Ultrastructural cytochemical study of the nuage in the human adult testis revealed that this structure was a cytoplasmic fine fibrillar electron-dense mass, similar to the chromatoid body of spermatids, in all spermatogonial types and spermatocytes. The nuage was often observed in relation with the nucleus or mitochondria. Cytochemical techniques showed staining affinity of the nuage for both ethanolic phosphotungstic acid and ethylene diamine tetra-acetic acid. The intermitochondrial bars were also stained with the two procedures. The results suggest that the nuage originates from the nucleus and migrates to the cytoplasm through nuclear pores, giving rise to the intermitochondrial bars.
