‘Unfortunately, this doesn’t display the results clearly enough’

The 80s were all about getting pumped up in various ways, it's slightly interesting that the first medical treatments for erectile dysfunction turned up in 1983.

That it was in the 1980s treatment was developed, with phentolamine and papaverine followed by the massive impact that viagra had, possibly with an aging male population in mind, seems significant. Or that the later 80s/early 90s was characterized by  sex-killing drugs like E. There may have also been more older male focused movies (City Slickers came out in 1991 shortly after viagra was patented, there were probably more) but that's only speculation.
