Hormone Therapy - Treatment that adds, blocks, or removes hormones. For certain conditions (such as diabetes or menopause), hormones are given to adjust low hormone levels. Hormones can also cause certain cancers (such as prostate and breast cancer) to grow.
Feminizing hormone therapy is used to induce physical changes in your body caused by female hormones during puberty (secondary sex characteristics) to promote the matching of your gender identity and your body (gender congruence). If feminizing hormone therapy is started before the changes of male puberty begin, male secondary sex characteristics, such as increased body hair and changes in voice pitch, can be avoided. Feminizing hormone therapy is also known as gender-affirming hormone therapy.
During feminizing hormone therapy, you'll be given medication to block the action of the hormone testosterone. You'll also be given the hormone estrogen to decrease testosterone production and induce feminine secondary sex characteristics. Changes caused by these medications can be temporary or permanent. Feminizing hormone therapy can be done alone or in combination with feminizing surgery.
Masculinizing hormone therapy is used to induce the physical changes in your body caused by male hormones during puberty (secondary sex characteristics) to promote the matching of your gender identity and body (gender congruence). If masculinizing hormone therapy is started before the changes of female puberty begins, female secondary sex characteristics, such as the development of breasts, can be avoided. Masculinizing hormone therapy is also known as gender-affirming hormone therapy.
During masculinizing hormone therapy, you'll be given the male hormone testosterone, which suppresses your menstrual cycles and decreases the production of estrogen from your ovaries. Changes caused by these medications can be temporary or permanent. Masculinizing hormone therapy can be done alone or in combination with masculinizing surgery.
