This overview provides a discussion of the special concerns of sexually transmitted diseases (STDs) for women, particularly because of its asymptomatic character; screening; primary prevention; e.g., abstinence, selection of sexual partners restriction of sexual activities, use of barriers (condoms, vaginal spermicides, diaphragm in conjunction with spermicides), and vaccines; and the role of the gynecologist in StD prevention. Gonorrhea and chlamydial infection are usually asymptomatic STD infections in women; long term sequelae are pelvic inflammatory disease (PID), infertility, and pregnancy complications. There is an increased risk of cervical cancer. Infection is lifelong for herpes simplex virus (HSV) and HIV and malingering for chronic hepatitis B (HPB). Genital human papillomavirus (HPV) and HSV infections cannot be identified serologically. The fetus can be fatally or severely affected by STDs. Abstinence is the only effective prevention for STDs. Likelihood of infection may be reduced by limiting partners, but how partners are chosen and knowledge of infection is a more important determinant. Partners need to be asked about current symptoms, history of STDs, multiple partners, and history of known STD partners, as well as past history of homosexual activity, intravenous drug use, hemophilia, and previous exposure to high-risk persons for STDs. Visible genital warts or lesions, wartlike growths, ulcers, or rash need explanations. Avoidance of oral anal and digital anal activity reduces transmission of hepatitis A, giardiasis, amebiasis, and shigellosis. Any mechanical barrier that remains intact should reduce the risk of STD; barriers specifically covering the cervix are excellent. Condom use is effective when used as follows: 1) at the onset of sexual activity, 2) without petroleum jelly or baby oil on latex, 3) with care of fingernails which may tear holes, 4) with complete withdrawal of the penis before complete detumescence, and 5) with a withdrawal hold at the base of the penis. Spermicides, such as nonoxynol 9, are effective against STDs. Diaphragm use with spermicide may be effective because of the spermicide. There is a reduced risk of transmission of HSV or HPV to a partner. Vaccines are only available for hepatitis B. Obstetrics and gynecology residency training in STDs in unavailable in 4 out of 5 medical schools, and gynecologists are ethically obligated to accurately inform about STD diagnosis, treatment, and diagnosis.
