When a woman is Rh negative and her fetus is Rh positive, it is called Rh incompatibility. Why is Rh incompatibility a problem? When the blood of an Rh-positive fetus gets into the bloodstream of an Rh-negative woman, her body will recognize that the Rh-positive blood is not hers.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive. Antibodies from an Rh negative mother may enter the blood stream of her unborn Rh positive infant, damaging the red blood cells (RBCs).
Fertility: a small study (544 women) performed did suggest that women with blood type O may be at a higher risk for what's called “diminished ovarian reserve.” More studies are needed in order to better understand this, so if you have blood type O, don't panic just yet.
The Rh-negative blood type can pose risks during pregnancy, including increasing the risk of miscarriage or stillbirth in the second or third trimester. Nowadays, women with a negative blood group are preventively given the Rho GAM injection, to reduce the risk involved.
For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.
A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.
Sometimes an incompatibility may happen when the mother is blood type O and the baby is either A or B. This can affect the newborn baby, who may need treatment after birth.
Blood Incompatibility
When the mother has type O blood and the baby has B blood type or A blood type (from the father), research has found that there's a 20 percent incompatibility rate which could result in newborn jaundice or a possible miscarriage.
Yes this is definitely possible.
Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
Usually, we don't have to worry about blood type when deciding to have a child. However, there are some exceptions. In particular, an Rh negative mother can sometimes have pregnancy complications - though doctors have an easy way to fix this issue!
You cannot receive type B or type AB blood. If you have type B blood, you can only receive type B or type O blood. You cannot receive type A or type AB blood. If you have type AB blood, you can receive all blood types.
Rh factor: Miscarriage can be caused because of the incompatibility of the mother's blood and the blood of the unborn foetus commonly known as Rh factor incompatibility. This type of miscarriage occur when the blood type of mother is Rh negative, and the foetus blood type is Rh positive.
But sometimes he or she may discover an untreated health problem, such as an autoimmune disease — where the mother's immune system attacks the embryo — a thyroid problem, a misshapen uterus or one of a few very rare disorders that can make your body reject pregnancies.
Experts think it is unlikely. If having type O blood really does reduce your fertility, then this should apply irrespective of your age.
If two parents both have type O blood, all their children will have type O blood.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
Over 80% of the population has a positive blood type and can receive O positive blood. That's another reason it's in such high demand. O positive donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.
Although O-positive people can donate blood to people with any positive blood type, they can only receive blood from O-positive and O-negative (O−) people. Research suggests that people with blood group O have a lower risk of heart diseases and memory problems (including dementia) than the rest of the population.
Couples who are both type Os will have children who are blood type O. Parents who are both type As can have children with blood type O. There are also subgroups within the blood types, such as Rh positive or negative, which need to be taken into account when looking at a potential blood type issue.
In most cases, an O parent and an AB parent will have only A or B kids. I added a table at the end of this answer that has all blood type combinations for two parents plus the possible blood types for their children. Exceptions to these rules are extremely rare. (Though not impossible.
Similarly for Rh factor inheritance, assuming you both were Rr, you have 25% chance for RH negative baby. To conclude.. its possible for a A+ and B+ couple to have O- baby. You are proud parents of a universal donor.
