Most of the 30 years old women’s began to use medical help to increase fertility. This is not just due to aging alone but blood group apparently had an influence on fertility. Women with blood type O tend to decrease the amount of the egg reserves than other blood types. Women with blood type O are two times more likely to experience a decrease in fertility compared to women with blood group A and AB. Doctors stated that egg reserves will be reduced in women aged 30-40 years, but can also occur at an early age. This research has been published online in the journal Human Reproduction issue of June 26, 2011.
“There is a subgroup of women who are young but her acting as if the older and the number of eggs in her ovaries a little more,” said Lubna Pal, a reproductive endocrinology researcher at Yale University School of Medicine as reported from MSNHealth, Wednesday (21/3 / 2012).
The researchers measured the levels of follicle stimulating hormone (FSH) to determine whether the egg reserve may be reduced. Approximately 544 women in Connecticut and New York who use fertility assistance a median age of 35 years. After giving effect of age the researchers found that, women with blood type O have a high FSH level indicating decreased egg reserve. Women with blood type O are two times more likely to experience a decrease in fertility compared to women with blood group A and AB.
“Red blood cells have a molecule that attaches to the cell surface such as a flag pole. People with blood type A, AB, and B have enzymes that can modify the molecule as the process of raising the flag on a pole. In blood group O, the flag does not seem to be raised. There the possibility that the blood type O do some unknown function in ovarian cells, “said Pal.
“The process works in the blood may also work in the ovary, but needed a more robust evidence,” said Pamela Stanley, a professor of Biology at the Albert Einstein College of Medicine.
“Still need to do more research on the relationship between blood type O and decreased egg reserve,” said Pal.
A woman’s blood type and the ability to conceive may be related, but lifestyle can also affect fertility.
