Codeine-induced sperm DNA damage is mediated predominantly by oxidative stress rather than apoptosis
Redox Report, 2020 Background: Opioids have been implicated to induce infertility. Although codeine remains the most used opioid for recreational purpose, no study has documented its effect on sperm quality.

TUNEL assay—Standardized method for testing sperm DNA fragmentation
, 2021 Sperm DNA integrity is important for normal functions such as fertilization, implantation, pregnancy and fetal development. Sperm DNA fragmentation (SDF) is more common in infertile men and may be responsible for poor reproductive function.

The Effect of Glyphosate on Human Sperm Motility and Sperm DNA Fragmentation [PDF]
International Journal of Environmental Research and Public Health, 2018 Glyphosate is the active ingredient of Roundup®, which is one of the most popular herbicides worldwide. Although many studies have focused on the reproductive toxicity of glyphosate or glyphosate-based herbicides, the majority of them have concluded that the effect of the specific herbicide is negligible, while only a few studies indicate the male ...

Correlation of sperm DNA damage with blastocyst formation: systematic review and meta-analysis
Middle East Fertility Society Journal, 2021 Background The routine semen analysis fails to detect sperm DNA damage which contributes to the majority of male factor infertility. Sperm DNA fragmentation test (DFI) measures the sperm DNA damage. Blastocyst formation is an important step in IVF ± ICSI.

Effect of season on the dynamics of cat sperm DNA fragmentation
BMC Veterinary Research, 2023 Background Feline species undergo reproductive seasonality; thus, sperm characteristics, such as DNA integrity, can be affected by the photoperiod. This study was conducted to determine the effect of seasonal changes on sperm quality and on the dynamics ...

Data from: A cost for high levels of sperm competition in rodents: increased sperm DNA fragmentation
, 2016 Sperm competition, a prevalent evolutionary process in which 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 ...
