What types of cell division occur during gametogenesis? What is the difference between spermatogenesis and oogenesis?

With gametogenesis; spermatogenesis and ovogenesis.
The first difference between spermatogenesis and oogenesis is the fact that in addition to the stage of reproduction, maturation, growth, there is a fourth one – formation. It is during this period that the formation of an apparatus for movement occurs in male sex cells, as a result of which they acquire an elongated shape, which makes their movement easier.
The second distinguishing feature can be called the feature that, at the stage of division, 4 germ cells are obtained immediately from a spermatocyte of the first order, and only one female germ cell is formed from a first-order oocyte, ready for fertilization.
