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 ...

Sperm DNA fragmentation: indication and uses [PDF]
Translational Andrology and Urology, 2017 If you really think about it, the microscopic portion of conventional sperm analysis relies on the same principles of light microscopy that have been present since Antony van Leeuwenhoek first saw sperm cells in the 17th century. Cell counts, motility, and cellular beauty (based on our idea of an ideal sperm) guide us on a daily basis.
