Sperm DNA Fragmentation Among Smokers and Non-Smokers as Measured by Sperm Chromatin Dispersion Test [PDF]

, 2018
Introduction: Traditionally, seminal fluid analysis is done to assess male infertility particularly sperm concentration, morphology and motility. Sperm chromatin dispersion test explores the quality of the sperm DNA structures.

SPERM DNA FRAGMENTATION, AGE AND MALE INFERTILITY [PDF]

, 2018
The aging process in the male reproductive system may include changes in testicular tissue, sperm production, and the like. Unlike females, males do not experience a substantial, rapid change (which occurs over a few months) until they grow older ...

Association between semen microbiome disorder and sperm DNA damage

Microbiology Spectrum
DNA fragmentation index (DFI), a new biomarker to diagnose male infertility, is closely associated with poor reproductive outcomes. Previous research reported that seminal microbiome correlated with sperm DNA integrity, suggesting that the microbiome may

Relationship between sperm progressive motility and DNA integrity in fertile and infertile men

Middle East Fertility Society Journal, 2018
Background: Progressive sperm motility was found to be predictive for in vitro and in vivo fertilization. There has been an increase in the literature of studies investigating whether DNA fragmentation could be associated with other semen parameters ...

Guidelines on sperm DNA fragmentation testing [PDF]

Translational Andrology and Urology, 2017
Male factor subfertility is present in more than 50% of the couples treated with assisted reproductive techniques. Routine semen analysis provides information on semen volume as well as sperm concentration, motility, and morphology. Standardized methods have been published by the World Health Organization (WHO) (1).

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Acridine Orange and Flow Cytometry: Which Is Better to Measure the Effect of Varicocele on Sperm DNA Integrity?

Advances in Urology, 2015
We evaluated the effect of varicocelectomy on semen parameters and levels of sperm DNA damage in infertile men. A total of 75 infertile men with varicocele and 40 fertile men (controls) were included in this study.

Sperm chromatin dispersion test before sperm preparation is predictive of clinical pregnancy in cases of unexplained infertility treated with intra-uterine insemination and induction with clomiphene citrate

Frontiers in Medicine, 2016
Background/Aims: A large proportion of men with normal sperm results as analyzed using conventional techniques have fragmented DNA in their spermatozoa.
