That only happens if vaginal gonorrhea is left untreated. oral does not cause those problems. And oral gonorrhea is uncommon so that is why it is not tested for.
I read somewhere though that it can cause heart problems, pelvic problems and infertility. Its really scaring me actually! I dont understand why my local std centre doesnt test for that.
Well that is how oral gonorrhea would be diagnosed btu I see no real reason to have it done. Most of the time oral gonorrhea will cure it's self after a couple of months. And getting an oral STD is not all that common. So you can if you want, but don't see it as necessary.
