JK Rowling has shared a series of articles on Twitter relating to the transgender debate and warned of a coming "scandal" she predicted could affect young people.
The Harry Potter author, 54, has been at the centre of a row about trans rights and accused of being transphobic, an allegation she strongly denies.
Rowling previously said in an essay on her website that she was partly motivated to speak out about the issue because of her experience of abuse and sexual assault.
Writing on Twitter on Saturday, Rowling said she had been contacted by numerous healthcare professionals in support of her recent comments.
She said: "Since speaking up about gender identity theory, I've received thousands of emails – more than I've ever had on a single subject.
"Many have come from professionals working in medicine, education and social work. All are concerned about the effects on vulnerable young people.
