Final answer:
Scarring of the rete testis would interfere with a man's ability to deliver spermatozoa to the epididymis.
Step-by-step explanation:
Scarring of the rete testis would interfere with a man's ability to deliver spermatozoa to the epididymis. The rete testis is a network of tubules in the testes that connects the seminiferous tubules, where sperm are produced, to the epididymis, where sperm mature and are stored. If the rete testis is scarred, it can block the movement of sperm from the seminiferous tubules to the epididymis, resulting in infertility.
