Verified step by step guidance

1. Understand the role of the urethra in the male body. The urethra is a tube that carries urine from the bladder to the outside of the body, which is part of the excretory system.
2. Recognize that the urethra also serves a reproductive function in males. It is the channel through which semen is expelled during ejaculation.
3. Differentiate the urethra from other structures listed. The ureter is part of the urinary system, transporting urine from the kidneys to the bladder, but not involved in reproduction.
4. Identify the seminal vesicle as a gland that contributes fluid to semen, but it does not serve an excretory function.
5. Understand that the epididymis and vas deferens are involved in sperm transport and maturation, but they do not have a direct role in excretion.
