Oxidative origin of sperm DNA fragmentation in the adult varicocele [PDF]

International Brazilian Journal of Urology, 2021
Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown.

Impaired semen quality, an increase of sperm morphological defects and DNA fragmentation associated with environmental pollution in urban population of young men from Western Siberia, Russia.

PLoS ONE, 2021
Poor sperm morphology and an elevated DNA fragmentation level are considered to be related to spermiogenesis malfunctions as a result of genetic mutations and effects of environmental factors, including industrial pollution.

SPERM DNA FRAGMENTATION [PDF]

Archives of Andrology, 2006
Several techniques have been developed to measure the amount of sperm DNA damage in an effort to identify more objective parameters for evaluation of infertile men. The integrity of sperm DNA influences a couple's fertility and helps predict the chances of pregnancy and its successful outcome.

Correlation analysis of sperm DNA fragmentation index with semen parameters and the effect of sperm DFI on outcomes of ART

Scientific Reports, 2023
Routine semen analysis provides limited information about a man’s male reproductive potential and can not always fully explain male infertility. Many male infertilities are caused by sperm DNA defects that routine semen quality analyses fail to detect ...

Effects of cigarette smoking on semen quality, reproductive hormone levels, metabolic profile, zinc and sperm DNA fragmentation in men: results from a population-based study

Frontiers in Endocrinology, 2023
Background Cigarette smoking seems to have a negative impact on men’s reproductive health, but our knowledge of its effects on the reproductive function of Russian men is still very limited.

Understanding sperm DNA fragmentation [PDF]

Translational Andrology and Urology, 2017
We greatly value the commentary by Dr. Gosalvez on the “Clinical utility of sperm DNA fragmentation testing: practice recommendations based on clinical scenarios” by Agarwal et al. (1). The author initiated his well-written note with an overview of the structural and physiologic significance of sperm DNA on male reproduction addressing its ...

Sperm DNA fragmentation [PDF]

Translational Andrology and Urology, 2017
I agree with Agarwal et al. (1) that sperm DNA fragmentation (SDF) should be included in the evaluation of male factor infertility, along with semen analysis.

Sperm DNA Fragmentation and Sperm-Borne miRNAs: Molecular Biomarkers of Embryo Development?

International Journal of Molecular Sciences, 2023
The evaluation of morpho-functional sperm characteristics alone is not enough to explain infertility or to predict the outcome of Assisted Reproductive Technologies (ART): more sensitive diagnostic tools are needed in clinical practice.
