Abstract Subject headings

The overall goal of pubertal sex hormone replacement therapy (HRT) in girls is not only about development of secondary sexual characteristics, but also to establish an adult endocrine and metabolic milieu, as well as adult cognitive function. Estradiol (E2) is the first choice for HRT compared to ethinyl estradiol (EE2). E2 is the most potent endogenous estrogen in the circulation, with established levels during spontaneous puberty. Transdermal E2, compared to oral administration, is the first choice to start pubertal HRT. Transdermal application avoids liver exposure to supraphysiologic estrogen concentrations and provides a more physiologic mechanism for hormone delivery. By cutting E2 matrix patches in doses of 0.05-0.07 µg/kg or administrate E2 gel in doses of 0.1 mg/day, serum concentrations of E2 seen in early spontaneous puberty can be obtained. Patches can be removed in the morning and thereby mimic the normal circadian rhythm. For those clinics with access to sensitive E2 determinations methods (extraction followed by radioimmunoassay or mass spectrometry) monitoring the attained E2 serum levels is recommended in order to optimally mimic the levels seen in early puberty as well as growth velocity, breast and uterus development. Mid- and late pubertal HRT is obtained by increased doses of E2, adding cyclic oral or transdermal progestin, as well as testosterone gel over the pubic area if indicated.
