Some people are troubled by “blossoms” because they have “genital warts,” the official name for genital warts, which are caused by the human papillomavirus (HPV). It is caused by the human papillomavirus (HPV). The virus can take advantage of the small wounds on the skin or mucous membranes during sexual intercourse, and then it can sneak into the epidermal cells and multiply, causing infection. The incubation period is about three to four months, but sometimes it can be as long as one or two years. The majority of genital warts occur in the vicinity of the external genitalia, commonly in the glans, foreskin, coronal sulcus, penis, pubic bone, scrotum and perineum in men, and mainly in the labia majora and minora in women. In recent years, due to the complexity and diversity of sexual behavior, “cauliflower” near the anal opening and in the oral cavity is also occasionally seen. The lesions are usually flat, pink to brown, smooth or verrucous papules of one to three millimeters in size, located on the general skin, and are scattered or clustered. Sometimes the papules may fuse to form large plaques or even hyperkeratosis. In the mucous membrane, the warts are often finger-like, and can be as small as a pencil tip or as large as a cauliflower, a true “cauliflower”. If left untreated, genital warts can spread to the urethra, anus and rectum in men, and to the vagina, cervix, anus and rectum in women. Furthermore, it is now known that cervical cancer in women and penile cancer in men are both strongly associated with HPV infection. Therefore, if genital warts are not treated aggressively, they may cause serious consequences for yourself and your partner.
