- A cell in a late stage of the development of the spermatozoon; it is a haploid cell derived from the secondary spermatocyte and evolves by spermiogenesis into a spermatozoon. SYN: nematoblast. [spermat- + -id (2)]
* * *sper·ma·tid 'spər-mət-əd n one of the haploid cells that are formed by the second meiotic division of a spermatocyte and that differentiate into spermatozoa compare OOTID
* * *n.a small cell produced as an intermediate stage in the formation of spermatozoa. Spermatids become embedded in Sertoli cells in the testis. They are transformed into spermatozoa by the process of spermiogenesis (see spermatogenesis).
* * *sper·ma·tid (spurґmə-tid) a cell derived from a secondary spermatocyte by fission, and capable of undergoing spermiogenesis to develop into a spermatozoon; called also spermatoblast.
