How to check for bacterial vaginosis in men

We know that there are many causes of bacterial vaginosis, so many women suffer from this disease in life. Patients often feel itching, pain, and unpleasant odor in the vagina, which brings great pain and inconvenience to women's lives. So how to check for bacterial vaginosis? Let's introduce it to you below.

According to clinical manifestations, this disease is more common in women of childbearing age. It is often treated as nonspecific or other bacterial vaginosis and is not cured. The persistent leucorrhea increases with a peculiar smell (rotten or fishy). A few patients may have mild vulvar itching and burning sensation. At present, the examination criteria for bacterial vaginosis are:

(1) Vaginal secretions increase, are uniform and thin, and often adhere to the vaginal wall.

(2) Vaginal pH > 4.5 (pH is usually 4.7-5.7, mostly 5.0-5.5).

(3) Amine odor test (whifftest) is positive. Take a small amount of vaginal secretions and place them on a glass slide. Add 1-2 drops of 10% potassium hydroxide. A fishy smell like rotten fish is produced. This is due to the release of ammonia by amines when they come into contact with alkali.

(4) Clue cell positive: Clue cells are the surface cells that fall off the vaginal stratified squamous epithelium. A large number of granules formed by Gardnerella adhere to the cell edges, and the edges are blurred. Clue cells account for more than 20% of all epithelial cells, which is considered clue cell positive;

(5) Proline aminopeptidase positive: The activity of proline aminopeptidase in vaginal secretions is measured by enzyme-linked immunosorbent assay (ELISA). Orange or red indicates positive for bacterial vaginosis, while yellow indicates negative.

(6) Gram staining standard examination: Gram staining method, microscopic examination to find the characteristic morphological changes of BV flora, can be used as a method of BV examination. Vaginal Gardnerella culture is not recommended as it is not specific enough.
