有依据吗?

多运动都可以壮阳，和骑车没关系。

多喝补汤。。

多健身肯定比不锻炼有好处，不管什么运动，哪怕是无氧静力运动。而练健美也可以提高性能力。

Does Bicycling Cause Erectile Dysfunction and Impotence in Men?
Updated: March 31, 2008
The answer to this question has received a lot of media attention over the past several years and has also been the topic of heated debate. The answer seems to be that prolonged cycling on a poorly fitting bicycle saddle may be associated with erectile dysfunction (ED), more commonly in older men. But the risk depends upon many factors including the hours of cycling per week, the weight of the cyclist, the skill of the cyclist and the bicycle fit.
What is Impotence and Erectile Dysfunction?
According to the National Kidney and Urologic Diseases, "Erectile dysfunction, sometimes called 'impotence,' is the repeated inability to get or keep an erection firm enough for sexual intercourse. The word 'impotence' may also be used to describe other problems that interfere with sexual intercourse and reproduction, such as lack of sexual desire and problems with ejaculation or orgasm. Using the term erectile dysfunction makes it clear that those other problems are not involved."
What Causes Erectile Dysfunction?
There are many causes of erectile dysfunction and impotence. The physical causes include damage to nerves, arteries, muscles, and tissues responsible for an erection. However, 70% of ED is caused by diseases such as diabetes, kidney disease, chronic alcoholism, atherosclerosis, vascular disease, and neurologic disease.
The most common lifestyle-related causes of erectile dysfunction are:
• Smoking
• Obesity
• Inactivity
Cycling and Erectile Dysfunction
So how can bicycling lead erectile dysfunction? Prolonged pressure on the tissues of the perineum (the area of the groin between the penis and anus) can damage blood vessels and nerves responsible for an erection, and spending excessive amounts of time in the same position on the saddle may cause temporary erectile dysfunction. This damage may become permanent if the tissues are continually damaged and not allowed to recover.
Many factors increase the risk of developing erectile dysfunction in cyclists. Some of these include the weight of the cyclist (heavier riders put more pressure on the perineum), the saddle design (some saddles increase pressure on the perineum), and even the cycling intensity. Studies have found that racing cyclists offset much of the weight on the saddle by keeping so much of their body weight on the pedals. This, in turn, reduces the pressure on the perineum.
Symptoms of Erectile Dysfunction in Cyclists
The good news is that nearly every cyclist who experiences erectile dysfunction or impotence will have symptoms before the problem becomes serious. Reduced blood flow to the perineum causes pain, numbness or tingling in the perineum long before men develop ED. If you don't have problems with pain, numbness or tingling, stop worrying and enjoy your ride. If you do have pain, address the problem before it gets worse.
Preventing Erectile Dysfunction
If you do feel groin discomfort, pain or numbness when you bike take the following actions:
• If you are on a long ride, take a break, stand up on the pedals, stretch and "adjust yourself" until normal sensation returns.
• During rides, change your position frequently by shifting forward and backward and standing.
• Consider adjusting your bike seat to reduce pressure points.
• Use a seat with a cutout to reduce pressure on the perineum.
• Avoid seats with a lot of padding. Although it sounds comfortable, you'll actually sink deeper into the saddle and feel more pressure and numbness.
• Keep the seat level or angled slightly downward; never tilt the saddle upward.
• Raise your handlebars slightly so you are a bit more upright.
• Change positions often during your rides.
• Wear good cycling shorts with a comfortable pad.
• Adjust your saddle height so that your knee is just slightly bent at the bottom of the pedal cycle.
• See: Proper Bike Fit Can Prevent Pain and Injury
Bicycle Saddle Choice
Bicycle saddle design has changed dramatically over the years and there are many options. Saddles now offer a cutout down the middle to relieve pressure on the perineum and reduce pressure on the soft tissues. Some research supports this theory and many cyclists find that the cutouts are more comfortable than traditional saddles. Newer saddles, such as the Selle SMP, offer a large cutout and downward facing nose. One study found this design superior in allowing penile blood flow compared with standard saddle shapes.
Another study on saddle shape and penile blood flow found that narrow saddles result in less blood flow than a wider saddle. Computer analysis of pressures showed that a wide saddle allowed more weight to be distributed to the sit bones (ischial tuberosity) and put less pressure less on the perineum than narrow saddles.
So if you don't have symptoms, don't worry about impotence and enjoy cycling!

懂了

看来向下凹陷的设计很有用
我觉得关键是坐骨的支撑宽度如果和车座比较合适的话，调整一下坐姿就好了---可惜我骑着骑着坐姿就变了

我只听过骑车会影响生育能力

坐姿变是因为车架尺串不对吗?

长期骑自行车容易患前列腺炎,到老容易增生

骑车要注意哦！

无意间逛逛医学版，居然发现这个隐患，怕怕啊

不是吧，前列腺......

不敢想下去了

。。。。。。这个。。。。

男人到老80％都会有前列腺炎和增生，如果长期骑自行车更会加重，这个是没办法的，在座垫上下点功夫还是有点效果，任何运动过量都会对人体有损伤，只能量力而行了！！！！！！！

俺认为适当的坐垫和适合的骑姿不仅不会影响性功能，反而更有益于健康。

而一些出了问题的车手往往是在坐垫上和骑行上姿态不对或者不合适导致下体出毛病

作者: 幽灵 时间: 2009-6-16 12:33
这里面还有强调一点就是车友本来就要健康的，如果本来有点问题，那么骑行或许不一定合适

作者: 每文华 时间: 2009-6-17 00:06
骑车练得的就是下半身，男人就是为了下半身而活的，所以男人要骑车。。。哈哈开个玩笑

我倒是听说骑车会有什么睾丸癌，影响泌尿系统之类的，不过我同意幽灵说的，和座垫、姿势有关，合适的座垫+正确的姿势，应该是不会有上述问题的；另一方面，我比较喜欢骑车的时候经常性的站骑，有助于全身的锻炼，包括腰部、手臂，个人意见，仅供参考

我一个球友，他说他的一个亲戚，结婚7年了，没有小孩，后来去检查最后诊断跟长期骑自行车有关系

25楼的建议比较好，长时间骑行可以充分考虑站资骑车一小会，使血液通畅全身，免得局部过多小循环
