Name the hormone which stimulates the synthesis and secretion of androgens from testis.

Answer

To answer the question "Name the hormone which stimulates the synthesis and secretion of androgens from testis," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Role of Hormones in the Testis**:
- The testis is influenced by hormones known as gonadotropins, which play a crucial role in male reproductive functions.

2. **Differentiate Between Gonadotropins**:
- There are two main types of gonadotropins: Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH).
- Both hormones are released by the anterior pituitary gland and are regulated by the hypothalamus.

3. **Function of Luteinizing Hormone (LH)**:
- Luteinizing Hormone specifically stimulates the testis to synthesize and secrete androgens, primarily testosterone.
- Testosterone is the main androgen produced in males and is essential for various male reproductive functions.

4. **Function of Follicle Stimulating Hormone (FSH)**:
- Follicle Stimulating Hormone primarily aids in spermatogenesis, which is the process of sperm production in the testis.

5. **Conclusion**:
- Since the question specifically asks for the hormone that stimulates the synthesis and secretion of androgens, the correct answer is **Luteinizing Hormone (LH)**.

### Final Answer:
The hormone that stimulates the synthesis and secretion of androgens from the testis is **Luteinizing Hormone (LH)**.
