Stage of sperm before entry into ovum/s prefertilisation process is

Options

A. Maturation
B. Insemination
C. Capacitation
D. Fertilization.

Answer

To answer the question regarding the stage of sperm before entry into the ovum during the pre-fertilization process, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Options**: The options given are maturation, insemination, capacitation, and fertilization. We need to identify which of these stages occurs right before the sperm enters the ovum.

2. **Define Each Term**:
- **Maturation**: This refers to the overall development of sperm, which occurs in the male reproductive system.
- **Insemination**: This is the process of depositing sperm into the female reproductive tract.
- **Capacitation**: This is a specific physiological change that sperm undergo after insemination, which prepares them for fertilization.
- **Fertilization**: This is the actual fusion of the sperm and ovum.

3. **Identify the Relevant Stage**: The question specifically asks for the stage before the sperm enters the ovum. Capacitation is a critical process that occurs after insemination and before fertilization, enabling the sperm to penetrate the ovum.

4. **Conclusion**: Based on the definitions and understanding of the processes, the correct answer is **capacitation**. This stage involves biochemical changes that prepare the sperm for successful fertilization.

### Final Answer:
The stage of sperm before entry into the ovum during the pre-fertilization process is **capacitation**.
