　　Blood Type O May Be Barrier to Having A Baby

　　研究发现："O型血"女性更不容易受孕

　　A study suggests that a woman’s blood group could influence her chances of getting pregnant.

　　一项研究显示，女性的血型可能会影响她受孕的机会。

　　Researchers who tested a group of women seeking fertility treatment found those with the blood type O appeared to have a lower egg count and poorer egg quality than others. By contrast those with blood type A seemed to have more and better quality eggs.

　　研究人员对正在寻求生育治疗的一组妇女进行研究，发现"O型血"妇女的卵子数量要比其他血型的妇女要少，而且质量也不如其他血型妇女。相反，"A型血"妇女似乎有更多、质量更好的卵子。

　　The findings could lead to women with type O blood being advised to try for a baby earlier, but experts said more research was needed before such a step was taken.

　　这一发现可能会帮助"O型血"妇女接受建议，尝试更多办法，更早的怀上小孩。但是专家说在采取这样的方式之前，还需进行更多的研究。

　　The lead author, Dr Edward Nejat, of the department of obstetrics and gynaecology at the Albert Einstein College of Medicine in New York, said his findings were based on women having fertility treatment at the Yale University and the Montefiore Institute in New York.

　　研究领导者、纽约阿尔波特?爱因斯坦医学院妇产科系爱德华?奈加特教授说，他的调查是对正在耶鲁大学和纽约蒙特菲奥里研究所接受生育治疗的妇女进行研究而来的。

　　The study of 560 women, whose average age was just under 35, found that those with blood type O were more likely to have higher levels of “follicle stimulating hormone” (FSH) than those with type A.

　　接受调查研究的560位女性平均年龄在35岁以下，研究发现"O型血"妇女的卵泡刺激素(FSH)的数值比"A型血"妇女要高。

　　Fertility experts regard a high FSH level as a key indicator of having a low egg count. FSH is produced by the body to stimulate the follicles in the ovaries that produce eggs.

　　生育专家将卵泡刺激素的数值作为重要指标来衡量女性体内卵子数量，数值高则卵子数量少。卵泡刺激素由体内产生，以刺激卵巢中的卵泡产生卵子。

　　As a woman’s ovaries run out of eggs in her 30s and 40s, production therefore has to be stepped up to encourage more eggs. The presence of high levels of FSH indicates lower numbers of eggs.

　　处于30岁到40岁之间的女性，她们的卵巢可能就不再产生卵子，所以需要通过(其他方法刺激)让其产生更多卵子。高数值卵泡刺激素则意味着更少的卵子。

　　The study found that women with blood type O were twice as likely to have an FSH level above 10 as those in any other blood group.

　　研究发现，"O型血"妇女体内的卵泡刺激素数值很可能是其他血型妇女的两倍，数值在10以上。

　　People with blood group A carry the A antigen, a protein on the cell surface, that is absent in people with O type.

　　"A型血"人群体内携带A血型抗原、一种细胞表面的蛋白质，这种蛋白质在"O型血"人群中是没有的。
