Sauna visits may lower men's sperm count

A new study has warned that frequent visits to the sauna may lower men's sperm count, although the effect appears to be temporary. In the study, conducted by researchers at the University of Padova in Italy, healthy Finnish men in their 30s with normal sperm counts spent 15 minutes in a

sauna two times a week for three months, after which they stopped visiting the sauna.

The sauna sessions lowered the men's sperm counts, and they remained below normal for three months after the men stopped visiting the sauna, compared with the levels at the study's start. After six months, however, sperm counts returned to normal.

The findings make sense because higher temperatures are known to affect sperm production, said Dr. Andrew Kramer, a urologist at the University of Maryland Medical Center.

The testicles hang down from the body in men to cool them, Kramer said.

Men with undescended testicles can have impaired sperm product and fertility, according to the researchers.

However, the new study did not assess the men's fertility, so it's impossible to know whether their fertility was lower during the period they took saunas. A man's sperm count does not always correspond to his fertility, Kramer said.

The study also found that sauna exposure affected the way DNA was packed into the sperm cells, and impaired the mitochondria, the cell's powerhouse. This might explain why sperm production is less efficient during sauna exposure, the researchers said.

However, Kramer said the study doesn't provide enough evidence to say that healthy men shouldn't visit the sauna. The study was small, with just 10 people, so more research is needed to confirm the results.

Additional studies are also needed to look at the effects of sauna exposure on men whose fertility is already impaired, or on boys who haven't yet gone through puberty, said study researcher Carlo Foresta, a professor of endocrinology at the University of Padova in Italy.

The study was published online Feb. 14 in the journal Human Reproduction.

常去三溫暖烤箱男人精子數量大減

作者：【記者蘇湘雲／綜合外電報導】 | 台灣新生報 – 2013年3月28日上午12:10

男人如果想「生生不息」，最好少去三溫暖烤箱。義大利研究發現，男性常去三溫暖烤箱，很容易因環境溫度過高導致精子數量大減，但這是暫時性現象，只要不再去三溫暖烤箱，精子數就會逐漸恢復正常。

這項研究已發表於「人類生殖學期刊」。義大利帕多瓦大學研究團隊招募十名健康成年男性參與研究計畫，這些男性年齡大多三十多歲，進行實驗前精子數量都正常，實驗開始後，他們每星期進三溫暖烤箱兩次，每次待十五分鐘，持續三個月，烤箱溫度介於攝氏八十度到九十度之間。

研究人員定期為他們測量精子數量、精子活力、性荷爾蒙濃度等指數。結果發現，男性頻繁進三溫暖烤箱三個月後，精子數量、精子活力大為衰退，就算不再去三溫暖烤箱，三個月後精子數量還是偏低，要等到六個月後精子狀況才會恢復正常。

研究指出，當男性去三溫暖烤箱時，陰囊溫度大約增加攝氏三度左右，這可能影響男性精子製造、生殖能力。美國馬里蘭大學醫學中心泌尿科醫師安德魯‧克拉莫接受外電媒體訪問時表示，溫度過高的確會影響精子生成，會得到這樣的結果並不讓人意外。

研究作者內分泌學教授卡爾羅‧佛雷斯塔提醒，男性若正在努力「做人」，想要和另一半生小孩，或正在接受不孕症治療，最好避免去三溫暖烤箱等高溫場所，以免影響到生殖能力。

老娘覺得這個實驗根本不必做也知道結果，

因為老娘在廚房水煮蛋，蛋白遇熱會變硬啊！

變硬的東西就游不動了，當然就會不孕啊！

但現在講究實證醫學，沒拿出研究報告和數據，人們就不相信。

這些參與實驗的人真是犧牲小我，完成大我。

給他們拍拍手吧！

多力多滋的廣告，在三溫暖拍的，

有點18禁喔!
