...für Vereiterung

autsch!

"suppuration (or diapyesis) / fungous affect of the glans (or head of the penis)"

The terms for "Vereiterung" are from "UNSELD Medical Dictionary, 11th Edition" Wissenschaftliche Verlagsgesellschaft Stuttgart

As to "Verpilzung" I took it as "Pilzbefall" and translated it "fungous affect". In my understanding "Verpilzung" is a "Pilzbefall" that has spread quite far already. Maybe you even want to say "wide spread fungous affect".

There is a term "fungaemia (Brit) or fungemia (US)" identifying a fungous disease, but I don't know and could not find out what exactly this is.

Should you settle for "Pilzbefall" please do not translate it with "fungal attack"!!! This is a technical term, relating especially to wooden structures.

as bad as it may sound, but I think "cock cheese" is what you are looking for.

falls beides zutrifft und du nicht alternativ einen der beiden Termini suchst

"pyetis" =>"pyesis", if anyone would know what it meant. Use "suppuration".

"fungous affect" ???
>Maybe you even want to say "wide spread fungous affect" ... No, I don't think you do.
And "fungaemia" = the presence of fungi in the blood.

go with b.f's suggestion if you want a technical combination.

unhygienic, but not necessarily infected

@ Marianne: I agree with what you are saying. When I wrote my comment, I was looking at that anti-Nazi comment under #3 only where my translation suggestion would have fitted perfectly well. That okay with you?
