Well, I dunno about that. We seem to be missing some data.
Were the subjects of this study watching X-rated videos or Sesame Street? If X-rated, what were these guys doing immediately after (or during) the videos? And how did the researchers get the sperm out of these guys to count it, including the ones who weren't watching TV? And what were the guys looking at while their sperm was being contributed to the counters?
Y'know what I think? Sloppy, sloppy science reporting is what.
