The Health Service in England has stopped prescribing puberty blockers to children. The British news agency PA reported this on Tuesday, citing NHS England. The drugs that prevent the onset of puberty symptoms such as menstruation, breast growth and voice breakage will only be allowed to be used in clinical studies in the future. An independent review of the health service’s gender identity services had previously criticized a lack of data and evidence about the long-term effects of the drugs. The number of children referred to the relevant service has risen sharply in recent years.

The Conservative government in London welcomed the decision. “We have always been clear that the safety and well-being of children is our top priority, so we welcome this landmark decision,” said Health Secretary Maria Caulfield. Ending the routine prescription of puberty blockers will help ensure care is based on science and expert opinion and in the best interests of the child.

According to PA, fewer than 100 young people in England are currently taking puberty blockers. They should therefore be allowed to continue their treatment. However, the topic is sometimes extremely controversial. Former Conservative Prime Minister Liz Truss is currently campaigning for a complete ban on puberty blockers.
