I was concerned about this, so I actually went to a fertility clinic myself and got a semen analysis. My sperm count came out low but "within range" and the motility was low and "out of range". I am a healthy normal guy, I exercise 6/7 days a week, am not obese, don't drink much, and eat pretty healthy generally. My low "in range" count would have been considered extremely low and out of range a generation ago. So anecdotally, I think that something is not right here.
Read the book "Countdown". The author goes into great detail all of the reasons that modern life is putting downward pressure on sperm quality and quantity. The author, Dr. Swan, is a leading expert in the field. The book is really good, and pretty scary.
