Sperm Chromatin Structure Assay: Its Clinical Use for Detecting Sperm DNA Fragmentation in Male Infertility and Comparisons With Other Techniques
Open accessAbstract
The Sperm Chromatin Structure Assay (SCSA) was first described in the December 5, 1980 issue of Science (Evenson et al, 1980a).The data described in that article showed a significant difference between proven fertile and subfertility or infertility in men and bulls and the susceptibility to denaturation of their sperm nuclear DNA.A subsequent study (Evenson et al, 1984) described SCSA data obtained from men with testicular cancer.The data were heterogeneous, and begged the question, what was SCSA measuring?Great effort has been spent over the past 15 years on animal model systems, mostly related to dose-response toxicology experiments and large animal fertility trials.The results from these studies showed that SCSA was highly dose-responsive to toxicants, highly repeatable, and provided meaningful biological information on sperm nuclear DNA defects.The extensive data from nonhumans (Evenson et al, 1985(Evenson et al, , 1986(Evenson et al, , 1989a(Evenson et al, ,b, 1993a(Evenson et al, ,b,c, 1994(Evenson et al, , 1995b;; Ballachey et

“Recently, chromatin decondensation and DNA fragmentation have been claimed as new markers of sperm immaturity and malfunctioning, and it has been suggested that these evaluations are included alongside the conventional semen analysis (Evenson et al., 2002; Lefièvre et al., 2007; Tosti and Fortunato, 2011; Zini, 2011;…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
