What are the health risks in the marriage between O+ and O- partners?
There are no health risks at all for the husband or wife.
You only need to be concerned if its the wife that is O-, and then only when she is pregnant.
Simple Answer: If a mother that has Negative blood is pregnant with a baby that has Positive blood, then there is a chance for her to miscarry. However with modern medicine she just needs to take a certain medication from the doctor during her pregnancy and there will be no problem. Prenatal care and not ignoring the start of a pregnancy are key to a health baby!
