at the initial stage of HPV infection, men usually go through an incubation period, during which there is no local change and there will be no skin lesion proliferation. After the incubation period of HPV virus, some small, reddish rashes will begin to appear at the infected site, which will gradually increase and grow into typical characteristics of condyloma acuminatum such as vegetable pattern and cockscomb.
