Background: Steroidogenic factor 1 (encoded by the NR5A1 gene) is a transcriptional regulator of genes involved in gonadal development and steroidogenesis. Mutations in NR5A1 are associated with a wide phenotypic spectrum in 46,XY individuals ranging from partial/complete gonadal dysgenesis or anorchia, ambiguous genitalia, hypospadias, to infertility. However, little is known about the longitudinal course of endocrine markers for Sertoli and Leydig cell func...
