title: Is there any effect of oocyte count retrieved in the OPU procedure on pregnancy outcomes?
abstract: We aimed to investigate whether the number of oocytes retrieved during ovum pick-up has any effect on pregnancy outcomes when using the gonadotropin-releasing hormone or GnRH long agonist or antagonist protocols. A retrospective study was conducted between 2012 and 2014. The patients were grouped according to the number of oocytes retrieved at ovum pick-up; < 10 oocytes (Group 1), 10-14 oocytes (Group 2) and ≥ 15 oocytes (Group 3). Biochemical pregnancy rates were compared among the three groups. Statistical analysis was performed using one-way ANOVA test for continuous variables and chi-square test for categorical variables. In total, 825 treatment cycles were included in the study. Groups 1, 2 and 3 consisted of 514, 206 and 105 patients, respectively. There was no difference among the three groups regarding biochemical pregnancy rates (22.8%, 28.6% and 28.6%; p = 0.166, respectively). The results of our study suggest that the number of eggs retrieved has no effect on pregnancy outcome in assisted reproductive technology treatment.
