PREDICTION OF OOCYTE OUTPUT: How can we maximize the oocyte retrieving from follicles in Controlled Ovarian Hyperstimulation cycles?
 Abstract
 Aim: We designed our study with the purpose of determining which variables should be used to predict oocyte output, to increase the number of collected oocytes and the success rate of IVF.
 Materials and Method: A total of 412 infertile patients admitted to the IVF center of a tertiary university hospital between the years 2016 and 2018 were evaluated retrospectively. The number of oocytes obtained by OPU from the follicles as the result of COH was grouped in percentiles. The variables effective on oocyte output were analyzed in the groups, and tests to predict acquisition of the maximal number of oocytes were tried to be determined. 
 Results: When we investigated according to the oocyte/≥ 14 mm follicle ratios, we determined that 10.2% of the patients were in the ≤ 30% group, whereas 4.1% of them were in the group of 31-40 %. 6.6% of the patients were in the group of 41-50 %, 2.9% in the group of 51-60%, 5.6% in the group of 61-70 %, 8% in the group of 71-80%, 4.9% in the group of 81-90 %, and 57.8% in the group of 91-100 %. According to the results of our study, the variables effective on the oocyte/≥14 mm follicle ratio were the patient’s age, basal FSH value (cutoff 9.5mIU/mL, sensitivity 0.706, specificity 0.621, p=0.001), basal LH (cutoff 5.5mIU/mL, sensitivity 0.640 specificity 0.690, p
