Eating whole-milk products instead of skim or low-fat ones may decrease the risk for a certain type of infertility, new research has found.
Scientists found that women who consumed one or more servings of whole-milk products a day were 27 percent less likely to experience infertility caused by a failure to ovulate than those who ate less than one serving a week. At the same time, women who ate two or more servings a day of low-fat dairy food were almost twice as likely to fail to ovulate as women who ate less than one serving a week.
Scientists followed more than 18,000 premenopausal women without a history of infertility over an eight-year period. In that time, there were 438 diagnosed cases of infertility because of failure to ovulate. The study appeared Feb. 28 online in Human Reproduction.
The study found that an extra eight-ounce serving of whole milk daily had the greatest effect, cutting the risk of failure to ovulate by more than 50 percent. The effect of eating an extra half-cup of ice cream a day, however, was not statistically significant.
Dr. Jorge E. Chavarro, the lead author and a research fellow at the Harvard School of Public Health, said that at least one previous study contradicted his results. 揟here is as yet no clear picture of the role of dairy food in fertility,?Dr. Chavarro said, and he was not prepared to recommend whole-milk foods to women trying to become pregnant.
The authors acknowledge that some subjects may have already received diagnoses of ovulation problems and were therefore avoiding high-fat dairy products, and that this could have affected the results.

适度饮用全脂牛奶有助于怀孕
Eating whole-milk products instead of skim or low-fat ones may decrease the risk for a certain type of infertility, new research has found.
一项新研究发现，饮用全脂牛奶而不是脱脂或低脂牛奶可能降低某种不育症的发病。
Scientists found that women who consumed one or more servings of whole-milk products a day were 27 percent less likely to experience infertility caused by a failure to ovulate than those who ate less than one serving a week. At the same time, women who ate two or more servings a day of low-fat dairy food were almost twice as likely to fail to ovulate as women who ate less than one serving a week.
科学家发现那些每天饮用一次或更多全脂牛奶的妇女比那些一个星期饮用少于1次的妇女发生由于排卵障碍引起的不育几率低27%。同样，在排卵障碍的妇女中，每天有两次或以上低脂饮食的妇女是一周少于1次低脂饮食妇女的2倍。

科学家跟踪调查了18000名无不育史的绝经前妇女，这项研究持续8年，这段时间内，有438例确诊为不育症是由排卵障碍引起的。2月28日这项研究在线发表于人类生殖。
The study found that an extra eight-ounce serving of whole milk daily had the greatest effect, cutting the risk of failure to ovulate by more than 50 percent. The effect of eating an extra half-cup of ice cream a day, however, was not statistically significant.
研究发现每日多喝8盎司的全脂牛奶效果最好，可降低排卵障碍发生率50%以上。然而每天多吃半杯冰激凌的效果并没有统计学差异。

研究主要作者，哈佛大学公共卫生学院研究员Jorge E. Chavarro博士说至少有一项先前的研究与他的结果相矛盾。乳制品在生育中的作用还不完全清楚。他并不准备向那些想怀孕的妇女推荐全脂饮食。
