Verified step by step guidance

Step 1: Begin by understanding the anatomy of the male reproductive system. The testes are responsible for producing sperm, which then travel through a series of structures before being expelled through the urethra during ejaculation.
Step 2: Identify the first structure sperm enters after being produced in the testes. Sperm are stored and mature in the epididymis, which is located on the posterior side of the testes.
Step 3: Next, sperm travel from the epididymis into the vas deferens (also called the ductus deferens). The vas deferens is a muscular tube that transports sperm during ejaculation.
Step 4: The vas deferens leads to the ejaculatory duct, which is formed by the union of the vas deferens and the duct of the seminal vesicle. The ejaculatory duct passes through the prostate gland and empties into the urethra.
Step 5: Finally, sperm exit the body through the urethra, which is the shared passage for urine and semen in males. The correct route is: Epididymis β vas deferens β ejaculatory duct β urethra.
