  • The right testis lies lower than the left
  • Lymph from the testis drains to the para-aortic and pre-aortic nodes at L1
  • Both testicular veins run intraperitoneally as they traverse the surface of psoas major
  • The testicular arteries arise from the abdominal aorta at L2
  • The most external layer of fascia surrounding the testis is the tunica albuginea

Where does the right testicular vein drain to?

  • Abdominal aorta
  • Right renal artery
  • Inferior vena cava

What is the function of the seminiferous tubules?

  • Production of fructose
  • Production of testosterone
  • Propelling the spermatozoa to the vas deferens
  • Production of spermatozoa
  • Degradation of sperm

Where is the rete testis found?

  • In the vas deferens

  • In the spermatic cord
  • Between the parietal and visceral layers of the tunica vaginalis

What is the role of the fluid between the layers of the tunica vaginalis?

  • To keep the testis cool
  • To allow sperm to travel from the testis to the spermatic cordd
  • To allow the testis to move within the scrotum

  • The seminferous tubules
  • The rete testis
  • The tunica vasculosa

What is the function of the epididymis?

  • Production of testosterone
  • Production of sperm
  • Erectile tissue
  • Production of prostaglandins
  • Storage and maturation of spermatozoa

What is the role of the Sertoli cells?

  • To nourish the spermatozoa and form blood-testis barrier
  • To produce spermatozoa and form blood-testis barrier
  • To transport spermatozoa
  • To produce testosterone and form blood-testis barrier
  • To degrade spermatozoa
