English: Levels of estradiol (pg/mL), testosterone (ng/dL), and prolactin (ng/mL) during therapy with 1 to 2 mg/day transdermal estradiol gel and 50 mg/day oral cyproterone acetate in 20 transgender women. The mean dosage of estradiol gel increased between 6 and 12 months: "In the [cyproterone acetate] group, at the beginning of [cross-sex hormone therapy], 10 subjects used 2 mg [transdermal estradiol] and 10 subjects used 1 mg [transdermal estradiol] with an increase to 2 mg after a minimum of 6 months of treatment in 5 transwomen."
