Ovarian tumours causing masculanization are : Gynandroblastoma Arrhenoblastoma Dysgerminoma Gonadoblastoma
**Core Concept**
Ovarian tumors can cause masculinization due to the production of androgens. The underlying principle being tested is the ability to identify specific ovarian tumors that lead to virilization. **Androgen-producing tumors** are a key concept in gynecologic oncology.
**Why the Correct Answer is Right**
The correct answer is related to tumors that produce androgens, leading to masculinization. **Arrhenoblastoma**, also known as Sertoli-Leydig cell tumor, is a type of ovarian tumor that produces androgens, causing virilization. This tumor type is known for its ability to produce **testosterone** and other androgens.
**Why Each Wrong Option is Incorrect**
**Option A:** Gynandroblastoma is a rare ovarian tumor, but it is not typically associated with masculinization.
**Option C:** Dysgerminoma is a type of ovarian germ cell tumor that does not typically produce androgens.
**Option D:** Gonadoblastoma is a rare ovarian tumor, usually found in individuals with gonadal dysgenesis, and is not typically associated with androgen production.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **arrhenoblastoma** is a tumor that can cause virilization in females, including symptoms such as **hirsutism** and **clitoromegaly**.
**Correct Answer:** B. Arrhenoblastoma
