When we see the embryological culture of eggs, of embryos in embryological laboratory, we can see that we receive egg for example Monday and normally blastocyst should be Saturday but sometimes we have blastocysts even Friday but sometime we have even Sunday and next Monday so, three, four day of difference. We can have during the embryo development so, it is right that with PCOS, the ovulation happens several times during this cycle and also probably the two, three follicles during this stimulation.
