Bilateral Leydig cell tumors and male infertility: case report.
A 38-year-old man with a complaint of male infertility due to azoospermia was found to have bilateral Leydig cell tumors. The tumors were synchronous, not clearly palpable and not diagnostic by ultrasonography. The serum level of estradiol was remarkably increased, and that of testosterone was above the normal upper limit. Tumors of 0.8 cm in diameter were detected by scrotal exploration, and findings of Leydig cell tumors in the bilateral testes were confirmed by histologic and electron-microscopic studies.
