Hormone blockers
(noun, plural)
Hormone blockers, also called puberty blockers, are a kind of medication, often prescribed by an endocrinologist, to pre-pubescent and very early puberty transgender children. Hormone blockers delay puberty and prevent the development of secondary sex characteristics by blocking certain hormones from escalating until the child is older and can choose exactly how they want to medically transition. Other older trans people might use hormone blockers to adapt their medical transition, such as using spironolactone (spiro) to block the hormone aldosterone.
e.g. Kai asked to be put on hormone blockers because he was unsure whether he wanted to undergo a testosterone-based puberty.
