DFI | Fertility | Per treatment success rate |
Below 15 | Normal | Normal success rate for IUI, IVF and ICSI IUI: approximately 20% IVF: approximately 30% ICSI: approximately 30% |
15 to 25 | Reduced | Success rate reduced for IUI and IVF IUI: approximately 12% IVF: approximately 18% ICSI: approximately 30% |
Above 25 | Strongly reduced | Success rate reduced for IUI, IVF and ICSI IUI: approximately 1 to 2% IVF: approximately 12% ICSI: approximately 18% |
Choose the most optimal fertility treatment.
The level of DFI can guide you to the most effective fertility treatment.
A low DFI implies that the sperm DNA is robust and that is unlikely to become damaged (fragmented) if the sperm has to swim a long way to the egg and fertilize this.
On the other hand, a high DFI means that the sperm DNA is very fragile and that it is ‘a race against the clock’ for the sperm to get into the egg and have any damage to the DNA repaired by the egg. In such cases, ICSI treatment is adviceable (perhaps combined with TESA).

Get the most out of the SDI® test
When the intercourse dose not result in a successful pregnancy, you should consider to take the SDI® test as early as possible. You can do this test at home before you even visit your doctor or a fertility clinic.

– Determine if DNA fragmentation is a problem for you
– Use the result to choose the most optimal fertility treatment
– Focus on factor which can improve male fertility
