Sertoli cells are regulated by the pituitary hormone known as –

Options

A. FSH
B. GH
C. Prolactin
D. LH

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which pituitary hormone regulates Sertoli cells.

2. **List the Options**: The options provided are FSH (Follicle Stimulating Hormone), GH (Growth Hormone), Prolactin, and LH (Luteinizing Hormone).

3. **Understand Sertoli Cells**: Sertoli cells are located in the seminiferous tubules of the testes and are crucial for supporting and nourishing developing sperm cells during spermatogenesis.

4. **Review the Functions of the Hormones**:
- **FSH (Follicle Stimulating Hormone)**: Stimulates Sertoli cells to produce substances necessary for sperm maturation, including Androgen Binding Protein (ABP).
- **GH (Growth Hormone)**: Primarily regulates growth and metabolism, not directly involved with Sertoli cells.
- **Prolactin**: Mainly involved in lactation and has no direct role in regulating Sertoli cells.
- **LH (Luteinizing Hormone)**: Primarily stimulates Leydig cells to produce testosterone, not directly affecting Sertoli cells.

5. **Determine the Correct Answer**: Since FSH is known to stimulate Sertoli cells and is essential for spermatogenesis, the correct answer is FSH.

6. **Final Answer**: The pituitary hormone that regulates Sertoli cells is FSH.
