Spermatidogenesis

Definition

noun

The intermediate stage of spermatogenesis that is highlighted by the meiotic division of the spermatocytes, giving rise to haploid spermatids, each with a different genetic content.


Supplement

Every primary spermatocyte that develops from being a spermatogonium moves into the adluminal compartment of the seminiferous tubules. It duplicates its DNA and undergoes meiosis I, resulting in the formation of two secondary spermatocytes that immediately enter meiosis II. As a result, four haploid spermatids are formed.

Spermatidogenesis occurs in the male gonad of sexually reproducing organisms. It is the male counterpart of ootidogenesis in females.


Compare: ootidogenesis
