identity and language
Most intersex people are registered and identify as women or men; some identify as non-binary or another gender. Intersex status does not predict pronouns or orientation.
Ask what terminology a person prefers. Avoid outdated sensational language and requests to inspect or explain private anatomy.
Consent and healthcare
Tests and interventions should be explained in accessible language, with the person involved according to age and capacity. Irreversible procedures raise particular consent and long-term outcome questions.
Records, photographs and genetic information are highly sensitive. Share only what is necessary and agreed or lawfully required.
Sexual and reproductive health
Puberty, menstruation, hormones, fertility, sensation and sexual comfort vary by condition and treatment history. General assumptions are unsafe.
Specialist teams can discuss monitoring, fertility and options without defining a person's worth by reproductive capacity or typical appearance.
Non-graphic examples
What the umbrella may include
- Learning of a chromosome variation during fertility tests.
- Preferring a condition-specific term rather than intersex.
- Being an intersex woman with a female legal sex.
- Being both intersex and non-binary.
- Requesting privacy for genetic and anatomical information.
