I expect sexual interest is just a weak proxy for general health - sexual function(including libido) relies on cardiovascular, endothelial, autonomic function, is impaired by under/over-weight, dysglycemia, sleep disordered breathing, poor anaerobic fitness.

I agree. Another interesting counter-point study is the study that showed that eunuchs live longer (14 to 19 years longer)
