This spermatogenesis lecture explains sperm production processes in men. Spermatogenesis is the process of sperm production in male. Spermatogenesis is the process where spermatozoa are comprised of male primordial germ cells via mitosis and meiosis. The initial cells on this pathway are known as spermatogonia, which yield important spermatocytes through mitosis. The main spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte divides into two spermatids via Meiosis II. These transform mature spermatozoa, sometimes called sperm cells. For that reason, the predominant spermatocyte offers rise to 2 cells, the secondary spermatocytes, and the two secondary spermatocytes through their subdivision produce four spermatozoa.
Spermatozoa are the mature male gametes in lots of sexually reproducing organisms. As a result, spermatogenesis is the male variation of gametogenesis. In mammals it occurs within the seminiferous tubules of the male testes in a stepwise fashion. Spermatogenesis is particularly stylish upon most advantageous stipulations for the method to occur safely, and is important for sexual replica. DNA methylation and histone change had been implicated in the legislation of this procedure. It starts at puberty and frequently continues uninterrupted except loss of life, even though a moderate cut down may also be discerned within the quantity of produced sperm with develop in age.

Spermatogenesis is the process by which male primary sperm cells undergo meiosis, and produce a number of cells termed spermatogonia, from which the primary spermatocytes are derived. Each primary spermatocyte divides into two secondary spermatocytes, and each secondary spermatocyte into two spermatids or young spermatozoa. These develop into mature spermatozoa, also known as sperm cells. Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa.
Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis. In mammals it occurs in the male testes and epididymis in a stepwise fashion, and for humans takes approximately 64 days. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. DNA methylation and histone modification have been implicated in the regulation of this process. It starts at puberty and usually continues uninterrupted until death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age. The entire process can be broken up into several distinct stages, each corresponding to a particular type of cell in human:

The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis. The primary spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte then completes meiosis as it divides into two spermatids.

Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. DNA methylation and histone modification have been implicated in the regulation of this process.[2] It starts at puberty and usually continues uninterrupted until death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age (see Male infertility). Oogenesis, ovogenesis or oögenesis /ˌoʊ.əˈdʒɛnɨsɪs/[1] is the creation of an ovum (egg cell). It is the female form of gametogenesis; the male equivalent is spermatogenesis. It involves the development of the various stages of the immature ovum. In mammals, the first part of oogenesis starts in the germinal epithelium, which gives rise to the development of ovarian follicles, the functional unit of the ovary. Note that this process, important to all animal life cycles yet unlike all other instances of cell division, occurs completely without the aid of oo spindle-coordinating centrosomes.[2][3] Oogenesis consists of several sub-processes: oocytogenesis, ootidogenesis, and finally maturation to form an ovum (oogenesis proper). Folliculogenesis is a separate sub-process that accompanies and supports all three oogenetic sub-processes. Source of the article published in description is Wikipedia. I am sharing their material.

This spermatogenesis lecture explains sperm production processes in men. Spermatogenesis is the process of sperm production in male. Spermatogenesis is the process where spermatozoa are comprised of male primordial germ cells via mitosis and meiosis. The initial cells on this pathway are known as spermatogonia, which yield important spermatocytes through mitosis. The main spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte divides into two spermatids via Meiosis II. These transform mature spermatozoa, sometimes called sperm cells. For that reason, the predominant spermatocyte offers rise to 2 cells, the secondary spermatocytes, and the two secondary spermatocytes through their subdivision produce four spermatozoa.
Spermatozoa are the mature male gametes in lots of sexually reproducing organisms. As a result, spermatogenesis is the male variation of gametogenesis. In mammals it occurs within the seminiferous tubules of the male testes in a stepwise fashion. Spermatogenesis is particularly stylish upon most advantageous stipulations for the method to occur safely, and is important for sexual replica. DNA methylation and histone change had been implicated in the legislation of this procedure. It starts at puberty and frequently continues uninterrupted except loss of life, even though a moderate cut down may also be discerned within the quantity of produced sperm with develop in age.

Spermatogenesis is the process by which spermatozoa are produced from male primordial germ cells through mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis. The primary spermatocyte divides meiotically into two secondary spermatocytes; each secondary spermatocyte then completes meiosis as it divides into two spermatids. These develop into mature spermatozoa, also known as sperm cells. Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa.[1]
Spermatozoa are the mature male gametes in many sexually reproducing organisms. Thus, spermatogenesis is the male version of gametogenesis. In mammals it occurs in the male testes and epididymis in a stepwise fashion. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. DNA methylation and histone modification have been implicated in the regulation of this process.[2] It starts at puberty and usually continues uninterrupted until death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age (see Male infertility).
Oogenesis, ovogenesis or oögenesis /ˌoʊ.əˈdʒɛnɨsɪs/[1] is the creation of an ovum (egg cell). It is the female form of gametogenesis; the male equivalent is spermatogenesis. It involves the development of the various stages of the immature ovum.
In mammals, the first part of oogenesis starts in the germinal epithelium, which gives rise to the development of ovarian follicles, the functional unit of the ovary.
Note that this process, important to all animal life cycles yet unlike all other instances of cell division, occurs completely without the aid of oo spindle-coordinating centrosomes.[2][3]
Oogenesis consists of several sub-processes: oocytogenesis, ootidogenesis, and finally maturation to form an ovum (oogenesis proper). Folliculogenesis is a separate sub-process that accompanies and supports all three oogenetic sub-processes. Source of the article published in description is Wikipedia. I am sharing their material.
