The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens. The seminiferous tubules of the testis open into the vasa efferentia through rete testis. The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder. It receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct. These ducts store and transport the sperms from the testis to the outside through urethra. The urethra originates from the urinary bladder and extends through the penis to its external opening called urethral meatus.
NTA tests students on the complete route sperm travels from seminiferous tubules to urethra: seminiferous tubules → rete testis → vasa efferentia → epididymis → vas deferens → ejaculatory duct → urethra. The common mistake is confusing the order of these ducts or forgetting that seminal vesicle contributes a duct to the vas deferens before it becomes the ejaculatory duct. Students often mix up epididymis (storage/maturation site) with vas deferens (transport duct). Remember: each testis has its own epididymis and vas deferens, and the ejaculatory duct forms only after the seminal vesicle duct joins the vas deferens. This sequential pathway is repeatedly tested because it's fundamental to understanding male reproductive anatomy.
