Use it or lose it and sexual intercourse

A recent Finish study evaluated the effect of frequency of sexual intercourse on risk of subsequent erectile dysfunction.  The study was based on written interview data.  A sample consisting of 989 men aged 55 to 75 years (mean 59.2 years) was followed over a 5 year period.  All men were free of erectile dysfunction at study baseline.  The major finding was that the risk of erectile dysfunction was inversely related to the frequency of intercourse and that regular intercourse protects against the development of erectile dysfunction in men in this age range.  Men reporting intercourse less than once per week at baseline had more than twice the incidence of erectile dysfunction compared with those reporting intercourse at least once per week, that is 79 versus 33.  This is yet another example of use it or lose it when body capabilities of older people are concerned.

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career. I have been at this part-time for well over a decade, and in 2007 this became my mainline activity. In earlier reincarnations of my career. I was founding dean of a graduate school and a university professor at the State University of New York, a senior consultant working in a variety of fields at Arthur D. Little, Inc., Chief Scientist and C00 of Mirror Systems, a software company, and an international Internet consultant. I got off the ground with one of the earliest PhD's from Harvard in a field later to become known as computer science. Because there was no academic field of computer science at the time, to get through I had to qualify myself in hard sciences, so my studies focused heavily on quantum physics. In various ways I contributed to the Computer Revolution starting in the 1950s and the Internet Revolution starting in the late 1980s. I am now engaged in doing the same for The Longevity Revolution. I have published something like 200 books and papers as well as over 430 substantive.entries in this blog, and have enjoyed various periods of notoriety. If you do a Google search on Vincent E. Giuliano, most if not all of the entries on the first few pages that come up will be ones relating to me. I have a general writings site at www.vincegiuliano.com and an extensive site of my art at www.giulianoart.com. Please note that I have recently changed my mailbox to vegiuliano@agingsciences.com.
