It can be uncomfortable to talk about intimate health issues, but paying attention to changes in odor is important. A fishy smell in the genital area is not something to ignore.
While occasional mild odor can be normal due to sweat or hygiene habits, a persistent or strong fishy smell often signals an underlying issue that requires attention.
Common Causes of a Fishy Smell
1. Bacterial Vaginosis (BV)
- The most common cause in women.
- Occurs when the natural balance of bacteria in the vagina is disrupted.
- Symptoms include a fishy odor, thin grayish discharge, and sometimes mild irritation.
- Not usually sexually transmitted but can be triggered by douching, new sexual partners, or hormonal changes.
2. Trichomoniasis
- A sexually transmitted infection (STI).
- Caused by a parasite that leads to strong odor, yellow-green discharge, and itching.
- Requires medical treatment with antibiotics.
3. Poor Hygiene or Sweat
- Sweat glands in the groin area can create odor when mixed with bacteria.
- Tight, non-breathable clothing can make it worse.
4. Menstrual Products
- Forgotten tampons or pads left in too long can cause foul odors and increase infection risk.
5. Other Infections
- While less common, urinary tract infections (UTIs) or yeast infections may contribute to unusual odors (though yeast infections are more often yeasty than fishy).
What You Can Do
- See a doctor: If the odor is persistent or accompanied by itching, burning, or unusual discharge.
- Avoid douching: It disrupts natural vaginal flora and can make things worse.
- Wear breathable cotton underwear: Helps reduce sweat and bacterial growth.
- Practice safe sex: STIs can be a cause and should be ruled out.
- Good hygiene: Daily gentle washing with warm water (not harsh soaps) keeps the area clean without disturbing its natural balance.
For Men
Although less common, men can also experience unusual genital odors due to poor hygiene, infections, or STIs. Persistent odor should be checked by a healthcare professional.
The Bottom Line
A fishy smell in your private parts is often a signal from your body that something is off—most commonly bacterial vaginosis or an STI. While it may feel embarrassing, seeking medical advice is the best step. With proper care, the issue is usually easy to treat, and your peace of mind (and health) is worth it.
