 Well, this topic, there is a comparison between spermetogenesis and uogenesis, because we have studied spermetogenesis and uogenesis, these two topics. Now we will be comparing these two very important processes which occur in the gonads, that is spermetogenesis in the testes and uogenesis in the ovaries. So, spermetogenesis, as we have abbreviated it from SMG, so this is the production of sperm from the spermetogonia. So, spermetogonia, if we remember it, the spermetogonia, they undergo the process of myosis, first myodendrobium, the second myodendrobium, or second myodendrobium endicubus sperms or spermatids, which transform into the dense sperms. So, whereas uogenesis is the production of eggs from the uogenia, uogenia, these are the primordial germ cells, jaha se which undergo the process of the myosis. So, next is these spermetogenesis that occurs inside the testes and male, whereas the uogenesis that occurs in the ovaries. In spermetogenesis, all stages occur inside the testes, whereas in uogenesis, all stages accept the last stage that occurs inside the ovaries, that is, except all occur in the inside the ovaries. So, spermetogenesis is a continuous process occurring after puberty till death. Whereas, because sperm formation in human males, so in uogenesis, early stages occur during fetal life, then there is before birth of the female child, and the rest of the process that occurs after puberty till menopause, that is the cessation of the of the reproductive cycle. The fifth point is the sperms developed from the germinal epithelial lining of the seminiferous tribules. Seminiferous tribules, these are the very convoluted tribules, which are present in the testes. Or, we, wall, actually may, which shuruki stages, you have mitosis key, or baqya stages, you have, myosis. So, the eggs develop from germinal epithelium, which can, which overlays the ovaries, because outermost, that is the tunic albuginia, and next layer is the germinal, so all these spermetogonias divide by myosis, producing four sperm cells from each. Whereas, some of the oogonia divide by myosis, producing one egg. So, in this, there is oogenesis, in which one oogonium becomes one egg, and if there is myosis, but the egg ultimately becomes one, because baqya is called polar bodies, which disintegrate, they play no role in reproduction. Now, this is a comparison, diagrammatically shown, this is the spermetogenesis, permetogonium, which is deployed, this primary spermetocyte will be by the process of mitosis, this mitosis is happening, and in this, haploid cells are becoming, engineering, secondary spermetocytes are called, and then after that, spermatids are formed, these spermatids are then metamorphosed, so then spermetozoa or sperms are formed, and we are seeing that from one cell, there are four, there are four sperms are formed. Whereas, oogenesis, oogonium, first of all it will be the primary oocyte, which will be made by mitosis, after that first, myotic, the deviant, it will be the secondary oocyte, and in this, this is the secondary oocyte, and this is the other, the smaller cells, this is the polar body, and after that, second myotic phase, in which the cell will then be unequally divided, or two polar bodies are formed, and then there is present this one applied secondary oocyte. Now the seventh point is, that is in spermetogenesis, growth phase is too short, and whereas in oogenesis, growth phase is very long, then on the primary spermetocyte divided by mitosis, biosis one forming two secondary spermetocytes, whereas the primary spermet oocyte, oocyte divided by myosis, one forming, forming one secondary oocyte, and one polar body, which we have seen in the diagram, or in spermetogenesis, that is the motile gametes are formed, that is sperms, they are motile, and they have a tail, in which they wriggle, move, and after that, in oogenesis, there is the egg which is formed, that is non-motile, it cannot move by its own, if it is transported from the ovary down into the uterus, and then out, then this is brought about by the muscular movement of the uterine cube, and this is how they move, whereas they cannot move by their own, they cannot, they don't have any locomotory as the structures on itself, so this is the comparison between these spermetogenesis and oogenesis.
