小李是個自行車愛好者,每天都要騎車兩個多小時。有時,會陰部有麻木、脹感,休息一會兒,症狀大多會消失。最近,他發現勃起差了,性交時間也縮短了。小李懷疑這可能是騎自行車惹的麻煩。
像小李這種情況在臨床上很常見。近10年,國外開始關注騎車與男性勃起功能障礙的關係。挪威對160
名參加自行車越野賽的選手進行調查,發現33人報告陰莖麻木、感覺遲鈍或敏感性喪失,21人確診ED。德國對1100多名自行車愛好者調查後也發現,58%—70%的人都出現了生殖器麻木。這一研究報告還說明,陰莖麻木程度和騎行距離、時間成正比。
我們知道,當人們坐在狹小的自行車座上時,每單位麵積承受的體重是坐在椅子上的七倍多。此外,車座對會陰的過度壓迫,使之承受的壓力會超過動脈收縮期的血壓。這時陰莖血液供應會出現暫時阻斷,動脈血管內皮會出現不同程度損傷,進而導致血管性ED。
在歐美國家,很多人開始用一些新型、彈性較好、能減少對會陰部壓力的自行車坐墊。我國作為一個自行車大國,對於騎車與男性勃起功能障礙的關係還沒有足夠重視,這是目前急需強調的問題。(浙江中醫藥大學附屬第二醫院副院長
