A vaginal spermicidal sponge, made of polyurethane and containing nonoxynol-9, is expected to be on the market in Fall 1983. It will be sold under the name "Today" and will cost about $1 each. US Food and Drug Administration (FDA) approval of marketing of the sponge was obtained in March 1983. The device, which was developed by the VLI Corporation, is already marketed in the UK. Among the unique features of the sponge are the following: 1) an absence of potential adverse systemic side effects; 2) 1 universal size, eliminating the need for professional fitting or prescription; 3) ease of insertion and removal; 4) over-the-counter marketing; 5) the possibility of multiple acts of coitus during the recommended 24-hour wearing time, without additional preparation; 6) the combination of spermicidal activity with a barrier method of contraception; 7) no need to wait after insertion; 8) the opportunity for sponge insertion hours in advance of intercourse; 9) disposability; and 10) lack of leakage of excess medication during and after coitus. Research studies involving about 2000 women worldwide found the sponge's effectiveness to be in the range of other vaginal contraceptives. An overall failure rate of about 10-18% is claimed. Fewer than 2% of users in clinical trials experienced irritation; however, persons sensitive to spermicides may have an allergic response. Sponge use will be monitored to determine whether there is a risk of toxic shock syndrome. Other concerns center on the use of polyurethane and the possible presence of carcinogenic compounds. Studies of possible 48-hour use are in process. Noncontraceptive benefits are expected to emerge with more widespread use. 1 study suggested that nonoxynol-9 offers some protection against gonorrhea and other sexually transmitted diseases.
