Male Reproductive Physiology Flashcards
What are the primary reproductive organs of the male?
testes
Epididymus
sperm storage
Vas deferens
duct work
Seminal vesicles
fructose and prostaglandins
Prostate
alkaline mucus ( neutralizes acidity of the urethra) and clotting factors
Bulbourethral glands
lubricating mucus
Penis
more duct work
Sertoli Cells
make up walls of seminiferous tubules and forms blood testes barrier, nourish developing sperm cells
Leydig cells
scattered in the interstitium surround the seminiferous tubules, make and release testosterone
What is the location of spermatoza
between 2 adjacent sertoli cells
Role of tight junctions
between sertoli cells and protect sperm from immune attack
What do sertoli cells secrete?
luminal fluid and androgen-binding protein which keeps local testosterone levels high
How do sertoli cells respond to testosterone and FSH
secreting paracrine agents that regulate spermatozoa maturation
