Tks for sharing the link to the article..my hubby SA results are good..he has no issue..Your IUI is considered a natural one without any hormone jab like mine. My IUI is done on cd18 too. Our egg growth will definitely be slower than ladies who are using hormone jabs to simulate egg growth for IUI.
No woman is born with 100% good eggs. http://www.advancedfertility.com/age-eggs-chromosomes.htm All women are born with a mix of good and bad eggs at birth. It's by random which eggs get activated at each cycle. That's why iui and ivf are games of chances in a way.
The studies I mentioned is for ivf. The simulations of egg growth by hormones in iui and ivf are similar. But the eggs are extracted out and fertilized manually for ivf in a lab.
Besides egg quality, iui success also depends on sperm's morphology and motility? How were your hubby's sa?
I had to venture into ivf after my iui as my hubby has poor motility and morphology. I didn't even know whether his army managed to swim near my egg after iui before my egg said byebye in 24h.
My belief is if we persevere long enough, we will activate some good eggs for fertilization.
Failed 2 iui already, giving myself a break n might straight proceed to ivf..
We all just have to hang in there & hope at the end of it we can hold a baby in our arms..
