title: Influence of midluteal serum prolactin on outcome of pregnancy after IVF-ET: a preliminary study.
abstract: OBJECTIVE
  To investigate the relationship between serum prolactin levels in the midluteal phase and the prognosis of pregnancy after IVF-ET.
  
  
  METHODS
  
  
  
  METHODS
  Prospective study;
  
  
  METHODS
  Shimane Medical University Hospital;
  
  
  METHODS
  29 patients completing their 34th IVF cycle; and
  
  
  METHODS
  Serum levels of prolactin, estradiol-17 beta, and progesterone in the midluteal phase.
  
  
  RESULTS
  Midluteal prolactin levels were significantly lower in patients with early pregnancy loss than in the successful pregnancy group. The mean progesterone/prolactin ratio and the estradiol-17 beta/prolactin ratio were highest in patients with early pregnancy loss and were lowest in patients with successful pregnancies.
  
  
  CONCLUSIONS
  Findings of this study suggest that measurement of the serum prolactin concentration in the midluteal phase is useful for predicting the outcome of IVF-ET.
