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.
Experts think it is unlikely. If having type O blood really does reduce your fertility, then this should apply irrespective of your age.
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).
Most of the time, being Rh-negative has no risks. But during pregnancy, being Rh-negative can be a problem if your baby is Rh-positive. If your blood and your baby's blood mix, your body will start to make antibodies that can damage your baby's red blood cells. This is known as Rh sensitization.
Rh Incompatibility in Pregnancy
Problems can occur when the mother is Rh- and the baby is Rh+. This mismatch in blood type is often referred to as Rh incompatibility.
Excessive use of O-negative leads to a shortage of blood supply compared to other types of blood. Individuals with O-negative blood generally have higher levels of stomach acid and are more likely to be exposed to medical conditions such as ulcers.
In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.
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.
O negative blood is missing both the A antigen and the B antigen and does not contain the protein for Rh positive blood. This means that it's missing those things that could cause a bad reaction during a blood transfusion and can be given to any blood type.
Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood.
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.
Theoretically yes, but it would be extremely rare. Two O parents will get an O child nearly all of the time. But as with anything in biology, there are occasional exceptions to this rule.
In fact, according to the experts, most children who are O-negative have parents who are O-positive.
Why is O negative blood important? O negative blood is often called the 'universal blood type' because people of any blood type can receive it. This makes it vitally important in an emergency or when a patient's blood type is unknown.
O negative is the most common blood type used for transfusions when the blood type is unknown. This is why it is used most often in cases of trauma, emergency, surgery and any situation where blood type is unknown. O negative is the universal blood type. O negative blood type can only receive O negative 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).
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it's called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
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.
Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor). So, there are eight possible blood types: O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.
The survival curve in group B was worse than that in groups A, O, and AB. These findings suggest that in our patient population, blood group B is not a marker for longevity but may be a marker for earlier death.

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.
If two parents both have type O blood, all their children will have type O blood.
