ABSTRACT
The safety of ICSl as a novel procedure of assisted fertilization may be assessed by the health of the baby born. In order to evaluate the safety of ICSI, perinatal outcome and congenital anomaly of the babies born after ICSI were compared with those of babies born after IVF (control group). We analysed the clinical data from the obstetric and pediatric records, including the information obtained through telephone. The results are as follows; Mean gestaional age (+/-SEM) and birth weight in singleton pregnancy were 38.8+/-1.9 weeks and 3209.7+/-501.9gm in IVF group, 39.0+/-2.2 weeks and 3289.9+/-479.5gm in ICSI group, respectively. Mean gestational age and birth weight in twins were 36.8+/-2.1 weeks and 2512.8+/-468.0gm in IVF group, 36.5+/-2.8 weeks and 2492.7+/-537.1gm in ICSI group. In IVF group, perinatal mortality rates were 8.5 in singletons and 56.6 in twinst for the ICSI singletons and ICSI twins, the perinatal mortality rates were 11.6 and 49.0, respectively. The incidence of congenital malformations was 3.6% (8/224) in IVF group and 2.1% (4/188) in ICSI group, there was no statistical difference (p>0.05, Fisher's exact test). The incidence of major congenital anomalies was 0.9% (2/224; pulmonary artery hypoplasia, renal cystic dysplasia) in IVF group and 1.1% (2/188; holoprosencephaly, Cri du chat syndrome) in ICSI groups (p>0.05, Fisher's exact test). Similarly, there was no significant difference in incidence of minor congenital anormalies 2.7% (6/224) in IVF group and 1.1% (2/188) in ICSI group respectively (p>0.05, Fisher's exact test). In conclusion, there was no difference in the perinatal outcome and the incidence of congenital anomalies between the babies born after ICSI and those after conventional IVF.
