Males in which testis fail to descend to the scrotum are generally Infertile due to inhibition of Gametogenesis and this disorder is known as ......... .

Options

A. Anarchoidism
B. Cryptorchidism
C. Gynaecomastia
D. None of these

Explanation

To solve the question regarding the condition in which males have testis that fail to descend to the scrotum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Condition**: The question describes a condition where the testis does not descend into the scrotum in males. This is a medical condition that can affect fertility.

2. **Identifying the Consequences**: When the testis fails to descend, it can lead to infertility. This is primarily due to the inhibition of gametogenesis, which is the process of forming gametes (sperm in males).

3. **Temperature Factor**: The scrotum is located outside the body to maintain a lower temperature, which is crucial for proper sperm development. If the testis remains inside the body, the higher temperature can inhibit gametogenesis.

4. **Terminology**: The medical term for the failure of the testis to descend into the scrotum is known as "Cryptorchidism." This term is derived from Greek, where "crypto" means hidden and "orchid" refers to testis.

5. **Final Answer**: Therefore, the disorder in which males have testis that fail to descend to the scrotum, leading to infertility due to inhibition of gametogenesis, is known as **Cryptorchidism**.
