Difference Between Spermatogenesis And Oogenesis. In this article, you will read about what is spermatogenesis, what is oogenesis, what is the main difference between spermatogenesis and oogenesis, and a comparison between them. Although both are totally different from each other, but they serve the same purpose. Both spermatogenesis and oogenesis are the procedure are involved in the formation of male and female gametes.
What Is The Main Difference Between Spermatogenesis And Oogenesis?
The main difference between spermatogenesis and oogenesis is that spermatogenesis is the process of the formation of sperms. On the other hand, oogenesis is the process that helps in the formation of ova. When there is the fertilization of sperm and ova, it forms a zygote. This zygote develops into an embryo.
What Is Spermatogenesis?
Spermatogenesis is the formation of the sperms cells. This process takes place in seminiferous tubules inside the testes. It is the procedure in which a diploid stem called spermatogonium forms the haploid sperm. The spermatogonium consists of 2n chromosomes, that are divided into four haploids (n) spermatozoa. This means that equal cytokinesis occurs, resulting in the formation of four chromosomes.
The process of spermatogenesis occurs, when a male attains puberty. And this process remains to continue for the rest of their life. Millions of sperm are formed in spermatogenesis on daily basis. This whole process takes about 70 days.
What Is Oogenesis?
Oogenesis is the process in which the ovum is formed. This process takes place in the ovaries of a female. In oogenesis, eggs are produced in the ovaries. The ovaries are produced from the oogonia present in the ovaries. The diploid primary oocyte produces the ovum by meiosis.
Unlike spermatogenesis, oogenesis occurs only once a month. It starts from the age of puberty and remains till menopause. In oogenesis, equal cytokinesis occurs one time in a month that produces one large ovum, along with tiny polar bodies.
Comparison Between Spermatogenesis Vs Oogenesis:
-Spermatogenesis is the production of sperms.
-Oogenesis is the production of eggs.
-Sperms are produced by spermatogonia.
-Eggs are formed by oogonia.
-Spermatogenesis occurs in testes.
-Oogenesis occurs in ovaries.
-All the stages of spermatogenesis take place in testes.
-The first stages of oogenesis take place in the ovaries.
-Spermatogenesis is a continuous process.
-Oogenesis is a discontinuous process, which ends in menopause.
-Spermatogenesis produces motile gametes.
-Oogenesis produces non-motile gametes.
-In spermatogenesis, equal cytokinesis forms the 4 haploid sperm.
-In oogenesis, unequal cytokinesis forms only 1 large ovum along with tiny polar bodies.
