Abstract
To determine a the correlation between follicular sizes oocyte maturity normal fertilization rate cleavage and embryo quality and b to establish whether oocytes recovered with or without follicular flushing have different developmental competenceAlmost all 99 of the oocytes recovered from follicles of group C were in metaphase II as opposed to 80 in group A and 81 in group B p 001 Overall there was a progressive and significant increase in fertilization rates from group A follicles to group C 47 vs 67 p 005 Overall 53 of oocytes retrieved from group A follicles showed either no fertilization or abnormal fertilization versus 27 in group C p 005 The oocyte recovery rate with follicular flushing improved from group A to group B and to group C follicles 65 vs 49 vs37 respectively p 001 There were no differences in rates of immature oocyte fertilization abnormal or not fertilization and cleavageThe results of this study shows that a Follicles larger than 18 mm at retrieval have consistently mature oocytes with a higher rate of fertilization b Small size follicles are still capable of containing mature oocytes but their rate of abnormal or no fertilization is high c Oocytes recovered with flushing are still able to produce embryos with full developmental competence
