The release of spermatozoa from the Sertoli cells is called as :

Options

A. spermiation
B. spermiogenesis
C. emission
D. ejaculation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the release of spermatozoa from Sertoli cells. Sertoli cells are supportive cells found in the seminiferous tubules of the testes, crucial for sperm development.

2. **Identifying Relevant Terms**:
- **Spermiation**: This is the process where mature spermatozoa are released from the Sertoli cells into the lumen of the seminiferous tubules.
- **Spermiogenesis**: This refers to the transformation of spermatids into spermatozoa through morphological changes, but it does not involve their release from Sertoli cells.
- **Emission**: This is the process of ejaculation, where sperm and seminal fluid are expelled from the male body, but it is not the release from Sertoli cells.
- **Ejaculation**: This is the act of discharging sperm and seminal plasma during sexual intercourse.

3. **Conclusion**: Based on the definitions, the correct term for the release of spermatozoa from Sertoli cells is **Spermiation**.

4. **Final Answer**: The release of spermatozoa from the Sertoli cells is called **Spermiation**.
