OBJECTIVES METHODS

CONCLUSIONS

The study included 379 patients comprising a wide spectrum of

presenting features, associated with different arrays of

chromosomal abnormalities aiming at studying the prevalence of

Sex chromosomal abnormalities among DSD patients

Patients were subjected to detailed clinical

examination, pubertal staging, cytogenetic and FISH

analysis. Laparoscopy with gonadal biopsy and FISH

on gonadal tissue cells were done when indicated

• Sex chromosomal abnormalities constitute a high proportion of DSD

• Application of ACGH is necessary for diagnosing MCA with DSD

• Detection of Y abnormalities in MGD is necessary for genetic counseling and gonadectomy ( dysgerminoma)
