Regarding blood types, what everyone knows should be four types: A, B, AB, and O. These four blood types are the most basic, but in addition to them, there are also special blood types, RH positive and RH negative, which are relatively rare. Some people may be particularly curious about whether these two blood types can have children. So which two blood types cannot have children?
Which two blood types cannot have children
In fact, there are no two blood types that cannot have children. As long as both husband and wife are in good health and cannot be consanguineous, they can have children. It's just that some fetuses may experience hemolysis after birth. The occurrence of hemolytic disease of the newborn is mainly caused by Rh blood type incompatibility and ABO blood type incompatibility between the mother and the fetus, and the blood type of the fetus is determined by both parents.
If the blood type antigen inherited by the fetus from the father is not present in the mother, the fetal red blood cells enter the mother's body and cause the mother to produce corresponding antibodies. These antibodies then enter the fetus through the placenta, leading to an immune response between the antigen and antibody, resulting in hemolysis. However, the probability of hemolysis occurring in the first pregnancy is relatively low. Of course, intramuscular injection of Rh immunoglobulin within 72 hours of birth can prevent Rh hemolysis in the next pregnancy.
Is it really impossible for couples with incompatible blood types to have children
Blood type incompatibility is common, but hemolytic disease in fetuses is rare. There are two types of blood type incompatibility between spouses: ABO blood type and Rh blood type. ABO blood type incompatibility refers to the situation where a woman with blood type O marries a man with blood types A, B, or AB, resulting in a fetus that can be classified as A, B, or O. If the fetus is of type A or type B, it will cause rejection reactions in the mother, leading to hemolysis and possible miscarriage and stillbirth.
But generally couples don't need to be too nervous, because even if the fetus inherits the father's blood type and the mother infant blood type is incompatible, it is rare for the fetus or newborn to actually develop hemolytic disease. Approximately 20-25% of pregnancies result in ABO blood type incompatibility, but only 2-2.5% experience fetal or neonatal hemolysis.
In our daily lives, some common blood types are not a problem, but if rare panda blood appears, it should be taken seriously. So women must undergo strict examinations before pregnancy, and if they are already pregnant, they should also go to the hospital regularly for relevant tests. Because this is the only way to regularly check whether the baby in the belly is healthy.
