Experts confirmed that semen or vaginal secretions in HIV infected with the AIDS virus, sex with male and female reproductive organs when there may be bleeding injury, so the sexual contact can spread aids.

In Nanjing has reported HIV infected persons, the proportion of sexually transmitted has reached 41.5%, accounting for the first route of transmission. In Tianjin, the main route of transmission of sexually transmitted infections, sexually transmitted diseases, accounting for 33.6%, of which heterosexual transmission accounted for about 27.3%, male homosexual transmission accounted for 6.39%. Guangxi autonomous region of the 121 pairs of voluntary counseling and testing of the couple's serum testing, found through sexual partners in the spread between husband and wife have 84 pairs. If one of the parties is infected with HIV, the AIDS virus can be transmitted to the other side through the sexual life between husband and wife, many innocent men and women in this way and HIV infection.
