title: Successful pregnancies treated with pioglitazone in infertile patients with polycystic ovary syndrome.
abstract: OBJECTIVE
  To investigate the efficacy of pioglitazone on fecundity in infertile patients with polycystic ovary syndrome (PCOS) who are resistant to conventional ovulation induction such as clomiphene, dexamethasone, or metformin.
  
  
  METHODS
  A retrospective pilot study.
  
  
  METHODS
  Department of Obstetrics and Gynecology in a general hospital.
  
  
  METHODS
  Nine infertile women with PCOS.
  
  
  METHODS
  Pioglitazone, 15-30 mg/day, up to 32 weeks.
  
  
  METHODS
  Pregnancy rate.
  
  
  RESULTS
  Seven of nine women became pregnant at an average of 11.3 weeks of initiation of pioglitazone. Four of seven pregnant cases conceived after the first successful induction of ovulation with the initiation of pioglitazone, and two cases conceived after the second cycle. Three women have already delivered, and there is one ongoing pregnancy. The other three cases ended in miscarriage during the sixth or eighth week of pregnancy.
  
  
  CONCLUSIONS
  Pioglitazone may be effective in infertile patients with resistant PCOS.
