Doctors are urging men to turn off their car’s heated seats if they want to stay fertile, for fear that the popular feature could increase the temperature of the testes, adversely impacting sperm production.
Heated seats are becoming increasingly common in vehicles around the world and are particularly popular at this time of year, with temperatures dipping below zero.
But while warming up your frosty private parts on a wintry drive might sound super pleasant, quality sperm production requires the testicles to be several degrees cooler than the rest of the body,
“We’ve known for a while that heating the testicles through the wearing of tight pants or sitting down too long behind the wheel of a vehicle can reduce sperm production,” University of Manchester professor Allan Pacey told the Daily Mail on Friday.
He additionally advises men to stay away from heated blankets this winter season.
“By logical extension, I would imagine that the use of heated car seats or electric blankets during this cold snap might do the same thing,” he stated.
“My advice to any men planning to try for a pregnancy with their partner is to keep their heated car seats and electric blankets turned off,” the doc declared. “It could make all the difference.”
While you may not want to turn on your heated seats for a cross-country road trip, another expert says that occasional, short-term use shouldn’t be an issue.
“Anything that heats up the testes can damage some of the sperm, which makes them less likely to fertilize an egg,” Dr Channa Jayasena, from Imperial College London, told the publication.
“The worst culprits are long cycle rides in lycra or long, hot baths. Occasional use of heated car seats and electric blankets should not be a problem.”
However, it’s not just heat that impacts sperm production, with a Harvard study last year uncovering that occupations can also affect whether a man has a specimen strong enough to reproduce.
Blue-collar workers with physically demanding jobs have almost 50% higher sperm counts than their white-collar office-bound counterparts, the research found.
“We already know that exercise is associated with multiple health benefits in humans … but few studies have looked at how occupational factors can contribute to these benefits,” said reproductive epidemiologist and the study’s first author, Lidia Mínguez-Alarcón, in a news release.
“What these new findings suggest is that physical activity during work may also be associated with significant improvement in men’s reproductive potential,” she added.

醫生警告一種破壞精子數量的常見裝置
醫生敦促男性如果想保持生育能力，就關閉汽車的加熱座椅，因為擔心這項受歡迎的功能可能會提高睪丸的溫度，對精子的產生產生不利影響。
加熱座椅在世界各地的車輛中越來越普遍，並且在每年的這個時候尤其受歡迎，因為氣溫低於零度。
但是，雖然在寒冷的駕駛中加熱你冰冷的私處聽起來可能非常令人愉快，但高品質的精子產生需要睪丸比身體其他部位涼爽幾度，
曼徹斯特大學教授艾倫·佩西周五告訴《每日郵報》：“我們早就知道，通過穿緊身褲或在汽車方向盤後坐得太久來加熱睾丸會減少精子的產生。”
他還建議男士在今年冬季遠離電熱毯。
「透過邏輯延伸，我認為在寒流期間使用加熱汽車座椅或電熱毯可能會起到同樣的作用，」他說。
「我對任何計劃與伴侶一起懷孕的男性的建議是，關閉加熱汽車座椅和電熱毯，」醫生宣稱。 “這可能會改變一切。”
雖然您可能不想在越野公路旅行時打開加熱座椅，但另一位專家表示，偶爾、短期使用應該不成問題。
倫敦帝國學院的查納·賈亞塞納博士告訴該刊物：“任何加熱睾丸的東西都會損害一些精子，從而降低它們使卵子受精的可能性。”
「最糟糕的罪魁禍首是長時間穿著萊卡騎車或長時間洗熱水澡。 偶爾使用加熱汽車座椅和電熱毯應該不成問題。”
然而，影響精子產生的不僅是熱量，哈佛大學去年的一項研究發現，職業也會影響男性是否擁有足夠強大的精子來繁殖。
研究發現，從事體力工作的藍領工人的精子數量比辦公室白領工人高出近 50%。
「我們已經知道，運動與人類的多種健康益處相關……但很少有研究關注職業因素如何促進這些益處，」生殖流行病學家、該研究的第一作者Lidia Mínguez-Alarcón 在新聞稿中說道。
「這些新發現表明，工作期間的體力活動也可能與男性生殖潛力的顯著提高有關，」她補充道。
