Watching pornographic film clips increases the concentration of the anabolic hormone testosterone in the body and lowers the level of the catabolic hormone cortisol and prolactin. Post-adolescent workers at Ergo-log.com read about this in an eighteen-year-old study, in which Scottish endocrinologists got eight male students to watch pornographic videos for twenty minutes. The researchers measured the concentration of hormones in the students’ blood for six hours afterwards.
