Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomized, double blind, placebo-controlled study of the effects of transdermal estradiol versus placebo on cognitive flexibility, reward processing, and eating disorder pathology in hypoestrogenemic female adolescents and young adults (ages 14-35 years) with an eating disorder characterized by extreme dietary restriction and/or excessive exercise. Subjects will be randomized 1:1 to 12 weeks of transdermal estradiol with cyclic progesterone or placebo patches and cyclic placebo pills.
