The sperm itself already has got the ability to swim, though the seminal vesicles add fluid with the provided energy to the cell mass.
The spermatozoa is formed in the testis and is stored in the epididymis. While traveling through the epididymis the sperm mature and gain motility and the ability to fertilize.
The flagellum (pl. flagella) provides movement for the sperm cell.

Roosters have internally located testicles which produce sperm. The sperm leaves the testicles and enter the epididymis. The epididymis is where the sperm gain the ability to swim. They then enter the vas deferens where they are store until mating.
