Puberty

This chapter is a revised version of the Puberty chapter published in the second edition. The principal changes include updates to the proximate regulators of pubertal hypothalamic GnRH secretion, a brief section on epigenetics, and slight alterations in language to acknowledge that, while biological studies of puberty treat individuals as sexually dimorphic, lived experience varies. New references have been inserted among the pre-existing ones but have not been numbered so that, if revisions are required, the work of formatting and ordering need not take place a second time. They are highlighted in the bibliography to make them easily visible. All tables and figures remain the same except Fig. 5.3. If possible, I would like to include a revised version of this figure that appeared in an Annual Review of Anthropology article (by Reiches). That file is attached below.
