The world is slowly waking up to giving people an option to pick a partner amongst the large group of those who are blood type compatible. One of the most important reasons to know a future partner´s blood type is that the rhesus factor can decide whether or not there may be potential complications on the horizon when picking someone you plan to have children with.
See the article below highlighting the section about blood type compatibility:
New Delhi: Gone are the days when matching of horoscope intended to be the right practice for a successful marriage. These days, what doctors and medical experts are recommending is checking the medical compatibility of bridegroom.
Various young couples go for the medical compatibility tests as experts truly believe that watching the physical and medical health is more essential than matching kundalis.
The tests to check the medical compatibility include tests of Hepatitis B, Hepatitis C, knowledge of the blood groups, Thalassemia, sexually transmitted diseases, HIV and Tests for certain known Genetically Transmitted Diseases.
This is to mention here that the trend has been accepted by Indian couples and has now turned out to be a part of selection process in arrange marriages. Wedding therapists believe that even in love marriages people opt for the medical compatibility tests.
Here are the tests that need to be done under the medical compatibility of a couple before taking the plunge-
Blood Group Tests: When it comes to blood groups it is essential that you both have the same Rhesus factor (Rh factor). If your blood group is O positive and your partner has a blood group of B negative, he or she has a negative Rh factor. This information is essential especially during pregnancy, as a mother and baby of opposite Rh factors could lead to severe complications and even death of the baby.
Tests for genetically transmitted conditions: The test is important to check if you or your partner carries any genes that could manifest as a disease in your children. This includes conditions like thalassemia (a genetic blood disorder where a baby cannot produce enough red blood cells and will need a blood transfusion very often), cancers, juvenile diabetes, mental disorders, etc.
Tests for sexually transmitted diseases: There might a certain stigma attached to this test, but it is best that you both know your health status when it concerns these diseases. While HIV is life threatening, other STDs like hepatitis C, herpes, gonorrhoea, etc. are something you will have to live with all your life; not to mention the risk of your child getting affected by it.

Objective: To assess the relationships among ABO group, factor VIII (FVIII), and incident cognitive impairment in a large, prospective cohort study of black and white adults in the United States using a nested case-control design.
AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types. Previous studies have shown that people with type O blood have a lower risk of heart disease and stroke, factors that can increase the risk of memory loss and dementia.
Methods: Incident cognitive impairment was defined using cognitive domain tests over a mean follow-up of 3.4 years. ABO blood group was measured by genotyping in a nested case-control sample of 495 cases with cognitive impairment and 587 controls.
Results: Those with blood group AB and those with higher FVIII had an increased risk of cognitive impairment, adjusting for age, race, region, and sex (respective odds ratios 1.82, 95% confidence interval [CI] 1.15–2.90; and 1.24, 95% CI 1.10–1.38 for 40 IU/dL higher FVIII). Mean FVIII was higher in those with blood type AB (142 IU/dL; 95% CI 119–165) compared with O (104 IU/dL; 95% CI 101–107), and FVIII mediated 18% of the association between AB group and incident cognitive impairment (95% CI for mediation −30% to 68%).

Marriages worldwide are following the same trend: people are getting married later – or not at all. But while following the same trends, marriage still looks very different across the globe.
The above map uses data from the UN to show the average age at which people get married by country. Since the UN draws its data from different surveys done on a country by country basis, the data is not always from the same year.1
The biggest differentiator of marriage age seems to be a country’s income, with people in developed countries marrying later. Nordic countries and Western Europe rank among the highest for mean age at marriage at above 30 years. Afghanistan has one of the lowest at 20.2 years.
Averaging the marriage age of entire populations hides the fact that men get married much later than women. This is true in every country. The gender age gap for marriage is wider in less developed countries: women get married 8.3 years earlier in Afghanistan to 1.8 years in France, for example. As we see in the below graph of worldwide averages of mean age of marriage, the gap has narrowed only slightly over the past 35 years.

It remains common today for women to marry very young in some developing countries. Thirty nine countries have data showing that 20% of women married by age 18. In twenty countries, a full 10% of women married by age 15. In only 2 countries, however, are 10% of men married before the age of 18. Still, men and women are getting married later in every region of the world. The average age of marriage for women increased from 21.8 to 24.7 years from the seventies to the mid 2000s, with the average age for men rising a comparable amount.
This has resulted in some fairly dramatic stats here in the United States. Today, less than half of American adults are married – down from 72% in 1960 – and almost as many babies are born out of wedlock as to married couples.
Nevertheless, around the world the majority of people still get married, even if they get married later. In all but a dozen or so countries, 80% of men and women have been married by age 49, and even more people commit to comparable or similar “consensual unions.” Despite all the global differences and changes, shacking up is still the norm.
If not, you may suffer from this:
Some messages need to be repeated. And this is one.
But little do many know in regards to the WHY:
If you are blood type O, you are more likely to be a secretor than other ABOs.
By secretor it indicates that you carry your blood cells in your saliva and sweat.
That means mosquitoes can smell and sense you.
This is just one of many reasons why knowing your blood type is so important.
These links between blood types and diseases have a mysterious arbitrariness about them, and scientists have only begun to work out the reasons behind some of them. For example, Kevin Kain of the University of Toronto and his colleagues have been investigating why people with type O are better protected against severe malaria than people with other blood types. His studies indicate that immune cells have an easier job of recognising infected blood cells if they’re type O rather than other blood types.
More puzzling are the links between blood types and diseases that have nothing to do with the blood. Take norovirus. This nasty pathogen is the bane of cruise ships, as it can rage through hundreds of passengers, causing violent vomiting and diarrhoea. It does so by invading cells lining the intestines, leaving blood cells untouched. Nevertheless, people’s blood type influences the risk that they will be infected by a particular strain of norovirus.
The solution to this particular mystery can be found in the fact that blood cells are not the only cells to produce blood type antigens. They are also produced by cells in blood vessel walls, the airway, skin and hair. Many people even secrete blood type antigens in their saliva. Noroviruses make us sick by grabbing onto the blood type antigens produced by cells in the gut.
Yet a norovirus can only grab firmly onto a cell if its proteins fit snugly onto the cell’s blood type antigen. So it’s possible that each strain of norovirus has proteins that are adapted to attach tightly to certain blood type antigens, but not others. That would explain why our blood type can influence which norovirus strains can make us sick.
It may also be a clue as to why a variety of blood types have endured for millions of years. Our primate ancestors were locked in a never-ending cage match with countless pathogens, including viruses, bacteria and other enemies. Some of those pathogens may have adapted to exploit different kinds of blood type antigens. The pathogens that were best suited to the most common blood type would have fared best, because they had the most hosts to infect. But, gradually, they may have destroyed that advantage by killing off their hosts. Meanwhile, primates with rarer blood types would have thrived, thanks to their protection against some of their enemies.

If you don´t know your blood type, contact your physician, donate blood or order a testing kit online.
Sperm donation is also used in cases of rhesus incompatibility. This particularly occurs where a woman has a blood type which is rhesus negative, and where her partner is rhesus positive. The woman’s body may reject a fetus if it has rhesus positive blood. Anti D injections have been developed and may be used to attempt to avoid this, and these are usually automatically given to rhesus negative women immediately after they give birth to their first child. However, in the past this was either not possible or was not always routinely undertaken where a woman gave birth or had an abortion and she may have trouble carrying a child later in life. Furthermore, for some women, the anti D injection does not provide the entire solution, particularly where there is a medical history of complications during pregnancy which risk the woman’s blood and that of the fetus becoming mixed. In such cases, sperm from a rhesus negative donor can provide the solution and a woman may be able to conceive and carry a pregnancy to full term when otherwise this would not be possible. For this reason, sperm from rhesus negative sperm donors is often in great demand, particularly those with the O negative blood group who are universal donors.
It’s been known for about 20 years that the fetus is exposed to maternal antibodies during pregnancy. In fact, maternal antibodies are important to provide newborns an immune boost to fend off pathogens until their own immune systems get up and running. However, a mother’s body can also produce antibodies that negatively affect a child developing within her. Many people are familiar with the risk of Rh-disease that can occur when a fetus has Rh-positive blood but the mother has Rh-negative. Anti-Rh antibodies produced by the mother can cross the placenta and attack the baby’s red blood cells leading to anemia and, if untreated, even kill the child.
The researchers said that the highly specific immunoglobulin-G (IgG) autoantibodies cross the placenta during pregnancy to impact fetal brain development, resulting in a form of autism that the researchers now are calling maternal antibody-related (MAR) autism. The researchers said that MAR autism cases could represent as much as 23 percent of all autism cases.
