  2. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    A single Sertoli cell extends from the basement membrane to the lumen of the seminiferous tubule, although the cytoplasmic processes are difficult to distinguish at the light microscopic level. Sertoli cells serve a number of functions during spermatogenesis, they support the developing gametes in the following ways:

  3. Seminiferous tubule - Wikipedia

    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.

  4. Male reproductive system - Wikipedia

    en.wikipedia.org/wiki/Male_reproductive_system

    The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.

  5. Germinal epithelium (male) - Wikipedia

    en.wikipedia.org/wiki/Germinal_epithelium_(male)

    The cells in the epithelium are connected via tight junctions. There are two types of cells in the germinal epithelium. The large Sertoli cells (not dividing) function as supportive cells to the developing sperm. The second cell type is the cells belonging to the spermatogenic cell lineage. These eventually develop into sperm cells ...

  6. Spermatocyte - Wikipedia

    en.wikipedia.org/wiki/Spermatocyte

    Spermatogonia going through mitosis to form primary spermatocytes in Grasshopper testes. Spermatocytogenesis. At puberty, spermatogonia located along the walls of the seminiferous tubules within the testis will be initiated and start to divide mitotically, forming two types of A cells that contain an oval shaped nucleus with a nucleolus attached to the nuclear envelope; one is dark (Ad) and ...

  7. Human reproductive system - Wikipedia

    en.wikipedia.org/wiki/Human_reproductive_system

    Male reproductive system. The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. [3] Penile shrinkage due to low ...

  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. Tunica vaginalis - Wikipedia

    en.wikipedia.org/wiki/Tunica_vaginalis

    The tunica vaginalis is a pouch of [2] serous membrane [3] within the scrotum that lines the testis and epididymis (visceral layer of tunica vaginalis), and the inner surface of the scrotum (parietal layer of tunica vaginalis).
