Sometimes it’s musky. Other days, it’s slightly tangy, metallic, or unfamiliar. The vagina is one part of the body many women are taught to monitor obsessively, yet understand the least. From advertisements promising “floral freshness” to whispered conversations that equate scent with shame, vaginal smell has long been surrounded by misinformation, silence, and unrealistic expectations.
Let’s be clear from the start: having a vaginal scent is normal. In fact, it’s expected. The vagina is a living, self-regulating organ with its own microbiome, and like every other part of the human body, it has a natural smell that can change depending on internal and external factors.

“A healthy vagina is not odorless. Any narrative that suggests otherwise sets women up for unnecessary anxiety and harmful practices,” says Dr. Maduemezia K., a medical doctor Elowell Max spoke with.
Understanding vaginal smells will help you recognize what’s normal, what’s temporary, and what may require medical attention. Here’s a detailed breakdown of common vaginal smells, what causes them, and what they usually mean for your health.
Contrary to popular belief, there is no single ‘normal’ vaginal smell. Every woman’s body chemistry is different, influenced by hormones, genetics, lifestyle, hygiene habits, diet, sexual activity, and even stress levels.
The vagina maintains a naturally acidic environment, typically between pH 3.8 and 4.5, which helps protect against harmful bacteria and infections. This acidity alone contributes to a mild scent that many women describe as musky or tangy.
“Your vaginal scent can change across different phases of life, puberty, ovulation, menstruation, pregnancy, and menopause. These changes are physiological, not pathological,” explains Dr. Maduemezia K.
Problems usually arise when there is a sudden, strong, or persistent change in smell, especially when accompanied by symptoms like itching, burning, pain, or unusual discharge.
1. The Fishy or Sharp Smell
A fishy vaginal odor is one of the most commonly reported concerns among women—and for good reason. This particular smell is often associated with bacterial vaginosis (BV), a condition caused by an imbalance between good and bad bacteria in the vagina.
BV is not a sexually transmitted infection, but sexual activity, douching, and frequent changes in vaginal pH can increase the risk. Another possible cause of a fishy smell is trichomoniasis, a sexually transmitted infection caused by a parasite.
Common accompanying symptoms may include, thin, grayish or white discharge, vaginal itching or irritation, and burning sensation during urination. Other symptopms to look out for include pain or discomfort during sex
“A fishy smell is a red flag, especially if it persists. While BV is common and treatable, ignoring it can lead to complications if left unmanaged,” warns Dr. Maduemezia K.
Medical treatment, usually antibiotics, is necessary to fully resolve these conditions. Home remedies or scented products often worsen the problem by further disrupting vaginal pH.
2. The Damp or Sweaty Smell
A damp, sweaty, or slightly sour smell is often linked to perspiration and moisture retention in the genital area. The vulva contains sweat glands, and when sweat is trapped—especially in tight clothing or damp underwear—it can create an environment where odor-causing bacteria thrive.
Common triggers for this type of odor often relate to moisture and limited airflow around the vaginal area. Wearing damp or poorly dried underwear, remaining in sweaty clothes for extended periods, or choosing tight, non-breathable fabrics can trap heat and moisture against the skin. In hot and humid weather like we have in Nigeria, this effect is even more pronounced, creating an environment where sweat accumulates easily and odor-causing bacteria are more likely to thrive.
“Moisture trapped around the vaginal area doesn’t just cause odor—it increases the risk of fungal and bacterial growth,” says Dr. Maduemezia K.
The solution is often simple: opt for breathable cotton underwear, change out of wet or sweaty clothing promptly, and allow adequate airflow whenever possible.
3. The Metallic or Coppery Smell
A metallic or copper-like smell is particularly common during or immediately after menstruation. Menstrual blood contains iron, which naturally produces a metallic scent when exposed to air.

This smell may also occur after sexual intercourse, as semen has an alkaline pH that can temporarily alter the vagina’s acidic environment.
“A metallic smell linked to menstruation or sex is usually harmless and self-limiting,” explains Dr. Maduemezia K. As long as the smell fades within a short period and is not accompanied by pain, itching, or abnormal discharge, it is not considered a health concern.
4. The Sour, Tangy, or Yoghurty Smell
A mildly sour or tangy smell, often compared to yoghurt, kefir, or fermented cabbage—is generally a sign of good vaginal health. This scent comes from the presence of Lactobacillus bacteria, which play a crucial role in maintaining vaginal balance.
These beneficial bacteria produce lactic acid, keeping the vagina acidic and protecting it from infections.
“When Lactobacillus dominates the vaginal microbiome, the resulting scent may be tangy or fermented—but that’s actually a good sign,” notes Dr. Maduemezia K.
Women experiencing this smell without discomfort should not attempt to “fix” it. Overwashing or using harsh products can disrupt this healthy balance.
5. The Rotten or Extremely Unpleasant Smell
A strong, foul, or rotten smell is often linked to menstrual hygiene issues. Leaving sanitary pads or tampons on for too long allows blood and bacteria to accumulate, leading to unpleasant odors.
Other possible causes may stem from hygiene lapses or underlying medical issues. Forgetting a tampon inside the vagina can lead to a strong, unpleasant odor as bacteria build up over time. Reusing unwashed or dirty underwear may also reintroduce bacteria and old secretions to the area, worsening the smell. In some cases, a persistent or severe odor can signal an infection that requires prompt medical attention and should not be ignored.

“Retained menstrual products are more common than people think and can cause significant odor and infection if not addressed quickly,” says Dr. Maduemezia K.
If a foul smell persists despite proper hygiene, or is accompanied by fever or pain—medical evaluation is essential.
The Role of Hygiene
Many women assume that frequent washing, douching, or scented products will improve vaginal smell. In reality, these practices often do more harm than good.
“The vagina cleans itself. Introducing soaps, antiseptics, or fragrances internally disrupts its natural defense system,” warns Dr. Maduemezia K.
Gentle cleansing of the external vulva with water or mild, unscented soap is sufficient. Internal washing is unnecessary and discouraged.
While scientific evidence is limited, many women report subtle changes in vaginal scent linked to diet. Foods such as garlic, onions, asparagus, alcohol, and heavily spiced meals may influence body odor, including vaginal scent.
“Diet affects overall metabolism and body secretions. Staying hydrated and maintaining a balanced diet supports vaginal health, even if changes in smell are subtle,” explains Dr. Maduemezia K.
Probiotic-rich foods like yoghurt may help maintain healthy vaginal flora, though they are not a replacement for medical treatment when infections occur.
When to See a Doctor
While variation in vaginal smell is normal, seek medical attention if you experience:
- Persistent fishy or rotten odor
- Unusual discharge (green, gray, or frothy)
- Itching, burning, or pain
- Bleeding outside your menstrual cycle
“Smell should never be your only indicator of health, but persistent changes deserve professional evaluation,” advises Dr. Maduemezia K.
Your vagina does not need to smell like flowers, candy, or perfume to be healthy. It needs balance, care, and understanding. Normalizing conversations around vaginal health empowers women to recognize when something is wrong, and when everything is perfectly fine.
