What is the reason for small blisters on the glans penis? Small blisters on the male genitals are common in men with long foreskin. However, most of the small blisters on the male genitals are caused by sexual organ infections. For men who have unclean sex, they should be alert to the possibility of genital herpes. For men who have not had sex, most of the causes are balanitis.

1. Genital herpes

Genital herpes is a common manifestation of genital tract infection, mostly caused by viral infection. Genital herpes usually has obvious small blisters. Genital herpes mostly occurs at the junction of the skin and mucous membranes. At first, some skin turns slightly red, and then a large number of small blisters the size of a needle spread out, with a slight itching and burning feeling.

2. Balanitis

Balanitis is a common male reproductive organ infection in men's health. The main symptoms of balanitis are redness and swelling of the foreskin, burning pain, aggravated during urination, and purulent secretions discharged from the foreskin. If the foreskin is rotated, it can be seen that the inner plate of the foreskin and the glans penis are bloody and swollen. In severe cases, there will be shallow ulcers or erosions, and small bubbles.

3. Scrotal eczema

Scrotal eczema is a common type of eczema, limited to the scrotal skin, sometimes extending to the area around the anus, and rarely to the genitals. The clinical symptoms of scrotal eczema include focal redness, swelling, and severe itching of the scrotal skin, and the presence of numerous needle-sized to millet-sized papules and blisters.
