Er, if you don&#x27;t block them, 11-year-old trans kids will get the wrong ones. That&#x27;s what puberty does. At a certain age, your body starts producing high amounts of sex hormones. Blocking them means that these kids won&#x27;t immediately develop permanent secondary sex characteristics which don&#x27;t match their gender and would cause then suffering.<p>Surely it is better to block hormones at 11 and then go on the right ones at 16, rather than otherwise needing a mastectomy, facial surgery, vocal surgery, hair removal etc. in later life?
