Study Notes
Gametogenesis
- Gametogenesis is the process by which primary sex organs (testes in males and ovaries in females) produce gametes (sperm and ovum).
- In males, spermatogenesis begins at puberty.
- Spermatogonia, the immature male germ cells, multiply by mitosis, increasing their number.
- Primary spermatocytes are spermatogonia which periodically undergo meiosis.
- A primary spermatocyte divides to form two secondary spermatocytes (a reduction division, reducing chromosome number).
- Secondary spermatocytes undergo a second meiotic division, each forming four spermatids.
- Spermatids mature into spermatozoa (sperms) through spermiogenesis.
- During spermiogenesis, sperm heads become embedded in Sertoli cells before being released from seminiferous tubules (spermiation).
- Each spermatogonium is diploid (46 chromosomes), and spermatids are haploid (23 chromosomes).
- Hormones GnRH, LH, and FSH regulate spermatogenesis.
