Puberty Blockers

Andrew Snowden Excerpts

I am not saying that it is a negative thing; I am trying to explain why we have seen an increase in the numbers of young people with gender dysphoria. I am stating facts; we were just talking about the importance of doing so.

In 2009, only 51 patients were referred to the NHS Gender Identity Development Service for children, of whom two thirds were male. In 2016, there were 1,766 referrals and two thirds of them were female. That is quite the change. There has been an overall surge in the number of children suffering gender distress, but the increase is especially notable among girls. We also see over-representation of neurodiversity, mental health issues and trauma in this group. To put it another way, these children are much more likely to have been in care, to suffer with anxiety and depression, to be autistic and to have been abused. It is a group of incredibly vulnerable children.

GIDS was established in 1989. Its main approach to treatment at that time was therapeutic, referred to as watchful waiting. Early studies from the 1980s showed that in around 85% of cases, the gender incongruence or distress ceased in the child after going through puberty. Later studies reached a similar conclusion, with between 67% and 90% desisting after puberty. Only a small cohort of children continue to experience gender dysphoria or incongruence after puberty, and it was that extremely small group who would likely adopt a permanent trans identity in adulthood.

Recently, the Government announced that they will legislate to prevent under-16s from viewing social media. We already ban under-16s from drinking alcohol and smoking, because we believe that they should be protected from doing things now that may have negative impacts on them later in life, particularly to their health. Does my hon. Friend think that this should sit in that category of protections for children?

[Rebecca Paul]

I completely agree with my hon. Friend; a child of this age cannot possibly consent to the life-changing, irreversible changes that come from puberty blockers. We need to remember that almost all children who start puberty blockers go on to cross-sex hormones, and there is no going back from that.

We need to remember that we have already had a trial in the UK. When we started using puberty blockers in the UK after 2011, the preliminary results came out in 2015-16 and did not demonstrate psychological benefits, with some of the females actually suffering a worsening of symptoms, including a higher incidence of wanting to hurt or kill themselves. The results of the study, which were not formally published until 2020, demonstrated no statistically significant improvement in gender dysphoria or mental health outcomes. It is important to remember the early studies that told us that, in a majority of cases, going through puberty resolved gender distress. It follows, therefore, that stopping or delaying puberty using medication derails that natural desistance, essentially locking in.
