Leydig cells are found in

Options

A. testis
B. ovary
C. vasa deferens
D. All of these

Answer

**Step-by-Step Solution:**

1. **Identify Leydig Cells:** Leydig cells, also known as interstitial cells, are specialized cells in the male reproductive system.

2. **Locate the Primary Reproductive Organ:** The primary reproductive organ in males is the testes.

3. **Understand the Structure of Testes:** The testes are oval-shaped and contain several compartments known as testicular lobules. Each testis has around 250 of these lobules.

4. **Examine the Testicular Lobules:** Inside each testicular lobule, there are 1 to 3 highly coiled structures called seminiferous tubules, which are responsible for sperm production.

5. **Identify the Interstitial Spaces:** Between the seminiferous tubules, there are interstitial spaces. This is where Leydig cells are located.

6. **Function of Leydig Cells:** Leydig cells secrete male hormones, primarily testosterone, which plays a crucial role in male reproductive functions.

7. **Conclusion:** Therefore, Leydig cells are found in the interstitial spaces of the testes.

**Final Answer:** Leydig cells are found in the testes.
