The first comprises the cells from the spermatogonium up to and including the secondary spermatocyte and is termed spermatocytogenesis. The second one comprises the differentiation/maturation of the sperm cell, starting with the spermatid phase and is termed spermiogenesis (or spermiohistogenesis. Spermatocytogenesis is the first stage of spermatogenesis which involves the division of single diploid cells into four haploid spermatocytes. The testis is composed of numerous tightly coiled tubules called seminiferous tubules which are lined with stem cells. The immature cells called spermatogonia are formed from these stem cells. Study with Quizlet and memorize flashcards containing terms like Which hormone is absolutely necessary for ovulation to occur? A) LH B) progesterone C) estrogen D) FSH, A human egg or sperm contains 23 pairs of chromosomes. (T/F), The cells that produce testosterone in the testis are called ________. A) spermatocytes B) sustentacular cells C) spermatogonia D) interstitial endocrine cells and more.
Background Spermatogenesis is a cellular differentiation process that includes three major events: mitosis of spermatogonia, meiosis of spermatocytes and spermiogenesis. Steady-state spermatogenesis relies on functions of spermatogonial stem cells (SSCs). Establishing and maintaining a foundational SSC pool is essential for continued spermatogenesis in mammals.

Difference Between Spermatogenesis and Spermiogenesis Definition. Spermatogenesis: Spermatogenesis is the formation of motile spermatozoa from spermatogonium. Spermiogenesis: Production. Spermatogenesis: Four functional spermatozoa are produced from a spermatogonium during the spermatogenesis.
Male Reproductive System: Spermatogenesis The production of sperm and eggs/ova (gametes) is a procedure called gametogenesis (spermatogenesis and oogenesis). Gametogenesis involves two rounds of meiotic cell division, in which one diploid cell gives rise to 4 haploid cells. s3WM. 394 403 242 151 87 229 173 73 399
