| | The vas deferens arises from the posterior margin of the main axis of the testis and opens to the exterior through genital pores located medially on the coxopod of the fifth pereiopod. | | | The lobes are connected to each other at their inner ends and lead to the next organ, the vas deferens. | | | Each vas deferens consists of four distinct portion; a short, narrow, proximal medial oprtion having a double fixture (median vas deferens); a relatively long narrow tube (distal vas deferens); and a muscular portion (terminal ampoule). |
