Which cells synthesise and secrete testicular hormones (androgens) in man?

Options

A. 1.Sertoll cells
B. 2.Mucous cells
C. 3.Spermatogonla
D. 4.Leydig's cells

Explanation

To answer the question "Which cells synthesize and secrete testicular hormones (androgens) in man?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are Sertoli cells, mucus cells, spermatogonia, and Leydig cells.

2. **Understand the Function of Each Cell Type**:
- **Sertoli Cells**: These cells are located in the seminiferous tubules of the testes. Their primary role is to support and nourish developing sperm cells, but they do not secrete hormones.
- **Mucus Cells**: These cells are not typically found in the testes and are primarily involved in secreting mucus in other tissues. They do not play a role in hormone secretion in the testes.
- **Spermatogonia**: These are the germ cells that undergo division to form sperm. They are involved in the process of spermatogenesis but do not secrete hormones.
- **Leydig Cells**: These cells are located in the interstitial spaces between the seminiferous tubules in the testes. They are responsible for synthesizing and secreting androgens, which are the male sex hormones.

3. **Determine the Correct Answer**: Based on the functions of the cell types, Leydig cells are the correct answer as they synthesize and secrete testicular hormones (androgens).

### Final Answer:
The cells that synthesize and secrete testicular hormones (androgens) in man are **Leydig cells**.
