熱水澡對男性生育能力有不良影響

Really?
The Claim: Regular Use of Hot Tubs Can Hurt Fertility in Men(原文連結)

這個傳說無論中外都很有名,不可否認所有男生都在意這件事,到底經常泡熱水澡是否對男性雄風有影響呢?除了泡太多熱水不好外,也有泡冷水對那方面有益的說法,另外傳說中冷熱水交替的所謂金冷法(到底是哪國人發明的?),不過我並不想讓我的網頁走情色路線,所以還是看正題吧.

For years, doctors have warned men having trouble conceiving to stay away from hot baths and whirlpool tubs, saying there was reason to suspect that long exposure to hot water could worsen their problems.
多年來醫生警告有生育問題的男人要遠離泡熱水澡按摩浴缸,合理的懷疑長時間泡熱水會讓他們的問題惡化.首先男性雄風不等於生育能力,在這裡其實討論的是生育能力,想知道強壯秘方的同儕們,相信我和你同樣失望(被插圖欺騙).

連續看數篇相關題材的文章有個好處,就是強化對那些字重複的印象,conceive在這裡當使受孕,當然fertility又再次出現.

Much of that was based on speculation. But earlier this year, a team of urologists at the University of California, San Francisco, conducted a study to measure and document the extent, if any, of this effect. The researchers did confirm the link, and then they discovered something surprising.
這些大多是根據推測而來,但是今年(2007)稍早加州大學的一組泌尿科專家團隊,導入一套研究來測量記載這個說法的真實性,如果為真,影響有多大.這些研究者確認了這之間的關聯,並發現了一些驚人的事實.

The study looked at a group of men who were regularly exposed to high water temperatures, meaning for about 30 minutes a week, through hot tubs or hot baths.
這個研究觀察一組人經常暴露在高水溫下,每週最少30分鐘,泡熱水澡或是以高水溫淋浴.

All the men showed signs of infertility, with impaired sperm production and motility.
所有男人都有不孕的跡象,伴隨著精子的量與活力的降低.
impair:If something impairs something such as an ability or the way something works, it damages it or makes it worse. (FORMAL)
        e.g. Consumption of alcohol impairs your ability to drive a car or operate machinery...

What was unexpected was how quickly this infertility could be reversed. The researchers found that after the men stopped their exposure to wet heat, half had “a mean increase in total motile sperm counts of 491 percent after three to six months.”
令人意外的是這種不孕跡象回復的速度,研究員發現當這些男人停止洗熱水,他們之中的一半在三到六個月後有活力精子的總數平均增加到491%.

Among the men who did not see such a reversal, the researchers speculated that tobacco use, a known “gonadotoxic” habit, was to blame. Most of those men were chronic smokers.
另外一半沒有觀察到這種轉換的男人,研究員懷疑是抽菸,一個已知的"損害產生精子能力"壞習慣,的影響.這些人大多都是吸菸者.

THE BOTTOM LINE
Regular exposure to hot tubs can hurt male fertility, though the effects can be reversed.
結論
經常性的熱水澡會影響男性生殖能力,雖然這個情形是可以恢復的.

呃,用洗熱水澡來替代家庭計畫嗎?我想這不是個好主意.畢竟世界上總是意外的事比較多.
古時候人連踩到巨大腳印都可以懷孕也(后稷的母親踩了天帝的巨大腳印,便神奇地懷孕了,後來生下了一個嬰兒-后稷,我想他的青春期不會太愉快.還有他父親應該也不太愉快)

古人顯然沒有.infertility 的困擾,生活困苦沒熱水洗吧.
