Worms on the lower body of men should refer to pubic lice disease, which can be caused by men through sexual contact or sharing items with a person with pubic lice disease. Pubic lice are found in the private parts of the body and are highly contagious. If a man has sex with a person who has pubic lice, he may be infected by the lice on the other person’s body, which can lead to pubic lice disease. Men who do not pay attention to personal hygiene and share towels, bed sheets and clothes with someone who has been infected with pubic lice may also suffer from pubic lice. It is recommended that men keep themselves clean and hygienic, change their personal clothing regularly, and avoid unclean sex. If there are such symptoms, it is recommended to go to the hospital in time and under the guidance of the doctor for treatment.
