Child death may occur in the marriage between

a) Rh⁺ man and Rh^– woman

b) Rh⁺ man and Rh⁺ woman

c) Rh^– man and Rh^– woman

d) Rh^– man and Rh⁺ woman

(Rh factor was discovered by Karl Landsteiner. A child of Rh+ man will be Rh+ whether the mother is Rh+ or Rh–.

If the mother is Rh+ then there will be no problem but if the mother is Rh– so when the blood of the Rh+ child (in the womb) mixes with the blood of Rh– mother then some antibodies in the mother’s blood are formed against Rh+ factor which coagulates the womb blood causing death.

If birth takes place then there is a possibility of child death in the early years. This is known as erythroblastosis fetal. In most cases, the first pregnancy may succeed but after that, it fails.)
