Cycling and Sperm Count(25 posts)

Cycling and Sperm CountRadicalRonPruitt
Dec 4, 2002 10:18 AM
A recent study showed that nine out of ten cyclist who ride more than two hours a day, six days a week is doing damage to the penile region of his body, specifically in the function of producing sperm. On my bike, my saddle is solid and doesn't have a bunch of extra padding to interfere with the nerves in that region. I have never gone numb in that area while riding as well. My concern is that I do wish to reproduce, and don't want to lessen my chances of reproducing. My wife, Gail, is concerned. Has any serious cyclist on this board have problems conceiving?

2 kids...concieved the 1st or 2nd time we "tried". By the way the Asian Chicken pizza was pretty good. Made it the other night.

My counts wayyyyy low. Statistically, I shouldnt have conceived (though I did twice naturally, soley by luck --- thank goodness before i considered any sort of surgery).

According to several urologists i visited, most studies attribute cycling to impotence, not sterility.

Cant say definatively whether cycling was a contributor; but the doctors dont think so. If I recall (though not sure) about 15 or 20 percent of men experience unexplained infertility at some point in their life. Unexplained, becaues they couldnt link it to common factors (like biking)

If youre worried, monitor your count on a regular basis. If it starts dropping appreciably (if your 'normal', you have about 40 million to spare before you'll start having trouble), quit cycling.

What recent study is that? Show me a valid study that found this. I have never seen one. As someone with a graduate degree is statistics, I find most medical research to be really poorly done in terms of inferences drawn. Frankly, I thing this is something Specialized cooked up to sell those goofy saddles with holes in the middle.

I have been riding for years. Fairly seriously the last 12 years. I don't race, but I've been doing 5000-7000 miles per year. I use Selle Italia Flite saddles exclusively. My wife is pregnant. It took us 6 months of trying, but this is not out of the ordinary especially considering she is 34 and I'm 39. I got a sperm analysis done and everything was normal. Motility, mobility, etc. If you're so worried that you're doing damage, get a test done. Most insurance pays for it.

even if insurance doesnt cover, it costs about 100 bucks; less than a new pair of cycling shoes.

Gail to Ron on Christmas day: "Hey honey, I got you a sperm analysis for Christmas. The cup is in your stocking!"

Should of had 3452 kids but only produced 3 kids. The rest just turned into practice sessions

Lets do some math 2 hours X 6 days X 20 miles/hour X 52 weeks=12,480 miles per year

The study doesn't say if there is problems with fertility just sperm count is reduced. It is not a precise study with complete facts so:

Don't worry if you're not logging over 10,000 miles per year
If you are worried about it just jack off a sample and have it stored(for future use)

Well RRP, the post was in jest, plus NOT for you, so..IAmtnbikr

since you are such an astute person and a benefit to the gene pool, THIS is for YOU!
LOL! Enjoy it, it's for YOU! Hope your computer has a nice sound system as well.....
That explains things Ha Ha!!!! nmbigrider

LOL - if he's riding 12,480 miles a year, and she conceives...Kristin

I'd have a paternity test, not a sperm count.
Riding would leave no time to ride! nmbigrider

NOT at the same time. I'm sure I'll get snide comments for that.
The theory is that the raised testical temp. lowers sperm countChainstay

There are a number of valid studies on temperature and sperm count. The little buggers are pretty fragile and a .5 degree rise in temperature kills a lot of them. All this anecdotal stuff about specific conceptions is statistically meaningless crap. Cycling does not necessarily cause sterilty but it can certainly lower sperm count. If you are having difficulty getting her pregnant try not riding for the few days of the month when she is ovulating. If you have a small family it's not that many days off the bike, considering the benefit.

your right, increased scrotal temp kills sperm. Takes about 3 months for the newguys to wiggle properly, you may need to lay off longer than a few weeks.

Recent data point for you Mr. RRP - my wife was a bit concerned also since "it" wasn't happening. So doc says first thing to do is get a sperm count. Wifey feels for sure that all my riding and other activities must be having an effect. Well test results came back and they measured me at 209 Million squiglies per cc - normal is 80 to 120 M/cc and motility was good. This is from someone who used to ride a very hard leather saddle growing up and thought it was perfectly normal for my unit to go totally numb (until a just a few years ago). They then turn their attention to her and found that her hormone levels are quite low. Even when we stopped riding for quite a while it made zero difference. So, in the absence of any hard data one might look at the facts and say that we've been having trouble conceiving, I ride a lot, my unit used to go numb therefore one might conclude that this is the cause. And you'd be totally wrong.

So what's it all mean? First everyone is a bit different. Second it's a small data set. Third everyone worries about all sorts of crap for all the wrong reasons, mostly because they don't have the data. Finally, when it comes to sex, reproduction, and the male organ there is all sorts of misinformation and poorly drawn conclusions. You have to link cause and effect. How come Lance Armstrong isn't sterile - rides a lot, testicular cancer survivor, one testicle, father of three. The other thing men need to learn is that the world does revolve around their penis - it's sad, but true.

Has Lance been tested since his illness? When he knew he was sick, he had a VERY low count, so he saved some off in case they all went away. Since he was never tested BEFORE illness, did illness kill them, or did he already have low counts? My understanding is that his conception was invitro. So he may NOT be fertile (not saying he is or isnt, just my understanding - if someone knows the answer i'd be interested)

Having said that, I agree, too little data anyway to conclusively say either way.

Six years strong on the saddle and two beautiful daughters in thatt time, my bud "Oscar" has no problemo. My boys did suffer at first, they'd complained of numbness. I resolved it by slapping on an WTB SST.98 on my MTB and a flite gel for the road.

Gail has nothing to worry about. If anything cycling gets you primed for action.

although we've managed (at least) all the kids we had in mind (3), I'd hesitate to draw many conclusions from posts on this board (I'd also hesitate to draw many conclusions from a couple of the study reports I've seen recently, but that's another matter).

My own numbers on the usual clinical tests (which I went through, thanks) were absolutely fine--quite a bit above the median--but that doesn't prove much. In fact, we had our own difficulties and delays, and the older folks get, the worse the odds. Clearly, it is possible to ride bikes and have kids. If you are concerned, you can get tested. That will provide some useful, although hardly complete, information. You can get tested again several months later to see if there's any change, but that can get misleading as the intrapersonal variance on these things is pretty damn high. The thing is, the only way to test all the variables in your own personal equation is to actually have the kids.

Don't panic. And good luck.
