Big Al;330571 said:Evolution has given humans much larger penises than our primate relatives, but it's taken thousands to milloins of years for these changes to take effect. If you're interested in data of the evolution of the human penis, check out this thread: http://www.lpsg.org/116182-evolution-and-the-penis.html
The latest data shows that average testosterone levels are decreasing likely due to pollutants in the environment. We're likely to see average penis sizes decreasing over time or maybe even widespread sterility and/or impotence if this trend continues. Needless to say that this is a very scary trend that does not bode well for the human race <
"Studies in the 1940's showed the average testosterone level to be 300 ng/ml higher than for men today." http://www.usdoctor.com/testost.htm
Men's testosterone levels dropping, study says
Testosterone levels down in last 20 yrs
American Testosterone levels dropping like rain
Good find!
Something to touch on,
Today many many food especially in America, are riddled with Soy and Soy Lechiten, everything from Sauces, to Cereals, even Whey proteins itself. There are studies that show Soy hinders testosterone greatly taken over a long period of time. That coupled with the fact that still a great fraction of the population do not train with heavy weights (which boosts testosterone greatly especially heavy lower body excersices, squats deadlifts, cleans etc).
My father was a barber / hair stylist for 30 plus years, its also a known fact that Male Pattern baldness has been on the rise since the 60's.
Food has a huge role in all of this. Eat fresh clean food you should be okay stay away from the processed stuff.
