What is the function of the vasa efferentia in a frog?

The vasa efferentia in a frog are a series of small ducts that transport sperm from the seminiferous tubules of the testes to the vas deferens. This structure plays a crucial role in the reproductive system, as it facilitates the movement of sperm during mating. By connecting the testes to the reproductive tract, the vasa efferentia ensure that sperm is efficiently delivered for fertilization.
