Leydig cells secrete A under the influence of B which is secreted by C . Choose the option which gives the correct answer for blanks in above statement

Options

A. A- Estrogen B- FSH C - Poslenor pituitary
B. A - Androgen B - Testosterone C - Interstitial cells
C. A - Testosterone B - LH C - Anterior pituitary
D. A - Androgen B - LH C - Seminiferous tubules

Answer

To solve the question, we need to fill in the blanks in the statement: "Leydig cells secrete A under the influence of B which is secreted by C."

### Step-by-Step Solution:

1. **Identify Leydig Cells**: Leydig cells, also known as interstitial cells, are located adjacent to the seminiferous tubules in the testes. Their primary function is to produce hormones, particularly androgens.

**Hint**: Remember that Leydig cells are crucial for male hormone production.

2. **Determine What Leydig Cells Secrete (A)**: The main hormone secreted by Leydig cells is testosterone, which is the principal male sex hormone.

**Hint**: Think about the primary male hormone produced in the testes.

3. **Identify the Influence on Leydig Cells (B)**: Leydig cells are stimulated by luteinizing hormone (LH). This hormone is essential for the regulation of testosterone production.

**Hint**: Recall the hormone that stimulates testosterone production in males.

4. **Identify the Source of the Stimulating Hormone (C)**: Luteinizing hormone (LH) is secreted by the anterior pituitary gland. The anterior pituitary releases LH in response to signals from the hypothalamus.

**Hint**: Consider where LH is produced in the body.

5. **Fill in the Blanks**:
- A = Testosterone
- B = Luteinizing hormone (LH)
- C = Anterior pituitary

Thus, the completed statement is: "Leydig cells secrete testosterone under the influence of luteinizing hormone (LH) which is secreted by the anterior pituitary."

### Final Answer:
- A = Testosterone
- B = Luteinizing hormone (LH)
- C = Anterior pituitary

### Correct Option:
- The correct option that matches this information is option 3.
