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. This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Spermatozoa known by any other names?
Yes. Spermatozoa is also referred to as Sperm, Spermatozoon, X-Chromosome-Bearing Sperm, Sperms, X-Chromosome-Bearing in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
