Sperm - Male reproductive cell

7. Epididymis a long tube located along the testicles
complete their maturation
stored in the lower portion
immature and incapable of fertilizing

8. Vas Deferens Tubes Matures travel to the seminal vesicle
Tubes that extend from epididymis to urethra

9. Seminal Vesicle Produces nourishing fluid
contains fructose, which provides an energy source for the sperm; prostaglandins, which contribute to the mobility and viability of the sperm; and proteins that cause slight coagulation reactions in the semen after ejaculation.

10. Prostate Gland size of a walnut secretions

urethra
It is a passageway for sperm and fluids from the reproductive system and urine from the urinary system. While reproductive fluids are passing through the urethra, sphincters contract tightly to keep urine from entering the urethra.

13. Problems with male reproductive system
Hernia
Sterility
Testicular cancer
Prostate cancer
Hernia – intestine rips through ab wall by top of scrotum
