- W1981522045 abstract "ObjectiveThe purpose of this study was to compare the use of single dose gonadotropin releasing hormone (GnRH) antagonist (0.25 mg) versus coasting for the prevention of severe ovarian hyperstimulation syndrome (OHSS) in patients with high risk undergoing invitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).DesignRetrospective study.Materials and MethodsPatients undergoing IVF/ICSI with the long GnRH agonist protocol were identified as high responders based on the serum E2 level >3000 pg/ml and the multiple follicular development on the day of human chorionic gonadotropin (hCG) administration. Eighty six severely overstimulated IVF/ICSI patients with the long GnRH agonist protocol were enrolled the study and were consecutively assigned to either coasting group (Group A, n=42) and single dose GnRH antagonist (0.25 mg) treatment group (Group B, n=44). Patients treated with a single dose GnRH antagonist 0.25 mg on the day before hCG administration in group B. In group A, the duration of coasting prior to hCG administration was 2 days. Recombinant hCG 250 mcg was given to all patients when following a drop in serum E2 levels. Outcome measures included OHSS incidence rates and pregnancy rates in the two trial groups.ResultsEstradiol levels were decreased significantly both of the groups. There was no difference in the incidence of moderate and severe OHSS between the groups. One of the 42 patients in the coasted group developed severe OHSS and three developed moderate OHSS. In the single dose GnRH antagonist group, one of the 44 developed severe OHSS and four developed moderate OHSS.There were no significant differences between the two groups comparing serum E2 levels on the day of hCG administration, the number of oocytes retrieved, fertilization and pregnancy rates.ConclusionThe administration of single dose 0.25 mg GnRH antagonist appears to be an effective alternative to coasting for the prevention of OHSS in IVF patients who are at risk with high E2 levels in a GnRH long agonist protocol.
