Sperm DNA can be damaged during sperm production and transport. Examen research shows that over 90% of recurrent miscarriage patients tested had sperm DNA damage above the levels found in couples who went on to have a healthy baby. This was true for couples who conceived naturally as well as those whose conceived with fertility treatment.
