Because fertility decisions should be based on data you can trust. 🧬
Â
A “normal” semen analysis doesn’t always mean healthy s***m DNA.Â
That’s where DNA Fragmentation testing comes in.
And not all DFI tests are the same.
Â
TUNEL and COMET both evaluate s***m DNA damage — but they serve different purposes.
Â
COMET is highly sensitive and widely used in research settings.
TUNEL, on the other hand, is one of the most clinically validated methods, strongly linked with fertilization, embryo development, implantation, and miscarriage outcomes.
Â
At Fertilysis, we use the TUNEL assay because consistency matters.
When working with patients and clinics worldwide, we prioritize methods that provide:
✔️ reliable results
✔️ reproducible interpretation
✔️ strong clinical relevance
