Garlic, plain yogurt and applesauce are the best home remedies for internal fungus infections. Remember that every time you have taken antibiotics, the side effect is a yeast (fungus) infection - male or female. The anti-fungal medicines have their own side effects too - including limiting exposure to the sun.
My dog has been in the vicious circle of staph infection and antibiotics to fungal infection to staph infection most of her life. Recently I started giving her plain yogurt and applesauce and she is finally starting to end the cycle. (Most vets don't recommend any garlic for dogs and cats.)
