Blood Type O Linked to Fertility Problems

Researchers say having type O blood can affect a woman’s chances of getting pregnant.  Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood type A seem to be more fertile. Scientists from Yale University and the Albert Einstein College of Medicine have produced a study that finds patients with type O blood were at double the risk of diminished ovarian (egg) reserve than women of other blood types.

The researchers measured women under age 45 for levels of the reproductive hormone FSH.  Women with an FSH of greater than 10 are considered to have diminished ovarian reserves (egg quality and number of eggs left).  FSH levels greater than 10 suggest a woman will have more difficulty conceiving than those whose levels are under 10.

They then made adjustments for other fertility factors including age and BMI, then compared women’s blood types and FSH levels. Women with blood type A or AB were significantly less likely to have an FSH level greater than 10 than were women with types O or B blood.

In the U.S., 45% of the population is type O, 40% type A, 11% type B and 4% type AB.

FSH levels are just one marker of fertility and more studies are needed. Dr. Edward Nejat said, "A woman's age remains the most important factor in determining her success of conceiving.”

Higher FSH is simply the result of the pituitary gland trying to improve the ovaries' response. If you nourish and support your ovaries, they become more responsive to the pituitary gland's hormonal messages, it senses that less FSH is needed, and your levels will drop.

At ilumina we can help by increasing blood flow using acupuncture to improve blood flow to the ovaries; better circulation will improve the function of the ovaries, the follicles, and the eggs.  Chinese herbs can balance the hormones, which addresses underlying patterns of imbalance that can restore natural, balanced hormonal function.  By stimulating the body's own reproductive tissues at different parts of the reproductive cycle, herbal medicine offers a gentler, healthier, more organic response to fertility problems. When hormone levels are balanced, and when adequate blood flow, oxygenation and nourishment are provided during the follicular growth phase, women are more likely to become pregnant naturally with their own healthy eggs.
