Infertility and Your Blood Type
It is now known that a woman's chances of becoming pregnant can be influenced by her blood group.
More than 560 women with an average age of 35 undergoing fertility treatments took part in the latest research, led by experts from Albert Einstein College of Medicine in New York and Yale University.

Those with blood type O may struggle to conceive.
The study found that those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality. Women with blood group A, however, seem to be better protected against falling egg counts. Read the Evidence... 
Study conducted at the Albert Einstein College of Medicine in New York and Yale University. Blood samples were taken to measure levels of follicle stimulating hormone (FSH), a well-known marker of fertility. FSH levels greater than 10 suggest a woman will have more difficulty conceiving than those whose levels are under 10.
A high FSH level indicates a diminished ovarian reserve, which refers to both egg quality and the number of eggs left available for fertilisation. Ovarian reserve tends to decline significantly as a woman reaches her middle and late 30s and faster in the early 40s.
The study found that women who were blood type O were twice as likely to have an FSH level greater than 10 as those in any other blood group. [ x ] |

Our Opinion
Whilst your blood group may play a role in a woman's fertility, it is important to remember that many ‘type O’ women have successfully had children and that there are dozens of other more important factors affecting fertility such as age, body weight and alcohol consumption.
