title: [Pregnancy outcomes following pulsatile GnRH treatment: results of a large multicenter retrospective study].
abstract: OBJECTIVE
  The aim of the present study was to evaluate the efficacy of pulsatile GnRH treatment in a large French cohort of patients with hypogonadotropic hypogonadism.
  
  
  METHODS
  A retrospective study involving all women treated with pulsatile GnRH, over a 3-year period, in 24 French centers. Pregnancy rate and pregnancy outcome were the criteria for evaluation.
  
  
  RESULTS
  The study included 248 women who received a total of 829 treatment cycles. The treatment routes of administration were subcutaneous (56.1% of the patients), intravenous (31.1%), or both (12.7%). The pregnancy rate per treatment cycle was 25%, while the mean number of cycles needed to obtain a pregnancy was 2.8+/-1.7. The miscarriage rate was 8.2% and the multiple pregnancy rates 8.8%. The mean delivery term was 38.4+/-2.4 weeks and the mean birth weight was 3009+/-561 g. No severe ovarian hyperstimulation was recorded. Ovarian cysts occurred in 2.3% of the treatment cycles, local allergies in 1.7%.
  
  
  CONCLUSIONS
  Our study has shown that pulsatile GnRH treatment was well tolerated, without severe hyperstimulation. It induced a good pregnancy rate with favorable pregnancy outcomes.
