Spermatogenesis is the formation of what?

• A. Egg production
• B. Ovary function
• C. Formation of sperm
• D. Development of embryos

Answer: (C)

Spermatogenesis is the formation of sperm cells. In the testes, germ cells begin by dividing to maintain a pool of precursors, then undergo meiosis to reduce the chromosome number and produce haploid sperm. After meiosis, a final differentiation step called spermiogenesis shapes the developing cells into mature, motile sperm with a distinct head, midpiece, and tail. This process creates male gametes ready for fertilization, each carrying a single set of chromosomes (23 in humans). It’s different from egg production, which is oogenesis in females, from ovary function, or from embryo development, which occurs after fertilization to form an embryo.
