Which of the following controls spermatogenesis:

Options

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

Answer

**Step-by-Step Text Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis is the process of sperm cell development, which occurs in the testes. It is regulated by various hormones.

2. **Identifying Key Hormones**: The question provides four options: FSH (Follicle Stimulating Hormone), LTH (Luteotropic Hormone), LH (Luteinizing Hormone), and Vasopressin.

3. **Role of FSH**: FSH is known to stimulate the Sertoli cells in the testes, which are crucial for the nourishment and development of sperm cells. Therefore, FSH plays a significant role in regulating spermatogenesis.

4. **Role of LH**: LH stimulates the Leydig cells in the testes to produce testosterone, which is also important for spermatogenesis but does not directly control the process.

5. **Role of LTH**: LTH, or prolactin, primarily regulates milk production in females and does not have a direct role in spermatogenesis.

6. **Role of Vasopressin**: Vasopressin, also known as antidiuretic hormone (ADH), is involved in water retention in the kidneys and does not play a role in spermatogenesis.

7. **Conclusion**: Based on the functions of these hormones, FSH is the primary hormone that controls spermatogenesis in males.

**Final Answer**: FSH Hormone controls spermatogenesis.
