Final answer:
Sperm cells move along the ductus deferens due to peristaltic contractions, aiding in their journey for potential fertilization.
Explanation:
The ability of sperm cells to move along the ductus deferens is due to peristaltic contractions. The peristaltic contractions of smooth muscle in the ductus deferens help propel sperm from the epididymis and through the reproductive tract, aiding in ejaculation. This movement is crucial for sperm to reach the egg for fertilization.
