This article covers both oogenesis and spermatogenesis. Spermatogenesis In the Beginning Males start producing sperm when they reach puberty, which is usually from10-16 years old. Biological males continually produce sperm in large quantities (~200 million a day). This maximises the likelihood of spe...
10. Can spermatogenesis and oogenesis occur in the same organism? No, spermatogenesis occurs in males, while oogenesis occurs in females in sexually reproducing species.
