Alkaline and neutral Comet assay profiles of sperm DNA damage in clinical groups.
BACKGROUND The analysis of sperm DNA fragmentation has become a new marker to predict male infertility, and many techniques have been developed. The sperm Comet assay offers the possibility of differentiating single- and double-stranded DNA (ssDNA and dsDNA) breaks, which could have different effects on fertility. The objective of this study was to perform a descriptive characterization of diff...
متن کاملStudies on electron beam induced DNA damage and repair kinetics in lymphocytes by alkaline comet assay
Background: Exposure to ionizing radiation is known to induce oxidative stress followed by damage to critical biomolecules like lipids, proteins and DNA through radiolysis of cellular water. Since radiation has been widely used as an important tool in therapy of cancer, the detailed investigation regarding the DNA damage and repair kinetics would help to predict the radiation sensitivity of cel...
متن کاملHuman semen quality and sperm DNA damage assessed by comet assay in clinical groups.
BACKGROUND/AIM About 10%-15% of couples around the world suffer from infertility. Male infertility is responsible directly or indirectly in approximately 60% of cases. A deficiency in semen is the most common cause of male infertility. MATERIALS AND METHODS The study included 180 male subjects aged 18-50 years with 26 fertile and 154 infertile. The infertile subjects were further subdivided a...
متن کاملHuman semen cryopreservation: a sperm DNA fragmentation study with alkaline and neutral Comet assay.
Sperm cryopreservation is widely used for both research and reproduction purposes, but its effect on sperm DNA damage remains controversial. Sperm DNA fragmentation (SDF) has become an important biomarker to assess male infertility. In particular, the differentiation between single- and double-stranded DNA fragmentation (ssSDF and dsSDF) has clinical implications for male infertility where ssSD...
متن کاملSperm DNA damage output parameters measured by the alkaline Comet assay and their importance.
The alkaline Comet assay has shown high diagnostic value to determine male reproductive health and prognostic ability to predict ART success. Here, spermatozoon was analysed in 47 fertile donors and 238 patients, including 132 couples undergoing ART [semen was collected: Group I - within 3 months of their treatment (n = 79); and Group II - 3 months prior to their treatment (n = 53)]. We introdu...
