Eunuchoidism is due to

Options

A. Perturbation of estrogen to androgen ratio
B. Failure of testosterone secretion
C. Tumor in testis
D. Tumor in ovaries

Answer

**Step-by-Step Solution:**

1. **Understanding Eunuchoidism**: Eunuchoidism is a condition characterized by the inadequate production of male sex hormones, particularly testosterone, by the testes. This results in a lack of development of secondary male sexual characteristics.

2. **Identifying the Causes**: The question asks about the cause of eunuchoidism. We need to analyze the provided options to determine which one correctly identifies the underlying issue.

3. **Evaluating the Options**:
- **Option 1**: Perturbation of estrogen to androgen ratio. This is not the primary cause of eunuchoidism since the condition is specifically related to testosterone production.
- **Option 2**: Failure of testosterone secretion. This directly correlates with eunuchoidism, as the condition arises from insufficient testosterone production by the testes.
- **Option 3**: Tumor in testes. While a tumor could potentially lead to reduced testosterone production, it is not the defining cause of eunuchoidism itself.
- **Option 4**: Tumor in ovaries. This option is irrelevant to eunuchoidism, as it pertains to female reproductive organs and does not affect male hormone production.

4. **Conclusion**: After evaluating all the options, the most accurate cause of eunuchoidism is the failure of testosterone secretion from the testes.

5. **Final Answer**: The correct answer is **Option 2: Failure of testosterone secretion**.
