How the FSH controls the spermatogenesis ?

Options

A. By releasing testosterone
B. By activation of spermatogonia
C. By promoting the Sertoli cells to release the ABP
D. By promoting the Sertoli cells to release testosterone

Answer

### Step-by-Step Solution:

1. **Understanding Spermatogenesis**:
- Spermatogenesis is the process of sperm production in the male reproductive system. It occurs in the seminiferous tubules of the testes.

2. **Role of FSH**:
- Follicle Stimulating Hormone (FSH) is a hormone produced by the anterior pituitary gland. It plays a crucial role in regulating reproductive processes.

3. **FSH and Sertoli Cells**:
- FSH specifically acts on Sertoli cells, which are supportive cells located in the seminiferous tubules. These cells are essential for the nourishment and development of sperm cells.

4. **Release of Androgen Binding Protein (ABP)**:
- When FSH binds to its receptors on Sertoli cells, it stimulates these cells to produce and release Androgen Binding Protein (ABP).
- ABP binds to testosterone, which is necessary for the maturation of sperm cells.

5. **Conclusion**:
- Therefore, FSH controls spermatogenesis primarily by promoting Sertoli cells to release ABP, which aids in the effective functioning of testosterone in the process of sperm production.

6. **Final Answer**:
- The correct answer to the question is that FSH controls spermatogenesis by promoting the Sertoli cells to release ABP.
