Final answer:
The straight tubules in the testes connect to the rete testis and efferent ductules before entering the epididymis.
Step-by-step explanation:
The straight tubules in the testes originate from the seminiferous tubules and lead to a network of passageways called the rete testis. From there, sperm leave the rete testis and the testis itself through the efferent ductules. These ductules cross the tunica albuginea and transport the sperm to the epididymis.
