The function of Sertoli cells is controlled by :

Options

A. Estrogen
B. FSH
C. Testosterone
D. LH

Answer

To solve the question regarding the control of Sertoli cells, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Sertoli Cells**:
- Sertoli cells are specialized nurse cells located in the seminiferous tubules of the testes. Their primary role is to support and nourish developing sperm cells during the process of spermatogenesis.

2. **Identifying the Hormones**:
- The question provides four options: Estrogen, FSH (Follicle Stimulating Hormone), Testosterone, and LH (Luteinizing Hormone). We need to determine which hormone is responsible for controlling the function of Sertoli cells.

3. **Role of FSH**:
- Follicle Stimulating Hormone (FSH) is known to stimulate the Sertoli cells. It plays a crucial role in the regulation of spermatogenesis by promoting the development and function of these cells.

4. **Evaluating Other Hormones**:
- **Estrogen**: While it plays a role in the reproductive system, it is not primarily responsible for the function of Sertoli cells.
- **Testosterone**: This hormone is important for the development of male secondary sexual characteristics and also influences spermatogenesis, but it does not directly control Sertoli cell function.
- **LH**: Luteinizing Hormone primarily stimulates Leydig cells to produce testosterone, not Sertoli cells.

5. **Conclusion**:
- Based on the information, the hormone that controls the function of Sertoli cells is FSH. Therefore, the correct answer is **B. FSH**.

### Final Answer:
The function of Sertoli cells is controlled by **B. FSH (Follicle Stimulating Hormone)**.
