Difference Between Spermatogenesis and Oogenesis

Difference Between Spermatogenesis And Oogenesis

By a process, known as gametogenesis, the testis in a male and ovary in a female, produce gametes, i.e, sperms and ovum respectively. The gametogenesis responsible for the production of the sperm is known as spermatogenesis and that responsible for the production of the ovum is known as oogenesis. In this article, let us look at the difference between spermatogenesis and oogenesis. In the tabular column listed below, the differences between spermatogenesis and oogenesis are given.

Spermatogenesis vs Oogenesis

Spermatogenesis Oogenesis
The production of sperms from spermatogonia is known as spermatogenesis The production of eggs from oogonia is known as oogenesis
Occurs in testes Occurs inside the ovary
All stages are completed in testes The major part of oogenesis occurs inside the ovary. The last few stages occur in the oviduct.
It is a continuous process It is a discontinuous process. The early stages take place in the foetus and the rest in later stages of life.
Produces motile gametes Produces non-motile gametes
Equal cytokinesis occurs during the spermatogenesis producing four sperms Unequal cytokinesis occurs during oogenesis ultimately producing one ovum and four polar bodies

Spermatogenesis and oogenesis refer to the production of sperm and ovum respectively. The main difference between the two is their occurrence in different sexes of organisms. To learn more differences like the difference between haploid and diploid, Visit BYJU’S.
