**Introduction:**

Reproductive processes in animals are fundamental for the continuation of species. Gametogenesis, spermatogenesis, folliculogenesis, ovulation, transport and survival of gametes, and fertilization are crucial events in the reproductive cycle of animals. Understanding these processes is essential for reproductive success and the production of offspring. This comprehensive study aims to delve deep into the reproductive processes in animals and provide insights into the mechanisms involved in each stage.
