Primary sexual characterists

the testicles produce mass sperm producing tubes called seminiferous tubules

the tubes join to form a duct leading to the epididymis

the epididymis leads to the muscular sperm tubes

the two sperm ducts one from each testicle open in the urethra

the sperm duct passes the seminal vesicles and prostate gland before opening into the urethra

the urethra passes through the penis and contracts either urine or semen at different time
