Testicular Preservation in 46 XY Denys-Drash Syndrome: A Report of Two Cases.

Denys Drash Syndrome (DDS) is a rare combination of genital and urinary anomalies that are mostly associated with malignancy. We report 2 patients who presented with genital ambiguity and were diagnosed as 46-XY DDS. During the discussion of the management plan, parents preferred to keep the gonads to preserve its endocrinal function for future sexual development. However, both patients developed primary hypogonadism at puberty and required testosterone supplementation. Persevering gonads in such patients had no endocrinal benefits but put the patients at risk of malignant transformation.
