Puberty blockers are reversible: what the science says

Dr Helen Webberley on LBC: trans healthcare, with Tom Swarbrick, LBC

What people think

Puberty blockers cause permanent changes to the body. Once a child starts them, something irreversible has already happened, and the effects cannot be undone.

What is actually true

What I was saying there is exactly what the Endocrine Society and WPATH have documented: when you stop a puberty blocker, the gonads resume their function. The ovaries or testes wake back up and begin producing hormones again. That is not a belief or a campaign position, it is the pharmacology of how these medications work, and it has been understood for decades, including in the treatment of precocious puberty in children who have nothing to do with gender. The reversibility is not in question among the people who actually study this. What is in question, politically, is whether trans young people should be allowed to benefit from it.

Whatever brought you here, I'm glad you came. Tell me what is on your mind and we can talk it through.
