"Intersex people may face discrimination and stigma in the health system, in many cases being subjected to lack of quality of care, institutional violence and forced interventions throughout their lifetime (178, 262, 263).

A major concern for intersex people is that so-called sex normalizing procedures are often undertaken during their infancy and childhood, to alter their bodies, particularly the sexual organs, to make them conform to gendered physical norms, including through repeated surgeries, hormonal interventions and other measures. As a result, such children may be subjected to medically unnecessary, often irreversible, interventions that may have lifelong consequences for their physical and mental health, including irreversible termination of all or some of their reproductive and sexual capacity. Medical procedures may sometimes be justified in cases of conditions that pose a health risk or are considered life-threatening. Such procedures, however, are sometimes proposed on the basis of weak evidence, without discussing and considering alternative solutions (178, 262, 264–270)."

"In many countries, transgender and often also intersex persons are required to undergo sterilization surgeries that are often unwanted, as a prerequisite to receiving genderaffirmative treatment and gender-marker changes (16, 64).

According to international and regional human rights bodies and some constitutional courts, and as reflected in recent legal changes in several countries, these sterilization requirements run counter to respect for bodily integrity, self-determination and human dignity, and can cause and perpetuate discrimination against transgender and intersex persons (15, 64, 140, 141–146)."

"It has been recommended by human rights bodies, professional organizations and ethical bodies that full, free and informed consent should be ensured in connection with medical and surgical treatments for intersex persons (64, 150) and, if possible, irreversible invasive medical interventions should be postponed until a child is sufficiently mature to make an informed decision, so that they can participate in decision-making and give full, free and informed consent (15, 149)"
