  2. 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.

  3. 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.

    A testicle or testis (pl. testes) is the gonad in all male bilaterians, including humans, and is homologous to the ovary in females. Its primary functions are the production of sperm and the secretion of androgens, primarily testosterone. The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland.

    Dihydrotestosterone (DHT) is a metabolite of testosterone, and a more potent androgen than testosterone in that it binds more strongly to androgen receptors. It is produced in the skin and reproductive tissue. A4 and testosterone can also have an extra hydroxyl (-OH) or keton (=O) group bound on position 11.

  7. Leydig cell - Wikipedia

    en.wikipedia.org/wiki/Leydig_cell

    Leydig cells release a class of hormones called androgens (19-carbon steroids). [8] They secrete testosterone, androstenedione and dehydroepiandrosterone (DHEA), when stimulated by the luteinizing hormone (LH), which is released from the anterior pituitary in response to gonadotropin releasing hormone which in turn is released by the hypothalamus.

  8. Lobules of testis - Wikipedia

    en.wikipedia.org/wiki/Lobules_of_testis

    They differ in size according to their position, those in the middle of the gland being larger and longer. The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis.
