Commentary: sperm DNA fragmentation testing in action [PDF]

Translational Andrology and Urology, 2017
The expert panel proposed a guideline on the clinical utility of sperm DNA fragmentation testing (1). Rapid advancement in the field of sperm DNA testing over the last two decades was summarized and structurally presented by the four clinical scenarios in an evidence-based approach.

Unraveling the sperm proteome and post-genomic pathways associated with sperm nuclear DNA fragmentation

, 2013
Sperm DNA fragmentation has been suggested as a marker for infertility diagnosis and prognosis. Hence, understanding its impact on male physiology and post-genomic pathways would be clinically important.

Effect of sperm cryopreservation and preparation before freezing–thawing process: A study of DNA fragmentation and ultrastructure

Journal of Advanced Pharmaceutical Technology & Research
Male fertility preservation can be achieved through assisted reproductive technology, in which sperm cryopreservation plays an essential role. However, the freezing–thawing process induces cellular stress, primarily through intracellular ice crystal ...

Sperm DNA fragmentation and its influence on mammalian reproduction

Sperm DNA fragmentation is a recognized factor in male infertility with direct implications for embryo development, implantation and pregnancy outcomes. Historically, standard semen analysis has not included assessments of DNA integrity, creating a clear

Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa [PDF]

, 2010
Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation.

Fragmentation index of DNA sperm in llama semen (Lama glama)

, 2017
DNA fragmentation of spermatozoa is an important indicator of seminal quality and fertility. The quality of the genetic information contained in the DNA molecule transmitted by the spermatozoa is important for the proper development of the embryo.
