A study jointly conducted by American scientists found that women with type O blood are less likely to become pregnant than women with other blood types. Experts suggest that women with type O blood who want to have children should consider it early.
A research team led by Edward Nezart, a scholar at the Albert Einstein College of Medicine in New York, USA, conducted this study while participating in the in vitro fertilization project at Yale University in the USA. The results found that among 560 women with an average age of under 35, women with type O blood were less likely to conceive than women with other blood types.
Group with the highest chance of pregnancy She is a woman with type A blood.
Experts explain that women with type O blood may secrete more \”follicle-stimulating hormone\”, and this hormone will inhibit ovarian ovulation. Studies have found that women with type O blood secrete more than twice as much follicle-stimulating hormone as women with type A blood.
The British \”Sunday Telegraph\” reported on the 24th, citing the results of this study, that when women reach the age of 30 to 40, their ovarian ovulation will decrease. At this time, the more \”follicle-stimulating hormone\” is secreted, the less likely the ovary is to ovulate.
The difference in the amount of \”follicle-stimulating hormone\” secreted by women with different blood types may be genetically determined.
The vast majority of British people have type O and type A blood, with 42% of type A blood and 44% of type O blood.
Tony Rutherford, president of the British Society for Reproductive Medicine, said: \”This is an interesting study, but its results need to be confirmed.\” He believes that the study should be conducted on a society-wide scale, rather than Conclusions were drawn only among women who applied for in vitro fertilization.
