Hormone Levels During Normal Puberty in Cisgender Girls
By Aly | First published April 29, 2020 | Last modified April 7, 2023
Preface
This is a collection of published data on hormone levels throughout normal puberty in cisgender girls. Levels of estrogens (estradiol and estrone), progesterone, and androgens are included. Data are limited to those determined with mass spectrometry-based analytic techniques wherever available.

The lower estradiol and estrone levels in TS5 relative to TS4 are likely due to sampling error.

It should be noted however that this study has been criticized on methodological grounds (Ankarberg-Lindgren & Norjavaara, 2009a; Ankarberg-Lindgren & Norjavaara, 2009b).
