why do pple with iud's get preggo?

[Ummy]

Hello,

I saw some posts about getting pregnant with an IUD, I know no BC is 100% effective but what causes one to get preggo with an IUD, is it b/c the iud is not in place correctly, or is faulty, etC? What are some of the reasons?

Just curious

Because the IUD is not made to stop conception from taking place. It's main purpose is to irritate the uterus in such a manner that when conception does take place that the fertilized egg can't implant. It doesn't do anything to stop ovulation from taking place. Some people theorize that it slows down sperm or speeds up the egg moving along so that they can't meet up, but they don't really know for sure and can't say how it would do this.

The stats they quote for failure are generally for perfect usage with no room for human error. If the IUD is not put in place correctly, comes lose, etc... it would certainly raise the failure rate.

Nooo!!!

I had one for years after DD and was always paranoid about this! The ones out on the market nowadays are so much better than the ones of the 70s and 80s, but my mom can tell stories (she works in healthcare industry) about babies being born with IUDs embedded in there bodies because the mom didnt want to risk mc after pg confirmation. Freaky!

However, if the Mirena is the one you are speaking about- it works by releasing a tiny dose of Progestin into the uterine wall, which thins it out to the point that the egg cant emplant...very similar to a traditional IUD. I also think the failures would come due to a misplaced IUD or a MIGHTY egg!

sometimes the IUD slips out of place with out the woman noticing - that's why it's important to check your strings. The IUD can be expelled from the uterus, or become imbedded in the wall of the uterus/migrate outside the uterus into the body.

This always confused me about Mirena. What is the point of adding the hormone? I know that non-hormonal IUDs are still on the market, and supposedly they are much better than the non-homonals of yesteryear.

My impression was that by adding Progestin, there is extra assurance against pregnancy because the hormone could even work to stop ovulation or fertilization, much like the traditional birth control pill. So is does the Progestin serve ONLY a contra-implantative purpose? :

[texaspeach]

it works like the mini pill and/or depo provera, but thickening the cervical mucous to make it inhospitable to sperm, and sometimes by preventing ovulation, but also by thinning the uterine lining so a fertilized egg can't implant.

They also think now that the copper in a copper IUD works as a kind of spermicide, making it very difficult for sperm to reach an egg to fertilize it. the copper theoretically also makes the uterus inhospitable to a fertilized egg so it won't implant.

I have an iud and had to have surgery last year and they saw the IUD. The doc said it wasn't in place and I needed to get it removed and reinserted or whatever. I didn't want to because I've had the same one for 3 years and haven't been pregnant yet. (I'm married and TTC next year so it wouldn't be that bad if I got pregnant anyway.)

Moral of the story is -- I've never been pregnant so for all I know my husband in infertile or something .. but I know mine's out of place and I'm still not pregnant.
