It can cause impotence, but mainly if you do it a certain number of hours a day. I wouldn't worry if you do it a few times a week.
I think i read that 15-30mins 3 days a week is enough to severely affect your fertility, and, over a long period of time, full impotence.
Most cycling saddles don't support your 'sit bones' so most of the pressure of your weight is focused on more sensitive areas, reducing the blood flow to your sex organs. You can get special supportive seats (about £30ish) which look a bit weird, but are specially made to protect your fertility and be more comfortable. Also, gel and spongy saddles can be even worse than normal saddles at causing infertility as you sink into them, putting more pressure on your more intimate areas.
I thought it was more the longer distance road riders and mountain bikers that get it, due to sitting on the saddle for such long periods, if not I better be more careful when riding :s
Oh blimey. I bike about 4 miles to work each day (well, for the nest 5 weeks) and then most of the times 3 miles to college. Still, most of its road cycling, so not to bad I spose. I'll have a look at one those saddles though, I use a super thin racing saddle :s not good I daresay.
1-1:30 4-5 days a week + 30 mins every morning paper-round, the former being jump/mtb.... oh crap, does anyone have a link to an article on this?
Ye gods! Ive just googled for 'anatomical saddle' and the cheapest one ive found is £60!! Would it just be cheaper to *** in a jar and freeze it instead?
I was under the impression that Professional Cyclists all ended up quite the opposite...crazy horny with the sexual appetite of a wolf surrounded by *****es on heat. Did Marco Pantani lie to me?
edit|| I like the way that sounded as if Marco Pantani told me he was a horny *******. I read it :s
On the other hand, my grandad biked to school and work for about 40-50 years, and hes got 4 kids.
