Answer 2

Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo.

Let us have a detailed look at the difference between spermatogenesis and oogenesis.

Spermatogenesis vs Oogenesis
The difference between spermatogenesis and oogenesis are given below:

Difference Between Spermatogenesis And 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
