Include rete testis, vasa efferentia, epididymis & vas deferens.
Seminiferous tubules unite to form straight tubules → open into rete testis (irregular cavities) → Vasa efferentia (series of fine tubules that conduct sperms) → epididymis (stores sperms temporarily) → vas deferens → join with a duct from seminal vesicle to form common ejaculatory duct → opens into urethra → urethral meatus (external opening).
The urethra receives the ducts of the prostate and Cowper’s glands and passes through the penis.
