I am 30 years old. I am planning to get married to a girl who is known to me. We have very good understanding. But, we have the same blood group that is O positive. Since blood group is a factor for having babies, do you think having same positive blood group could create problems for future generation? My father is very concerned about this. He talked with several doctors and they ensured that it could create problem. And they do not want me to marry this girl. I talked with another doctor, she replied me like it is not a big problem.
I am in great trouble right now, how could I give clear explanation to my father about this issue. My father told me he knows two couples of same positive blood group who has been married for 10 years without having baby. And doctors could not find any problems for both men and women. But their blood immune system did not match to have a baby.
I have these questions:
One thing to clarify to clarify is that we are two brothers and two sisters and all the six members of my family have same blood group O positive. My elder sister got baby after 8 years and her husband is B positive. And my younger sister, she always gets sick since her antibody of her blood cell might not strong enough to fight disease.
My father explained, due to my parents have same blood group; my sisters might got those above explained problems. I will explain my family based on your explanation.
Thank you in advance.
Welcome to icliniq.com. Based on your query, my opinion is as follows:
There are two major blood group systems and more than 400 minor blood group systems.
The major blood group systems are ABO system and Rhesus system, which are important. In the ABO system, there is A, B, AB and O. While in Rhesus, if it is present, it is positive and if not then negative.
If the girl is not a relative then blood group is hardly a concern. If both are O positive, it would not matter.
If she is a relative, get genetic tests to rule out any common diseases, which can affect the future kid. This test is called as genetic counseling. Only among close relatives, the immune system behaves dangerously due to reduced genetic pool.
To conclude, having a common blood group is not a problem. She can donate blood to you and you to her in emergencies just like your siblings can. No other complications with same blood group.
If necessary in case of second or third-degree relative then genetic counsellingRegarding follow up:
