Activity Description

This activity reviews 5-alpha-reductase deficiency, an important cause of ambiguous genitalia in children. Initially, the phenotype of children with 5-alpha-reductase deficiency can vary from underdeveloped male genitalia to fully developed female genitalia. This phenotype may change during puberty, at which point male secondary sex characteristics may develop. This activity will assist practitioners in recognizing when to consider this diagnosis and how to manage it. This activity highlights the critical role of the interprofessional care team in caring for patients with 5-alpha-reductase deficiency.
