Triggered by hormonal changes in the brain and body, puberty marks a physical transformation. Oestrogen and testosterone – often called “sex hormones” – drive many familiar changes, such as breast development and periods or a deeper voice and facial hair.
For most young people, the pubertal changes they experience align with their gender. However, for trans and gender diverse adolescents, these changes can be distressing and may lead to a sense of disconnection from their true sense of self.
