Which of the following cells are present in mammalian testes and help to nourish sperms

Options

A. Leydig cells
B. Oxyntic cells
C. Interstitial cells
D. Sertoli cells

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which cells in the mammalian testes are responsible for nourishing sperm.

2. **Identifying the Relevant Cells**: In the mammalian testes, there are two main types of cells involved in sperm production and nourishment:
- **Sertoli Cells**: These cells are located within the seminiferous tubules of the testes and are crucial for the nourishment and support of developing sperm cells.
- **Interstitial Cells (Leydig Cells)**: These cells are found in the spaces between the seminiferous tubules and are responsible for producing testosterone and other androgens, which are important for sperm development but do not directly nourish sperm.

3. **Analyzing the Options**: Based on the information, we need to identify which of the provided options include Sertoli cells, as they are the primary cells that provide nourishment to sperm.

4. **Conclusion**: The correct answer to the question is that Sertoli cells are the cells present in mammalian testes that help to nourish sperm.

**Final Answer**: Sertoli cells are the cells present in mammalian testes that help to nourish sperm.
