肥孕婦會影響兒子生育能力

 女人真的該減肥了,不然可能「禍延子孫」喔!因為最新研究顯示,胖孕婦會影響兒子的生育能力喔!!

丹麥最新研究指出,肥胖孕婦生下的男嬰會出現生育力下降的問題,他們精子的活躍度會較低。這是是全球首個揭露肥胖與下一代生殖力有關連的研究。

英國《每日郵報》報導,丹麥阿爾胡斯大學的研究員對300名婦女及其兒子的健康進行研究,當中25名婦女的身高體重指數(BMI)超標,即屬於過肥或癡肥等級,而她們兒子的精子活躍度都表現較差。負責的學者表示,雖然結果顯示兩者差距不大,但警告體重超標的女性應留意,並認為過重的女性體內含有較高濃度的雌激素,而雌激素會影響男性胎兒生殖器官發展。

Sons of fat mothers 'could be less fertile'

肥媽的兒子「生育力可能較差」
 

A recent study has revealed that sons born to fatty women can be less productive and may have poorer quality sperm cells.

最近一項研究揭露,肥胖婦女所生的兒子,生育力有可能較低,精子品質也可能較差。 

Obesity is believed to have an effect on a woman’s possibilities of pregnancy, and the latest study is the initial to discover a relation between overweight and the fertility of the next generation.

肥胖據信會影響婦女受孕機率,這項最新研究則首度發現,體重過重與下一代的生育能力也有關聯。

   The researchers tracked the health of more than 300 women and their sons. although the majority of the women were of normal weight when they became pregnant, 25 had body mass indexes classed as overweight or obese.

研究人員追蹤逾300名婦女及其兒子的健康狀況,雖然多數婦女懷孕時體重都正常,其中25名婦女的「身體質量指數」(BMI)仍被歸類為過重或肥胖等級。

  Tests showed their sons tended to have slightly lower concentrations of sperm, as well as fewer mobile sperm.

 檢驗結果顯示,她們兒子的精子密度傾向於稍低,精子也較不活躍。

However, the differences were so small that the researchers could not be sure they were not due to chance.

The team, from Aarhus University in Denmark, said further studies should be carried out.

然而,這些差距都很小,研究人員無法確定它們不是碰巧發生。 丹麥阿爾胡斯大學的研究小組認為,應該作進一步研究。

They added that it was possible that higher levels of the hormone oestrogen, associated with being overweight, might harm the development of male foetus reproductive organs.

他們補充說,這可能是因為(這些母親體內)雌激素濃度較高,而這種與體重過重有關的激素,也許會影響男性胚胎生殖器官的發展。 

新聞辭典

obesity:名詞,(過度)肥胖。形容詞為obese。obese和fat的主要分別是,前者是較科學和嚴謹的說法,而且包含「不健康」的意思。例如BMI超出標準,稱為肥胖,這種肥胖就叫obesity;而fat則是一般描述,很多時只是主觀感覺,不一定不健康,所以兩個字在大多數情況下不能互換。
