I think the best route for males to take would be to try to increase you testosterone naturally. He has also mentioned oregano oil but he did not go overboard with it. I think his main cause of yeast was stress and worry. If you stress or worry about everything as well that is the first thing you need to fix.
He pretty much had every symptom in the book including rash type yeast infection in his groin area. He also had the same type of rash on his hands and neck. That along with thrush, twitching etc.
We were actually talking about this the other day and he swears by exercise (sweating) body building, eating more meat, taking a good probiotic, a clean strict diet to start and then adding stuff in gradually. Get rid of your stress! That sounds like all he really did which doesn't seems like much but he is way less stressed than he used to be and in my opinion is why he is 99% better.
Hope this helps! Get some kefir grains and start making kefir!
Cheers
