spermatocyte

Examples of spermatocyte in the following topics:

• Spermatogenesis

  • Each primary spermatocyte divides into two secondary spermatocytes and each secondary spermatocyte into two spermatids or young spermatozoa.
  • Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, which in turn produce four spermatozoa.
  • Secondary spermatocytes later divide into haploid spermatids.
  • 2) Spermatidogenesis: The creation of spermatids from secondary spermatocytes.
  • Diagram of the steps of spermatocytogenesis, including type Ad spermatogonium, type Ap Spermatogonium, type B spermatogonium, primary spermatocyte, and secondary spermatocyte.

• Gametogenesis (Spermatogenesis and Oogenesis)

  • Meiosis begins with a cell called a primary spermatocyte.
  • At the end of the first meiotic division, a haploid cell is produced called a secondary spermatocyte.
  • Four sperm result from each primary spermatocyte that goes through meiosis.
  • During spermatogenesis, four sperm result from each primary spermatocyte, which divides into two haploid secondary spermatocytes; these cells will go through a second meiotic division to produce four spermatids.

• Hormonal Regulation of the Reproductive System

  • In males, FSH stimulates primary spermatocytes to undergo the first division of meiosis, to form secondary spermatocytes, leading to the maturation of sperm cells.

• Semen

  • Sertoli cells, which nurture and support developing spermatocytes, secrete a fluid into seminiferous tubules that helps transport sperm to the genital ducts.
