  • Title: Company improves condoms by adding spermicide.
    Journal: Contracept Technol Update; 1982 Aug; 3(8):103-4. PubMed ID: 12265537.
    Abstract:
    US Food and Drug Administration (FDA) marketing approval for a condom coated with the spermicide nonoxyno1-9 is expected to be granted this fall according to Lillian Yin of the FDA. The marketing request was submitted by Schmid Laboratories of Little Falls, New Jersey. The spermicide coating on the condom quickly inactivates sperm, and these condoms, therefore, are expected to increase the effectiveness of condoms when sperm spillage occurs following condom failure or misuse. The capability of the coating to inactivate sperm was assessed in an Emory University study of 30 men, aged 19-46, who ejaculed into condoms coated with the spermicide and into noncoated condoms. For the condoms without the coating, 50% of the sperm remained active for 20 minutes following ejaculation. For the condoms with the coating, only 10% of the sperm remained active 30 seconds after ejaculation and only 1.5% remained motile after 120 seconds elapsed. The spermicide dose in the condom is considerably less than the dose of spermicide recommended for vaginal use since the condom concentrates the sperm in one location while vaginal spermicide must be capable of immobilizing sperm throughout the vaginal vault. The use effectiveness of the spermicidal coated condom has not be assessed for the US population. A study of 397 couples in England who used a similar spermicidal coated condom over a 2-year period yielded a Pearl Index failure rate of 0.83 pregnancies/100 years of use. This rate is lower than that normally associated with condoms. In the US, however, condoms are widely used among teenagers, and teenagers may be more likely to use the condom incorrectly. Furthermore, the availability of a spermicidal condom may discourage teenagers and others from taking the added precaution of using vaginal contraceptives in combination with the condom. The FDA recommended that the label on the condom package can inform the user that the product may help reduce the risk of pregnancy in the event of condom failure or misuse; however, the FDA said that the label cannot indicate that the product is a substitute for the method of combining a condom and vaginal spermicide. A potential side effect of the device is penile irritation, but the men in the Emory University study experienced no side effects.
