Develop and improve products. List of Partners vendors. A spermicide is any compound that can be used to kill sperm. Spermicides are used in many contraceptives and come in several forms. Contraceptive foams, creams, suppositories, and films all contain spermicides. Furthermore, spermicides are needed for diaphragms and cervical caps to be effective.
Many spermicides currently available in the United States contain nonoxynol-9 N N-9 is also the spermicide in the Today sponge. Other spermicides and spermicidal microbicides are currently under development. Many are being designed to avoid the problems currently being seen with N-9 use.
Condoms with spermicidal lube used to be a pretty common option for safe sex. However, that began to change once people started to become aware of the potential dangers of N-9 use. N-9 is basically a type of detergent. It disrupts the plasma membranes outer barrier of sperm and other cells. Scientists once believed N-9 to be effective at destroying STD pathogens, including HIV, herpes , chlamydia , and gonorrhea , but current research no longer supports this theory.
Other commercial spermicides that contain N-9 are also detergents. These products have similar properties to N Many people think that if a little bit of spermicide is good, then a lot of spermicide is bound to be better. However, that theory is actually incorrect. It turns out that many spermicides, when used in excess, can make sex more hazardous. They can actually increase your risk of getting or giving someone a sexually transmitted disease STD. N-9 causes inflammation of the vagina and cervix.
That damage increases susceptibility to infection by STDs and the likelihood of transmitting them. Some people may experience problems with even infrequent use. If you're using a diaphragm, cervical cap, or the Today sponge for contraception and you're at high risk of sexually transmitted infections, talk to your healthcare provider about possible alternative forms of contraception.
Not everyone needs to worry about N However, it's good to have other options for practicing safe sex. There is no reason to choose a condom with spermicide over one without it. According to Planned Parenthood , when talking about just spermicide, it can be effective at preventing pregnancy when compared to using not birth control at all.
But, the organization notes, it's difficult to use correctly. About 28 out of women who use spermicide become pregnant every year, the Centers for Disease Control and Prevention CDC says —compare that to 22 women who get pregnant using withdrawal, a notoriously risky birth control method.
The most common spermicide is nontoxynol-9 N-9 , which works by inhibiting the motility of the sperm—basically, making it more difficult for them to swim. Brahmbhatt, adding that those results led many condom makers to begin using N But later research refuted the benefit.
