The 1-3 coiled structures present within the testicular lobules are

Options

A. responsible for the transportation of gametes .
B. responsible for the formation of androgens.
C. the site where sperms are produced
D. the site where defective sperms are destroyed.

Answer

To solve the question regarding the coiled structures present within the testicular lobules, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures in Testicular Lobules**:
- The testicular lobules contain structures that are essential for sperm production.

2. **Understand the Function of These Structures**:
- The primary function of the coiled structures in the testicular lobules is to produce sperm.

3. **Recognize the Name of These Structures**:
- The coiled structures are known as **seminiferous tubules**.

4. **Evaluate the Options Provided**:
- **Option A**: Responsible for transportation of gametes - This is incorrect as the seminiferous tubules are not primarily for transportation.
- **Option B**: Responsible for formation of androgen - This is also incorrect since androgens are produced by interstitial cells (Leydig cells) and not specifically by the seminiferous tubules.
- **Option C**: Site where sperms are produced - This is correct as the seminiferous tubules are indeed the sites of sperm production.
- **Option D**: Site where defective sperms are destroyed - This is misleading; defective sperm do not have a specific site for destruction within the testes.

5. **Select the Correct Option**:
- Based on the evaluation, the correct answer is **Option C: Site where sperms are produced**.

### Final Answer:
The 1-3 coiled structures present within the testicular lobules are **seminiferous tubules**, which are the sites where sperm are produced.
