My wife and I have been trying to conceive for over a year, and my recent reports showed some concerns regarding sperm quality. I've heard about DNA fragmentation tests, but I'm confused about what numbers are actually considered 'normal' or healthy for a successful pregnancy? ~ Murugan Murthy, 38 Yrs
A sperm DNA fragmentation index (DFI) of 15% or less is considered normal. DFI values between 15% and 30% are regarded as moderate or average, while values above 30% are considered high and may significantly impact fertility. It is advisable to consult a fertility expert for interpretation and next steps. Starting a ninety-day cycle of targeted antioxidants can often improve your sperm quality by protecting the genetic material from the daily stress that leads to fragmentation.
