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

Reproductive Biomedicine Online, 2018 Conventional semen analyses have limitations in male infertility diagnosis and prognosis. Assessment of sperm DNA fragmentation (sDF) has been proposed to discriminate fertile from infertile men and predict FSH treatment response in infertile men ...

Progress in Research on Sperm DNA Fragmentation [PDF]
Medical Science Monitor, 2020 With the increasing incidence of male infertility, routine detection of semen is insufficient to accurately assess male fertility. Infertile men, who have lower odds of conceiving naturally, exhibit high levels of sperm DNA fragmentation (SDF). The mechanisms driving SDF include abnormal spermatogenesis, oxidative stress damage, and abnormal sperm ...

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.

Sperm DNA and detection of DNA fragmentations in sperm [PDF]
Türk Üroloji Dergisi/Turkish Journal of Urology, 2018 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 perspective on sperm DNA fragmentation [PDF]
Translational Andrology and Urology, 2017 The paper on sperm DNA fragmentation by Ashok Agarwal et al . summarizes the currently available DNA fragmentation tests and discusses the role of sperm function tests in the intracytoplasmic sperm injection (ICSI) era (1). The authors have summarized the clinical utility of sperm DNA fragmentation test and have provided recommendations based on ...

Turkish journal of urology, 2022 Objective: Infertility affects about 15% of couples in reproductive age worldwide. Male factors are the main causes for this condition. Antioxidants have long been used for infertility treatment as they are easily available with a low cost.

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.
