Objective:
Establish the number of metaphase II oocytes that are needed for optimum blastulation rate and to achieve a better rate of gestation.
Methods:
Retrospective study. Women diagnosed with infertility. There were 110 women submitted to IVF/ICSI, excluding third day transfers and those with canceled cycles. After controlled ovarian stimulation, cultivation continued to blastocysts.
Results:
Average age of the patients: 33.41. IVF technique: 73 patients, 66.4%; ICSI: 37 patients, 33.6%. Pregnancy: gestation: 57.3%; Non-gestation: 42.7%. Mean number of oocytes in metaphase II: 7.5.
Conclusion:
The gestation rate coincides with the center's results (50-60%), reached with 7 mature oocytes. Mean blastulation rate was 39.2%.
