Jaan, when you say increased the quality do you mean the morphology? Also, according to the WHO criteria one only needs 4% morphology to be in normal range, why is this criteria used if it should be higher in reality? Does anyone know?
That's been my question too. I think there are a few possibilities.
1. They think 4% the threshold of normal, but of course you don't really want to be at the threshold, you want to be higher.
2. For clinics, it's all about success rates because they are for-profit. This is why a lot of clinics will push IVF if you have 4% (or maybe even 5%) because repeatedly doing IUIs and failing does not help their statistics. You can also be really cynical and just assume that they say 4% is bad because their profit on IVF is so much greater than with IUI or clomid or whatever else you do.
3. Different REs just have their own preferences. You'll see that all the time on these boards....for example, how big does a follicle need to be before triggering? How thick should the lining be for implantation to be possible? How many follicles will they let you have before a cycle is cancelled? What's the sperm threshold (number, morphology) before they think you need IUI or ICSI. It all really depends on your own doctor and your own clinic - you just have to find one that fits for you.
