three-pregnant-womenA study out of Yale University and the Albert Einstein College of Medicine has found that women with blood type O are at double the risk of diminished ovarian reserve than women of other blood types. However, one expert on fertility says more research needs to be done after these “surprising and stark” findings.

Women under the age of 45 were measured for levels of the reproductive hormone FSH. An FSH level greater than 10 indicated diminished ovarian reserve. Other fertility factors including age and body mass index (BMI) were considered before comparing the blood types and FSH levels of patients.Researchers discovered that women with types A or AB blood were significantly less likely to have an FSH greater than 10 than were women with types O or B blood.“This is a novel look at a poorly understood part of reproductive aging. Through studies like these we will be better able to understand the complexities of the human reproductive system,” says William Gibbons, MD, president of the ASRM. In Australia, 49% of Australians have type O, 38% type A, 10% type B and 3% type AB.More research is needed, however. The FSH method isn’t the most accurate for measuring fertility but can assess approximates of egg reserve. A more precise marker of ovarian reserve is to measure a woman’s anti-mullerian hormones (AMH).

Richard Fleming, PhD, and scientific director of the Glasgow Centre for Reproductive Medicine comments on type O women wanting to have a baby, saying “It is an interesting, and to me, quite surprising finding that needs to be substantiated. Therefore, the implication for someone with type O is number one, don’t worry.”“Number two, if women have fertility concerns,” Fleming says, “get their AMH measured, not their FSH.

Naturopathic Medicine focuses on increasing the quality of eggs as well as the DNA integrity through the use of specific herbs and nutrients. Research has validated the use of antioxidant therapy for preserving both egg and sperm quality. A thorough and careful preconception plan will help to ensure that you reduce the risk of conception difficulties.
