Male fertility
DNA fragmentation testing estimates damage to sperm DNA, which is associated with lower fertilisation and higher miscarriage rates in some studies. It is not part of routine assessment in Australia; results rarely change treatment, and thresholds differ between tests. Discuss cost and what would change before paying for it.
Also known as: DFI, DNA fragmentation index, sperm DNA damage
