The Most Common Vaginal Odors (And Why They Happen)
Your vagina is home to sweat glands and billions of bacteria – and that’s normal! It’s not supposed to smell fresh or flowery, and different scents can vary based on factors like your menstrual cycle, hormones, personal vaginal flora, and more. Here’s a breakdown of a few common vaginal odors and why they happen so that you can stay informed.
Tangy or Fermented Smell
A slightly tangy or sour aroma, similar to fermented foods, is normal. This is due to the presence of the “lactobacilli” bacteria that dominates most healthy vaginas. This bacteria helps maintain an acidic environment, protecting against the growth of harmful bacteria.
Coppery “Penny” Smell
This can usually be attributed to the presence of blood from menstruation or minor cuts during activities like sex, especially if there’s vaginal dryness. Typically, it’s nothing to worry about unless you notice bleeding unrelated to your period or experience significant itching or discharge.
A Sweet Smell
Some vaginal bacteria can produce a slightly sweet smell. However, if the smell is very sweet and accompanied by discharge that looks like cottage cheese, it may indicate a yeast infection, particularly if you also notice burning, dryness, and itchiness.
Body Odor or Sweaty Smells
There’s a high concentration of sweat glands around the outside of the vagina on the labia majora. These “apocrine glands,” similar to those in the armpits, can produce fluid that interacts with bacteria to create a distinct “body odor” aroma. This is generally normal and nothing to be concerned about.
Pungent “Fishy” Smell
An unusual vaginal odor sometimes described as “fishy” can be due to the chemical trimethylamine, which is responsible for the smell of rotting fish. This odor can result from bacterial vaginosis (BV), which is caused by an imbalance of bacteria, or from trichomoniasis, a common curable STI. If you notice a strong, unpleasant fishy odor, it’s best to consult a healthcare provider promptly.
Still Concerned? Talk to a Professional!
Some vaginal odors are completely normal, but if you experience additional symptoms or notice an unusual odor that persists, consider seeing a healthcare professional for peace of mind. It’s always a good idea to stay proactive about your reproductive health.
