This study shows that the function of the cytoplasmic granule, the late chromatoid body, is connected to translational regulation in condensing spermatids.<h4>Abstract</h4>Spermatogenesis culminates in a dramatic morphological transformation, including a tight compaction of the chromatin and nuclear reshaping that largely silences transcription. Due to transcriptional silencing, the production of sperm-specific proteins needed for the morphological transformation requires active storage and translational regulation of mRNAs transcribed in earlier cell types.
