    Single bull sperm cells enter these microtubes and become trapped inside. The tail of the sperm is the driving force for the microtube. [1] The second type, the helical spermbot, is a small helix structure which captures and transports single immotile sperm cells. In this case, a rotating magnetic field drives the helix in a screw-like motion.

  3. Spermatozoon - Wikipedia

    en.wikipedia.org/wiki/Spermatozoon

    The sperm cell of Homo sapiens is the small reproductive cell produced by males, and can only survive in warm environments; upon leaving the body, it starts to degrade, thereby decreasing the total sperm quality. Sperm cells normally come in two types, "female" and "male", named for the resulting sex of the fertilized zygote each produces after ...

  4. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis. These develop into mature spermatozoa, also known as sperm cells. [2] Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa and four haploid ...

    Sperm cells cannot divide and have a limited lifespan, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell with 46 paired chromosomes.

  6. Spermatogonium - Wikipedia

    en.wikipedia.org/wiki/Spermatogonium

    Spermatogenesis is the process in which sperm cells are produced and formed into mature spermatozoa from spermatogonia. Males mature spermatozoa (sperm) are produced to later join with a female oocyte (egg) to create offspring. Throughout the process of spermatogenesis, there are many different parts of the male anatomy, accessory organs, and ...

  8. Spermatocytogenesis - Wikipedia

    en.wikipedia.org/wiki/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. The stem cells involved are called spermatogonia and are a specific type of stem cell known as gametogonia .
