I have seen rarely poor oocyte which has a spesific anomally that has large halo at the periphery. As an embryologist, I made 5 day culture and there is no blastocyst occurence and resulted canceling the ICSI cycle. I am wondering the prognose of this kind of oocytes.
Here is some details;
29 years of woman,third ICSI trial, first two trial were at different good quality laboratories.
Woman Day 3 FSH: 9
E2 : 55
Man: Normal Sperm parameters
Antagonist protocol starting 150 IU rFSH up to day8. At day 4 gnrh antagonist started for 6 days up to day 9.At day 9, 75 IU rFSH and Decapeptyle injected. 35 hours later we collected 8 oocytes( 7 MII, 1 GV). 3 hours after oocyte pickup ICSI made and 5 of them fertilised and cultered 5 days but no blastocyst occured and cycle canceled.
Here is the oocyte and day 5 pictures.
I 'll be very appreciated for your helps,
