The formation of the acrosome from the spermatid Golgi. The generation and maintenance of gametes in a multicellular organism. A gamete is a haploid reproductive cell. The specialization of the spermatid nucleus during the development of a spermatid into a mature male gamete competent for fertilization. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. The assembly and organization of the sperm flagellar axoneme, the bundle of microtubules and associated proteins that forms the core of the eukaryotic sperm flagellum, and is responsible for movement. Fusion of mitochondria during insect spermatid differentiation to form two masses, which wrap around each other to form a densely packed sphere called the Nebenkern. The resolution of the male germline syncytium or cyst into individual gametes by packaging each spermatid into its own plasma membrane. The process whose specific outcome is the progression of a male gamete over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. The process whereby a relatively unspecialized cell acquires the specialized features of a spermatid cell. The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis. The process whose specific outcome is the progression of an immature germ cell over time, from its formation to the mature structure (gamete). A germ cell is any reproductive cell in a multicellular organism. The process whereby relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. The process whose specific outcome is the progression of the cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate. A process required for sperm to reach fertilization competence. Sperm undergo an incompletely understood series of morphological and molecular maturational processes, termed capacitation, involving, among other processes, protein tyrosine phosphorylation and increased intracellular calcium.
