OBJECTIVE: To examine the association between morphologic characteristics of oocytes and i) women’s age, ii) type of stimulation protocol, iii) duration of ovarian stimulation iii) serum E2 levels, iv) fertilization rate, v) PN scoring. DESIGN: All patients who underwent IVF treatment between January 1st and April 25th 2007 were included. MATERIALS AND METHODS: After evaluation of morphologic criteria listed in Table I; these characteristics were classified according to women’s age, stimulation protocol, duration of ovarian stimulation, serum E2 levels on the day of hCG administration, fertilization rates and PN scores. Pearson chi-square test or Likelihood Ratio chi-square test were used. RESULTS: From 153 cycles, 1586 oocytes were retrieved. 1380 of these oocytes were MII oocytes. 603 MII oocytes were classified as normal. Rest of it contained one or more anomalies. Statistical meaningful results were summarised at Table 1. CONCLUSIONS: We demonstrate which might cause an increase at certain abnormalities in oocyte structure and which anomalies are associated with low fertilization rate.
