How do Dr.'s explain IUD's?
This is something I've been wondering about. Do they tell you that they basically prevent a fertilized egg from implanting? Which in actuality causes a miscarriage each month conception occurs?

Or do I understand it right?

Re: How do Dr.'s explain IUD's?
The IUD can work in a variety of ways actually.

For a copper IUD it works the following ways:
1. The IUD its self prevents implantation because it is an object in the uterus.
2. The copper thins the line of the uterus, making it difficult for a viable pregnancy to occur.
3. The copper actually can kill sperm and thicken mucus, causing no fertilization to occur.

So in many cases, fertilization *can* sometimes occur, and then the egg has nowhere to implant and is just expelled from the body.

With hormonal IUD's:
1. The IUD its self prevents implantation because it is an object in the uterus.
2. The hormonal properties can thicken mucus which makes it difficult for sperm to get to the egg at all
3. The hormones in the IUD usually prevent ovulation all together.

So really, in some cases, fertilization can occur but the IUD prevents the pregnancy from continuing/implanting.

Many doctors don't really talk about that a whole lot, because really, a lot less women would get the IUD if they knew that pregnancy was possible but would end up terminated because of the above reasons.
