During ejaculation sperms are released from:
Spermatogenesis takes place in the seminiferous tubules. Sperms from the seminiferous tubules travels along the straight tubule to the rete testis where they are concentrated and then to the efferent tubule and to the epididymis where they are stored until ejaculation. Epididymis is the reservoir of spermatozoa. Ref: Human anatomy, by B.D Chaurasia, 4th Edition, Volume II, Page 218
