Spermiation — the sperm release process: Ultrastructural observations and unresolved problems

  • Lonnie D. Russell
Part of the Electron Microscopy in Biology and Medicine book series (EMBM, volume 2)

Abstract

The release of germ cells from the epithelium of the seminiferous tubule signals the end of spermatogenesis and the beginning of the passage of these highly differentiated cells through the excurrent duct system. At the time of release germ cells no longer should be termed spermatids but spermatozoa or, simply, sperm. Sperm have attained virtually their final form at the time they are liberated; however, they are functionally immature and still lack the capacity to fertilize.
