Can an STD cause urine odor?

Yes, an STD can cause urine odor.

Urinary tract infections (UTIs), which are commonly caused by sexually transmitted diseases (STDs), can manifest as changes in the urine, including an unusual or strong odor. Some STDs, such as chlamydia and gonorrhea, can cause burning sensations during urination, abdominal pain, and changes in the color and smell of the urine.
