Rhesus Factor is an antigen that exists on the surface of red blood cells in most people (about 85% of humans). It is also referred to as Rh Factor. People who have the Rh factor have “positive” (+) blood types, such as A+, O+ or B+ while those who do not have the Rh factor have “negative” (-) blood types, such as A–, O– or AB– . The “+” and “-” in front of the blood group is the Rhesus factor. Generally, we have A+, A–, B+, B–, AB+, AB–, O+ and O–. Rhesus factor is genetic in nature. It is inherited from the parents, emphatically the father.
How does Rhesus Factor cause miscarriage?
If a Rh– woman is impregnated by a man with Rh–, there wouldn’t be any problem. However, if a Rh– woman is impregnated by a man with Rh+, there would be a problem. We have here what is medically called Rhesus Factor Incompatibility. The baby would obviously be Rh+. During child birth, baby inherits their Rh+ from the father. Once the baby’s Rh+ comes in contact with the woman Rh- during delivery, the antibodies are immediately activated by the woman’s body’s immune system.
The activated antibodies would see the new Rh+ as foreign body or a threat and consequently they would be at alert to attack and get rid of the foreign body. Unfortunately as such, after this particular child birth, the woman would keep having miscarriages because the activated antibodies would see subsequent Rh+ pregnancies as foreign bodies and would keep fighting and taking them off.
Women with Rh activated antibodies are said to be Rh sensitized and once these antibodies are activated , they can never be deactivated until the woman dies. Rh induced antibodies are activated in a Rh- woman by child birth, abortion, miscarriage and ectopic pregnancy.
If a Rh– woman commits an abortion for a Rh+ man and the antibodies are activated in her system, the woman might end up childless throughout her life except if she later marries another man with with the same Rh–. The possibility of a Rh– woman finding a Rh– man is slim as about 85% of human beings are Rh+. This is a warning to our young girls who commits abortions all in the name of boyfriend-girlfriend relationships.
