**2.3.1 What is spermatogenesis?** Spermatogenesis is the process by which sperm cells are produced in males. It starts with diploid cells in the testes that undergo meiosis to become haploid spermatozoa. --- **2.3.2 Where does spermatogenesis occur in males?** Spermatogenesis takes place in the seminiferous tubules of the testes. --- **2.3.3 Describe oogenesis.** Oogenesis is the process by which egg cells are produced in females. It involves primary oocytes undergoing meiosis to form secondary oocytes and eventually mature ova, which are released during ovulation. --- **Differences Between Gametogenesis in Males and Females** | **Aspect** | **Males** | **Females** | |-------------------|----------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------| | **Cellular Outcome** | Each spermatogonium produces four viable sperm cells. | Each oogonium typically produces one mature ovum and polar bodies. | | **Timing and Continuity** | Continues throughout life in a cyclical process. | Occurs before birth and continues cyclically with prolonged meiotic arrest. |

Spermatogenesis is the process through which male gametes, or sperm cells, are produced. This complex journey begins in the seminiferous tubules of the testes, where diploid spermatogonia undergo cellular division through meiosis. The resulting four haploid sperm cells are then further refined through a transformation process called spermiogenesis, ultimately leading to the production of mature, motile sperm ready for fertilization. Oogenesis is the developmental process that produces female gametes, or ova. This process occurs primarily in the ovaries, starting from a primary oocyte that undergoes meiosis. However, unlike spermatogenesis, only one viable ovum is produced from each round of meiosis, with the other three forming polar bodies that eventually disintegrate. Additionally, oogenesis is a lengthy process, often beginning before birth and completing only upon fertilization. The cyclic nature of oogenesis (think menstrual cycle) adds another fascinating layer to the complexity of female reproduction compared to the continuous production seen in males.
