Text by Stop the Blocker Ban.

What’s the deal with puberty blockers?
(and why should you give a shit?)

Puberty blockers are a medication used to delay puberty, for example, GnRH analogues. They have been safely used to treat early/problematic puberty for ~40 years, and are completely reversible.

More recently, puberty blockers have been used to delay puberty in transgender children, preventing them from going through the wrong puberty for their gender. Evidence shows that 97.5% of these children still identify as trans 5 years later. It is not a phase.

In 2024, the Cass Review was published, and the Tory government used it to justify a ban on puberty blockers – but only for trans children. In December 2024, the Labour government made this ban permanent.

Since it was published in April 2024, the Cass Review has been widely criticised for being biased, misleading, methodologically flawed, and inaccurate. Critics include doctors, psychiatrists and the BMA. In short, it’s BULLSHIT!

Evidence shows that having access to gender affirming care – like puberty blockers – leads to better health outcomes, reduced self-harm and suicidality, and improved quality of life. Puberty blockers save lives! Denying trans kids access to healthcare is nothing short of cruel, and totally unjustified.

Trans kids deserve to grow up.
