title: Androgens and antimüllerian hormone in mothers with polycystic ovary syndrome and their newborns.
abstract: OBJECTIVE
  To explore the possible effect of metformin on maternal and fetal androgens and antimüllerian hormone (AMH) levels at birth and to study the predictors of maternal and fetal AMH levels.
  
  
  METHODS
  Substudy of a randomized controlled trial (the PregMet study).
  
  
  METHODS
  University hospital.
  
  
  METHODS
  Women with polycystic ovary syndrome (PCOS) and their newborns (n = 132).
  
  
  METHODS
  Metformin, 2,000 mg/daily, or placebo from the first trimester until delivery.
  
  
  METHODS
  Androgens and AMH levels in maternal venous serum and in umbilical vein and artery serum.
  
  
  RESULTS
  Except for the increased free testosterone index (FTI) in the umbilical artery in boys, metformin did not influence maternal or fetal androgens, or AMH levels. The maternal body mass index (BMI) was a negative and FTI a strong positive predictor of maternal AMH levels. Maternal androgens and AMH levels did not correlate to fetal gender. In girls, gestational age, birth weight, or maternal androgens did not correlate to the AMH levels. In boys, birth weight was negatively correlated to the AMH levels.
  
  
  CONCLUSIONS
  Except for FTI, which was higher in boys, metformin had no impact on maternal or fetal androgen levels or the level of AMH. Fetal AMH, as a surrogate marker for ovarian development, was unaffected by maternal androgens. Birth weight and gestational age had no impact on AMH levels in girls; in boys, AMH probably reflects the physiologic variations due to birth weight.
