[Risk factors for early miscarriage among intrauterine singleton pregnancies after treatment with in vitro fertilization/intracytoplasmic sperm injection].

ABSTRACT

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 (P<0.05).
 CONCLUSION: Miscarriage after treatment with IVF/ICSI is affected by multiple factors. Women at elder age (>30 years old), women with a history of miscarriage or men with higher sperm DFI (≥15%) are the risk.
