Evaluation of chromatin condensation in human spermatozoa: a flow cytometric assay using acridine orange staining.
TL;DR: The use of swim-up and Percoll gradient centrifugation methods was shown to improve the percentage of spermatozoa with normal chromatin structure in some samples with poor initial quality.
Sperm analysis by flow cytometry using the fluorescent thiol labeling agent monobromobimane
TL;DR: FCM analysis of bimanelabeled spermatozoa offers a convenient method for the study of sperm thiol–disulfide status and permits detection of sperm subpopulations within an individual sample.

Investigation of epididymal sperm maturation in the golden hamster.
TL;DR: Staining with acridine orange indicated an increase in chromatin condensation in cauda epididymal spermatozoa, when compared to those obtained from the caput or corpus, and viability, measured by exclusion of the dye, was significantly less in spermatozosa from the cauda than from the proximal or mid-caput epidIDymis.

Epididymal maturation of chromatin in spermatozoa from control monkeys (Macaca fascicularis) and those treated with Cetrorelix, a gonadotropin-releasing hormone antagonist.
TL;DR: Eididymal chromatin condensation is normal in GnRH-antagonist-treated monkeys as long as sperm are being produced and can compensate for poor testis function so that spermatozoa with normal states of chromatin Condensation are found in the distal cauda epididymidis and probably the ejaculate.

Spermatogenesis in the golden hamster during the first spermatogenic wave: a flow cytometric analysis.
TL;DR: 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, indicating that RNA was lost during epididymal sperm maturation in this species.
