Transgender doctors in the UK can now choose not to disclose their biological sex, despite a Supreme Court ruling affirming "woman" as defined by biological sex. The General Medical Council (GMC) is updating its policies to make gender recording optional, aligning with data practices for other medical professionals like physician associates. This move stirs debate around patient rights to request a same-sex doctor, although not legally required. The GMC promises to comply with law while reconsidering policy updates. Critics see this as complicating patient knowledge about medical staff sex.
