IVF statistic question

suntoto · January 2010

I was having a great chat with one of my IRL friends who has gone through 4 IVF cycles and 3 IUI cycles with all BFNs. She told me that on average it takes 3 IVF cycles to achieve a pregnancy. Has anyone else ever heard of this? What would it take for IUIs?

TIA.

Totally untrue as far as IVFs.

That's not true. I just had a long discussion with my RE about this yesterday.

There are stats out there for general success rates for each procedure, but they vary WIDELY. It really depends on the individual and the clinic. I think we all know people who've gotten pregnant on their first IUI or IVF (or first time trying for that matter!) and those who are setting the curve on the other side, but I think ~50% for IVF and ~20% for IUI are some stats that I've heard.

Nationwide, across all age groups and diagnoses, the IVF success rate is about 30%. I do not know the exact mathmatical "average" for the number of tries it takes to get pg with IVF. However, if you look at the mathmatical formula, [(1*0.3) + ((1-0.3)*0.3) + (1-0.3-0.21)*0.3)] you can see that after three tries, only about 65.7% of women doing IVF will be pregnant.

ETA ---> and due to the nature of the formula, the absoulte total increase in % success rate diminishes with each successive attempt.

So not true.

That makes a lot of sense. Thanks for this info!

Not true that I've ever heard..

I thought I'd heard something like 'If it doesn't work in the first three tries, your chances go down'. But maybe I'm thinking of clomid or something.
