In My IVF cycle 14 eggs are shown in transveginal scan..after embryo collection dr say it's only 9 eggs are collected( ok fine)...at the time of Embryo transfer she says only 2eggs are good (grade 1)and others are not good..we see others are grade 2 bt they says thay can't frozen ...how is it possible that in 15 only 2 are good enough to make blastocyst.. sorry bt i lv doubt on that..is it normal ?
