Do all STDs have an odor?

Not all sexually transmitted diseases (STDs) have an odor. Some STDs, such as chlamydia and gonorrhea, do not typically produce any noticeable symptoms or odors. Other STDs, such as trichomoniasis, may cause a fishy odor, while bacterial vaginosis can cause a foul-smelling discharge. However, the presence or absence of an odor is not a reliable indicator of whether or not someone has an STD. It is important to practice safe sex and to see a healthcare provider if you have any concerns about STDs.
