An Intiative by Sri Chaitanya

Oogenesis begins at puberty and spermatogenesis during embryonic development.

Oogenesis results in formation of four haploid ova from a primary oocyte, while during spermatogenesis only one sperm is formed from a primary spermatocyte.

Spermatogenesis is not completed until after fertilisation occurs, but oogenesis is completed at the time of birth.

The cytoplasmic division is unequal in oogenesis and equal in spermatogenesis.

Detailed Solution

The difference between oogenesis and spermatogenesis is that the cytoplasmic division is unequal in oogenesis and equal in spermatogenesis.

Spermatogenesis begins at puberty. Four spermatozoa are formed from one primary spermatocyte.

Oogenesis begins during the embryonic development and is complete only after the entry of sperm during the fertilisation. Only one ovum is formed from each primary oocyte.
