Final answer:
The reproductive system includes the testes and epididymis, but not the ureter, which is part of the urinary system.
Step-by-step explanation:
The question is asking which structure is not part of the reproductive system. The male reproductive system includes the testes, which produce sperm and secrete testosterone, the, which is involved in sexual intercourse and is the conduit for sperm to leave the body, and the epididymis, which is where sperm mature and are stored. The ureter, on the other hand, is not part of the reproductive system; it is part of the urinary system and is responsible for carrying urine from the kidneys to the bladder. Therefore, the correct answer is: c. ureter.
