Interesting study but no way to know how each man was doing on fitness, exercise, eating habits, stress, other medical conditions, medications, and other factors that affect sex drive and erection abilities. The T levels are not proven to cause sexual frequency alone, with all other variables not having been kept constant and uniform in all the study men. Too many variables going on in these study men to credit just one factor, T levels, with causing sex amount.

But it sure needs more study and knowledge to do men the most good on T levels, replacement levels, and how T works best in men s bodies. Glad to see someone trying to learn more about T levels and aging and older men enjoying optimal sexual abilities.

Too many backward drs think sex is only for younger men to enjoy and for breeding. As if older men and non breeders don t have the right to enjoy sex fully and without any breeding intent ! Sex is not just for the young and the very short time most men are actively impregnating to have kids ( maybe a few months of cycles inseminated per baby or less for most fertile men to achieve each impregnation )..

Sex should be fully enjoyed from puberty until death from old age and optimally facilitated at maximum levels in all males of every sexual age by drs and our culture. It should be a recognised right and admirable life pleasure for all males to enjoy.

T is one factor and the body condition for itself is also an very important factor.

Thats not new, thats normal knowledge!
