The development of spermatozoa is called:

The development of spermatozoa is called:

• A. Oogenesis
• B. Spermatogenesis
• C. Embryogenesis
• D. Cytokinesis

Answer: (B)

Spermatogenesis is the process by which spermatozoa are produced in the testes. It starts with spermatogonia undergoing mitotic divisions to maintain the stem cell pool, then proceeds through meiosis to create haploid spermatids, and finally spermiogenesis, where these spermatids are transformed into mature sperm. This entire sequence occurs in the seminiferous tubules and begins at puberty, continuing throughout life. Oogenesis refers to egg production in the ovaries, embryogenesis is the development of the embryo after fertilization, and cytokinesis is the cytoplasmic division that occurs during cell division, not the production of sperm.
