Você fica, em média, com o pau duro por 90 min a cada noite de sono


Scientists have determined that the average 13- to 79-year-old penis is erect for about 90 minutes each night, or 20 percent of overall sleep time. With your brain cycling between the four sleep stages, your “sleep-related erections” appear at 85-minute intervals lasting, on average, 25 minutes. (It’s true; they used a stopwatch.)

Tá na Scientific American.
