High prevalence of testicular adrenal rest tumors, impaired spermatogenesis, and Leydig cell failure in adolescent and adult males with congenital adrenal hyperplasia.
In male patients with congenital adrenal hyperplasia, testicular tumors, or so-called adrenal rest tumors, have been described, but their presence in well controlled patients is thought to be rare. In this study, the prevalence of testicular tumors in 17 adolescent and adult male patients with congenital adrenal hyperplasia (age, 16-40 yr) was investigated. In 16 of 17 patients, one or more testicular tumors, ranging in maximal length from 0.2-4.0 cm, were found on ultrasonography. ⋯ Impairment of Leydig cell function as manifested by decreased plasma levels of T was found in 6 of 17 patients. Semen analysis in 11 patients revealed azoospermia in 3 patients and poor semen quality in 4 patients. We conclude that, when carefully sought for, testicular adrenal rest tumors are frequently present in adolescent and adult males with congenital adrenal hyperplasia and are often accompanied by impaired spermatogenesis and Leydig cell failure.
