[Sexual development of the child and the onset of gender identity]. / Le developpement sexue de l'enfant et la naissance de l'identite sexuee.

In view of the numerous questions raised by the recently disclosed pedophilia, sexual abuses and prostitution of children, it appeared worthwhile to review the recent studies dealing with the child sexual development and the onset of the gender identity. These studies consist partly in retrospective analysis of pathological situations and partly in the analysis of normal development. It appears that the social and emotional surroundings of the child, provided that they were continuous and devoid of ambiguity, play a prominent role in this process. At present, numerous authors consider that gender identity is achieved at about 2 years of age when the child has a harmonious general development. The family physician and the paediatrician are on the first line to detect potential problems provided that they were aware of the main determinants and symptoms involved.
