Lining (what is good?), IUI stats & IVF success rates

A bunch of stuff I learned in random order:

Lining:
~ In general, 8-13 mm is good, less than 6 is potentially a problem, and greater than 15 or so could possibly reduce chances for a successful pregnancy.

IUI facts (taken from here):
~ It is usually recommended to do IUI just before ovulation is set to take place. Six hours is often the time frame given as washed sperm doesn’t live much beyond six to 12 hours.

~ However, if your infertility problems are caused by male factor, insemination is more likely to take place within six hours after ovulation.

~ Insemination using fertility drugs will take place 24 to 36 hours after you receive an hCG injection

~ It is normally recommended that a sperm count of at least 5 million be used. However, the less sperm that is used, the lower the chances of success. Therefore, a sperm count between 20 and 30 million is usually thought of as ideal.

~ Natural IUIs tend to have lower success rates, dipping down to about 6% in some cases.

~ IUIs done with fertility drugs that produce multiple eggs have success rates of up to 30% associated with them. Additionally, sperm count greatly affects the outcome with IUI. Using sperm samples with a smaller count often cause a couple to have less success. (really? Less sperm = less chance. Good lord, no shit.)

~ Overall, though, a success rate of 15% to 20% is associated with IUI.

IVF success rates for 2007 for ~my~ clinic (highlights from 2007 stats, just published):
~ Fresh embryos from non donor eggs:
under 35 = 79% (holy moly! what great success rates. Damn, wish I was under 35 yrs old!)
35-37 = 55%
38-40 = 40%
41-42 = 50%

~ Frozen embryos from non donor eggs:
under 35 = 56%
35-37 = 60%

~ Fresh Donor egg (donor age):
under 35 = 90%

~ Frozen Donor egg (donor age):
under 35 = 50%

Update: I wanted to point out that these are pregnancy rates, not live baby rates. Since this is from 2007, they haven't been able to collect the delivery rates yet, so this is all we have right now.

Thanks for the 'bunch of stuff', v interesting.

Thinking of you and wishing you loads of luck.

Thanks for the info - I had no idea that IUI success rates were so low!

My fingers are crossed for you this C!

Oh yeah, Brianna, I knew about IUI being really low success rates. It's because the IUI isn't taking much out of the "natural" equation. All it's doing is putting the sperm farther in at first. Other than that, it's all still normal chances. Blech!

The IVF stats look too good to be true... Perhaps that is pregnancy rate, including chemical pregnancies, and not take-home-baby rate?

nancy said...

Rachel - Yup. It's the "percentage of transfers resulting in pregnancies".

It's just the "highlights" that were published for 2007. Since it'll be Sept/Oct of 2008 to have all the "live birth" statistics, I simply don't have those to share yet :) We have to wait until all those pregnancies pan out.

You don't know me - i was a lurker on JSO and rarely ever posted there, but I read your blog often and I love all the info I find. I just wanted to say - I'm hoping this is your cycle and that you get everything you want!!!!

Io said...

Wow. Those are some crazy good ivf stats. Heres hoping you don't have to utilize their (great) ivf technique.

Denise said...

Those IVF success rates sure look good! Here's hoping you don't get to that point!
