The major global medical association for endocrinologists will review its clinical guidelines for gender-affirming care, the Endocrine Society told CNN on Monday. Despite recent moves by some US states to restrict or ban such care, the society said it’s a routine update that was not prompted by politics. The society’s guidelines help the organization’s 18,000 members – doctors, nurses, educators and students who focus on hormone-related health – determine the best practices to provide appropriate care for people who are transgender and gender-diverse. The organization said it will take about three years for the guidelines to come together. Gender-affirming care is medically necessary, evidence-based individualized care that uses a multidisciplinary approach to help a person transition from their assigned gender – the one the person was designated at birth – to their affirmed gender – the gender by which one wants to be known.
