title: Gonadotropin-releasing hormone agonist reduces the miscarriage rate for pregnancies achieved in women with polycystic ovarian syndrome.
abstract: OBJECTIVE
  To compare the effect of treatment with gonadotropin-releasing hormone agonist (GnRH-a) and human menopausal gonadotropins (hMG) with that of gonadotropins only, on the cumulative livebirth rate and miscarriage rate of pregnancies achieved in women with polycystic ovarian syndrome (PCOS).
  
  
  METHODS
  Retrospective analysis of the outcome of 97 pregnancies according to the treatment protocol, with or without GnRH-a. Calculation of miscarriage rate and cumulative livebirth rate by life-table analysis.
  
  
  METHODS
  Infertility clinic and in vitro fertilization (IVF) unit.
  
  
  METHODS
  Women with polycystic ovaries (n = 239) who were clomiphene citrate failures and received either GnRH-a/hMG (n = 110) or gonadotropins only (n = 129) for ovulation induction (n = 138) or superovulation for IVF (n = 101).
  
  
  METHODS
  For ovulation induction, hMG was given in a step-up, individually adjusted dose scheme. For IVF, three ampules of pure follicle-stimulating hormone were given for 3 days followed by three ampules per day hMG and then individual dose adjustment. Gonadotropin-releasing hormone agonist (Decapeptyl, D-Trp6, microcapsules, 3.75 mg) was given in a single dose 2 weeks before gonadotropin treatment.
  
  
  METHODS
  The rate of early miscarriages (< 12 weeks) per pregnancies achieved was analyzed, and the cumulative livebirth rate for each treatment group was calculated by life-table analysis.
  
  
  RESULTS
  Miscarriage rates after treatment in ovulation induction with (16.7%) and without GnRH-a (39.4%) and in IVF with (18.2%) and without GnRH-a (38.5%) were almost identical and were therefore analyzed together. Of pregnancies achieved with GnRH-a, 17.6% miscarried compared with 39.1% of those achieved with gonadotropins alone. Cumulative livebirth rate after four cycles for GnRH-a was 64% compared with 26% for gonadotropins only.
  
  
  CONCLUSIONS
  Cotreatment with GnRH-a/hMG for anovulatory women with PCOS reduces the miscarriage rate and improves the livebirth rate compared with treatment with gonadotropins alone.
