title: Genetic and physical studies of male children with psychological gender disturbances.
abstract: Twelve male children were diagnosed with psychological gender disturbances by 3 independent clinical psychologists using independent data sources focusing on behavioural deviance from  normal comparison groups, on conventional psychological testing, and on parent report instruments which had been validated on normal comparison samples. These children received a paediatric evaluation consisting of a medical history, complete physical examination, chromosome analysis including 2 cells karyotyped and 15 counted, and sex chromatin studies. All gender disturbed boys were found to be normal genetically and physically with the exception of one subject with one undescended testicle.
