Most doctors believe men go through a similar change, andropause, in which testosterone levels rapidly decline. Again, it seems part of evolution's balancing act. Testosterone and Estrogen boost the immune system and prevent certain cancers, but they also seem to accelerate the rate of growth of other cancers.
We also know now that the rate of birth defects among children born to older men (not just women) are significantly higher, so there is another valid evolutionary reason for sex drive in older men to diminish.
