The difference between true and false male sexual acuity

When male friends are examined, the virus will be detected. At this time, they will be very worried, afraid that they may have genital warts. In fact, the virus is divided into true and false genital warts, and the treatment methods for different symptoms are completely different. If the patient has a more chronic disease, it will be more difficult to treat, and it may even be possible that the treatment is not in time.

1. Acetic acid whitening experiment

Applying 3% to 5% acetic acid solution topically or wet compressing for 5 to 10 minutes can cause whitening in the HPV-infected area, the so-called "acetowhitening phenomenon". However, the specificity is not high, and some chronic inflammations, such as candidal vulvitis, genital trauma and non-specific inflammation, can cause false positives.

2. Cytological examination

When vaginal or cervical wart tissue smears are stained with Papanicolaou, two types of cells can be seen, namely vacuolated cells and dyskeratotic cells, which are of diagnostic value for condyloma acuminatum.

3. Histopathological examination

The presence of vacuolated cells above the spinous layer and in the granular layer is important evidence for the diagnosis of HPV infection.

4. Immunological tests

Antibodies against HPV proteins are used to detect HPV antigens in diseased tissues. This method is not very sensitive, with a detection rate of only about 50%.

5. Nucleic acid hybridization test

It is an important means of detecting HPV infection, including dot blot hybridization, tissue in situ hybridization, and nucleic acid imprinting (Southern blot hybridization). These methods have high specificity and sensitivity and are sensitive and reliable methods for diagnosing HPV infection. However, the technical operation is cumbersome and has not been widely used in clinical practice.

6. Polymerase chain reaction (PCR)

It is currently the most sensitive method for detecting HPV infection and can also perform type-specific analysis. It has the characteristics of high sensitivity, simplicity and rapidity. It has been widely used in clinical practice.

Genital and perianal areas are the most common sites. In men, it is more common in the foreskin, frenulum, coronal sulcus, glans penis, urethral orifice, penis body, perianal area, rectum and scrotum. In women, it is more common in the labia majora and minora, posterior symphysis, vestibule, clitoris, cervix and perianal area. Occasionally, it can be seen in areas other than the genitals and perianal area, such as the axilla, umbilical fossa, oral cavity, breasts and between toes. Female vaginitis and male prepuce hyperplasia are the factors that promote the occurrence of condyloma acuminatum.
