are safe and have been used for years, but not in quite the same way that they are used for transgender people. Usually, hormone blockers are used to block one or two excessive hormones, but in Poppy’s case, the medication will block
all her secondary sex hormones. As a doctor, Rosie is concerned about the long-term implications of permanently shutting down one of the body’s natural processes.
