My boyfriend and I have been together for over three years, and we've just decided to start trying for a baby. He loves biking. He had been using his bike as his primary mode of transportation until last fall/winter when he developed problems with his knees from the excessive biking; then he bought a car and primarily uses that now. However, he just got a job that's very close to where he's living right now, and he's considering using his bike to save on gas. My concern is that this might inhibit our chances of conceiving.
When I first met him in June of 2008, he hadn't been doing a lot of biking. He started biking a lot in order to come see me (about 8 miles away). The first month we were together, he said he would experience numbness and tingling in his genital area after biking, so he immediately got a better bike seat. It's a lot wider and cushiony, and it dips in the middle (I guess to cradle the balls). He says he hasn't had the numbness/tingling since getting that seat years ago and that he doesn't even sit on his balls or anything. Anyway, is there any chance that biking affects fertility? He definitely has no erection problems, but we've never tested his sperm count. Any help is appreciated!
