Location: Cells that lie between the Seminiferous Tubules

Location: In the Seminiferous Tubules
Function: Support/Nourish developing sperm

Vasa (Ductus) Deferentia (Vas Deferens) spec
Location: Duct also in the testes
Function: Storage duct for sperm before entry to Penis
Tube that Carrie’s sperm from Epidiymides to prostate
Cowper’s Gland & Prostate Gland specs
Location: At the best of the Penis
Function: Contributes alkaline and mucoid fluids to semen
Produces a milky fluid that contributes to semen
Alkaline fluid secreted for neutralization
Seminal Vesicles specs
Location: Base of the Penis
Function: Contributes Fructose & fluid to semen
Gives energy to sperm
Ejaculatory Duct
