Male Infertility and Sperm DNA Fragmentation [PDF]

open access: yesOpen Access Macedonian Journal of Medical Sciences, 2018
BACKGROUND: One of the main factors affecting male infertility is DNA fragmentation in sperm. Male infertility is a heterogeneous group of disorders, known causes account for only 30-50%, and unknown cause (idiopathic) constitute the rest. Infertility involves nearly 15% of couples in the reproductive age, and only the male problem involves about 40 ...

A cost for high levels of sperm competition in rodents: Increased sperm DNA fragmentation [PDF]

open access: yes, 2016
Spermcompetition, a prevalent evolutionary process inwhich the spermatozoa of two or more males compete for the fertilization of the same ovum, leads to morphological and physiological adaptations, including increases in energetic metabolism that may ...

Associations of sperm DNA fragmentation with lifestyle factors and semen parameters of Saudi men and its impact on ICSI outcome

open access: yesReproductive Biology and Endocrinology, 2018
Background Male factor infertility is quite common as 30–50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility.

Assessment of sperm DNA fragmentation in stallion (Equus caballus) and donkey (Equus asinus) using the sperm chromatin dispersion test [PDF]

open access: yes, 2009
Sperm DNA fragmentation (sDF) is an important parameter to assessing sperm quality. Information about sperm quality is not available for donkeys, especially in some breeds at risk of extinction.

Effects of Sperm DNA Fragmentation on Semen Parameters and ICSI Outcome Determined by an Improved SCD Test, Halosperm [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2010
Background Sperm DNA fragmentation is known as an important cause of male infertility. The influence of sperm DNA damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial.

Sperm DNA and detection of DNA fragmentations in sperm [PDF]

open access: yesUrology Research and Practice, 2019
Abstract The questionable effectiveness of routine sperm parameters in determining male factor infertility problems and increasing the success rates of assisted reproductive techniques have led to the investigation of more detailed sperm parameters that could affect the male fertility and reproduction.

A guide to sperm DNA fragmentation testing [PDF]

open access: yesTranslational Andrology and Urology, 2017
A conundrum exists in the field of male infertility as in many other areas of medical study. It is described by the adage that advises one to not order a test or exam if you don’t know what to do with the results. The urologists’ conundrum is: how to use the information we have learned about abnormalities in sperm chromatin, specifically DNA ...

Dynamics of sperm DNA fragmentation in domestic animals - II. The stallion [PDF]

open access: yes, 2007
The mixed success of equine artificial insemination programs using chilled and frozen-thawed semen is most likely associated with the variable response of the sperm cell to the preservation process and the fact that stallions are not selected on the ...
