RESUMO
OBJECTIVE@#To investigate the risk factors associated with early miscarriage among intrauterine singleton pregnancies after treatment with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). @*METHODS@#A retrospective case-control study was performed on all singleton pregnancies underwent IVF/ICSI from January, 2013 to May, 2014, in Xiangya Hospital. Ninety-six early miscarriage patients served as a case group and 593 pregnancies with live birth served as a control group. We analyzed factors for early miscarriage after IVF/ICSI in two groups. @*RESULTS@#Multivariate logistic regression analysis demonstrated that the women age, miscarriage history, and sperm DAN fragmentation index (DFI) were the risk factors for early miscarriage (P30 years old), women with a history of miscarriage or men with higher sperm DFI (≥15%) are the risk.
