There is limited evidence that medical transition leads to positive outcomes
A number of different studies have noted the paucity of good quality evidence for transition.
An Australian paper1 states that most available evidence indicating positive outcomes for gender reassignment is of poor quality.
A German study2 “found insufficient evidence to determine the efficacy or safety of hormonal treatment approaches for transgender women in transition”, adding that “[t]his lack of studies shows a gap between current clinical practice and clinical research.”
A British review3 conducted by the National Institute for Health and Care Excellence (NICE) graded certainty of evidence for puberty blocker use as “very low” in every category, including impact on gender dysphoria, mental health, body image, global functioning, psychosocial functioning, cognitive functioning, bone density and adverse effects.
A chapter4 in an edited volume details the low evidence base for treatment pathways employed at the UK’s Gender Identity Development Service, demonstrating how negative evidence was “ignored or suppressed”.
Finally, a systematic review5 commissioned by the World Professional Association for Transgender Health (WPATH) to “systematically review the effect of gender-affirming hormone therapy on psychological outcomes among transgender people” noted that, in some areas, there was low quality or insufficient evidence.

Puberty blockers are more than a ‘pause button’: roughly 98% of children who take them go on to take cross-sex hormones
A 2021 study from the UK1 found that only 1 out of 44 children placed on puberty blockers did not continue to take cross-sex hormones.
Similarly, a Dutch study2 reported that only 1.9% of adolescents who started puberty suppression treatment abandoned this course and did not take cross-sex hormones.
In fact, in a different Dutch study3, “[n]o adolescent withdrew from puberty suppression, and all started cross‐sex hormone treatment, the first step of actual gender reassignment.”
Puberty blockers are drugs which change young bodies in ways we have yet to understand, and may be permanent. This is an experimental treatment program: puberty blockers have never been licensed to treat children with gender dysphoria, in any country.
