    Description

    This is a power point presentation of Spermatogenesis.
    Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of 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.
