What is the final stage of sperm maturation known as ?

Options

A. Capacitation
B. Fertilization
C. Spermiation
D. Coagulation

Answer

To answer the question "What is the final stage of sperm maturation known as?" we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sperm Maturation**:
- Sperm maturation involves several stages that sperm cells go through to become capable of fertilizing an egg.

2. **Identifying the Final Stage**:
- The question asks specifically for the final stage of this maturation process. The options given are capacitation, fertilization, spermiation, and coagulation.

3. **Defining Each Term**:
- **Capacitation**: This is the process that sperm undergo after ejaculation, which is essential for fertilization. It prepares the sperm to penetrate and fertilize the egg.
- **Fertilization**: This is the process where the sperm and egg fuse to form a zygote, but it is not a maturation stage.
- **Spermiation**: This refers to the release of mature sperm from Sertoli cells, which is a part of the maturation process but not the final stage.
- **Coagulation**: This refers to the process where the semen thickens after ejaculation, which is not related to the maturation of sperm.

4. **Conclusion**:
- Based on the definitions, the final stage of sperm maturation is **capacitation**. This process is crucial for the sperm to be able to fertilize the ovum.

### Final Answer:
The final stage of sperm maturation is known as **capacitation**.
