Part I discusses human sperm chromatin structure and nuclear architecture, while part II presents laboratory evaluation of sperm DNA damage, including SCSA, SCD, TUNEL and Comet assays, and cytochemical tests. Biological and clinical factors in the etiology of sperm DNA damage are discussed in part III, including oxidative stress, abortive apoptosis, cancer, and environmental and lifestyle factors. Part IV presents clinical studies on the utility of sperm DNA damage tests, both with natural and ART-assisted pregnancies, and debates the clinical utility of such tests.  Real Fourdimensionalism: An Essay in the Ontology of Persistence and Mind (3,).

The Sperm Chromatin Structure Assay (SCSA) serves as a tool for measuring clinically important properties of sperm nuclear chromatin integrity. The assay utilizes the metachromatic features of Acridine Orange (AO), a DNA probe, and the principles of flow cytometry (FCM). SCSA data are not well correlated with classical sperm quality parameters and have been solidly shown to predict sub/infertility. This assay is ideally suited to human and animal fertility clinics to assess male sperm DNA integrity as related to fertility potential and embryo development as well as effects of reproductive toxi.

Author information.  Raw semen/sperm aliquots or purified sperm can be flash frozen, placed in a box with dry ice and shipped by overnight courier to an experienced SCSA(®) lab. The samples are individually thawed, prepared, and analyzed in ∼10 min. Of significance, data on 5, individual sperm are recorded on a 1, × 1, dot plot of green (native DNA) and red (broken DNA) fluorescence. Repeat measurements have virtually identical dot plot patterns demonstrating that the low pH treatment that opens up the DNA strands at the sites of breaks and staining by acridine orange (AO) are highly precise and repeatabl. Sperm chromatin structure evaluation is an independent measure of sperm quality that provides good diagnostic and prognostic capabilities. Therefore, it may be consid-ered a reliable predictor of a couple’s inability to become pregnant,8 and may also have an impact on the offspring, resulting in infertility  We also provide the rationale and the different. methodologies employed for sperm chromatin assessment. Human sperm chromatin structure. The nuclear status of sperm cells is determined by two major events that occur during spermiogenesis: acquisition of the final nuclear shape and the replacement of somatic-type histones by protamines (sperm-specific basic nuclear proteins) leading to highly packaged chromatin. This test uses special stains and complex instrumentation (flow cytometer), and a laser beam to quantitate the percentage of sperm with intact vs. fragmented chromatin (DNA). Thousands of sperm are analyzed, producing plots like the example below. This plot compares a sperm sample from a fertile individual with a patient/couple experiencing 16 miscarriages.

Data obtained from the sperm chromatin structure essay (SCSA) on fresh sperm was highly correlated with measurements of aliquots of the same sample collected over 44 wk, frozen, and then measured on the same day. Sperm head morphology and sperm chromatin structure remained abnormal at 44 wk for the mg/kg TEM dosage, suggesting that the abnormalities, present long after the initial toxic response, may be a result of mutation. This study demonstrates that flow cytometry provides a unique, rapid, and efficient means to measure effects of reproductive toxins and potential mutagens.
