Many women encounter vaginal moistness and odor at different times, often causing discomfort and concern. It's essential to delve into the underlying causes of these symptoms to discover effective solutions and preventive measures.

I. Physiological Causes

1. Natural Secretions: The vagina naturally produces secretions that aid in moisture maintenance and self-cleansing. These secretions are typically clear or white and lack a noticeable odor under normal conditions. Variations in quantity and consistency occur throughout the menstrual cycle, with increased thinning and abundance during ovulation to facilitate sperm passage and fertilization.

2. Hormonal Fluctuations: Hormonal changes, such as those during puberty, menstruation, pregnancy, and menopause, can influence vaginal secretions. Significant shifts may lead to increased secretions accompanied by mild odors.

II. Pathological Causes

Various pathological conditions contribute to vaginal moistness and odor, characterized by distinct smells:

1. Fishy Smell: A fishy odor often indicates bacterial vaginosis (BV), caused by an overgrowth of anaerobic bacteria. BV is common and presents with increased discharge that intensifies with alkaline substances like soap. Symptoms include vaginal discomfort, itching, and external dampness.

2. Foul Odor: Infections like trichomoniasis or anaerobic bacterial infections can produce a strong, unpleasant smell. Severe reproductive tract infections, such as endometritis or advanced cervical erosion, may also cause foul-smelling discharge, necessitating medical evaluation. Bright red discharge in elderly women might signal malignant tumors.

3. STIs: Sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and genital herpes contribute to vaginal moistness and odor. These infections often manifest with abdominal pain, painful intercourse, and painful urination, requiring prompt medical attention for diagnosis and treatment. For treatment, herbal medicine Fuyan Pill can be selected.

III. Poor Habits

1. Lifestyle Factors: Prolonged use of tight synthetic clothing restricts airflow, elevating moisture levels and fostering bacterial growth in the genital area. Over-cleansing with harsh agents disrupts vaginal pH balance, upsetting microbial flora and leading to odor. Unhealthy lifestyles weaken immune defenses, compromising vaginal self-purification and increasing vulnerability to infections.

2. Dietary Habits: Consumption of spicy, greasy foods or excessive sugars can disrupt hormonal balance and vaginal pH, contributing to abnormal odors.

3. Sexual Practices: Unsafe sexual behaviors, multiple partners, and inadequate contraceptive use heighten the risk of STIs, resulting in abnormal vaginal secretions and odor. Condom use, sexual hygiene, and regular health checks are crucial preventive measures.

IV. Preventive Measures

1. Hygiene Practices: Daily underwear changes and gentle cleansing with water maintain vaginal hygiene. Increased cleaning frequency during menstruation helps keep the area dry and sanitary. Partners should practice pre- and post-coital hygiene to prevent bacterial transmission.

2. Clothing Choices: Opting for breathable cotton underwear and avoiding tight garments promotes genital airflow, reducing bacterial growth. Regular physical activity and avoiding prolonged sitting further mitigate infection risks.

3. Weight Management: Maintaining stable weight prevents excessive strain and damage to the genital area from fluctuations.

4. Reduced Friction: Cyclists should limit riding time to minimize genital friction and discomfort.


Women's vaginal health is paramount, necessitating adoption of healthy practices to mitigate risks of moistness and odor. By understanding physiological and pathological causes and implementing preventive measures, women can sustain vaginal health, alleviate discomfort, and manage common concerns effectively.
