You're not alone, and the answer may be in what wasn't tested. DNA fragmentation and oxidative stress don't show up on a standard semen analysis. But they can drive fertilization failure, embryo arrest, and poor blastocyst development. If the male side was cleared after the basic parameters were evaluated, it may not have been fully evaluated. In this episode, you'll learn: What a semen analysis actually measures and what it leaves out Why normal parameters don't always translate to embryo development How DNA fragmentation and oxidative stress affect fertilization and blastocyst outcomes The patterns we see in recurrent IVF failure when male factor hasn't been fully assessed Why embryo development is a shared biological process, not an egg quality issue I'm Sarah Clark, founder of Fab Fertile and host of Get Pregnant Naturally, a podcast with over 1 million downloads. My team works with couples navigating low AMH and failed IVF, reviewing functional lab results including gut microbiome, food sensitivity, vaginal microbiome, nutrigenomics, HTMA, DUTCH, toxin testing, and bloodwork, alongside nervous system work, to help identify patterns that may not have been considered. We work alongside your medical team, not instead of them. Not sure what's been fully evaluated? Download the free Embryo Audit Checklist to map your past cycles and labs so you can see what's been looked at and what may have been missed. Access it here Ready to go deeper?
