title: Human chorionic gonadotropin supplementation in recurring pregnancy loss: a controlled trial.
abstract: OBJECTIVE
  To investigate the efficacy of hCG in the management of recurrent early pregnancy loss.
  
  
  METHODS
  A prospective, randomized, controlled trial.
  
  
  METHODS
  Miscarriage Clinic, Women's Hospital, Liverpool, United Kingdom.
  
  
  METHODS
  Eighty-one women attending the miscarriage clinic with idiopathic recurrent pregnancy loss were randomized to receive hCG supplementation or placebo in early pregnancy.
  
  
  METHODS
  The success rate or live birth rate.
  
  
  RESULTS
  In women with regular menstrual cycles it was found that hCG had no beneficial effect, the pregnancy success rate being 86% in both groups. However, women with oligomenorrhea had a pregnancy success rate of 40% in the placebo group but a statistically significant improvement to 86% if hCG was given.
  
  
  CONCLUSIONS
  Human chorionic gonadotropin can be recommended for idiopathic recurrent pregnancy loss in women with oligomenorrhea.
