We all know that humans have four blood types, namely A blood, B blood, O blood, and AB blood. However, each person's blood type is determined by the blood type of their father and mother, rather than being random. However, the combination of some blood types may cause problems for the fetus. So, are there risks of pregnancy for blood types O and AB?
Is pregnancy dangerous with blood types O and AB
If the mother is type O and the father is type AB, then the child should have type A or B blood, and the mother's blood contains antibodies against type A and type B blood, which may cause hemolytic reactions in the fetus. Generally speaking, children born to people with AB and O blood types after marriage have a 60% chance of hemolysis, which means their skin is particularly yellow and looks like jaundice hepatitis, but it can generally be cured now. Therefore, pregnancy with blood types O and AB is not dangerous and can be achieved.
Is it difficult for women with blood type O to have boys
In fact, gender is determined by chromosomes, with females having X+X chromosomes and males having X+Y chromosomes. This means that both males and females contribute one chromosome each for fertilization, with females contributing X and males having both X and Y. If it happens to be with X, then it's a girl; if it happens to be with Y, then it's a boy. Therefore, giving birth to boys or girls is not related to the blood type of the female or male partner. Giving birth to boys or girls mainly depends on the male partner, and the probability is 50%. The female partner's blood type O is not difficult to give birth to boys, and the probability is the same.
Although the combination of some blood types may cause some illnesses in the next generation, generally speaking, these can be cured, and parents don't need to worry too much. In addition, the editor suggests that young couples can go to the hospital for a check-up before preparing for pregnancy to determine if their physical condition is suitable for pregnancy.
