so um lying was excluded um being fous here but um yeah how was this study done I mean pretty incredible study um and the results are I don't know if they're surprising or not I I first I thought oh this is surprising but the results were only surprising in light of what you were talking about earlier about sperm and testosterone levels I think um I'll let you describe the study now rather than than giving people the punchline here yeah so I mean the origin was that we were looking at we wanted to know average lengths for another project that we were doing and you know going down the rabbit hole this has been reported for decades you know there's different reasons that people have reported P length you know sometimes they do it uh just on volunteers again to sort of get the average lengths of different populations sometimes it's done pre and pro- surgically to try and understand what changes would occur um so we just sort of called the literature found data on 55,000 men all over the world um and wanted to see if there was a you know sort of a Time pattern with that and similar to your hypothesis we assumed based on all the other data that we would likely see a decline you know whether it be you know chemical environmental exposure but if nothing else if we're getting bigger you know the functional penile length should decline because you know the super pubic fat pad will get a little bit bigger and so we'll kind of lose penile length with that and so much to our surprise the super pric F pad excuse me um being the pad of fat directly over the penis right right and so you know if that gets bigger that'll necessarily compromise penal length but you know as you alluded to what we found is actually the opposite that um that penises were getting getting longer with time so how it's measured measured differently so one of our inclusion criteria was that all the study had have measured sort of in an office sort of in a clinical setting so whether it be a you know a clinician or whether it be a researcher that actually did it
