Male urogenital system artwork. The bladder (orange, upper centre) holds urine, which it receives from the kidneys (not seen). Urine is excreted from the bladder through the urethra, seen extending from the base of the bladder to the penis at far left. The urethra also carries sperm and seminal fluids during ejaculation. Sperm is produced in the testes (bottom left) and is passed up the vas deferens tube to the prostate gland (purple, centre), where it joins with the urethra. The prostate gland produces seminal fluids, which form much of the ejaculate.
