In spermatogenesis

a primary spermatocyte produces four similar sperms while in oogenesis a primary oocyte forms

Four similar ova

Three large ova and one polar body

Two large ova and two olar bodies

The difference between ooganesis and spermatogenesis is

oogenesis begins at puberty and spermatogenesis during embryonic development .

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

the Cytoplasmic division is unequal in oogenesis and equal in spermatogenesis .

spermatogenesis is not completed until after fertilization occurs, but oogenesis is completed at the time of birth.

Spermatogenesis changes

Spermatogonium into primary spermatocyte

Primary spermatocyte into secondary spermatocyte

Secondary spermatocyte into spermatid

All the above.
