Intersex

What it means

Intersex is about biological variation — chromosomes, hormones, genitals or internal organs — not gender identity or orientation. Intersex people can be any gender and any orientation. Some variations are visible at birth; others are discovered at puberty, during fertility testing, or never. Estimates of how common intersex variations are range up to about 1.7% of people, depending on definitions.

Where the term comes from

'Intersex' replaced the older, stigmatising term 'hermaphrodite' in medical and community use during the 20th century. Intersex advocacy groups have campaigned since the 1990s to end unnecessary surgeries on infants.

How it can look in real life

• A woman who learned at 16 that she has androgen insensitivity syndrome.
• Someone with Klinefelter syndrome (XXY) who identifies as a man.
• An intersex adult who campaigns against non-consensual childhood surgery.

These are examples, not requirements. People who use the same word can have very different histories, relationships and preferences — and nobody needs a particular amount of experience to know what fits.

Common myths

• Intersex is a gender identity — it's a set of physical variations.
• Intersex people need surgery — many variations are healthy, and advocates call for delaying non-urgent surgery until a person can consent.
• Intersex is extremely rare — it's more common than many people think.

Talking about it with a partner

Intersex people decide what to share and when. If a partner discloses, listen without medicalising or asking for details they haven't offered.

It helps to talk about specifics — what closeness, touch, exclusivity and privacy mean to each of you — rather than expecting a label to answer those questions. Either person can decide something isn't right for them, and nobody owes intimacy to keep a relationship going.

Sexual-health notes

• Care should be tailored to a person's actual anatomy and hormones.
• Many intersex adults have experienced medical trauma; trauma-informed providers matter.
• Fertility varies by variation — specialist advice helps if it's relevant.

Health advice should follow your body and the activities you actually do, not a label. A clinician can help with testing, vaccines and barriers — and you deserve care that doesn't judge.
