The elongated structure that runs up the posterolateral aspect of the testes and caps its superior aspect is the epididymis.
The epididymis is the narrow, tightly coiled tube that connecting the testicles to the vas deferens. Epididymis is a elongated structure on the posterior surface of the testis.
The efferent ductules transport the newly developed sperms from the testis to rete testis and from rete testis to vas deferens the sperms transported through epididymis. Sperms took 10 to 15 days to cover epididymis.
Their transport is achieved primarily by rhythmic contractions of the smooth muscle layer surrounding the epididymis.
