偶而騎是可以
 

偶而騎是可以的 但 長時間騎腳踏車時 坐在腳踏車座位的壓力會擠壓對小弟弟供血的動脈和下陰的神經而引響產生快感及供血的能力 使得對小弟弟勃起的功能產生不好的影響 長久下來會導致陽痿 .... 要長時的當成運動的話 小弟認為應該還有別的運動可以代替吧..個人意見吧 除非現在的腳踏車座位有更好的設計

The area in question is the perineum, between the external genitals and the anus. "When you sit on a chair you never put weight on the perineum," Dr. Schrader said. "But when you sit on a bike, you increase pressure on the perineum" sevenfold.

In men, a sheath in the perineum, called Alcock's canal, contains an artery and a nerve that supply the penis with blood and sensation. The canal runs along the side of a bone, Dr. Goldstein said, and when a cyclist sits hard on a narrow saddle, the artery and the nerve are compressed. Over time, a reduction of blood flow can mean that there is not enough pressure to achieve full erection.

以前國中騎了三年,現在還是雄糾糾,氣昂昂的啊 :confused:

辛辛苦苦騎腳踏車健身，卻得不到小弟弟健康的消息











悶悶悶 :nonono: :nonono: :nonono:

裡面有說 Just as many smokers do not get lung cancer, many cyclists will never develop impotence from bicycle seats, the scientists said. What makes one person more vulnerable than another is not known. Body weight seems to matter: heavier riders exert more pressure on saddles. Variations in anatomy may also make a difference.

依文章說也是要看身體的重量和騎的時間吧 假如身體的重量很重又長時間騎的話 座位對下陰的壓力也會更重 也更容易導致陽痿 身體輕的較不容易 像文章所說的 並不是 所有抽菸的人都會得肺癌 也是有不同的因素 . :ase

如果真的要騎的話
可以換中間有空洞的坐墊
那就是給你放小弟弟的 :D

拿掉旦旦..摩差力比較小..

想起以前辛辛苦苦的騎單車上國中
卻得不到應有的尊重
還要跟汽車搶路
最重要的是我弟弟卻麻.................. :ase :ase :ase :ase :ase
