The sperm chromatin structure assay. Relationship with alternate tests of semen quality and heterospermic performance of bulls
sperm chromatin structure assay alternate tests semen quality heterospermic performance
2009/2/23
Data obtained by the sperm chromatin structure assay (SCSA) on spermatozoa from nine bulls were correlated with fertility, measured by heterospermic performance (-0.94, P less than 0.01) and by al...
Effects of heat stress on mouse testicular cells and sperm chromatin structure
Testicular heat stress SCSA
2009/2/17
Scrotal regions of mice were exposed to a 38.0, 40.0, or 42.0 degrees C (+/-0.1) H2O bath for 60 minutes to determine the effects of elevated temperatures on testicular cells and sperm chromatin str...
Studies on sperm chromatin structure alterations and cytogenetic damage of mouse sperm following in vitro incubation. Studies on in vitro-incubated mouse sperm
sperm chromatin structure alterations cytogenetic damage of mouse sperm
2009/2/12
Mouse epididymal sperm incubated in Tyrode's T6 fertilization media were analyzed over time for chromosome damage by two methods. First, cytogenetic analysis was done on paternal pronuclei metapha...

2008/12/23
During the past decade, the sperm chromatin structure assay (SCSA) has become an important tool for assessing semen quality in the human andrology laboratory. The SCSA uses the metachromatic propert...
Cryopreservation of Ram Semen Facilitates Sperm DNA Damage: Relationship Between Sperm Andrological Parameters and the Sperm Chromatin Structure Assay
Artificial insemination semen quality motility chlortetracycline viability SCSA
