In this study it was estimated that about 1 in every 20 cases of HIV could be avoided if gonorrhea and chlamydia infections are detected and promptly treated.

Having gonorrhea and chlamydia in the cervix or rectum increases your risk of HIV if you gets exposed to this virus.

Of course, most rectal and cervical (in the cervix) infections due to chlamydia or gonorrea are usually silent, with no symptoms at all – that is to say, that if you get infected you would probably not know

But if you get the tests done that are relevant to your own sex life (oral, vaginal or anal sex) and get treated with antibiotics if there gonorrhea or chlamydai are detected  WOULD AVOID ABOUT 1 IN EVERY 20 CASES OF HIV according to this study. Or in other words, if you were then to get exposed to VIH your risk of catching it would be lesser.
