 note = {Background: Infertility treatments (IFT) have been employed for couples having difficulty conceiving. Previous studies indicated that IFT result in the increased rates of the following conditions：multiple pregnancy, low-birth weight infants, preterm delivery, fetal growth restriction (FGR), and congenital anomalies. All these conditions increase infant morbidity. However, there are few studies examined the data from a single large neonatal intensive care unit (NICU) over a significant time period.
Objectives: We attempt to determine the impact of IFT on NICU practice. We retrieved all data of 3,913 infants admitted to Jichi Medical University Hospital NICU for 11 years, then assessed the clinical features and various morbidities of infants.
Results: Infants from IFT were approximately 10% of all admissions to NICU. We found a considerable amount of FGR in singletons from IFT, as well as CS, in pregnancies following IFT. 
Conclusion: There are increasing numbers of infants from IFT, and perinatal intensive care is indispensable for them.},
