SPERMATOGENESIS

• Spermatogonium

  As germ cells mature they move from the basement membrane of the tubule to the tubular lumen.
• Spermatogenesis


  The process of producing the sperm which happens in the seminiferous tubules of the testes
• Primary Spermatocyte

  produced by mitosis, primary spermatocytes, like spermatogonia, are diploid and have46 chromosomes.
• Secondary Spermatocyte

  Produced by first meiotic division, meiosis I, to produce two secondary spermatocytes, a haploid cell each with 23 chromosomes
• Spermatids

  As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte
• Spermiogenesis

  During this process pronounced changes occur in the nucleus and cytoplasm.
• Sperm

  The nucleus becomes progressively darker and elongated.
