Testicular adrenal rest tumors in patients with congenital adrenal hyperplasia: 6 years of follow-up.

Background Testicular adrenal rest tumors (TARTs) leading to primary gonadal failure are the main etiology of infertility in congenital adrenal hyperplasia (CAH). We aimed at identifying the evolution of TART and related findings in young CAH patients. Methods Twelve male patients (3-23 years old) with 21-hydroxilase deficiency (11 with classic salt-wasting form) were included.
