What is the most common hormone secreted by a Sertoli-Leydig cell tumor?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Androstenedione

Answer: (C)

Sertoli-Leydig cell tumors, also known as Sertoli-Leydig cell tumors of the ovary, are sex-cord-stromal tumors that typically arise in reproductive-age women. These tumors have the capability to produce and secrete male hormones, specifically androgens. The predominant androgen produced by Sertoli-Leydig cell tumors is testosterone, which is significant in the context of the various clinical manifestations these tumors can cause, such as virilization in women. In terms of sex steroid hormone production, Sertoli cells primarily secrete inhibin, while Leydig cells produce testosterone. In Sertoli-Leydig cell tumors, the neoplastic cells can exhibit both Sertoli and Leydig cell characteristics, leading to an increased synthesis of testosterone. The presence of high levels of testosterone can lead to various symptoms associated with androgen excess, such as hirsutism or menstrual irregularities. While these tumors may also produce other hormones to some extent, the most common hormone secreted by a Sertoli-Leydig cell tumor is indeed testosterone, making it the correct answer in this context.
