Male reproductive system
The scrotum
(also called the scrotal sac) hangs under the penis and contains the testicles and epididymis.
Seminal Vesicles
Located at the base of the bladder, the two seminal vesicles secrete a thick fluid that nourishes the sperm.
Epididymis
Next to each testicle, the epididymis is a light-colored tube where sperm is stored and matured. From here, sperm are transported to the vas deferens.
Testicle
The two testicles (or testes) produce sperm and the male sex hormone testosterone.
Vas Deferens
Thin muscular tube transports the sperm from the epididymis to the urethra.
Prostate Gland
This walnut-sized gland surrounds a portion of the urethra and produces some of the fluid in semen.
Urethra
Tube that carries semen and urine out of the penis.
The penis
is made of two parts: the shaft (the main part) and the glans (the tip, sometimes called the head). The penis delivers sperm through the urethra.
The bladder
is the muscular sac that stores urine (pee) until it is released through the urethra.
