For some reason it seems that maybe this isn't part of God's plan.

5 children in Michigan are now infected with a lifelong bone marrow disease, because they all have the same father. They were all conceived from the same sperm donor.

With stories like this, why is it so hard for people to understand that children deserve to be born to parents who know their spouses well enough to know if they are healthy. If we always try to cut corners, we will eventually get into trouble.
