Testosterone is produced by

Options

A. Aciner cells
B. Sertoli cells
C. Epithelial cell
D. Leydig cells

Answer

**Step-by-Step Solution:**

1. **Understanding Testosterone**: Testosterone is identified as a steroid hormone and is primarily known as the male hormone.

2. **Identifying the Source**: The primary reproductive organ in males is the testis, which is responsible for the production of male gametes (sperm).

3. **Structure of the Testis**: Each testis contains numerous compartments known as testicular lobules. There are approximately 250 testicular lobules in one testis.

4. **Components of Testicular Lobules**: Within each testicular lobule, there are highly coiled structures called seminiferous tubules.

5. **Interstitial Space**: In the cross-section of the seminiferous tubule, there is an interstitial space that contains specific cells.

6. **Identifying the Cells**: The cells located in the interstitial space are known as interstitial cells or Leydig cells.

7. **Function of Leydig Cells**: Leydig cells are responsible for producing hormones, particularly a group known as androgens.

8. **Production of Testosterone**: Among the androgens produced by Leydig cells, testosterone is the primary hormone.

9. **Conclusion**: Therefore, testosterone is produced by the Leydig cells in the testis.

**Final Answer**: Testosterone is produced by Leydig cells (interstitial cells) in the testis.
