A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents. The replacement, within chromatin, of resident histones or histone subunits with alternative, sometimes variant, histones or subunits. The specialization of the spermatid nucleus during the development of a spermatid into a mature male gamete competent for fertilization. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. Dynamic structural changes to eukaryotic chromatin that require energy from the hydrolysis of ATP, ranging from local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation, mediated by ATP-dependent chromatin-remodelling factors. Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin. Any process by which DNA and associated proteins are formed into a compact, orderly structure. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of one or more nucleosomes. The progressive compaction of the spermatid chromatin so that it reaches a level of condensation that is not compatible with nuclear activities such as transcription or DNA replication. The replacement of somatic histones within sperm chromatin with sperm-specific histones or protamines with unique DNA-binding properties, resulting in condensation of the sperm chromatin.
