Objective: The aim of the study was to evaluate microdose flare-up Gonadotropin-Releasing Hormone (GnRH) agonist protocol and GnRH antagonist protocol with respect to their effects on in-vitro fertilization (IVF) results in patients with poor ovarian response according to the Bologna Criteria. Material Methods: This was a retrospective cohort study conducted in the Assisted Reproduction clinic of University of Health Sciences, Etlik Zübeyde Hanım Gynaecology Training and Research Hospital. A total of 645 patients who had been diagnosed as poor responders in our clinic, between 2007 and 2018, and received treatment with either microdose flare-up GnRH agonist protocol (n=250, 38.8%) or GnRH antagonist protocol (n=395, 61.2%), were included in the study. Results: The mean age of the study group was 34.5±5.5 years. Comparisons showed that IVF cycle cancellation frequency (p<0.01), third day estradiol level (p=0.04) and third day follicle stimulating hormone level (p<0.01) were significantly greater in patients who underwent the microdose flare-up protocol. In the GnRH antagonist group, the number of surviving children (p=0.01), antral follicle count (p<0.01), follicle count on day of human chorionic gonadotropin (hCG) administration (p<0.01), endometrial thickness on hCG day (p<0.01), number of oocytes collected (p<0.01), mature oocyte count (p<0.01), embryo transfer number (p<0.01) were higher compared to the microdose flare-up protocol group. The two groups were similar in terms of clinical pregnancy rate. Conclusions: In terms of clinical pregnancy rate, the IVF results of microdose flare-up and GnRH antagonist protocols are similar. Further studies are needed to reach more comprehensive results on the subject.

Objective. To compare the effectiveness of a flexible multidose gonadotropin-releasing hormone (GnRH) antagonist against the effectiveness of a microdose flare-up GnRH agonist combined with a flexible multidose GnRH antagonist protocol in poor responders to in vitro fertilization (IVF).Study Design. A retrospective study in Akdeniz University, Faculty of Medicine, Department of Obstetrics and Gynecology, IVF Center, for 131 poor responders in the intracytoplasmic sperm injection-embryo transfer (ICSI-ET) program between January 2006 and November 2012. The groups were compared to the patients’ characteristics, controlled ovarian stimulation (COH) results, and laboratory results.Results. Combination protocol was applied to 46 patients (group 1), and a single protocol was applied to 85 patients (group 2). In group 1, the duration of the treatment was longer and the dose of FSH was higher. The cycle cancellation rate was significantly higher in group 2 (26.1% versus 38.8%). A significant difference was not observed with respect to the number and quality of oocytes and embryos or to the number of embryos transferred. There were no statistically significant differences in the hCG positivity (9.5% versus 9.4%) or the clinical pregnancy rates (7.1% versus 10.6%).Conclusion. The combination protocol does not provide additional efficacy.
