Pathway of sperm

1. Testes

2. Epididymis

3. Vas deferens

4. Ejaculatory duct

5. Urethra

Vas deferens

Tube carries sperm from testes to urethra

Ejaculatory duct

Propels movement of sperm and fluids called semen into urethra

Epididymis

matures and stores sperm cells in coiled tubules

Vasectomy

A means of birth or control where the vas deferens is surgically cut

Spermatogenesis

process by

which spermatogonia divide and

differentiate into mature sperm cells

Seminiferous tubules

coiled ducts

found within the testes, where

immature sperm cells divide and

differentiate

Spermatocytes

cell that arises

from division of spermatogonia

during spermatogenesis

Spermatogonia

sperm-producing

cells found in the seminiferous

tubules

Sertoli cell

Nourishes developing sperm cell untill mature. Provide barrier between blood and seminiferous tubules. Barrier controls entry and exit of hormones, nutrients and other chemicals which protects sperm
