摘要

Study Objective

To understand the timing and factors affecting diagnosis of phenotypically female 46XY children.

Design, Setting, and Participants

We studied all phenotypically female 46XY children who attended our multidisciplinary disorders of sexual differentiation (DSD) clinic in Nottingham England in a 3-year period since its inception. Case notes from a prospectively maintained database were reviewed and data were analyzed on the age at presentation, family history, findings on genital examination, and underlying endocrine abnormality.

Results

Eleven children were studied, all of whom were being raised as girls. The median age of presentation was 18 months (range birth-15 years). Although the newborn examination detected the possibility of DSD in only 3 cases; 10 of 11 children had at least one significant abnormality in their external genitalia at presentation.

Conclusion

Careful neonatal genital examination can identify children with DSD. However, not all children with these conditions are identified early. Early diagnosis, when possible, is important, as it has the potential to make the management of this difficult condition more straightforward.
