Puberty is an awkward time for just about everybody, but for transgender teens it can be a nightmare, as they grow overnight into bodies they aren't comfortable with. In a heartfelt talk, endocrinologist Norman Spack tells a personal story of how he became one of the few doctors in the US to treat minors with hormone replacement therapy. By staving off the effects of puberty, Spack gives trans teens the time they need. (Filmed at TEDxBeaconStreet.)
