A new toy billed as the world’s “first transgender doll” has created a buzz on social media.

Thousands of tweets about the product unveiled by the Tonner Doll Company have been posted since it was announced that the doll would make its first appearance at this week’s New York Toy Fair.

The doll is modelled on a teenage activist who was born a boy, but lives as a female. Jazz Jennings shot to fame when she was interviewed about her gender dysphoria by US TV presenter Barbara Walters.

Jazz said: “I was assigned male at birth but was a girl right from the start. I expressed myself as a girl to my family by gravitating towards dolls, dresses, sparkles, and everything feminine.

“I didn’t just like girly objects, but I heavily insisted that I was a girl.”
