Acrosome formation in spermatogenesis occurs in which stage ?

Options

A. First meiotic division
B. Second meiotic division
C. Growth phase
D. Spermiogenesis

Answer

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis is the process by which sperm cells are produced in males. It involves several stages, including the growth phase, meiotic divisions, and spermiogenesis.

2. **Identifying the Stages**: The stages of spermatogenesis include:
- Growth phase: where spermatogonia develop into primary spermatocytes.
- First meiotic division: where primary spermatocytes divide to form secondary spermatocytes.
- Second meiotic division: where secondary spermatocytes divide to form spermatids.
- Spermiogenesis: the final stage where spermatids mature into spermatozoa.

3. **Focus on Acrosome Formation**: The acrosome is a cap-like structure that develops over the head of the sperm and is crucial for fertilization. The formation of the acrosome occurs during the maturation of spermatids.

4. **Identifying the Correct Stage**: Acrosome formation specifically occurs during the stage known as spermiogenesis. This is when the spermatids undergo morphological changes, including the development of the acrosome and tail.

5. **Conclusion**: Therefore, the correct answer to the question "Acrosome formation in spermatogenesis occurs in which stage?" is **spermiogenesis**.
