    en.wikipedia.org/wiki/Seminiferous_tubule

    Sertoli cells function to nourish the developing sperm cells. They secrete androgen-binding protein , a binding protein which increases the concentration of testosterone. There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis.

  6. 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 ...

  7. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    The process of spermatogenesis as the cells progress from primary spermatocytes, to secondary spermatocytes, to spermatids, to Sperm Cycle of the seminiferous epithelium of the testis Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material.

  8. Sperm - Wikipedia

    en.wikipedia.org/wiki/Sperm

    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.

  9. Spermatogonium - Wikipedia

    en.wikipedia.org/wiki/Spermatogonium

    The overall structure of spermatozoa is very specialized as the cell has fully differentiated and matured. As spermatozoa, the cell no longer undergoes division. It consists of a head, midpiece, and flagella tail for motility. Head: As the head of the sperm, it is an ovular shape consisting of the nucleus and the acrosome. [4]
