Methods: Two hundred thirty eight hCG-primed IVM cycles were performed in 213 patients with polycystic ovaries. If sibling mature oocytes were retrieved on day of collection, they were divided into two groups, Group 1 (n = 78): M-II oocytes obtained from follicles size 10-14mm; Group 2 (n = 192): M-II oocytes obtained from follicles size <10mm. Results: Of the 238 cycles, 63 cycles had more than one M-II oocytes retrieved (total M-II oocytes = 270) both from Groups 1 and 2. There were no significant differences between the two groups for oocyte diameter (117.2mm vs. 116.9mm), fertilization (79.5% vs. 72.4%) and good quality embryo on day 3 (66.1% vs. 56.8%). Conclusions: The M-II oocytes retrieved from the cohort of follicles (<10mm diameter) can produce the same quality of embryos as that from large follicles, likely contributing to improve the clinical outcome.
