Something Weird

Because I like numbers and statistics and large sample sizes to compare, I often spend time that I shouldn't looking at the objective, government statistics on IVF and DE success rates.  The reason I think it's important is that as my colleague said this week, you want to go to the medical clinic that has the best batting average.

Here is the weird part.  I would assume that if a clinic has a really good DE success rate, they should also have a really good IVF success rate or vice versa.  However, the clinic I'm in love with in San Diego, while it has an over 80% success rate in DE (waaay higher than my local clinic).  However, it has a slightly lower success rate with regular IVF than the local clinic.  

Hmmmm.  In the process of writing that paragraph, I just answered my own question.  I know for a fact that the San Diego clinic doesn't turn down anyone whereas the local clinic has a reputation for not offering IVF to people whom they don't think it will work.  

That could explain the differences in regular IVF rates.  I still think the differences in DE rates have to do with lab skill and donor pool.

Well, dang.  I thought I'd found a real conundrum to blog about and really, I'm just wasting time.

You will usually find a variance in IVF success percentages in women under 30 vs. donor eggs.

And the logical question is, why? I mean, donor egg women are under 30 too.

But the difference is that IVF women under 30 already have infertility issues of some kind (could be PCOS, endometriosis, uterine issues, etc.) so their number is going to always be lower than the pool of donor eggs who are, presumably, women with no known fertility issues.

I thought it was bizarre at first but then it made more sense!
