Process of Spermatogenesis. Spermatogenesis begins in the seminiferous tubules of the testes. Sperm pass into the epididymis where they mature and become motile so they are able to move through the vas deferens and into the seminal vesicles where they mix with seminal fluids, rich in fructose and other nutrients.he testes are the male gonads and contain hundreds of tiny seminiferous tubules where sperm cells are produced.
