Measuring Sperm DNA Fragmentation and Clinical Outcomes of Medically Assisted Reproduction: A Systematic Review and Meta-Analysis.

PLoS ONE, 2016
Sperm DNA fragmentation has been associated with reduced fertilization rates, embryo quality, pregnancy rates and increased miscarriage rates. Various methods exist to test sperm DNA fragmentation such as the sperm chromatin structure assay (SCSA), the ...

Validation of a field based chromatin dispersion assay to assess sperm DNA fragmentation in the bottlenose dolphin (Tursiops truncatus)

, 2014
Over the last two decades, there have been significant advances in the use of assisted reproductive technology for genetic and reproductive management of captive dolphin populations, including evaluation of sperm DNA quality.

From pathophysiology to practice: addressing oxidative stress and sperm DNA fragmentation in Varicocele-affected subfertile men [PDF]

International Brazilian Journal of Urology
Varicocele can reduce male fertility potential through various oxidative stress mechanisms. Excessive production of reactive oxygen species may overwhelm the sperm's defenses against oxidative stress, damaging the sperm chromatin. Sperm DNA fragmentation,

The Comparison of HA Binding and Zeta Methods Efficiency in Selection of Sperm with Normal Morphology and Intact Chromatin

مجله دانشکده پزشکی اصفهان, 2009
Background: Sperm selection for ICSI is based on morphology and motility, but these parameters may not relevant chromatin integrity. One of the sperm selection methods for ICSI is based on sperm functional characteristics.

Sperm DNA fragmentation in boars is delayed or abolished by using sperm extenders

, 2006
The semen quality of seven young adult boars was assessed for percentages of sperm motility, normal acrosomes, abnormal sperm, cells positive to sHOST (short Hipoosmotic Swelling Test), HPNA cells (sHOST Positive with Normal Acrosome cells) and the ...
