Most people who transition to another gender do not have second thoughts. In fact de-transitioning is thought to be relatively rare. There are no accurate figures revealing how many people reverse or change their gender, as academic researchers have never studied a large group of transitioning people over a long period of time – but some studies suggest that fewer than 0.5 per cent of trans people choose to return to the gender they were assigned at birth.

Whatever the numbers, we know that more people are telling their stories. Around the world there are trans men and trans women who have decided to de-transition, and it’s often not an easy choice. Others have chosen to re-identify as non-binary or gender-fluid.

We speak two BBC journalists, Linda Pressly and Lucy Proctor, who’ve made a documentary for the World Service called The Detransitioners. They’ve spent the last year talking to people who had transitioned, but then returned to their birth gender.
