Are our bodies really "programmed" during puberty?
I saw this study (https://pmc.ncbi.nlm.nih.gov/articles/PMC8247856/) on transgender teenagers that found that people transitioning mid-to-late puberty overwhelmingly grew in the way of their birth sex despite hormone therapy. The author says this is because of hormone exposure during tanner one biasing their bodies towards male/female growth but is this actually something that exists? If so, is this why some people have drastic hrt changes and others look like their birth sex until they get surgeries?
