Clinical Endocrinology. 2022; 96:220–226. PMID: 34596269Brief Summary: This randomized controlled trial evaluated the effects of testosterone and aromatase inhibitor treatment on anthropometric measures, and their correlation with estradiol and testosterone serum levels in boys with constitutional delay of growth and puberty (CDGP), to elucidate the respective roles of the two sex steroid hormones on growth during puberty. The results sugge...
