Difference between spermatogenesis and oogenesis, Biology
























It take place in testis


It take place whole life


In maturation phase many series of spermatogonia & residual spermatogonia are formed


Growth phase take place short period


Less growth during growth phase


No any division in growth phase


In growth phase primary spermatocyte formed


During maturation phase 4 spermatid formed


In this meiosis first then differentiation


sperms are motile

in ovary


45 to 50 years


Oogonia, accessory nurse cell & follicle cells are formed



long period


More growth during growth phsae


Meiosis start in growth phase up to diplotene stage


Primary oocyte formed


1 ovum and 3 polar bodies are formed


In this differentiation first then meiosis


Ova is immotile.
