    About the Lecture

    The lecture Male Reproductive System: Testis by Geoffrey Meyer, PhD is from the course Reproductive Histology. It contains the following chapters:

    • Male Reproductive System: Testis
    • Testis
    • Seminiferous tubule
    • Spermatogenesis
    • Sertoli cell
    • Mature spermatozoon
    • Leydig cell
    • Hormonal control of spermatogenesis

    Included Quiz Questions

    1. The collagenous capsule of the testis has no sensory nerve supply (i.e. sensory innervation)
    2. Sperm become mature and motile in the ductus epididymis
    3. The capsule surrounding the testis is called the tunica albuginea
    4. Blood vessels within the capsule of the testis constitute the tunica vasculosa and penetrate the testis
    5. Septae (pleural of septum) divide the testis into lobules
    1. 12 to 60 metres (m)
    2. 12 to 60 centimetres (cm)
    3. 12 to 30 metres (m)
    4. 60 to 120 metres (m)
    5. 60 to 90 centimetres (cm)
    1. rete testis - ductuli efferentes (efferent ducts) - ductus epididymis (epididymis) - ductus (vas) deferens
    2. ductuli efferentes (efferent ducts) - rete testis - ductus epididymis (epididymis) - ductus (vas) deferens
    3. rete testis - ductus epididymis (epididymis) - ductuli efferentes (efferent ducts) - ductus (vas) deferens
    4. ductuli efferentes (efferent ducts) - rete testis - ductus (vas) deferens
    5. rete testis - ductus epididymis (epididymis) - ductus (vas) deferens
    1. the spermatogonial phase
    2. the spermatocyte phase
    3. the spermatid phase
    4. spermiogenesis
    5. the spermatogonial phase and the spermatocyte phase
    1. secretes androgen binding protein (ABP) which concentrates testosterone in the lumen of the seminiferous tubule
    2. secretes androgen binding protein (ABP) to form part of the blood - testis barrier
    3. secretes inhibin which concentrates testosterone in the lumen of the seminiferous tubule
    4. secretes androgen binding protein (ABP) which concentrates testosterone in the blood
    5. secretes testosterone into the lumen of the seminiferous tubule to maintain spermatogenesis
    1. are also called "interstitial cells of the testis" and secrete testosterone
    2. are also called "Sertoli cells of the testis" and secrete androgen binding protein (ABP)
    3. secrete testosterone only after puberty
    4. secrete testosterone and androgen binding protein into the blood
    5. concentrate testosterone in the lumen of the seminiferous tubule
    1. stimulates Sertoli cells to secrete androgen binding protein (ABP)
    2. stimulates Leydig cells to secrete androgen binding protein (ABP)
    3. stimulates Leydig cells to secrete testosterone
    4. inhibits secretion of androgen binding protein (ABP) by Sertoli cells
    5. inhibits secretion of testosterone by Leydig cells
