Testis tumors are extremely rare tumors, especially if they are bilateral, interstitial tumors. We present a case with bilateral Leydig cell tumors, which were detected incidentally. First, radical left orchiectomy was performed and pathologic diagnosis was Leydig cell tumor. One week later, partial right orchiectomy was done. The diagnosis was the same. After the 12-month follow-up, no recurrence or metastasis was detected. We suggest organ-sparing surgery as an alternative in the treatment of bilateral Leydig cell tumors especially for young males, since this surgical approach prevents hormonal replacement therapy and maintains fertility and potency.
