Will itching caused by pubic hair rubbing against the genitals cause inflammation?

Many people will find that their lower body is not as easy to care for as in childhood after adulthood. If they are not careful, it will cause inflammation and infection. Some people will feel local itching when the pubic hair rubs. This can be considered as a little folliculitis, which is generally caused by many problems due to bacterial infection.

Cause details/vaginitis

1. Bacterial vaginosis

In a normal vagina, lactobacilli that produce hydrogen peroxide are dominant. Bacterial vaginosis is an endogenous mixed infection caused by a decrease in Lactobacillus and an increase in Gardnerella and anaerobic bacteria in the vagina.

2. Candidal vaginitis

1) 80% to 90% of pathogens are Candida albicans, which grow easily in an acidic environment and are diphasic bacteria (yeast phase and hyphae phase).

2) The patient's vaginal pH is between 4.0 and 4.7, often <4.5.

3) Conditionally pathogenic bacteria (yeast phase → mycelium phase).

4) Common causes: pregnancy, diabetes, and extensive use of immunosuppressants and broad-spectrum antibiotics.

5) Other causes: gastrointestinal Candida, wearing tight synthetic underwear, and obesity.

3. Trichomonas vaginitis

1) Trichomonas vaginalis grows best in a humid environment with a temperature of 25℃~40℃ and a pH of 5.2~6.6.

2) The vaginal pH changes before and after menstruation, becoming close to neutral after menstruation, making it easy for Trichomonas to reproduce.

3) The patient's vaginal pH is generally between 5.0 and 6.5, and most are >6.0.

4) Parasitizes in the vagina, urethra or paraurethral glands, bladder, renal pelvis, male foreskin folds, urethra, and prostate.

5) Often coexists with other vaginitis.

4. Senile vaginitis

Postmenopausal women have declining ovarian function, lower estrogen levels, vaginal wall atrophy, thinning mucosa, increased vaginal pH, reduced local resistance, and other pathogenic bacteria may over-multiply or easily invade and cause inflammation, mainly aerobic bacteria.
