Puberty Blockers Clinical Trial

Helen Morgan Excerpts

Monday 23rd March 2026 Westminster Hall

[Helen Morgan (North Shropshire) (LD)]

It is a pleasure to serve with you in the Chair, Mr Mundell. I thank my hon. Friend the Member for Caithness, Sutherland and Easter Ross (Jamie Stone) for his opening speech, as well as the compassionate and balanced nature with which he introduced the debate.

Liberal Democrats have been arguing for many years that improved access to better specialist healthcare services for children and young people struggling with their gender identity is extremely important. These young people have been badly let down by low care standards, extremely long waiting lists and an unacceptably toxic public debate.

Up front, I want to be clear that my party’s position is that any treatment and the approval of a trial must always be led by clinical, expert evidence, and not by personal belief, however sincerely that belief is held. For these reasons, we welcomed and continue to welcome the call in the Cass review for a clinical trial.

Following the closure of the GIDS clinic, which was rated inadequate by the Care Quality Commission, it is clear that change is needed. Under the previous system, more than 5,000 young people were stuck on a waiting list for a single clinic, each waiting an average of three years for just their first appointment.

We have consistently campaigned for real action to tackle the shocking waiting times across the NHS, whether for cancer patients or mental health referrals, and the importance of cutting these wait times is equally pressing for gender identity services. We have been pressing for new services with more specialist clinicians who can provide children and young people with the appropriate and high-quality care that they need. Liberal Democrats welcome the NHS’s move to create new regional centres to offer this healthcare to the young people who need it. However, as far as I am aware, only two have opened so far—one in London and one in the north-west. We would like confirmation of when more centres will open.

Young people who are stuck on these waiting lists will still have to wait a very long time. At such a distressing point in their lives, the three-year average wait for someone to see a specialist must feel like an eternity—for them and their family. The Government must show true urgency in opening these services to prevent more children being further denied the care that they need.

It is right that treatment should first be based on talking therapies. That gives those receiving treatment and their families the time, space and clarity to make informed decisions about their future. However, young people must be able to start talking therapy when they need it as a matter of urgency, not after languishing for years on waiting lists.

Following the Cass review, the Secretary of State for Health and Social Care announced the launch of an NHS clinical trial to investigate the impact of puberty blockers, alongside an indefinite ban on puberty blockers as treatment for gender dysphoria or gender incongruence. That trial has now been paused. It is crucial that decisions on treatment are made by expert clinicians and based on the best possible evidence, but we need the NHS to build up that evidence base effectively and safely.

In that vein, we are supportive of the Secretary of State’s decision to pause the trial while the concerns raised by the MHRA are thoroughly assessed. I am calling on the Government to publish how the MHRA arrived at its decision to pause the trial, so there can be confidence that the decision was led by clinical evidence. As with any medical treatment, it is crucial that decisions are led by expert clinicians following the evidence on safety and effectiveness. Research should also take into account the personal experiences of those who have previously used these services.

This debate should not be an ideological one; it is a debate about the quality of healthcare we provide to people who are in desperate need. All trans and non-binary people should be able to access the high-quality healthcare they deserve. The Liberal Democrats call on the Government to make tackling the unacceptable waiting times a priority. To take the urgent action that is needed, the Government must commit to NHS trials and adult services for trans and non-binary people that will expand the timely provision of appropriate specialist healthcare.

The Government must ensure trans people can access high-quality healthcare in the manner we expect for all patients. Medical decisions should be made by patients and doctors together and informed by the best possible evidence. The Government must support research through effective and safe methods using international best practice to improve our evidence on the safety and efficacy of potential treatments.

One thing is certain: in a debate where the wellbeing of many young people is at risk, decisions should not be led by ideology. We cannot let a toxic public debate threaten the wellbeing of vulnerable individuals. The Government must prioritise clinical evidence and put the interests of patients at the heart of the decision-making process, as we do in all areas of healthcare.
