In the present study propidium iodide was used as a fluorescent dye to stain DNA of cells of hamster testicular origin and fluorescent intensities were analyzed by flow cytometry. We used hamster testicular cells from the first spermatogenic wave to observe the consecutive appearance of the differen
Female hamsters were allowed to attack a series of target hamsters until they reached a criterion of attack satiation. Following delays of 0, 24, or 48 hr they were then presented with a novel "probe" target. Attacks on the probe target were reduced to 26% of baseline at 0 delay and had returned to
DNA-staining of hamster testis cell suspensions followed by flow cytometry demonstrated appearance of the first haploid cells at 23 days post partum (dpp) and of condensed chromatin (in elongated spermatids and spermatozoa) at 33-34 dpp. Mature spermatozoa were first observed in the caput epididymis
