DNA Fragmentation Index
The DNA Fragmentation Index (DFI) is a measure of sperm DNA quality, indicating how much of the sperm’s DNA is damaged. Sperm DNA is stored in the head of the sperm cell, and when the DNA strands break or fragment, it can affect fertilization and embryo development. A higher DFI is associated with lower fertility rates and a higher risk of miscarriage, even when other sperm parameters like count and motility are normal.
1. What is DNA Fragmentation Index (DFI)?
DFI measures the quality of sperm DNA by showing how much is damaged or fragmented.
2. Why is sperm DNA quality important?
Damaged sperm DNA can lower fertility, affect embryo development, and increase miscarriage risk.
3. Does a high DFI affect fertility even with normal sperm count?
Yes, a high DFI can reduce fertility, even if sperm count and motility are normal.
4. What does a high DFI result mean?
A high DFI percentage indicates more sperm DNA damage and potential fertility issues.
5. What treatments are suggested for high DFI?
Treatments like ICSI or advanced fertility techniques are often recommended.
6. How does the DFI test help with infertility?
It identifies hidden sperm DNA issues that may impact fertility, guiding better treatments.
7. Can lifestyle changes improve DFI results?
Yes, adopting a healthy lifestyle can reduce sperm DNA damage over time.
