Causes
By Mayo Clinic staffBacterial vaginosis, or overgrowth of normally occurring vaginal bacteria, is the most common cause of vaginal odor. Some sexually transmitted diseases may cause vaginal odor. A retained or forgotten tampon may eventually cause a vaginal odor.

- Poor hygiene
- Retained or forgotten tampon
- Trichomoniasis
