Please let me know your opinions

Hello all. My first IVF has been cancelled due to the low follicle count. I had 4 follicles, 2 were mature. I'm 41, husband is 44.

We tried 5 unsuccessfull IUI's before and my DR just switched my first IVF to IUI again. It will be my 6th IUI. He says he didn't want to lose the eggs and skip the cycle.

When I ask, we already have 5 failed IUI, he says it's all about luck. It can be happen this time too. I have DOR. Maybe 4 follicle will be my best. I had 4-5 when I was on Clomid for all failed IUI's.

I heard some doctors do egg retrival two times to collect more eggs. Can you please share your opinions? Other than I have no issues, husband sperm is very good.

Thank you
