Production of sperms from spermatids is

Options

A. Spermiogenesis
B. Spermatogenesis does not occur
C. Oogenesis
D. Gametogenesis.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the process involved in the production of sperm from spermatids.

2. **Identifying the Correct Term**: The process of transforming spermatids into mature sperm is specifically called **spermiogenesis**.

3. **Distinguishing Related Terms**: It's important to differentiate between related terms:
- **Spermatogenesis**: This is the overall process of sperm production, which includes several stages: spermatogonia (stem cells) develop into primary spermatocytes, which then undergo meiosis to form secondary spermatocytes and eventually spermatids.
- **Spermiogenesis**: This is the final stage of spermatogenesis where spermatids undergo transformation into mature spermatozoa (sperm).
- **Oogenesis**: This refers to the formation of ova (egg cells) in females and is not relevant to this question.
- **Gametogenesis**: This is a broader term that encompasses the formation of both sperm and eggs but does not specifically refer to the transformation of spermatids.

4. **Location of the Process**: Spermiogenesis occurs in the **testes**, specifically within the seminiferous tubules where spermatogenesis takes place.

5. **Timing of the Process**: Spermiogenesis begins at **puberty**, marking the onset of male fertility.

6. **Final Transformation**: During spermiogenesis, spermatids undergo a metamorphosis where they develop tails and lose excess cytoplasm, becoming streamlined sperm cells.

7. **Release of Sperm**: After spermiogenesis, the mature sperm are embedded in Sertoli cells and are finally released into the lumen of the seminiferous tubules through a process known as **spermiation**.

### Final Answer:
The production of sperm from spermatids is called **spermiogenesis**.
