Male reproductive system

• Scrotum: The external pouch, ventral to the anus, which contains the testes
• Testes: The small, bean-shaped male reproductive organs contained within the scrotum which produce sperm and testosterone
• Epididymis: The band-shaped collection of tubules with a coiled duct that lays on the testis. It is used for sperm storage and maturation
• Ductus deferens: The ducts that transfer sperm from the epididymis to the urethra during an ejaculation.  It is called the “vas deferens” in humans
• Inguinal canal: The passageway through the abdominal wall in the groin of males though which the ductus deferens and blood vessels pass to the testes
• Seminal vesicles: These small glands are located near the junction of the ductus deferens and the urethra. They produce some of the seminal fluid
• Prostate gland: A small gland located between the seminal vesicles, which surrounds the junction of the ductus deferens and the urethra. It produces some of the seminal fluid
• Penis: The male copulatory organ located ventrally on the exterior abdominal wall, just posterior to the umbilical cord
• Bulbourethral glands: A pair of glands near the base of the penis in the pelvic canal on either side of the urethra. They produce some of the seminal fluid. They are also called “Cowper’s glands.”
• Urogenital Opening: The opening that is the terminal end of the male urogenital tract. Located just below the umbilical cord in the fetal pig
