Blisters in the male genital area are mostly genital herpes. This is caused by infection with the herpes simplex virus type 2 and is clinically a sexually transmitted disease. It is generally contracted through direct sexual contact. Once this disease occurs, it is generally not possible to completely eradicate it, and the virus will be carried for life. During an outbreak, antiviral medications can be used for treatment, such as taking oral acyclovir tablets and applying acyclovir ointment. Recovery generally takes about a week. However, recurrences can occur if immunity decreases or if one consumes spicy and irritating food. Some patients may trigger the disease with every sexual encounter, so it is essential to maintain proper dietary and lifestyle habits. (Use medication under the guidance of a doctor)
