Many women notice an occasional “fishy odor” from their intimate area. While uncomfortable, it isn’t always serious. Sometimes it appears without a clear cause and may fade on its own with basic habits like showering regularly and changing into clean underwear.
When the smell persists despite good hygiene or comes with itching, pain, or unusual discharge, it can signal a medical issue. One of the most common causes is “bacterial vaginosis (BV)”, which happens when the natural balance of vaginal bacteria changes. Symptoms often include thin gray or white discharge, itching, and a strong odor “especially noticeable after sex.” BV requires antibiotics to clear properly.
Not all odors mean infection. Sweat trapped by tight clothing or poor airflow can create unpleasant smells. Wearing breathable fabrics and maintaining gentle hygiene often helps in these cases.
Another possible cause is trichomoniasis, a sexually transmitted infection caused by a parasite. It can also lead to odor and discomfort and “must be treated with prescribed medication—not home remedies.”
A forgotten tampon is an often-missed cause. This can create a very strong, rotten smell and should be dealt with quickly.
To reduce odors, use warm water and mild soap externally, avoid douching and scented products, wear cotton underwear, and practice safe sex. If symptoms don’t improve, “consulting a gynecologist is the best course of action.”
