Vas Deferens - tubes that extend from each epididymis to the urethra Seminal Vesicle -first stop fluid

Prostate Gland - more fluid - Common site of cancer - Rectal exam after 40/50 Cowper’s Gland - secrets more fluid -Prepares urethra Urethra - exit for semen & urine Semen – thick fluid containing sperm and other secretions
