    Abstract:
    OBJECTIVE: To investigate pregnancy outcome of infertility women with polycystic ovary syndrome (PCOS) treated by in vitro maturation (IVM) of immature oocytes. METHODS: From Nov. 2003 to Oct. 2007, medical documents of 118 women with PCOS underwent 140 IVM treatment cycles in Reproductive Medical Center of First Affiliated Hospital of Wenzhou Medical College were collected. Follow up of 62 pregnancies were performed by prenatal examination in hospital or telephone query to record perinatal monitoring and pregnancy outcome. RESULTS: There are 62 pregnant women including 5 biochemical pregnancies and 57 clinical pregnancies obtained in 140 transferred cycles, resulting in the pregnancy rate of 40.7% (57/140). The rates of singleton pregnancies, twin pregnancies and triplet pregnancies were 61.4% (35/57), 29.8% (17/57) and 5.3% (3/57), respectively. The rate of ectopic pregnancy was 3.5% (2/57). Seven (7/57, 12.3%) women underwent early abortion during 7 -14 weeks of pregnancy, and 1 case (1/57, 1.75%) with premature rupture of membranes occurred at 22 gestational week. One woman with twin pregnancy spontaneously reduced to singleton at 8 gestational weeks. Totally, the rate of pregnancy complications was 26.3% (15/57) including premature rupture of membranes (1 case), placenta previa (1 case), hypertensive disorder (1 case), preterm delivery (10 cases) and gestational diabetes mellitus (2 cases). Until now 47 women gave birth to 65 infants including 29 singleton infants and 18 twins. One female preterm neonate died after 6 days' delivery due to pneumonia, no malformation was observed on the other neonates. 21.3% (10/47) of deliveries were premature,76.6% (36/47) of deliveries were full-term, 2.1% (1/47) of deliveries were postterm. The mean birth weight was 2972 gram. The rate of infants with low weight was 26.2% (17/65). CONCLUSIONS: A relatively high clinical pregnancy rate has been achieved, the rates of early abortion, ectopic pregnancy, pregnancy complications, perinatal mortality, and neonatal malformation occurring after the treatment of IVM in women with PCOS are not mounting. However, the relative high rates of multiple pregnancies, low birth weight and preterm labor were increased.
