If women present to labor and delivery without documented negative serology at 36 weeks, rapid intrapartum testing should be performed. This does not need to include viral load determination, because fourth-generation screening protocols are sufficiently sensitive and have a lower false-positive rate. As a high-risk patient, first- and third-trimester screening is appropriate. Recommendations are to review and encourage safe sexual practices, including consistent use of barrier contraception, preexposure prophylaxis (PrEP), and a plan for HIV screening. HIV-uninfected pregnant women with HIV-infected partners may present for consultation. Bernstein, in Obstetrics: Normal and Problem Pregnancies (Seventh Edition), 2017 Human Immunodeficiency Virus Discordant Couples On the other hand, increased use of these methods would reduce opportunities for the application of preventive medicine to women of childbearing age since these methods do not require medical supervision.Helene B. New innovations could make barrier methods of contraception more attractive and acceptable to couples. Little has been done to improve the image or packaging of diaphragms and caps. Diaphragms are currently one of the least frequently used forms of contraception, in part because of the messiness of the spermicide. Vaginal sponges are less messy than caps and diaphragms, are unlikely to have adverse systemic effects, and can be purchased over the counter without medical consultation. The collatex sponge represents the only marketed recent advance in barrier contraception.

Present commercially available spermicides appear to be free of serious side effects however, since many drugs can be absorbed into the systemic circulation from the vagina, new preparations must be carefully tested for toxic effects. Although condom distribution campaigns have led to a dramatic decrease in the number of cases of sexually transmitted disease, those whose lifestyles put them at highest risk of contracting these diseases are least likely to accept condoms. Major advances have been made in condom marketing and manufacturing techniques. Such methods may protect against sexually transmitted diseases and carcinoma of the cervix. Recent evidence suggesting adverse effects from IUD and oral contraceptive use has led to renewed interest in barrier contraception.
This article reviews current knowledge regarding the effectiveness and safety of barrier contraception (condoms, spermicides, vaginal sponges, the diaphragm, and cervical caps).
This would have many advantages, but could also detract from the ability of family planning clinics to play an important role in preventative medicine for women. The new surge of interest in barrier contraception could lead to safer more effective forms of contraception being made available to women without medical supervision. This is unlikely to make it the first choice of contraception for couples who would find an unintended pregnancy a severe problem, but the sponge will be acceptable to couples who are simply trying to delay a pregnancy. Effectiveness rates range between 9 and 27 pregnancies per 100 woman-years. The only marketed recent advance in barrier contraception is the collatex sponge. This must make it an attractive form of contraception for agencies supporting family planning programmes in developing countries. Distribution and education in the use of barrier contraception does not always require medical supervision. The use of barrier contraception may protect against carcinoma of the cervix and sexually transmitted diseases. Barrier contraception is a safe, effective, reversible form of contraception acceptable to many couples.
