Concepts and Updates in the Evaluation and Diagnosis of Common Disorders of Sexual Development.

Abstract

Our understanding of disorders of sexual differentiation (DSD) has evolved from aberrations of human genital development to a broad group of complex disorders of etiological and functional significance. The unique challenge of DSD conditions is that they create a cause for significant angst and concern for both parents and physician, as they frequently lead to questions with regards to gender assignment, surgically corrective options, long-term outlook regarding gender identity, and reproductive potential. To further add to the burden, many patients who present with genital abnormalities do not have a clear explanation as to the underlying basis of their disorder. This review looks at DSD from a pediatric urology point of view with emphasis on evaluation, diagnosis, and algorithm for work-up. We also discuss novel genetic analysis techniques and their value in diagnosis. Overall, this is an all-encompassing review on a diagnostic approach to DSD, with inclusion of recent developments and controversies, which will benefit urologists and other physicians alike.
