High intensity & high volume cycling appears to decrease sperm quality. This is pretty old news, and something all male cyclists are aware of I assure you. But by how much?
Recent research in this area has indicated that Triathletes performing over 300km per week had less than 4% of normal sperm – an amount that would mean they are
considered to have significant fertility problems
I guess one question is are these effects reversable, and if so then perhaps this is something the Natural Fertility should be made aware of…

There is some good research into the problem – a study in the US on the effects of prolonged riding among a group of cycle patrol officers showed no effect on sperm count but indicated erectile dysfunction which increased the longer the riders spent in the saddle. The research is available on ECD’s website (www.ecdsports.com)

Was that the study where they trialed a new type of bike seat?
