Treatment allows trans and gender-expansive people to medically transition or feel more at home in their bodies (see Gender-Affirming Surgery and Transition). Those taking testosterone (masculinizing hormones) may grow more facial/body hair and notice their voices deepening. Those taking estrogen (feminizing hormones) may see some breast growth and decreased libido. Many intersex people take HRT to balance the naturally occurring levels of estrogen and testosterone in their bodies. Benefits of such therapy can include improved mental and physical wellness, and reduced anxiety and dysphoria, for those who experience it.[2],[9]
