  According to the Daily Telegraph of October 28, a diet rich insaturated fats, such like fried bacon, sausages, butter and cream -could cut the sperm count by almost half, found researchers at HarvardMedical School in the US。

  Their study discovered that it did not matter if the man was fat orthin - such a diet had the same negative effect on sperm concentration。

  Dr Jill Attaman and colleagues looked at 91 men seeking fertilitytreatment and asked them how often they ate certain foods, what types ofoil they used in cooking and baking and the types of margarine theyconsumed。

  Overall, men with the highest saturated fat intake consumed 13percent of their daily calories as saturated fat, while those in thelowest took in eight percent。

  The study concluded: "Men in the highest third saturated fat intakehad 41 percent fewer sperm than those in the lowest third."

  Dr Jill Attaman said diet could have a greater impact on ability tofather a child among men with a lower base level of spermconcentration。

  While the exact reasons for the apparent link between diet andsperm quality remain unclear, she said that "dietary modifications couldbe beneficial for global health as well as reproductive health"。

  据英国每日电讯报10月28日报道,美国哈佛医学院的研究人员发现,常吃富含饱和脂肪的食物,例如炒腊肉、香肠、黄油和奶油,可能会将男性体内精子数量减少一半。

  他们的研究发现,男性不管是胖还是瘦,这种富含饱和脂肪的食物都会大大降低精子浓度。

  吉尔?阿塔曼博士和她的同事们对91名寻求不孕治疗的男性进行调查,询问他们多久食用一些特定食物、平时食用何种油进行烹饪以及食用何种人造黄油。

  整体而言,饱和脂肪摄入量高的男性每日食用食物13%都是富含饱和脂肪,而摄入量低的男性每日食用食物只有8%的是富含饱和脂肪的。

  研究得出,饱和脂肪摄入量高的男性体内精子数量要比饱和脂肪摄入量低的男性少41%。

  吉尔?阿塔曼博士说,对于体内精液浓度不高但是还想生育小孩的男性来说,饮食有着非常重要的影响。

  尽管目前饮食和精子数量之间为何有密切联系的确切原因尚不清楚,但是阿塔曼博士说:“改变饮食习惯不仅有益全球健康,也有益于人们的生殖健康。”
