vaginal ring

A small silicone ring, known as the dapivirine ring, may protect as many as 75 percent of women using it from contracting HIV, the virus that leads to AIDS. The ring is inserted into the vagina and infused with a special antiviral drug, called dapivirine. Researchers say the findings are especially important in countries where there is a cultural taboo for women refusing sex, even with their husbands, and may not have a say in whether or not he wears a condom.
