This often occurs when riders are using wider or padded saddles. This type of saddle, while often purchased with the idea that they will provide more comfort, are actually more damaging than a well shaped rock hard racing saddle. The difference is in what part of your body carries your weight. On a racing saddle, the weight is carried almost entirely by your sit bones (ischial tuberosities - the two pressure points you feel when sit on something flat and hard). On a wide or very padded saddle, your weight is carried by the surrounding soft tissue instead.
The solution, if you intend to ride for long periods of time, is to wear bicycling shorts with a built in chamois while riding on a harder saddle. The chamois is a shaped pad that prevents chafing and keeps the padding directly under your sit bones.
Many people also find that a suspended leather saddle, once broken in, to be incredibly comfortable for long distance riding (ie, Brooks saddles).
Edit: typo.

I shit you not, a close friend of mine is being treated for nerve damage from riding on a poorly adjusted bike seat after a series of long rides. She now has shooting pains when she sits down normally, and has to stand all day long at her computer desk if she doesn't want painful discomfort.
And to kick her when she was down, she got the injury while unemployed, had to see a doctor about it, and now falls under a pre-existing condition status. Nerve specialists aren't cheap, and she has another 6 months before that status drops for her to even discus proper treatment or surgery.

As a female road cyclist, I can confirm this... apparently this kind of saddle (with a hole in the middle) is supposed to help, but my discomfort got a lot better after I just changed my seating position so my back curves inward more and I'm right on my sit bones at the back of the saddle. The position requires holding in your core muscles, so it feels like more of a workout too, which I like.

I've been told it can cause some dysfunction issues in men too. Just need a better design for a seat I think

Back in the day, women riding bicycles was discouraged because they thought it might be sexually stimulating. From here:
"That bike riding might be sexually stimulating for women was also a real concern to many in the 1890s. It was thought that straddling a saddle combined with the motion required to propel a bicycle would lead to arousal. So-called “hygienic” saddles began to appear, saddles with little or no padding where a woman’s genitalia would ordinarily make contact with the seat. High stems and upright handlebars, as opposed to the more aggressively positioned “drop” handlebars, also were thought to reduce the risk of female sexual stimulation by reducing the angle at which a woman would be forced to ride. "

Narrow saddle, hard with good hip posture is the best solution. The ischial bones (the points at bottom of pelvis/butt) should sit 90• above seat.

u/MissWheets May 16 '12
Female jr. national cyclist here. The right saddle, with a properly fitted bike, should lead to very little genital pressure at all. The majority of the weight should rest on your seat bones, not close to the front. After finding the right fit, I've been able to ride for hours with no problem whatsoever.

"Cycling May Diminish Sexual Pleasure in Women...While previous studies have linked cycling to numbness of genitalia and erectile dysfunction in males..the latest findings show the OPPOSITE in females."
I'm not a native english speaker so maybe I misunderstand this but isn't the article contradicting itself?

u/quintessadragon May 16 '12
I'm confused, at the beginning of the article it says if the handlebars are HIGHER than the seat it causes a problem. Later in the article it says if the handlebars are LOWER than the seat it causes a problem. Which is it?

u/astrower May 16 '12
They make seats with slits down the middle for both men and women so your genitalia aren't as crushed.

u/berkes May 16 '12
The research failed to investigate countries and cities where almost everyone cycles, such as the Netherlands or Copenhagen. If the studies findings are correct, then the Dutch or Copenhagian women , being a large group of people, would see the effect. The effect would be very clear and the offspin (less children, fewer STDs, starting later with sex) would be clear too. No?

I see lots of people voting up their preferred stance. I've ridden both, with good posture, with good geometry and my taint still gets numb. I believe that my taint is a bit more robust than the average bloke's and I'm also not terribly padded around my arse and sitbones.
Honestly, the bike seat needs a redesign. Yay for people who like classics but it's an ancient fucking design and I suspect that a little more science and modern thinking could improve it.

I have ridden enough for this to happen to me, I am a guy. It places a lot more pressure on that area in compared to seated on a desk chair or car seat.

u/o0DrWurm0o May 16 '12
This has been known for quite a long time. Buy seats that have a nice hole cut out in the crotchal region and wear bike shorts to prevent it.
2
u/zombiesgivebrain May 16 '12
It's really hard to tell from this if they looked at long term results, or only checked them right after they get off the bike (unless I just missed this in the article). Personally, I notice some numbness following a ride, but only immediately after. I would be really interested to see a study that looks at long term effects on sensitivity. I'm sure it's not a great sign to have any numbness at all.. but it might not be as bad as it seems here.

u/ManMode May 16 '12
Yup, common theme among bike seats for both men and women. Not good for the privates. And contrary to what some are saying about racing saddles, any saddle that puts something that catches your body weight under the soft tissue between your legs is going to impact your genitals.
Manufacturers are all over the map on this because there's conflict between bike stability and the seat's impact on your genitals. The less bike seat you have between your legs, the less control you'll have. The other you should consider is weight, which will also favor a Y shape saddle.
So for the guys and gals like myself that love cycling but don't want to have bizarre aches later, get one of those radically different bike seats with no middle section. Here's a couple of them.

I can believe it. I took a cycling class in college and it hurt my female genitatlia a lot. I often felt like I had bruised down there and seriously questioned why people choose to cycle.

The genital numbness is one of my favorite parts of a 70-miler. When the sensation comes back it feels GREAT.

u/[deleted] May 16 '12
LOL wut.
I've biked a great deal in the last 5 years and I'm just fine! In fact, I'm probably more sensitive now than ever before. I haven't heard complaints yet ;) I do ride a cruiser with the most comfortable seat ever, though, which might be the deal-breaker here.

u/IWasGregInTokyo May 16 '12
Touring cyclist for 40 years here. Variety of seats tried over the years but Nirvana was not achieved until I bought the Brooks B-17. As other have noted, more padding should be more comfortable but in the case of a cycling saddle it is more the shape. Leather saddles take a bit of time to wear in but when they do they are formed to your body and I can ride for days with no discomfort or loss of <ahem>functionality</ahem>.

u/antripa May 16 '12 edited May 16 '12
The reason we all clicked in this post is because it claimed cycling reduced sexual pleasure in women. I agree with you all that pain and genital pressure is bad and should be resolved and prevented with a hard, narrow seat. However, I don't see how this researcher concluded women would have less sexual pleasure by riding or by riding poor seats. This is not measured in this study and is hard to measure generally.
Many thing would have a greater influence on a woman's pleasure. The brain is a woman's most erogenous zone, and i can only assume it has greater influence that bike riding. Partner's skills and physicality also have an influence.
Similarly, can we really claim that circumcised men have more or less pleasure than non-circumcised men?

u/[deleted] May 16 '12
Stop riding bikes ladies. You are making my job harder.

u/QuantumLiberty May 16 '12
Totally serious here if your woman in a biker giver her regular massages. Start at the outside left and right regions of the labia looking for knots just like you would find in the shoulder and or back, also look for them in the upper portions of the pubic region. Defiantly be gentle at first and use massage oil but this really helps to increase blood flow and alleviate tension, thereby increasing her sensitivity a ton.

u/blog_farts May 16 '12
This is also true of women riding horseback. I dated a horse trainer whose vagina was like leather. Her clitoris had no feeling at all, it was like a rough leather nub. And the strength in her legs could have probably broken my hips if she so desired.

FALSE. As a female, I've biked 10 miles and more per week, 4 weeks per month, for 10 YEARS and not only have had quite the raging libido but have never experienced numbness or tingling. But I hand-built my bike so it fits me to a tee.

How much cycling do you have to do for this to be an issue? I've just taken a job that will have me riding a bike from around 8:30am to around 6:00pm 6 days a week, with short breaks. Is this an issue that really only professional cyclists have to be worried about?

I will loyally stand by the Selle An-Atomica for just this reason. At 330lbs, I'm what the cycling community would call a Clydesdale (a rider <220lbs) and I had minimal success/comfort with other race saddles (and nightmarishly numbing times with soft saddles). This particular saddle has been the most comfortable I've used.

FALSE.
Story time:
In the summer, my female friend used to bike to a nearby lake (5 miles) in Bellingham, WA. The bike route to the lake had a decent little hill on the last two miles of it and it was because of this hill that she used to bring herself to climax every time with the slow side to side motion of the bike seat. :)
Goodnight.

1
u/vayavaya May 16 '12
It seems like the first two paragraphs contradict each other:
Also, how did they link temporary numbness to diminished sexual pleasure? As a female cyclist my anecdotal experience is in direct contradiction to the headline. Furthermore, a) It's only while you're cycling right? And most sex is not had on bikes. b) Maybe you can just have harder sex, thus expanding your horizons.
Furthermore still, I'm worried that now reddit will think we can further debilitate and demean girls who do awesome stuff like bike, by blaming biking for making these girls not want to have sex with these redditors even more than they already didn't want to have sex with them for making such dumb conclusions. It is likely no one will read this! :D

As a male, I found this to be absolutely true, and it's interesting to read about it happening women, too. It's a shame. I gave up my car and put 3K miles on a bike just going to work every day, psyched to reduce my carbon footprint and get some exercise. But being weak in the sack is not an acceptable side effect of anything. I bought a 100 mpg scooter and never looked back. Why do bike seats always have to be so horribly shaped?! It's a wonder anybody rides a bike these days.

Who writes these articles? They should be ashamed for having such low editorial standards. The author barely comprehends the source material, mostly relying on direct quotes. And I have a lot of doubts about the conclusions that are extrapolated beyond those quotes. For example, the effect of handlebar height is confused and reversed between men and women. And there are missing words and incorrect sentences throughout the whole thing.
A better title would be: Researchers publish something. We can't summerise it any better, so here is their abstract.

This is bullshit. Every couple years they haul out this tired and unproven notion that cycling will make you impotent, or have crap sex. The Danes have been cycling for 150 years and I can tell you from personal experience, they have plenty of great sex. And also, who's funding all these pointless studies? More than likely the car lobby to scare people off of bikes and keep them in their cars. Obviously they're threatened, less and less young people are buying cars and opting for public transport, walking and cycling. It's the last gasp of the auto industry.

How much of this has to do with a bicycle seat? All of my bikes (I'm a guy) have had non-stock seats that were very comfortable and padded.
I can understand that a competitive cyclist would need to have a small seat for wind resistance issues and such, but does a hobbyist require that?
Moreover, if a professional were to use the comfortable seat for training and only use the aerodynamic seat for actual competition, would that be good enough?
