In such cases, a cycle of in vitro fertilization is indicated, followed by preimplantation genetic test IVF-PGT by aneuploidy screening, in order to transfer only euploid embryos. The doctor never mentioned that there could be Sperm DNA Fragmentation caused by his diabetes, and I don't think that was tested at all. In my view fertility specialists have also been slow to recommend the DNA fragmentation test to patients about to undergo assisted conception treatments. Green fluorescence in turn shows the percentage of mature undamaged sperm The SpermComet test is different to the semen analysis test that we usually carry out.
Sperm DNA Fragmentation Test
Thus a high level of DNA damage in sperm cells may represent a cause of male infertility that conventional examinations cannot detect. The DNA in sperm is protected from damage by wrapping itself tightly around proteins inside the sperm head. Badly damaged sperm DNA is linked to problems including taking a long time to get pregnant or having a miscarriage.
