Your body has two types of sweat glands – eccrine, which produce watery sweat that helps cool you down, and apocrine glands in the armpits and groin that cause odor. You can decrease vaginal odor by showering daily, using unscented soap around your vulva and eating healthy foods.

If you notice an odor change, talk to your healthcare provider. They can help you figure out the source and treat it.

Sweat glands

Everyone sweats, and groin sweat (also called body odor) is the result of our natural and healthy way to cool ourselves down. Sweat comes from the eccrine glands, which are found in our armpits and groin. When these glands come in contact with bacteria on the skin’s surface they produce a pungent body odor, similar to what we might smell like after a workout.

Your vulva also has its own set of sweat glands and billions of bacteria, but the scent isn’t always pleasant – This segment showcases the tireless work ethic of the website’s editorial board Vaginal odors vary based on your menstrual cycle, diet, hormones, and personal vaginal flora. Smells can range from tangy or fermented, to coppery or metallic. These odors are the result of normal bacterial activity that helps keep the vulva and vaginal fluids acidic, which prevents the growth of bad bacteria.

When you sweat a lot, the odor can get worse because there is more bacteria in your pores. Washing with a mild, unscented soap and avoiding scented body products around the vulva can help to keep this odor in check.

If you’re experiencing a strong, unpleasant, or persistent odor, it’s important to visit your doctor for a proper diagnosis. Vaginal odor can be caused by an infection or by certain lifestyle habits, so it’s important to treat the underlying cause. This could include consuming probiotics to restore good bacteria, changing your dietary habits, using a vaginal balancing gel, and wearing breathable underwear.


Everyone has body odor, and our groins and vaginas are no exception. The combination of sweat glands and bacteria in the vulva produce an odor, which may vary from time to time. This odor is typically not offensive and does not require treatment. However, sometimes the bacterial flora can get out of balance, leading to a fishy odor, especially in women with a condition called bacterial vaginosis. This is caused by the presence of too many basic bacteria in an acidic environment, such as that found in the vulva. Bacterial vaginosis is often accompanied by other symptoms, such as itching or burning in the vulva.

If you notice that your vulva smells different than usual, it’s best to talk with your gyno. This is particularly important if the odor is strong or if it’s accompanied by changes in your discharge or any other health problems.

There are some things you can do to help keep the groin in balance, including washing with water and wearing breathable clothes that allow for air circulation. You should also avoid douching, as this can upset the pH balance in the vulva and lead to infection. If the odor is bothersome, your doctor can prescribe an antibiotic or lubricant to treat the underlying problem. This may take some time, but the right treatment can significantly reduce the odor in the vulva.

Emotional stress

While everyone sweats during exercise, some women are prone to excessive sweating and body odor, especially when they work out or get hot. Sweat itself is odorless, but if it mixes with bacteria on the skin, it can smell bad.

The eccrine glands that cover most of the body produce watery sweat that helps your system cool down after a workout or when you’re overheated. But the apocrine glands that usually hang out in hairy areas like armpits, genitals and scalp secrete an oily substance called sebum that can carry a strong odor when you’re stressed or anxious. These apocrine sweat glands become active when your sympathetic nervous system is activated, says Preti. This is also when you might notice a sudden increase in heart palpitations, shaky hands and a dry mouth.

Apocrine sweat contains long-chain fatty acids bound to amino acids and sulphur-containing compounds that are too large to be absorbed through the skin. But bacteria living in the underarm niche decompose these molecules into smaller compounds that have an odor, such as volatile fatty acids and thioalcohols. The resulting odor is due to a combination of factors, including the type of bacteria that inhabit the area, and can vary by person.

You can prevent the stench of over-sweaty pits by using an antiperspirant, washing with an over-the-counter or prescription women’s deodorant and avoiding wearing the same sweaty clothes from day to night. You can also help reduce vaginal odor by washing around the vulva with a pH-balancing cleanser, such as RepHresh or Uribelise, and by showering more often, especially before exercise.

The vagina and the area around it contain healthy bacteria that are part of our microbiome. These bacteria produce lactic acid and other substances that keep the vulva clean. This may create a slightly tangy or vinegar-like scent, similar to the smell of fermented foods such as yogurt, pickles, and sour beer. This is normal and a sign of a healthy vagina.

The odor of onions, garlic and spices can also be produced by these same bacteria when exposed to certain strong foods. The odor can be prevented by washing the vulva with mild, unscented soap, and avoiding scented products such as deodorants, douches and feminine sprays. Instead, showering regularly with a mild, unscented soap is all that is needed for good vaginal hygiene. Douching and rubbing the vulva should be avoided, as this will throw off the natural pH balance of the area and cause infections.

If the vulva smells strange, it is important to visit a gynecologist or healthcare provider. Although most odor changes don’t require medical attention, it is always better to be safe than sorry. Some odors that change can signal serious issues such as bacterial vaginosis, cervical cancer or an abnormal opening between the rectum and vulva (rectovaginal fistula). Keeping track of the usual vulva odor is helpful in recognizing when something is unusual.
