With the disintegration of corpus luteum, a decrease in the secretion of____hormone occurs.

Options

A. LH
B. Progesterone
C. LTH
D. FSH

Answer

To solve the question regarding the hormone whose secretion decreases with the disintegration of the corpus luteum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Corpus Luteum**:
- The corpus luteum is a structure that forms in the ovary after ovulation. It is responsible for producing hormones, primarily progesterone, which is crucial for maintaining the uterine lining for a potential pregnancy.

2. **Identify the Hormones Involved**:
- The key hormones to consider in this context are Luteinizing Hormone (LH), Progesterone, Prolactin (LTH), and Follicle-Stimulating Hormone (FSH).

3. **Link Between LH and Corpus Luteum**:
- Luteinizing Hormone (LH) is essential for the maintenance of the corpus luteum. It stimulates the corpus luteum to produce progesterone.

4. **Consequences of Corpus Luteum Disintegration**:
- When the corpus luteum disintegrates (or degenerates), it stops producing progesterone. This disintegration is often triggered by a decrease in LH levels.

5. **Conclusion**:
- Therefore, with the disintegration of the corpus luteum, there is a decrease in the secretion of Luteinizing Hormone (LH).

### Final Answer:
The correct answer is **LH (Luteinizing Hormone)**.
