Spermatozoa

More information in Books or onNLM PubMed
Definition: Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.  polyspermia & polyspermy   
See Also Antispermatogenic Agents; Oligospermia; Sperm Banks; Spermatocidal Agents
Examples Sperm Head; Sperm Midpiece; Sperm Tail; Spermatids; Spermatocytes; Spermatogonia
