Birth abnormalities due to fertility treatment

I have previously answered the question if fertility treatments work.

I think that there is some more information that should make you rethink assisted reproductive techniques (ART). A study by Jennita Reefhuis shows that kids born through IUI and IVF are 2-4 times more likely to have birth defects like heart problems, cleft lip, cleft palate and abnormalities in the esophagus or rectum.

Obviously there are several caveats but the major takeaway from this is to let Nature do its magic, try not to have a baby during advanced maternal age, and there are plenty of kids waiting to be adopted.
