A chromatoid is a structure found in the cytoplasm of certain cells, particularly in male germ cells, and is associated with the process of spermatogenesis. It is often described as a rod-like or filamentous body that contains RNA and is involved in the synthesis of proteins necessary for sperm development. Chromatoids play a role in the organization and storage of genetic material during cell division. They are distinct from chromosomes, which are the structures that carry genetic information within the nucleus.
