To determine whether high DNA stainability (HDS), as assessed by the sperm chromatin structure assay (SCSA), predicts the risk of early miscarriage after in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI). Retrospective cohort study of consecutive pregnancies after IVF and ICSI treatment. Reproductive medicine center. A total of 1,602 pregnancies after 832 IVF and 770 ICSI treatments. HDS measured using SCSA. Early miscarriage (≤12 weeks). The HDS represents the proportion of immature spermatozoa lacking the normal exchange of histone for protamine-complexed DNA, and the outcome parameter was early miscarriage (≤12 weeks). For all treatments, the odds ratio (OR) and 95% confidence interval (CI) for early miscarriage was 1.41 (1.07-1.85) if HDS >15% compared with HDS ≤15%. When comparing the two HDS categories, for ICSI, the OR was 1.44 (1.01-2.04) whereas for IVF the results were not statistically significant. There is a small but increased risk of early miscarriage if HDS >15% compared with HDS ≤15%. This increased risk is seen only after ICSI, not after IVF. These findings suggest that HDS can be used as a predictor of an increased risk of miscarriage in ICSI treatments.
