I’d be surprised if it made a dent… I’d probably first check the numbers on this… you are saying that because men can get their testosterone up even later in their lives, they either cheat, get sexually frustrated, or less likely to put up with their wives behavior? Interesting theory, but I would be surprised if the numbers supported this pet theory.

Men with higher testosterone has been linked to cheating in various studies--honestly I thought this was common knowledge. And treatments for "low t" (targeted at middle-aged and older males) have been more and more common over the past few decades. I guess it just seems fairly plausible.
