Hundreds of young transgender people are regretting their decision to change their sex as they are now seeking help to return to their original sex, a woman who is setting up a charity has told Sky News.

Charlie Evans, 28, was born female but identified as male for nearly 10 years before detransitioning.

Sky reports that the number of young people seeking gender transition is at an all-time high but very little is heard about those who may come to regret their decision.

There is currently no data to reflect the number who may be unhappy in their new gender or who may opt to detransition to their biological sex.

Charlie detransitioned and went public with her story last year – and said she was stunned by the number of people she discovered in a similar position.

“I’m in communication with 19 and 20-year-olds who have had full gender reassignment surgery who wish they hadn’t, and their dysphoria hasn’t been relieved, they don’t feel better for it,” she says.

Charlie says she has been contacted by “hundreds” of people seeking help – 30 people alone in her area of Newcastle, United Kingdom.

“I think some of the common characteristics are that they tend to be around their mid-20s, they’re mostly female and mostly same-sex attracted, and often autistic as well.”

She recalls being approached by a young girl with a beard who hugged her after giving a public talk, who explained she was a destransitioned woman too.

“She said she felt shunned by the LGBT community for being a traitor. So I felt I had to do something.”

Charlie is now launching a charity called The Detransition Advocacy Network

Sky News spoke with one person who has contacted Charlie’s network for help but does not want her name mentioned.

Ruby (not real name) is now 21 but first began identifying as male at 13.

After taking testosterone her voice got a lot deeper, she grew facial hair and her body changed.

She had been planning to have surgery to remove her breasts this summer.

However, in May, Ruby voiced the growing doubts she had been harbouring and made the decision to come off testosterone and detransition to identify as female.

“I didn’t think any change was going to be enough in the end and I thought it was better to work on changing how I felt about myself, than changing my body,” says Ruby.

“I’ve seen similarities in the way I experience gender dysphoria, in the way I experience other body image issues.”

Ruby explains she has also had an eating disorder but she does not feel that issue was explored in the therapy sessions she had when she went to gender identity services.
