A transgender exhibition has returned to The Science Museum after it was initially removed following complaints it was ignoring biology.

The controversial cabinet has since been reworked but campaigners say it is "more insidious" and pushes a "sexist view of the world."

The original display showed a fake penis and chest-binding equipment with the title "Boy or Girl?"

Following accusations the cabinet was pushing gender-ideological "propaganda", it was removed.

The new display explains why some people transition to their preferred gender, and how puberty blockers are sometimes used to achieve this.

A sign states "some people’s gender doesn’t match the sex they were born into."

It adds that “they may make changes to live their life in a way that better aligns to that identity. This is sometimes called transition.”

"They have made it less in your face but in some ways that’s more insidious," Helen Joyce, author and director of advocacy at the campaign group Sex Matters told The Telegraph.

"They have made it less in your face but in some ways that’s more insidious.

“The fake penises and chest-binding equipment may be out of sight, but so are the obvious warning signs for parents.”
