Is it treatable if a man has pubic lice on the scrotum?
Generally, male genital pubic lice can be completely cured with timely and standardized treatment; however, delays or incomplete management may lead to recurrence. If any abnormalities occur, prompt medical consultation is recommended. Detailed analysis is as follows:

In the early stage of pubic lice infestation, the parasites and their eggs are primarily concentrated in the pubic hair area. Removing pubic hair destroys their living environment, and when combined with topical medications such as sulfur ointment or lindane lotion, residual parasites can be effectively killed. Washing the affected area daily with warm water and changing into disinfected underwear typically enables most patients to eliminate the pathogen within 1–2 weeks.
If pubic hair is not thoroughly removed, clothing and bedding are not properly sterilized at high temperatures, or sexual partners do not receive concurrent treatment, residual eggs or re-infestation may occur. In some patients, scratching due to itching can cause skin damage, potentially leading to secondary bacterial infections and prolonging the treatment period.
During treatment, underwear should be changed daily and disinfected by boiling. Bed sheets and quilts should be thoroughly sun-dried. Sexual partners should also undergo examination and treatment simultaneously to prevent cross-infection. After completing the treatment course, a follow-up examination is necessary to confirm the absence of remaining parasites.
