Gary found this article today and forwarded it to me. It may answer some of the questions some of you have asked or were too afraid to ask. It is informational in that it does explain what infertility means and how some of the procedures are performed.

There are many people suffering silently with infertility. I do not agree with everything this organization supports, but I do value the emphasis they are placing on infertility and trying to raise awareness for an often overlooked part of many peoples' lives.
