Original title: "Paradiset er ikke til salg: Trangen til at være begge køn" (Paradise is not for sale: The urge to be both sexes) by Preben Hertoft and Teit Ritzau.
"The book sheds light on the concept of gender identity as reflected by transvestites and transsexuals, and attempts to demystify these concepts by means of a series of 'case stories' about how it has really happened to people who have had sex reassignment surgery – among them the famous Christine Jørgensen and Lili Elbe. Preben Hertoft was for many years the head of the Department of Sexology. Teit Ritzau is a doctor and film director."
