Is the lack of interest in women a cause or a consequence? I am no expert but I believe that libido can be impacted by hormones, etc. so that a lack of libido may be a symptom of deeper biological issues that have, in fine, a negative impact on life expectancy. Conversely, an active libido may be a 'symptom' of a generally healthy individual.
