Testicle begins development in mesonephric region of the embryo and is pulled, by the gubernaculum, along with a fold of the peritoneum into the scrotal region
Location outside of the body cavity is important for temperature control, testicle must be 2-4 deg. below body temperature for sperm production
Temperature control
Spermatic cordSpermatic arteryPampiniform plexusDeferent duct (vas deferens) Cremaster muscle
Scrotal sacLocation
Thermosensors in skin
Sweat glands
Insulation
Tunica dartos

Sertoli Cells (nurse cells)
Receptors for FSH & testosterone
Produce – androgen binding protein - sulfated glycoproteins - transferin - inhibin
Junctional complexes
Leydig Cells (interstitial cells)
Receptors for LH
Produce Testosterone
Spermatogonia – division by mitosis
Spermatocytes – division by meiosis
Intercellular bridges
Seminiferous Tubule – cross section

Epididymis
Rete Testis
Head – not motile - proximal cytoplasmic droplet
Body – gain motility - cytoplasmic droplet moves distal
Tail – progressive forward motility - rotational movement - only a few distal cytoplasmic droplets - fertile potential - primary storage site
Ejaculation
