A rapid diagnostic method for double-strand breaks (DSBs), Sperm deoxyribonucleic acid (DNA) Fragmentation (SDF) Releasing Assay (SDFR).
By Pooja Toshniwal PahariaNov 7 2023Reviewed by Lily Ramsey, LLM In a recent study published in Scientific Reports, researchers developed a rapid diagnostic method for double-strand breaks , Sperm deoxyribonucleic acid Fragmentation Releasing Assay . They also explored the association between sperm DNA double-stranded breaks and reproductive outcomes.
The neutral comet test, which correlates with DSBs in clinical settings, has been used to examine DSBs; however, due to its technique sensitivity and absence of a consistent grading system, its clinical applicability is restricted. Further research is required to increase its clinical use. Sperm Chromatin Dispersion experiments utilizing bright-field microscopes were used to determine the total DNA fragmentation index . A medium to large halo denoted intact sperm DNA, whereas a small to negligible halo denoted fragmented DNA.
Further, the researchers conducted a retrospective investigation of 140 couples with at least two embryos under preimplantation genetic testing for aneuploidy . Based on the worldwide genetic testing community consensus, embryonic aneuploidy was determined based on mosaicism levels exceeding 80%; biopsied blastocyst counts ascertained the aneuploidy rates.
R11 DFI rose when treatment duration and dosages were increased using dose- and time-dependent Alu I and DNase I treatment. However, after H2O2 treatment, the R11 DNA fragmentation index remained unaltered, demonstrating that R11 could selectively identify sperm DSBs.
