Verified step by step guidance
1
Step 1: Begin by identifying the primary function of each structure listed in the options. For example, the seminal vesicle is responsible for producing seminal fluid, which is a component of semen, but it does not conduct urine.
Step 2: Understand the role of the epididymis. It is a coiled tube located on the back of the testicle that stores and transports sperm, but it does not conduct urine or semen.
Step 3: Examine the vas deferens. This structure transports sperm from the epididymis to the ejaculatory ducts during ejaculation, but it does not conduct urine.
Step 4: Focus on the urethra. The urethra is a shared pathway in males that conducts both semen during ejaculation and urine during urination. This dual function makes it unique among the listed structures.
Step 5: Conclude that the correct answer is the urethra, as it is the only structure in the male reproductive system that serves both functions of conducting semen and urine.
