Question

How do spermatogenesis and oogenesis differ in terms of the number of gametes they produce?

Answer 1

Hint: Spermatogenesis and oogenesis are known as the processes of formation of male and female gametes. Spermatogenesis leads to the formation of the male's sperms, whereas oogenesis helps in the formation of female's ova. The fertilization of sperm and ova leads to the formation of the zygote that further develops into an embryo.

Complete answer:

Spermatogenesis	Oogenesis
1. The production of sperms from spermatogonia is known as spermatogenesis which Occurs in testes.	1. The production of eggs from oogonia is known as oogenesis and it occurs inside the ovary.
2. All stages are completed in testes. It is a continuous process.	2. The major steps of oogenesis occur inside the ovary The last left stages occur in the oviduct. It is a discontinuous process asThe early stages take place in the foetus and the rest in later stages of life.
3. Produces motile gametes and Equal cytokinesis occurs during the spermatogenesis producing exact four sperms.	3. Produces non-motile gametes and Unequal cytokinesis occurs during oogenesis ultimately producing one ovum and exactly four polar bodies.

It can be concluded that every cycle of spermatogenesis produces around 4 spermatozoa whereas every cycle of oogenesis can only produce one ovum at a particular time hence sperm production is in large quantities whereas Ovum are produced only once every month during the menstrual cycle, every ovum gets mature and wait for the sperm to get fertilized if that doesn't happen it comes out during menses.

Note: Sperm formation in males starts at puberty and keeps on forming for a lifetime whereas, in females, the ovum is present in the premature form(oogonium) from the birth and starts getting mature when they first hit puberty or say the first menstrual cycle.
