The testis (held in an extension of the abdomen called the scrotum) is where sperm is formed.

Sperm complete maturation in the epididymis, and is stored in the vas deferens (ductus deferens).

Seminal fluid is produced in the seminal vesicle, prostate gland, and bulbourethral gland.

The seminal fluid mixes with sperm to yield semen and exits via the urethra, which is also the exit duct from the urinary bladder.
