Not exactly sure but I think the Candida threads grow through anything their way. When I got Candida sexually it was at first penile candidiasis, then the threads grew through the tissues into the intestine and from there elsewhere in the body. The threads probably go through the prostate and everything else in the reproductive system putting holes in it.
Also Candida causes leaky gut, and autoimmune disorders. The liver has to struggle with undigested food in the bloodstream as well as any kind of toxin that's supposed to be just in your intestine - it's in your blood. Imagine taking a syringe full of filthy toilet water and injecting it into your arm - pretty much the same effect. So the liver is stressed. I have read that a stressed liver causes ED.
