Which one of the following pairs correctly matches a hormone with a disease resulting from its deficiency?

Options

A. 1)Lutenizing hormone-Failure of ovulation
B. 2)Insulin-Diabetes insipidus
C. 3)Thyroxine-Tetany
D. 4)Parathyroid hormone-Diabetes mellitus

Answer

To solve the question of matching a hormone with a disease resulting from its deficiency, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Hormones and Diseases in Each Option**:
- Option 1: Deuterizing hormone (LH) with failure of ovulation.
- Option 2: Insulin with diabetes insipidus.
- Option 3: Thyroxine with tetany.
- Option 4: Parathyroid hormone with diabetes mellitus.

2. **Evaluate Option 1**:
- Deuterizing hormone (Luteinizing Hormone, LH) is indeed involved in the ovulation process. A deficiency in LH can lead to failure of ovulation.
- **Conclusion**: This option is correct.

3. **Evaluate Option 2**:
- Insulin is produced by the pancreas and is responsible for regulating blood glucose levels. Diabetes insipidus, however, is caused by a deficiency of vasopressin (ADH), which is not related to insulin.
- **Conclusion**: This option is incorrect.

4. **Evaluate Option 3**:
- Thyroxine is a hormone produced by the thyroid gland, and tetany is caused by a deficiency of parathyroid hormone (PTH), not thyroxine.
- **Conclusion**: This option is incorrect.

5. **Evaluate Option 4**:
- Parathyroid hormone (PTH) regulates calcium levels in the blood. Diabetes mellitus is caused by a deficiency of insulin, not PTH.
- **Conclusion**: This option is incorrect.

6. **Final Conclusion**:
- The only correct match is Option 1: Deuterizing hormone (LH) with failure of ovulation.

### Final Answer:
The correct pair that matches a hormone with a disease resulting from its deficiency is **Option 1: Deuterizing hormone (LH) with failure of ovulation**.
