Gametes, gametogenesis and spermatogenesis

ImportantEssential Concepts
  • Gametes are haploid reproductive cells with 23 chromosomes.
  • Mature gametes only form at puberty.
  • They originate from germ cells that appear in the 3rd week of development / 21st day
  • Meiosis consists of 2 successive specific cell divisions
    • Meiosis I:
      • consists of the segregation of homologous chromosomes into 2 daughter cells
    • Meiosis II:
      • consists of the segregation of sister chromatids in each daughter cell
    • Genetic recombination (crossing-over) occurs during the first meiotic division
    • Non-disjunction anomalies lead to monosomies and trisomies, including sex chromosome syndromes (that should be known).
    • Meiosis is fixed and continuous in males, but discontinuous and incomplete in females.
  • Spermatogenesis:
    • Spermatogenesis can only occur correctly if the testicles descend into the scrotal position early during fetal life (between the 7th and 9th month).
    • The testicle plays both an endocrine and exocrine role.
    • Spermatogenesis occurs in the seminiferous tubules.
    • Sertoli cells play a major role in spermatogenesis. Know the characteristics of Sertoli cells and their role.
    • The seminiferous tubules are divided into two compartments in which different germ cells are found.
    • Between the seminiferous tubules is located the interstitial tissue where Leydig cells are found, which produce testosterone.
    • The blood-testis barrier (barrière homéotesticulaire) (know its constitution) plays an immune role (know the different roles).
