Under-secretion of adrenal cortex causes

Options

A. Addison's disease
B. Cretinism
C. Dwarfism
D. Sterility

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the consequences of under-secretion (hyposecretion) of the adrenal cortex.

2. **Identifying the Adrenal Cortex Function**: The adrenal cortex is responsible for producing steroid hormones, primarily cortisol and aldosterone.

3. **Exploring the Options**:
- **Option A: Addison's Disease**: This condition is directly linked to the hyposecretion of adrenal cortex hormones (cortisol and aldosterone). It leads to various symptoms such as fatigue, weight loss, and low blood pressure.
- **Option B: Cretinism**: This condition is caused by the hyposecretion of thyroid hormones, not adrenal hormones. Therefore, it is not related to the adrenal cortex.
- **Option C: Dwarfism**: This condition is associated with the hyposecretion of growth hormone, which is produced by the pituitary gland, not the adrenal cortex.
- **Option D: Sterility**: Sterility can result from various hormonal imbalances, but it is not specifically caused by the under-secretion of adrenal cortex hormones.

4. **Conclusion**: Based on the analysis of the options, the correct answer is **Addison's Disease**, which is caused by the under-secretion of hormones from the adrenal cortex.

### Final Answer:
Under-secretion of the adrenal cortex causes **Addison's Disease**.
