Could PCOS be caused by parasites? Since cysts are natural, I still menstruate and I lack most of the other defining elements of PCOS, trying to figure out what could be the cause. In my culture, infertility is usually linked to parasites and were I living in the Caribbean herbs would be given. My ND has tested me for parasites but I was sick at the time and not strong enough for a parasite cleanse. Here of course BC is the way PCOS is treated and I can't convince my doctor that parasites could be the cause. Is the Black-Walnut /artemesia/clove combo something that could work for cleansing the ovaries? What kinds of parasites could live in the ovaries??
