Verified step by step guidance
1
Begin by identifying the anatomical structures involved in the male reproductive system, specifically those related to the transport of sperm.
Understand the role of the ductus deferens (also known as the vas deferens) in transporting sperm from the epididymis to the ejaculatory duct.
Recognize that the ejaculatory duct is formed by the union of the ductus deferens and the duct of the seminal vesicle. It serves as a conduit for sperm to travel from the ductus deferens to the prostatic urethra.
Note that the prostatic urethra is a part of the urethra that passes through the prostate gland, and it is the next segment after the ejaculatory duct in the pathway of sperm.
Conclude that the ejaculatory duct is the specific tube that transports sperm from the ductus deferens to the prostatic urethra, distinguishing it from other structures like the seminal vesicle, vas deferens, and urethra.
