title: [Pregnancy outcomes of in vitro fertilization and embryo transfer in infertile women with polycystic ovarian syndrome].
abstract: OBJECTIVE
  To investigate the pregnancy outcomes of in vitro fertilization (IVF) and embryo transfer (ET) in infertile women with polycystic ovarian syndrome (PCOS).
  
  
  METHODS
  From August 2005 to June 2011, 200 IVF-ET cycles performed in women with polycystic ovarian syndrome in Shengjing Hospital and Shenyang 204 Hospital were enrolled in this retrospective study, matched with 400 IVF-ET cycles in infertile women with fallopian tube factors as control group. The incidence of abortion, gestational diabetes mellitus (GDM), hypertensive disorders in pregnancy, preterm birth, small for gestational age infant (SGA), large for gestational age infant (LGA), neonatal asphyxia, neonatal death and deformity was compared between two groups.
  
  
  RESULTS
  The incidence of spontaneous abortion was 26.0% (52/200) in PCOS group, which was significantly higher than 10.2% (41/400) in control group (P < 0.05). The incidence of GDM, hypertensive disorders in pregnancy, preterm birth, cesarean section in PCOS group was 23.6% (35/148), 16.2% (24/148), 17.6% (26/148), 83.1% (123/148), which were significantly higher than 4.2% (15/359), 6.1% (22/359), 7.8% (28/359), 73.8% (265/359) in control group (P < 0.05). The incidence of SGA, LGA, neonatal asphyxia, neonatal death and deformity did not show remarkable difference between two groups, which were 2.7% (4/148), 4.7% (7/148), 5.4% (8/148), 0 in PCOS group and 1.4% (5/359), 2.2% (8/359), 2.8% (10/359), 0 in control group (P > 0.05).
  
  
  CONCLUSIONS
  IVF-ET is an effective treatment for infertile women with PCOS, however, the incidence of spontaneous abortion, GDM, hypertensive disorders in pregnancy, preterm birth, cesarean section in PCOS patients was increased.
