Thank you friends for responding ..

My body is SO unpredictable, my first three stim cycle's where at
300, 300 & 350 iui had 16/15/11 eggs - could not get past day 2
Move to new clinic
4th cycle 400 iui - 23 eggs (3 blasts) excellent quality (2 tfd 1 frozen )
5th cycle 450 iui (isci) 25 eggs, 17 inseminated (7 fert) never icsi again, my eggs hated it, fragmented, poor quality

What did I do the cycle I had great quality ? I was prob more vigilent with tablets etc

The drop off rate for me (egg wise) is quite normally high, so I worry if I get 6 eggs at epu, I wont get to transfer...
