Penile urethra
List the major components of seminal fluid and their functions.
- Fructose - ATP production
- Prostoglandins - Sperm motility and viability
- Clotting Proteins - Coagulation of semen
List the major components of prostatic fluid and their functions.
- Calcium, Citrate, and Phosphate ions
- Enzymes - Clotting & Protein hydrolyzing
What is secreted by the bulbourethral gland and what is its function?
Mucus - Newtralizes urea and lubricates
What erectile tissue does the penlie urethra travel through?
Corpus spongiosum
List the structures located in the spermatic cord.
- Testicular artery
- Pampinoform plexus of veins
- Autonomic nerves
- Lymphatic vessels
- Vas deferens
Where are sperm made?
Seminiferous tubules
Where are sperm stored?
Epididymis
What moves the sperm through the epididymis and vas deferens?
Peristaltic contractions
What is the function of the cilia in the epididymis?
Monitor and adjust fluid composition
What is the function of steroli cells?
- Maintain blood testis barrier
- Supports mitosis & meiosis
- Supports spermatogenesis
- Secretes inhibin
- Secretes androgen-binding protein
- Secretes mullerian-inhibiting factor
What hormone stimulates the sertoli cells?
FSH - Follicle Stimulating Hormone
Sertoli cells produce ___________ (concentrates testosterone in the seminiferous tubules).
Androgen-binding protein
When sperm production is too high, Sertoli cells secrete ________, which inhibits the secretion of FSH and GnRH.
Inhibin
Interstitial cells (Leydig cells) produce the hormone _________, when stimulated by the __________ (from the pituitary gland).
Testosterone; Luteinizing hormone
