For being a doctor...you're certainly not helping with the technical aspect of things. Of course I know what to do with it. I want to know if semen goes stale? If it does...how long before than happens? I would CERTAINLY consider this a HEALTH issue. It is no different than someone accumulating an amount of ingestable substance, no matter how "weird" it might seem to you (i.e. Snot, Milk, Pond Water).
