Study scientists have discovered for the first time that a woman’s blood group could influence her chances of getting pregnant.
Researchers found that those with blood group O are at much higher risk of running out of healthy eggs, so could have problems conceiving as they get older.
Researchers who tested a group of women seeking fertility treatment found those with the blood type O appeared to have a lower egg count and poorer egg quality than others. By contrast those with blood type A seemed to have more and better quality eggs.
American researchers found that those with blood type O were twice as likely to have low ‘ovarian reserve’, the number of healthy eggs left than those with other types.
The size of a woman’s ovarian reserve gradually falls throughout her life. A newborn girl has up to two million eggs, but by the time she reaches puberty this has fallen to 400,000 and once she is over 40 she will have just a few hundred left.
Researchers from Yale University and the Albert Einstein College of Medicine, New York, looked at the blood type of 563 women under 45 who were undergoing fertility treatment.
They compared their levels of Follicle Stimulating Hormone (FSH) a chemical in the blood which, if high indicates a woman has a poor ovarian reserve. FSH levels greater than ten suggest a woman will have more difficulty conceiving, women with FSH levels higher than 20 are deemed infertile.
The breakthrough could lead to women basing their decision on whether to pursue a career or start a family on their blood type. The researchers said that in future women could make decisions on when to start a family based on their blood type.
But they acknowledged that many ‘type O’ women have successfully had children and that there are dozens of other factors affecting fertility such as age, body weight and alcohol consumption.
