Children expressing confusion about their gender identity has grown extraordinarily in recent years.  Why the sudden rise in the number of boys believing they are girls and vice versa?

Medical intervention can involve puberty blocking drugs, chemical castration by administration of cross-sex hormones, and irreversible surgical modification of genitals.  Those having such transgender "treatment" then require lifelong drugs.

Dr John Whitehall, Professor of Paediatrics at Western Sydney University, questions the need for such massive medical intervention.  The evidence is that most children experiencing “gender dysphoria” grow out of it through puberty, if parents gently support normal development while they watch and wait.

How common are these problems and are they associated with mental problems?  What does medical "treatment" involve?  Dr Whitehall answers these and many other questions on this controversial issue.
