Quizplus · Accepted Answer

Spermatogenesis occurs along the walls of the seminiferous tubules,within the testes.Cells of more advanced stages are located progressively inward,such that the mature sperm are released into the tubule lumen.Cells within the seminiferous tubules are continuously developing from spermatogonia into spermatocytes and eventually to sperm,so at any one time,all types of cells are present along the seminiferous tubule.Sperm moving out of the seminiferous tubules are emptied into the epididymis,a very long,coiled,tubular structure located on the surface of the testis.Here the sperm complete their differentiation by becoming motile and gaining the capacity to fertilize ova.The seminal vesicles on the other hand,secrete the monosaccharide fructose,the main nutrient for sperm,as well as other factors that enhance sperm motility and survival.However,they are not the location where sperm gain motility.
