Abstract

This retrospective cohort study aimed to analyse the risk of congenital anomalies (CAs) in infants conceived by infertile women through assisted reproductive technology (ART). A total of 9,013 clinical pregnancy cycles resulting in 9,101 live births between 2004 and 2014 were analysed. Congenital anomalies were evaluated and compared with spontaneous pregnancies in infertile women. A total of 9,101 infants were born following ART. Three subgroups were established: In vitro fertilisation fresh embryo transfer (IVF‑ET), n=2,919, intracytoplasmic sperm injection fresh embryo transfer (ICSI), n=1,996 and frozen‑thawed embryo transfer (FET), n=4,186. No significant differences in perinatal outcomes were observed between the three subgroups. A total of 105 (1.15%) infants were born with CAs. The birth defect rate was slightly higher in the IVF‑ET subgroup compared with the other subgroups. Among infants in the IVF‑ET and ICSI‑ET subgroup, the probability of birth defects increased with increased maternal age (>35 years), male factors and diminished ovarian reserve. In the FET group, the risk of birth defects was significantly increased with multiple births and maternal age >35 years. The risk of congenital anomalies following ART was not significantly different compared with spontaneous conceptions within the infertile study population. The results of the present study may provide guidance for patients who are considering treatment for infertility in China.
