What is the Origin of Gender-Affirming Hormones?

The term reflects the medical and social evolution of care for transgender and gender-diverse individuals, moving from older, pathologizing language to a framework centered on affirmation and health. The use of sex hormones for this purpose is rooted in classical endocrinology, applying the known effects of testosterone and estrogen on human physiology. This practice acknowledges the profound interplay between hormones, gender identity, and mental health.

What is the Mechanism of Gender-Affirming Hormones?

GAH therapy functions by altering the body's hormonal milieu to induce secondary sex characteristics congruent with the affirmed gender. Estrogen therapy, for example, suppresses endogenous testosterone and promotes breast development and fat redistribution to a more feminine pattern. Conversely, testosterone therapy suppresses ovarian estrogen production and promotes virilization, including deepening of the voice and increased muscle mass. These hormones exert their effects by binding to specific nuclear receptors, modulating gene expression, and driving the physiological changes that affirm gender identity.

This medical intervention is a crucial component of comprehensive transgender healthcare, helping to alleviate gender dysphoria and improve psychological well-being.
