My advice for those who are having fertility problems would be the following:
1. Talk about how far you are willing to go for infertility treatments PRIOR to attempting to conceive a child. Clear thinking and a plan is important.
2. Clearly indicate your beliefs to the IVF clinic and ensure that they understand that you do not wish to have embryos killed in this process. If they do not want to play ball, go somewhere else.
3. Prayerfully determine whether you want to go through all of this, or to adopt a child that needs a loving Christian home.
In addition, you may have noticed that I've added Imago Dei to the blogroll. Serge's thoughtful essays on bioethics make him a must-read. Plus I noticed that I was on his blogroll. (While I do not have a reciprocity policy, I do tend to check out blogs that link to me, and I'll add them if I like what I see.)
