I’ve been cycling seriously since I was 12 years old, I’ve ridden hundreds of thousands of miles. When I was in my 40’s my wife had me see a fertility specialist even before she wanted to get pregnant, so I went through the entertaining experience of providing the clinical with a sample. My count was in the 90th percentile, I joked with my wife that she might get pregnant if she stood too close to me. When we went through the motions of getting pregnant, it went perhaps a little too easily, and a year later we had our first kid. Perhaps I’m some kind of exception, but if more than 30 years of riding bicycles, motorcycles, and even horses have an effect on sperm count, in my case it may have helped.
