  2. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material. In spermatocytogenesis, a diploid spermatogonium , which resides in the basal compartment of the seminiferous tubules, divides mitotically, producing two diploid intermediate cells ...

    Schematic diagram of Spermatocytogenesis. Spermatocytogenesis is the male form of gametocytogenesis and involves stem cells dividing to replace themselves and to produce a population of cells destined to become mature sperm.

  4. Spermatocyte - Wikipedia

    en.wikipedia.org/wiki/Spermatocyte

    Each secondary spermatocyte will form two spermatids after meiosis II. [1] Although spermatocytes that divide mitotically and meiotically are sensitive to radiation and cancer, spermatogonial stem cells are not. Therefore, after termination of radiation therapy or chemotherapy, the spermatognia stems cells may re-initiate the formation of ...

    en.wikipedia.org/wiki/Gametocyte

    Gametogenesis is the formation or production of gametes (taking place during meiosis). The development and maturation of sex cells also takes place during meiosis. Gametogenesis is also the process of formation in male and female gametes that occur in the gonads (ovary and testis). Both male and female produce gametes.

    Sperm tail formation The sperm tail is a specialized type of cilium (aka flagella). In many animals the sperm tail is formed through the unique process of cytosolic ciliogenesis , in which all or part of the sperm tail's axoneme is formed in the cytoplasm or gets exposed to the cytoplasm.

    If the testicles remain too close to the body, it is likely that the increase in temperature will harm the spermatozoa formation, making conception more difficult. This is why the testes are carried in an external scrotum rather than within the abdomen; they normally remain slightly cooler than body temperature, facilitating sperm production.

  9. Spermatogonium - Wikipedia

    en.wikipedia.org/wiki/Spermatogonium

    A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell.Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testicles.
