spermatids
spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material. in spermatocytogenesis, a diploid spermatogonium, which resides in the basal compartment of the seminiferous tubules, divides mitotically, producing two diploid intermediate cells called primary spermatocytes. each primary spermatocyte then moves into the adluminal compartment of the seminiferous tubules and duplicates its dna and subsequently undergoes "meiosis i" to produce two haploid secondary spermatocytes, which will later divide once more into haploid spermatids. this division implicates sources of genetic variation, such as random inclusion of either parental chromosomes, and chromosomal crossover that increases the genetic variability of the gamete. the dna damage response (ddr) machinery plays an important role in spermatogenesis. the protein fmrp binds to meiotic chromosomes and regulates the dynamics of the ddr machinery during spermatogenesis. fmrp appears to be necessary for the repair of dna damage.

cell cycle analysis by dna content measurement is a method that most frequently employs flow cytometry to distinguish cells in different phases of the cell cycle. before analysis, the cells are usually permeabilised and treated with a fluorescent dye that stains dna quantitatively, such as propidium iodide (pi) or 4,6-diamidino-2-phenylindole (dapi). the fluorescence intensity of the stained cells correlates with the amount of dna they contain. as the dna content doubles during the s phase, the dna content (and thereby intensity of fluorescence) of cells in the g phase and g phase (before s), in the s phase, and in the g phase and m phase (after s) identifies the cell cycle phase position in the major phases (g/g versus s versus g/m phase) of the cell cycle. the cellular dna content of individual cells is often plotted as their frequency histogram to provide information about relative frequency (percentage) of cells in the major phases of the cell cycle.
