The medical procedure applied to intersex people is called a s-x change.
I have heard of that. I also have heard that it's more common than people know.
Yes being interex is definitely more common than people think. Variations of intersex may involve genital ambiguitiy and different combinations of chromosomal genotype and sexual phenotype other than the common XY and X-X.(female)
It makes me wonder how many people were born intersex that I know. I wonder if perhaps they are even aware.
Yes those that are intersex may not even be aware but those that are may go to s-x reassignment therapy (another word for s-x change) and this is typically carried out on humans.
Do they ever perform intersex operations on nonhumans?
Sex reassignment therapy
Sex reassignment therapy is the medical aspect of gender transitioning, that is, modifying one's characteristics to better suit one's gender identity. It can consist of hormone therapy to modify secondary sex characteristics, sex reassignment surgery to alter primary sex characteristics, and other procedures altering appearance, including permanent hair removal for trans women.
In appropriately evaluated cases of severe gender dysphoria, sex reassignment therapy is often the best when standards of care are followed. There is academic concern over the low quality of the evidence
Intersex human rights reports
Intersex people are born with sex characteristics, such as chromosomes, gonads, or genitals that, according to the UN Office of the High Commissioner for Human Rights, "do not fit the typical definitions for male or female bodies". Such variations may involve genital ambiguity, and combinations of chromosomal genotype and sexual phenotype other than XY-male and XX-female.
Intersex infants and children may be subject to stigma, discrimination and human rights violations, including in education, employment and medical settings
