DNA Fragmentation Index (DFI) is a specialized test that evaluates the integrity of sperm DNA, providing deeper insights into male fertility beyond standard semen analysis. High levels of DNA fragmentation in sperm can affect fertilization, embryo development, and increase the risk of miscarriage, even when conventional sperm parameters appear normal. DFI testing is particularly recommended for couples with unexplained infertility, recurrent IVF failures, or repeated pregnancy loss. At our fertility center, we use advanced methods to assess DFI accurately and guide personalized treatment strategies, including antioxidant therapy or ICSI. Understanding sperm DNA quality through DFI helps improve reproductive outcomes and treatment success
