Study Notes
Stages of Spermatogenesis
- Spermatogenesis initiates with spermatogonia, diploid stem cells that differentiate into primary spermatocytes.
- In the development of sperm, there are five key stages: spermatogonium, primary spermatocyte, secondary spermatocyte, spermatids, and mature sperm cells (spermatozoa).
Key Stages of Development
- Spermatogonium: A single diploid cell that undergoes mitosis, producing primary spermatocytes.
- Primary Spermatocyte: A diploid cell that undergoes Meiosis I, resulting in two secondary spermatocytes.
- Secondary Spermatocytes: Two haploid cells that proceed to Meiosis II, producing spermatids.
- Spermatids: Four haploid cells formed from secondary spermatocytes that will undergo spermiogenesis.
Process of Spermiogenesis
- Spermiogenesis is the final transformation phase where spermatids develop into functional sperm cells, acquiring specialized features for motility.
