What is spermatogenesis?

• A. Formation of eggs
• B. Formation of sperm
• C. Maturation of ova
• D. Process of fertilization

Answer: (B)

Spermatogenesis is the process by which male gametes are produced. It takes place in the seminiferous tubules of the testes and begins at puberty. The sequence involves the mitotic division of spermatogonial stem cells to maintain supply, followed by meiosis I and II to create haploid sperm, and a final maturation step called spermiogenesis that turns round spermatids into mature sperm cells. The end product is sperm carrying 23 chromosomes. This is distinct from formation of eggs, which is oogenesis, and from fertilization, which is the fusion of sperm and egg.
