Common causes of STDs

　　sexually transmitted diseases is harmful to many men and women healthy an infectious disease disease , but most people don’t know much about how this disease is infected. Here are some common causes of STDs for your reference.

　　contraceptive measures

　　Multiple studies have shown that condoms can block HPV infection, so consistent use of condoms can prevent the occurrence of CA. Another study shows that the incidence of CA in women taking birth control pills is higher than that in those who do not take pills.

　　sexual behavior

　　Research and statistics show that the probability and recurrence rate of CA in people with multiple sex partners are significantly higher than those with a single sex partner; within a certain range, the age of sexual intercourse is also a risk factor for CA. For those who have first sexual intercourse younger than 19 years old, their incidence and recurrence rates are significantly increased; male Commercial sex workers are a high-risk group for CA.

　　immune function

　　Data show that individuals with low immunity such as kidney transplants, malignant tumors, diabetes, AIDS , immunosuppressive chemotherapy and the use of glucocorticoids, etc., the incidence and recurrence rate of CA are significantly increased, and the wart volume is also larger.

　　smoking

　　Because smoking can reduce the body's resistance, smoking is also an independent risk factor for CA. Studies have shown that the incidence of CA in smokers is more than three times higher than that in non-smokers, and the incidence increases with smoking age and the number of cigarettes smoked per day. At the same time, smoking can promote the recurrence of CA.

　　age and gender

　　Age is an independent risk factor for CA. 80% of CA occurs in young people aged 16 to 34 years old, and the peak age of incidence is 20 to 25 years old. The average age of onset in men is 22 years old. female 19 years old; the male to female incidence ratio is about 1:1.4. Another study found that women younger than 25 years old were the cause of anal genital warts.

　　Have other sexually transmitted diseases

　　CA is closely related to other sexually transmitted diseases such as genital herpes, gonorrhea, syphilis, AIDS, etc. The first reason is that many CA patients have risky sexual behaviors that can also lead to other sexually transmitted diseases. Second, some sexually transmitted disease pathogens destroy the mucosal barrier, reducing the body's ability to resist HPV.

　　marital pregnancy status

　　Data show that divorced, separated, widowed, and unmarried people have a higher incidence of CA than normal controls because high-risk sexual behaviors are prone to occur under these circumstances. Pregnant women have a higher incidence of CA, and the recurrence rate of CA is relatively high, which is related to the changes in endocrine function during pregnancy.
