Intersex people are born with sex characteristics (such as genitals, gonads, and chromosome patterns) that "do not fit the typical definitions for male or female bodies". They are substantially more likely to identify as lesbian, gay, bisexual, transgender or queer (LGBTQ) than endosex people. According to a study done in Australia of Australian citizens with intersex conditions, participants labeled 'heterosexual' as the most popular single label (selected at 48%) with the rest being scattered among various other labels. According to another study, an estimated 8.5% to 20% experience gender dysphoria. Although many intersex people are heterosexual and cisgender, and not all of them identify as LGBTQ+, this overlap and "shared experiences of harm arising from dominant societal sex and gender norms" has led to intersex people often being included under the LGBTQ umbrella, with the acronym sometimes expanded to LGBTQI. Some intersex activists and organisations have criticised this inclusion as distracting from intersex-specific issues such as involuntary medical interventions.
