As compared to the other cells in a mammalian testis, Leydig cells will have more amount of

Options

A. Rough Endoplasmic Reticulum
B. Golgi complex
C. Smooth Endoplasmic Reticulum
D. Lysosomes

Answer

To solve the question regarding Leydig cells in the mammalian testis, we need to analyze the options provided and understand the characteristics of Leydig cells.

### Step-by-Step Solution:

1. **Understanding Leydig Cells**: Leydig cells, also known as interstitial cells, are located in the testes and are primarily responsible for the production of testosterone, a key male sex hormone.

2. **Analyzing the Options**:
- **Option 1: Rough Endoplasmic Reticulum (RER)**: The RER is involved in the synthesis of proteins. Leydig cells do not primarily focus on protein synthesis, so this option is unlikely to be correct.
- **Option 2: Golgi Complex**: The Golgi apparatus is responsible for sorting and packaging proteins. While Leydig cells may have some Golgi apparatus for processing, it is not the most prominent feature compared to other cell types.
- **Option 3: Smooth Endoplasmic Reticulum (SER)**: The SER is involved in the synthesis of lipids and steroid hormones. Since Leydig cells produce testosterone, they would have a high amount of smooth endoplasmic reticulum to facilitate this process. This option is likely correct.
- **Option 4: Lysosomes**: Lysosomes are involved in the breakdown of waste materials and cellular debris. They are not specifically abundant in Leydig cells, making this option incorrect.

3. **Conclusion**: Based on the analysis, Leydig cells have a higher amount of smooth endoplasmic reticulum compared to other cells in the mammalian testis. Therefore, the correct answer is **Option 3: Smooth Endoplasmic Reticulum**.
