The most common cause for miscarriage is a chromosomal defect with the fetus. It is believed that up to 70% of miscarriages are caused by this reason. This does not mean there is something wrong with the parents' ability to produce a child. Rather, there was something wrong with that one particular egg or sperm that caused the embryo to not develop or implant properly.

Are there any other causes of miscarriage aside from chromosomal defect?
