“…These methods are based on the ability of some stains to test the conformation of sperm chromatin, which in turn depends on DNA strand breaks and DNA interaction with proteins (8, 9). The idea to test sperm chromatin with acridine orange (AO) after DNA denaturation occurred in the 1960s (10–12). In conjunction with flow cytometry, this method is known as sperm chromatin structure assay (SCSA) (13).…”

“…Defects in the binding of nuclear protein to DNA, which probably occur during the process of chromatin aggregation in spermateliosis, have only recently been incriminated in the formation of certain misshapen sperm heads (Gledhill, Dar\l=z%o\ynkiewicz & Ringertz, 1971). Their possible r\l=o^\lein an instance of infertility was noted earlier (Gledhill, Gledhill, Rigler & Ringertz, 1966a).…”

“…Existem evidências de que este processo de condensação do DNA possa ser parcial, resultando no complexo DNAproteína menos estável e aumentando a susceptibilidade à desnaturação 15 . Há ainda sugestão de que esta alteração possa ser causada por defeito na ligação entre os grupos fosfatos do DNA às proteínas nucleares ou por ocorrência de tipo anormal ou desconhecidos de proteína ligada ao DNA 15,16 .…”
