wait... this thread is 24 pages and its just about celery seed!? it must be working then, eh?
personally, i used to combine celery with garlic and meat and my testo went crazy! that was in my 20s though, so im kind of pessimistic it really does have a significant effect in general.
now days, what makes me sex driven lunatic is basically taking opiates for few days and then taking few days off. its 100% science fact opiates block, and lower sex hormones, BUT once you get off them, sex hormones shoot through the sky. the trick is to never do opiates for too long otherwise you might lower sex hormones so much, rebound effect will be longer and slower.
