Gender-affirming hormone therapy cues changes similar to puberty

When HRT is part of gender affirmation care, people receive regular doses of estrogen or testosterone to alter hormone levels to more closely align with those of cis individuals of that biological sex. HRT may affect voice pitch, body hair, bone density, and more. Many of those changes are not reversible with the cessation of therapy, though the effects may diminish.

Within months of a landmark 2002 study that indicated HRT harms, sales dropped by about half

In the early 2000s, Women's Health Initiative studies indicated HRT increased risk of breast cancer, heart disease, and stroke in some women—so many physicians stopped prescribing it to help with menopause symptoms.

HRT patches are popular partly because they have lower blood clotting risks than oral estradiol
