Retrospective Analysis of the Neonatal Management of Patients with an Antenatal Diagnosis of Genital Development Variation At the Hospital of Lyon

Variations in genital development (VDG) account for 0.5% to 1% of births. Advances in ultrasound techniques, as well as in prenatal diagnosis techniques, particularly in genetics, have led to improvements in the prenatal diagnosis of these pathologies. However, to date, there is no consensus on etiological research and standardized management of these patients and their families, once VDG has been detected. The value of multidisciplinary management has already been demonstrated, but a number of grey areas remain: the frequency of false-positive ultrasound findings, the place of invasive antenatal diagnostic tests, the role left to parents during the diagnostic process, the frequency of associated malformations discovered post-natally, and how to prepare for immediate management at birth. The aim of this study is to improve the management of patients and their families as soon as a Disorders of Sexual Development is detected antenatally. The primary objective is to describe the management, particularly complementary investigations performed in the antenatal management of ultrasound diagnoses of Disorders of Sexual Development over the last 10 years. The secondary objectives are : * To determine the correlation between pre- and post-natal morphological phenotype and the proportion of false positives in antenatal ultrasound diagnosis. * To characterize prenatally diagnosed Disorders of Sexual Development * To determine the proportion of isolated prenatally-diagnosed Disorders of Sexual Development that turn out not to be isolated during postnatal follow-up. * The evaluation of the care pathway : * To establish the frequency of prenatal psychological support for parents * To establish the role of parents in prenatal diagnosis strategy decisions at our center
