What is the definition of intersex?

The I in LGBTQIA+ stands for “intersex.”
Intersex is an umbrella term for differences in sex traits or reproductive anatomy. Intersex people are born with these differences or develop them in childhood. There are many possible differences in genitalia, hormones, internal anatomy, or chromosomes, compared to the usual two ways that human bodies develop.
Some intersex traits are noticed at birth. Others don’t show up until puberty or later in life. Intersex people often face shame—or are forced or coerced into changing their bodies, usually at a very young age. Most surgeries to change intersex traits happen in infancy.
The word intersex also invokes a community. Intersex people are diverse, coming from all socioeconomic backgrounds, races, ethnicities, genders and orientations, faiths, and political ideologies. We are united by
- our experiences living with variations in our sex traits,
- the belief that these differences are a natural part of human diversity,
- the idea that people deserve their own choices about their own bodies.
Is intersex the same thing as being a “hermaphrodite?”
No. “Hermaphrodite” should never be used to describe an intersex person. Some intersex people have reclaimed this word for themselves, but it is usually considered a slur. There are many ways to have an intersex body, but it is not possible for one person to have both a fully developed penis and vagina.
The “h word” comes from mythology. It might suggest that intersex people are monsters, or not of this world. Many intersex people still see this slur used in their medical records.
Is intersex the same thing as “Disorder of Sex Development?”
“Disorder” or “difference of sex development” (DSD) is still a common medical term for intersex traits. Many intersex people reject the term “DSD” because it supports the idea that their bodies are wrong, or up to doctors to “fix.” Advocates in the United States often bring up the fact that until 1973, being gay was considered a mental disorder. Many natural human differences have been framed as medical problems, until communities fought for acceptance.
interACT generally does not use the term DSD. See interACT’s statement on DSD terminology.
How common is intersex?
How many intersex people are born each year? What are the statistics? Even in countries where most births happen in hospitals, these are hard questions to answer. This is largely because no one is required to track this information. But we do know that being intersex is very common.
About 1.7% of people are born intersex. (Compare that to a ~0.3% chance of having identical twins!) 1 in 2,000 babies (0.05% of humans) are born with genital differences that a doctor might suggest changing with unnecessary surgery.
These estimates are based on work by Dr. Anne Fausto-Sterling, who reviewed medical literature from 1955-1998. (Sexing the Body: Gender Politics and the Construction of Sexuality, 2000)
What causes intersex?
Most intersex traits are random, although some do run in families. To be technically specific, some reasons why intersex traits might develop include:
- translocation or deletion of the SRY (“Sex-determining Region Y”) gene,
- variations in the AR (“Androgen Receptor”) gene, an enzyme deficiency leading to increased androgen production, and
- exogenous hormone use during pregnancy.
There’s a long history of abuse in attempts to prevent or “cure” intersex differences. “Why” is a very common question when it comes to human difference. Science is always looking for something to explain natural variation: a gay gene, transgender brain difference, cause of autism, etc. But as intersex people know, “why” can be a very dangerous question. When differences can be seen or measured on bodies, they can be changed. Surgeries to change intersex traits often happen at a young age, without a person’s knowledge or consent.
What is intersex surgery?

Intersex surgeries are non-lifesaving procedures to change natural variations in genital appearance or reproductive anatomy. This is connected to ideas about gender and sexuality, and what “normal” looks like.
Intersex surgeries include
- “reducing” or “repositioning” a clitoris (sometimes called clitoroplasty, or clitoral reduction or recession),
- creating or altering a vagina (vaginoplasty),
- moving a urethra that already works (hypospadias repair), and
- removing the organs that would make sex hormones (gonadectomy).
Infant intersex surgeries often come with serious lifelong emotional and physical consequences, high complication rates, and reduced sexual function. When done without the individual’s informed consent, the United Nations considers these surgeries as human rights violations.
Most intersex surgeries are done when a child is under 2 years old. Surgeries to change intersex traits are often offered to parents, and considered acceptable by some doctors, when a child is very young. This means that people are being denied important choices about their own bodies—choices that can affect fertility, sexual function, and emotional well-being forever.
Some kids may grow up and want to change their bodies, or be glad that their bodies were changed. Many other kids and adults live with incredible pain and trauma because these choices were made for them. When we act early, we never know who will feel which way. Waiting is the best way to avoid irreversible harm.
All parents love their children, and only want what is best for them. Surgeries to change genital appearance may also be wrongly framed by a doctor as an emergency or necessity. Many parents are never told about the high risks of these surgeries, never connected to other families or affected adults, and never told that simply waiting is an option.
interACT is dedicated to supporting all parents and all intersex people without judgement.
How many intersex surgeries happen each year? Are there statistics on intersex surgery?
One intersex surgery without an individual’s consent is one too many.
As of 2021, no U.S. hospitals besides Lurie Children’s of Chicago and Boston Children’s have said that they don’t perform infant genital surgeries. Statistics are difficult to track, because U.S. hospitals are not required to report this information. However, as Kyle Knight, a Human Rights Watch researcher, told BuzzFeed in a 2020 article, “evidence of the rate of [infant intersex] surgeries and the hospitals performing them is hiding in plain sight.”
[Knight] cited a 2016 report published in the Journal of Pediatric Urology that found that 35 out of 37 parents of intersex children had “opted for cosmetic surgery on their children.” A 2017 paper in the Journal of Urology reported nearly identical rates of operations.
Are there any laws about intersex surgery? Is intersex surgery legal?
Infant intersex surgeries violate principles of informed consent, bodily autonomy, and self-determination. They may also be prohibited by female genital cutting laws and regulations against forced sterilization. Even still, some doctors claim parental consent is enough to change the appearance or function of an intersex infant’s genitalia, including cosmetic alterations to the clitoris.
Some countries are taking steps to end infant intersex surgery. For example, the country of Malta and the Indian state of Tamil Nadu explicitly prohibit intersex surgeries without the individual’s informed consent. In 2019, the European Parliament passed a resolution calling on all member states to end surgeries. Portugal, France, and Uruguay have each passed laws to protect intersex people, but which may still stop short of pausing non-consensual surgeries.
Many medical organizations agree that intersex people must be able to make decisions about their bodies, including the American Academy of Family Physicians, GLMA: Health Professional Advancing LGBTQ Equality, the American Counseling Association, and two state-level medical societies (Massachusetts and Michigan).
In the United States, at least 5 states have seen bills to prohibit infant intersex surgery. None have passed yet. In 2018 California passed a non-binding resolution, SCR-110, which was the first successful piece of U.S. legislation to acknowledge intersex human rights violations and harm. Most legislation that interACT sponsors would delay unnecessary medical intervention, including surgeries, to give people choices about their own bodies.

What does intersex look like?
There is no way to “look” intersex. Every person is different. There are over 40 medical terms for the different ways sex anatomy might develop. Here are a few examples, and their common traits:
|Complete Androgen Insensitivity
||Testes, no uterus, sometimes partial vagina, or complete vagina
||If testes are left alone, body goes through puberty via converting testosterone into estrogen
|Partial Androgen Insensitivity
||Vulva and visibly large clitoris, or other differences
||Testes, no uterus, varies
||If testes are left alone, body has varying levels of response to testosterone
|Congenital Adrenal Hyperplasia
||Vulva (labia may be fused), often visibly large clitoris
||Ovaries, uterus, sometimes partial vagina or complete vagina
||May be early, higher testosterone can lead to features such as facial hair, changed fat distribution
||Streak gonads, uterus, sometimes partial vagina or complete vagina
||No puberty because streak gonads do not produce a|
