Spermatogenesis vs. Oogenesis
Begins at puberty:
- Spermatogenesis begins at puberty in males when the production of sperm cells starts.
- Oogenesis, on the other hand, begins during fetal development in females.
All spermatogonia develop into primary spermatocytes which undergoes meiosis at puberty:
- In spermatogenesis, all spermatogonia develop into primary spermatocytes, which undergo meiosis to produce spermatids.
- In oogenesis, only one out of several oogonia develops into a mature ovum, while the others degenerate.
One germ cell gives rise to 4 gametes:
- During spermatogenesis, one germ cell undergoes meiosis to produce four functional sperm cells.
- In oogenesis, one germ cell produces one mature ovum and three polar bodies, which are not functional gametes.
Equal nuclear and cytoplasmic division during meiosis:
- In spermatogenesis, meiosis results in the formation of four equal-sized spermatids with both nuclear and cytoplasmic components.
- In oogenesis, there is unequal division of cytoplasm during meiosis, resulting in one large ovum with most of the cytoplasm and three smaller polar bodies with minimal cytoplasm.
Therefore, the statement "All spermatogonia develop into primary spermatocytes which undergoes meiosis at puberty" is incorrect as only a fraction of spermatogonia develop into primary spermatocytes during spermatogenesis.

Some spermatogonia periodically develop into primary spermatocytes which undergoes meiosis.
