Verified. Hint: Spermatogenesis and oogenesis are the processes of formation of male and female gametes respectively. Male gamete that is sperms is produced through the process of spermatogenesis and eggs, female gametes are produced through oogenesis. These gametes fuse to form a single cell called zygote which develops into a complete organism. Mammalian spermatogenesis requires a stem cell pool, a period of amplification of cell numbers, the completion of reduction division to haploid cells (meiosis), and the morphological transformation of the haploid cells into spermatozoa (spermiogenesis). The net result of these processes is the production of massive numbers of spermatozoa over Understanding: • Spermatogenesis and oogenesis both involve mitosis, cell growth, two divisions of meiosis and differentiation. Gametogenesis is the process by which diploid precursor cells undergo meiotic division to become haploid gametes (sex cells) In males, this process is called spermatogenesis and produce spermatozoa (sperm) In females Oatley, MJ, Kaucher, AV, Racicot, KE, Oatley, JM. Inhibitor of DNA binding 4 is expressed selectively by single spermatogonia in the male germline and regulates the self-renewal of spermatogonial stem cells in mice. Biol Reprod 2011; 85: 347–56.

These cells can be found in the male testis' tiny tubules. A diploid cell with 2n chromosomes is the spermatogonium. Each spermatogonium produces four haploid (n) spermatozoa. Nature of the process: Spermatogenesis is the male version of gametogenesis which results in the formation of mature male gametes whereas oogenesis is the female version of gametogenesis which results in the formation of mature male gametes. Occurrence: Spermatogenesis occurs in the testes until the sperm moves to the epididymis and gains Explain the process of spermatogenesis in detail. Medium.

Class 5 Spermatids are the outcome of the first meiotic division of primary spermatocytes, which produces a pair of spermatocytes to complete meiosis (second division). Spermatids are produced via the spermatogenesis process, and cells engage in spermiogenesis to create spermatozoa. Spermatids have 23 chromosomes and are haploid. It grows through maturation from the original oocyte. The embryonic stage is when oogenesis begins. In Oogenesis there is only one ovum is produced due to unequal division of meiosis producing one haploid cell. Mature eggs are produced during female gametogenesis or oogenesis. Meiosis causes 4 haploid cells to divide into a single egg. Unlike a few years ago, when the relevance of FSH in adult spermatogenesis was questioned, it has become clear that FSH – probably more so than testosterone – is the key regulator of primate spermatogenesis. The present chapter aims at providing a state-of-the-art review of our current understanding of the role of testosterone in vzqULKJ.
